为了改善转缸压缩机在运行过程中,法兰结构不具有消音功能,同时法兰结构由于安装不稳定产生振动噪音的问题,本公开提供一种法兰结构、泵体组件和流体机械。In order to improve the problem that the flange structure does not have a noise reduction function during the operation of the rotary cylinder compressor, and the flange structure generates vibration and noise due to unstable installation, the present disclosure provides a flange structure, a pump body assembly and a fluid machine.
其中,流体机械包括下述的泵体组件,其中,下述的法兰结构为下述泵体组件的一部分。具体的,流体机械为压缩机。在一些实施例中,压缩机是转缸压缩机。The fluid machine includes the following pump body assembly, wherein the following flange structure is a part of the following pump body assembly. Specifically, the fluid machine is a compressor. In some embodiments, the compressor is a rotary cylinder compressor.
如图4至图5所示,法兰结构朝向气缸套40的一侧开设有消音通道,消音通道沿法兰结构的周向延伸,法兰结构还包括法兰排气孔5011,法兰排气孔5011与消音通道连通。As shown in FIG. 4 to FIG. 5 , the side of the flange structure facing the cylinder liner 40 is provided with a muffler channel, and the muffler channel extends along the circumferential direction of the flange structure. The flange structure further includes a flange exhaust hole 5011, and the flange row The air hole 5011 communicates with the muffler passage.
由上可知,从以上的描述中,可以看出,本公开上述实施例中,通过在法兰结构的一侧设置周向延伸的消音通道,以使现法兰结构具有消音功能,周向延伸的消音通道增大了气体的流动路径,有效减小了气体流动的噪音。现有的转缸压缩机需要与消音器配合使用以进行降噪消音,现有的转缸压缩机的法兰结构不具有消音功能。As can be seen from the above, from the above description, it can be seen that in the above-mentioned embodiments of the present disclosure, a circumferentially extending silencing channel is arranged on one side of the flange structure, so that the existing flange structure has a silencing function, which extends circumferentially. The muffler channel increases the flow path of the gas and effectively reduces the noise of the gas flow. The existing rotary cylinder compressor needs to be used in conjunction with a muffler for noise reduction and noise reduction, and the flange structure of the existing rotary cylinder compressor does not have a noise reduction function.
具体地,泵体组件产生的高压气体流入到法兰结构的消音通道内,并沿着消音通道周向流动,流动至法兰排气孔5011处,经法兰排气孔5011排出。有效降低了气动声噪,以使法兰结构具有消音功能。Specifically, the high-pressure gas generated by the pump body assembly flows into the muffler channel of the flange structure, flows along the circumferential direction of the muffler channel, flows to the flange exhaust hole 5011 , and is discharged through the flange exhaust hole 5011 . The aerodynamic noise is effectively reduced, so that the flange structure has the function of silencing.
在本公开中,法兰结构上的消音通道可以连通(非阻断式),也可以不连通(阻断式),以能使法兰结构通过设置消音通道达到降低噪音的效果为准。In the present disclosure, the silencing channels on the flange structure may be connected (non-blocking type) or not (blocking type), whichever can be achieved by providing the silencing channels on the flange structure to reduce noise.
在图4所示的具体实施例中,消音通道是一个连续的通道,并没有设置阻断结构5021(示出在图5中,图5给出了具有阻断结构的消音通道,需要在后面单独介绍,这里就不赘述了)。In the specific embodiment shown in FIG. 4 , the silencing channel is a continuous channel, and no blocking structure 5021 is provided (shown in FIG. 5 , which shows the silencing channel with blocking structure, which needs to be followed by It is introduced separately and will not be repeated here).
需要说明的是,在如图4所示的具体实施例中,消音通道可以由一个连续的消音凹槽5031构成,也可以由多个消音凹槽5031构成。当消音通道由多个消音凹槽5031构成时,多个消音凹槽5031沿法兰结构的周向间隔设置,且相邻两个消音凹槽5031通过连通孔连通,多个消音凹槽5031配合构成一个消音通道。多个消音凹槽5031的形状可以至少一部分相同,也可以均不相同,由于组合形式较多此处不一一列举。消音凹槽5031设置在法兰结构的侧面,以使泵体组件的高压气流流经消音凹槽5031后排出法兰结构,对高压气体进行消音降噪。It should be noted that, in the specific embodiment shown in FIG. 4 , the muffler channel may be constituted by one continuous muffler groove 5031 , or may be composed of a plurality of muffler grooves 5031 . When the muffler channel is composed of a plurality of muffler grooves 5031, the plurality of muffler grooves 5031 are arranged at intervals along the circumferential direction of the flange structure, and two adjacent muffler grooves 5031 are communicated through communication holes, and the plurality of muffler grooves 5031 cooperate with each other. form a silencer channel. The shapes of the plurality of sound-absorbing grooves 5031 may be at least partially the same, or may be different in all, since there are many combinations, they will not be listed here one by one. The muffler groove 5031 is arranged on the side of the flange structure, so that the high-pressure air flow of the pump body assembly flows through the muffler groove 5031 and then exits the flange structure, so as to muffle and reduce the high pressure gas.
如图4所示,消音凹槽5031的侧壁具有向法兰结构的中心轴突出的筋状结构,筋状结构为多个,多个筋状结构沿消音凹槽5031的侧壁间隔设置,以使消音通道具有交替设置的宽过流区域和窄过流区域。As shown in FIG. 4 , the side wall of the muffler groove 5031 has a rib-like structure protruding toward the central axis of the flange structure, and there are multiple rib-shaped structures, and the plurality of rib-shaped structures are arranged along the side wall of the muffler groove 5031 at intervals. In order to make the muffler channel have alternately arranged wide and narrow over-current regions.
具体地,通过设置在消音通道的侧壁上的多个间隔设置的筋状结构,以使消音通道内部形成具有交替设置的宽过流区域和窄过流区域。当气体流到消音通道内部时,气体经过多个间隔设置的宽过流区域和窄过流区域时进行多次节流、膨胀,以降低噪音。Specifically, a plurality of rib-like structures arranged on the side wall of the muffler passage at intervals are used to form the inside of the muffler passage with alternately arranged wide flow regions and narrow flow regions. When the gas flows into the muffler passage, the gas undergoes multiple throttling and expansion when passing through a plurality of spaced wide flow regions and narrow flow regions to reduce noise.
在本公开中,筋状结构的个数大于3个且小于5个。多个筋状结构使消音通道形成具有交替设置的宽过流区域和窄过流区域,以增加节流、膨胀的次数,需要说明的是,节流和膨胀的次数并不是越多越好,当筋状结构的个数大于3个且小于5个具有降噪消音的功能。在本实施例中,筋状结构的个数为3个。In the present disclosure, the number of tendon structures is greater than 3 and less than 5. Multiple rib-like structures form the muffler channel with alternately arranged wide over-flow areas and narrow over-flow areas to increase the times of throttling and expansion. It should be noted that the more times of throttling and expansion, the better. When the number of tendon structures is more than 3 and less than 5, it has the function of noise reduction and noise reduction. In this embodiment, the number of tendon structures is three.
需要说明的是,各筋状结构与法兰结构的中心轴之间的距离可以是相等。多个筋状结构以法兰结构的中心轴为中心设置在消音通道内部,且距离法兰结构的中心轴相等,以增强消音效果。当然,也不是所有的筋状结构与法兰结构的中心轴之间的距离都必须相等。不同的筋状结构与法兰结构的中心轴之间的距离可以是部分不同,也可以是全部不同的, 这里就不一一进行列举了,主要是以能够实现消音功能为基础,合理设置筋状结构与法兰结构的中心轴之间的距离。It should be noted that the distance between each rib-shaped structure and the central axis of the flange structure may be equal. A plurality of tendon structures are arranged inside the muffler channel with the central axis of the flange structure as the center, and are equal to the central axis of the flange structure, so as to enhance the muffler effect. Of course, not all rib-like structures have to be at the same distance from the central axis of the flange structure. The distance between the central axis of the different rib-like structures and the flange structure may be partially different or completely different, which will not be listed here. The distance between the central axis of the flange structure and the flange structure.
如图6所示,法兰结构具有法兰孔,法兰孔与法兰结构的中心轴偏心设置,法兰结构的中部具有轴颈5071,轴颈5071由开设消音通道后的部分构成,法兰孔贯穿轴颈5071的轴向端面,轴颈5071的外周圆与法兰结构的外周圆同轴。As shown in Figure 6, the flange structure has a flange hole, the flange hole and the central axis of the flange structure are eccentrically arranged, the middle of the flange structure has a journal 5071, and the journal 5071 is composed of the part after the noise reduction channel is opened. The flange hole runs through the axial end face of the journal 5071, and the outer circumference of the journal 5071 is coaxial with the outer circumference of the flange structure.
具体地,轴颈5071具有柔性支撑的作用,可减小集中应力,减小法兰结构的磨损,提高法兰结构的稳定性。Specifically, the journal 5071 has the function of flexible support, which can reduce the concentrated stress, reduce the wear of the flange structure, and improve the stability of the flange structure.
如图6所示,轴颈5071背离气缸套40的一侧具有突出于法兰结构的端面的凸环结构,以使法兰结构的轴向上的总高度H大于法兰结构的轴向上的两端面之间的高度H1,消音通道在法兰结构的轴向上的高度H2小于法兰结构的轴向上的两端面之间的高度H1。As shown in FIG. 6 , the side of the journal 5071 facing away from the cylinder liner 40 has a convex ring structure protruding from the end face of the flange structure, so that the total height H of the flange structure in the axial direction is greater than the axial direction of the flange structure The height H1 between the two end faces of the silencing channel in the axial direction of the flange structure H2 is smaller than the height H1 between the two end faces of the flange structure in the axial direction.
具体地,当法兰结构的轴向上的高度H2大于H1时,此时消音通道的深度足够大,以保证进入到消音通道内部的气体能够在消音通道内流动并降低噪音。当法兰结构的轴向上的高度H2小于H1时,此时消音通道的深度过小无法有效实现降噪的效果。Specifically, when the height H2 of the flange structure in the axial direction is greater than H1, the depth of the muffler passage is large enough to ensure that the gas entering the muffler passage can flow in the muffler passage and reduce noise. When the height H2 in the axial direction of the flange structure is less than H1, the depth of the muffler channel is too small to effectively achieve the effect of noise reduction.
需要说明的是,0.5H<H1<0.9H,0.3H<H2<0.7H。当法兰结构的轴向上的两端面之间的高度H1和法兰结构的轴向上的高度H2分别于法兰结构的轴向上的总高度H的大小关系保持在上述范围内,可有效降低噪音且可减小集中应力,减小磨损提高稳定性。It should be noted that 0.5H<H1<0.9H, 0.3H<H2<0.7H. When the relationship between the height H1 between the two end faces in the axial direction of the flange structure and the height H2 in the axial direction of the flange structure and the total height H in the axial direction of the flange structure is maintained within the above range, it can be Effectively reduce noise, reduce concentrated stress, reduce wear and improve stability.
如图6所示,法兰结构的侧壁厚度L1、法兰结构的端面厚度L2满足如下的关系:0.05H<L1<0.25H;0.1H<L2<0.4H。As shown in Figure 6, the thickness L1 of the side wall of the flange structure and the thickness L2 of the end face of the flange structure satisfy the following relationship: 0.05H<L1<0.25H; 0.1H<L2<0.4H.
具体地,法兰结构的侧壁厚度L1过小时,影响法兰结构的刚度,法兰结构的侧壁厚度L1过大时,影响消音效果;法兰结构的端面厚度L2过小时,影响法兰结构的刚度,法兰结构的端面厚度L2过大时,影响消音效果,合理的端面厚度可以保证消音效果。Specifically, if the side wall thickness L1 of the flange structure is too small, the stiffness of the flange structure will be affected; if the side wall thickness L1 of the flange structure is too large, the noise reduction effect will be affected; if the end face thickness L2 of the flange structure is too small, the flange structure will be affected. When the rigidity of the structure and the end face thickness L2 of the flange structure are too large, the noise reduction effect will be affected. A reasonable end face thickness can ensure the noise reduction effect.
如图6和图8所示,消音通道的侧壁具有向法兰结构的中心轴突出的筋状结构,轴颈的轴向端面的最小厚度L3与筋状结构至轴颈的中心k2之间的距离R3之间的关系为0.05H<L3<R3。As shown in Figures 6 and 8, the side wall of the muffler channel has a rib-like structure protruding toward the central axis of the flange structure, and the minimum thickness L3 of the axial end face of the journal is between the rib-like structure and the center k2 of the journal. The relationship between the distance R3 is 0.05H<L3<R3.
具体地,筋状结构影响高压气体的节流膨胀,合理的轴颈5071的轴向端面的最小厚度与筋状结构至法兰结构的中心轴之间的距离R3,可以保证法兰结构刚度的同时,加强降噪效果。Specifically, the rib-shaped structure affects the throttling and expansion of the high-pressure gas. A reasonable minimum thickness of the axial end face of the journal 5071 and the distance R3 between the rib-shaped structure and the central axis of the flange structure can ensure the rigidity of the flange structure. At the same time, the noise reduction effect is enhanced.
如图8所示,法兰结构的中部具有轴颈,轴颈的中心k2与法兰结构的法兰轴孔中心k1之间具有偏心量e,法兰结构的法兰轴孔中心k1与消音凹槽的外侧槽壁之间的距离为R1,筋状结构至轴颈的中心k2的距离为R3,由轴颈的中心k2至消音凹槽的内侧槽壁之间的距离为R2,且R1、R2、R3之间满足如下关系:0.1<(R1-R2)/(R3-R2)<0.4。在本实施例中,0.15<(R1-R2)/(R3-R2)<0.25。As shown in Figure 8, there is a journal in the middle of the flange structure, and there is an eccentricity e between the center k2 of the journal and the center k1 of the flange shaft hole of the flange structure. The distance between the outer groove walls of the groove is R1, the distance from the tendon structure to the center k2 of the journal is R3, the distance from the center k2 of the journal to the inner groove wall of the muffler groove is R2, and R1 , R2 and R3 satisfy the following relationship: 0.1<(R1-R2)/(R3-R2)<0.4. In this embodiment, 0.15<(R1-R2)/(R3-R2)<0.25.
需要说明的是,本公开中的法兰结构为上法兰50。It should be noted that the flange structure in the present disclosure is the upper flange 50 .
如图8所示,各宽过流区域处的距离R1均相等,以构成参考第一参考圆;各窄过流区域处的距离R3均相等,以构成参考第二参考圆;各宽过流区域和窄过流区域处的距离R2均相等,以构成参考第三参考圆。As shown in Figure 8, the distances R1 at each wide overcurrent area are equal to form the first reference circle; the distances R3 at each narrow overcurrent area are equal to form the second reference circle; The distance R2 at both the area and the narrow overcurrent area is equal to form a reference third reference circle.
如图1至图3所示,泵体组件还包括转轴30、限位板和气缸套40,限位板具有限位板排气孔7011,气缸套40具有气缸套排气孔4012,转轴30依次穿过法兰结构、限位板和气缸套40,气缸套排气孔4012、限位板排气孔7011和法兰结构的消音通道连通。在本实施例中,限位板为上限位板70。As shown in FIGS. 1 to 3 , the pump body assembly further includes a rotating shaft 30 , a limit plate and a cylinder liner 40 , the limit plate has a limit plate exhaust hole 7011 , the cylinder liner 40 has a cylinder liner exhaust hole 4012 , and the rotating shaft 30 Passing through the flange structure, the limiting plate and the cylinder liner 40 in sequence, the exhaust hole 4012 of the cylinder liner, the exhaust hole 7011 of the limiting plate and the muffler channel of the flange structure are communicated. In this embodiment, the limiting plate is the upper limiting plate 70 .
当然,若设计的泵体组件是下排气结构时,法兰结构可以为下法兰,限位板可以为下限位板。Of course, if the designed pump body assembly is the lower exhaust structure, the flange structure can be the lower flange, and the limit plate can be the lower limit plate.
具体地,气体依次流经气缸套排气孔4012、限位板排气孔7011进入到法兰结构的消音通道,在消音通道内经过多次节流膨胀以达到降噪消音的效果,然后经过法兰排气孔5011排出。Specifically, the gas flows through the exhaust hole 4012 of the cylinder liner and the exhaust hole 7011 of the limit plate in turn to enter the muffler channel of the flange structure, and undergoes multiple throttling and expansion in the muffler channel to achieve the effect of noise reduction and noise reduction, and then passes through the muffler channel. Flange exhaust hole 5011 is exhausted.
限位板排气孔7011与法兰结构的法兰排气孔5011在法兰结构的周向上间隔设置。图4和图5中,限位板排气孔7011与法兰结构的法兰排气孔5011错开,可以使得由限位板排气孔7011进入的高压气体不会直接由法兰排气孔5011排走,而是在消音通道内部流动一定的距离后,在消音通道内经过多次节流膨胀以达到降噪消音的效果,然后经过法兰排气孔5011排出。The limit plate exhaust hole 7011 and the flange exhaust hole 5011 of the flange structure are arranged at intervals in the circumferential direction of the flange structure. In Figs. 4 and 5, the limit plate exhaust hole 7011 is staggered from the flange exhaust hole 5011 of the flange structure, so that the high-pressure gas entering through the limit plate exhaust hole 7011 will not directly pass through the flange exhaust hole. 5011 is exhausted, but after flowing for a certain distance inside the muffler channel, it undergoes multiple throttling and expansion in the muffler channel to achieve the effect of noise reduction and noise reduction, and then it is discharged through the flange exhaust hole 5011.
需要说明的是,根据阻断结构5021设置的位置和角度的不同,法兰结构的消音通道具有多个不同的结构,由于阻断结构5021可以是多个不同的角度,也可以设置在消音通道的任一位置,因此不对阻断结构5021不同位置和角度的组合的具体实施方式一一列举。It should be noted that, according to the different positions and angles of the blocking structure 5021, the muffler channel of the flange structure has a number of different structures. Since the blocking structure 5021 can be at multiple different angles, it can also be arranged in the muffler channel. Therefore, the specific embodiments of the combination of different positions and angles of the blocking structure 5021 are not listed one by one.
如图1至图3所示,在本公开中气缸套排气孔4012为多个,气缸套40具有多个中间腔4013,各中间腔4013均通过对应的气缸套排气孔4012与气缸套40的容积腔连通,气缸套40还具有与各中间腔4013连通的多个气缸套连通孔4011,限位板排气孔7011为多个,多个气缸套连通孔4011与多个限位板排气孔7011一一对应设置。As shown in FIGS. 1 to 3 , in the present disclosure, there are multiple cylinder liner exhaust holes 4012 , and the cylinder liner 40 has multiple intermediate cavities 4013 , each intermediate cavity 4013 passes through the corresponding cylinder liner exhaust hole 4012 and the cylinder liner. 40 is connected to the volume cavity, the cylinder liner 40 also has a plurality of cylinder liner communication holes 4011 that communicate with each intermediate cavity 4013, a plurality of limit plate exhaust holes 7011, a plurality of cylinder liner communication holes 4011 and a plurality of limit plates The exhaust holes 7011 are arranged in a one-to-one correspondence.
具体地,在气缸套40内部设置多个气缸套排气孔4012和多个中间腔4013,多个气缸套排气孔4012可增加排气效率,多个气缸套排气孔4012将容积腔内部的气体排入到中间腔4013内部,中间腔4013具有缓冲的作用,然后中间腔4013内部的气体依次经过多个气缸套连通孔4011、多个限位板排气孔7011排入到消音通道内部。多个气缸套排气孔4012加快了气体的排出,同时多个中间腔4013具有缓冲气体的作用。Specifically, a plurality of cylinder liner exhaust holes 4012 and a plurality of intermediate cavities 4013 are arranged inside the cylinder liner 40. The multiple cylinder liner exhaust holes 4012 can increase the exhaust efficiency, and the plurality of cylinder liner exhaust holes 4012 can reduce the volume inside the cavity. The gas in the middle cavity 4013 is discharged into the middle cavity 4013, and the middle cavity 4013 has the function of buffering, and then the gas in the middle cavity 4013 is discharged into the muffler channel through the plurality of cylinder liner communication holes 4011 and the plurality of limit plate exhaust holes 7011 in turn. . The plurality of cylinder liner exhaust holes 4012 speed up the discharge of gas, while the plurality of intermediate cavities 4013 have the function of buffering gas.
在一些实施例中,至少两个限位板排气孔7011的大小不同,多个气缸套排气孔4012中的至少两个气缸套排气孔4012的大小不同,各中间腔4013彼此不连通,多个气缸套连通孔4011的至少两个气缸套连通孔4011的大小不同。In some embodiments, the size of at least two limit plate exhaust holes 7011 is different, the size of at least two cylinder liner exhaust holes 4012 in the plurality of cylinder liner exhaust holes 4012 is different, and the intermediate cavities 4013 are not communicated with each other , at least two cylinder liner communication holes 4011 of the plurality of cylinder liner communication holes 4011 have different sizes.
当然,两个中间腔4013也可以是连通的,这样可以增加气体的流动路径,具体可以根据需要进行合理的设置。Of course, the two intermediate cavities 4013 can also be communicated, which can increase the flow path of the gas, and can be set reasonably according to needs.
在图3、图4和图7所示的具体实施例中,气缸套排气孔4012为两个,且一大一小,小的气缸套排气孔4012也可以成为泄压孔。因为气缸套排气孔4012需要与限位板排气孔7011一一对应,因此两个限位板排气孔7011也是一大一小。In the specific embodiment shown in FIG. 3 , FIG. 4 and FIG. 7 , there are two cylinder liner exhaust holes 4012 , one large and one small, and the small cylinder liner exhaust hole 4012 can also be a pressure relief hole. Because the cylinder liner exhaust holes 4012 need to correspond one-to-one with the limit plate exhaust holes 7011 , the two limit plate exhaust holes 7011 are also one large and one small.
具体地,限位板排气孔7011为两个并包括孔径不同的大孔和小孔。其中,小孔与法兰排气孔5011在法兰结构的周向上角度大于160度且小于200度,同时大孔相对于小孔设置在远离法兰排气孔5011的位置,以加强降噪消音的效果。Specifically, the limit plate exhaust holes 7011 are two and include large holes and small holes with different diameters. Among them, the angle between the small hole and the flange exhaust hole 5011 in the circumferential direction of the flange structure is greater than 160 degrees and less than 200 degrees, and the large hole is arranged at a position far from the flange exhaust hole 5011 relative to the small hole to enhance noise reduction. Noise-cancelling effect.
如图4所示,限位板排气孔7011与法兰结构的法兰排气孔5011在法兰结构的周向上间隔设置。As shown in FIG. 4 , the exhaust holes 7011 of the limiting plate and the flange exhaust holes 5011 of the flange structure are arranged at intervals in the circumferential direction of the flange structure.
具体地,限位板排气孔7011和法兰排气孔5011周向上间隔设置,当气体流经限位板排气孔7011进入到消音通道内部时,气体由限位板排气孔7011流动到法兰排气孔5011处,然后经法兰排气孔5011排出。此时气体可在消音通道内部进行多次的节流膨胀,以进行降噪消音。Specifically, the limit plate exhaust hole 7011 and the flange exhaust hole 5011 are arranged at intervals in the circumferential direction. When the gas flows through the limit plate exhaust hole 7011 and enters the interior of the muffler passage, the gas flows through the limit plate exhaust hole 7011 To the flange exhaust hole 5011, and then exhaust through the flange exhaust hole 5011. At this time, the gas can be throttled and expanded many times inside the muffler channel to reduce noise and muffle.
如图1至图2所示,在本公开中,泵体组件还包括气缸10和活塞20,气缸10可转动地设置在气缸套40的容积腔内,气缸10上沿其径向开设有活塞20孔,活塞20具有滑移孔,转轴30的至少一部分穿设在滑移孔内,活塞20随转轴30转动的过程中,活塞20相对于转轴30在活塞20孔内滑动,且气缸10同步转动。As shown in FIGS. 1 to 2 , in the present disclosure, the pump body assembly further includes a cylinder 10 and a piston 20 , the cylinder 10 is rotatably arranged in the volume cavity of the cylinder liner 40 , and the cylinder 10 is provided with a piston along its radial direction. 20 hole, the piston 20 has a sliding hole, and at least a part of the rotating shaft 30 is penetrated in the sliding hole. During the rotation of the piston 20 with the rotating shaft 30, the piston 20 slides in the hole of the piston 20 relative to the rotating shaft 30, and the cylinder 10 is synchronized turn.
从以上的描述中,可以看出,本公开上述的实施例实现了如下技术效果:From the above description, it can be seen that the above-mentioned embodiments of the present disclosure achieve the following technical effects:
通过在法兰结构的一侧设置周向延伸的消音通道,以使现法兰结构具有消音功能,周向延伸的消音通道增大了气体的流动路径,有效减小了气体流动的噪音。现有技术中的转缸压缩机需要与消音器配合使用以进行降噪消音,现有的转缸压缩机的法兰结构不具有消音功能。By arranging a circumferentially extending sound-absorbing channel on one side of the flange structure, the existing flange structure has a sound-absorbing function, and the circumferentially extending sound-absorbing channel increases the flow path of the gas and effectively reduces the noise of the gas flow. The rotary cylinder compressor in the prior art needs to be used in conjunction with a muffler for noise reduction and noise reduction, and the flange structure of the existing rotary cylinder compressor does not have a noise reduction function.
具体地,泵体组件产生的高压气体流入到法兰结构的消音通道内,并沿着消音通道周向流动,流动至法兰排气孔5011处,经法兰排气孔5011排出。有效降低了气动声噪,以使法兰结构具有消音功能。Specifically, the high-pressure gas generated by the pump body assembly flows into the muffler channel of the flange structure, flows along the circumferential direction of the muffler channel, flows to the flange exhaust hole 5011 , and is discharged through the flange exhaust hole 5011 . The aerodynamic noise is effectively reduced, so that the flange structure has the function of silencing.
为了改善现有的转缸压缩机在运行过程中,法兰结构不具有消音功能的问题,可以通过在法兰结构上开设不连通的消音凹槽(阻断式,可以参考图5示出的结构)以优化法兰结构达到实现法兰结构具有消音功能,降低气动声噪。In order to improve the problem that the flange structure does not have a sound-absorbing function during the operation of the existing rotary-cylinder compressor, a disconnected sound-absorbing groove (blocking type, can refer to Fig. 5) can be opened on the flange structure. structure) to optimize the flange structure to achieve the flange structure with a noise reduction function and reduce aerodynamic noise.
具体地,当消音通道不连通时,参考图5所示的方式,消音通道的首尾之间形成阻断结构5021,以能使进入到消音通道内部的气体沿定向路径流动,可以增强降噪效果,同时阻断结构5021可增加法兰结构的刚度,提高法兰结构的稳定性。Specifically, when the muffler channel is not connected, referring to the method shown in FIG. 5 , a blocking structure 5021 is formed between the head and the tail of the muffler channel, so that the gas entering the muffler channel can flow along a directional path, which can enhance the noise reduction effect. At the same time, the blocking structure 5021 can increase the rigidity of the flange structure and improve the stability of the flange structure.
具体地,如图9至图10所示,法兰结构朝向气缸套40的一侧开设有消音凹槽5031,消音凹槽5031沿法兰结构的周向延伸且首尾不连通,以在消音凹槽5031的首尾之间形成阻断结构5021,法兰结构还包括法兰排气孔5011,法兰排气孔5011与消音凹槽5031连通且位于消音凹槽5031的一端。Specifically, as shown in FIG. 9 to FIG. 10 , the side of the flange structure facing the cylinder liner 40 is provided with a muffler groove 5031, and the muffler groove 5031 extends along the circumferential direction of the flange structure and is not connected end to end, so that the muffler groove 5031 is not connected to the end of the muffler groove A blocking structure 5021 is formed between the head and tail of the groove 5031 , and the flange structure further includes a flange exhaust hole 5011 . The flange exhaust hole 5011 communicates with the muffler groove 5031 and is located at one end of the muffler groove 5031 .
通过在法兰结构的一侧开设消音凹槽5031,以增加高压气体的流通路径,降低噪音,同时增加了法兰结构的刚度,提高了法兰结构的稳定性。通过将法兰结构与消音器一体设计,在转缸压缩机的泵体组件实际运行的过程中,进入消音凹槽内的高压气体在流经消音凹槽规划的消音路径后,能够经法兰排气孔排出,从而完成消音和排气一体化的过程。By opening a muffler groove 5031 on one side of the flange structure, the flow path of the high-pressure gas is increased, the noise is reduced, the rigidity of the flange structure is increased, and the stability of the flange structure is improved. By integrating the flange structure with the muffler, during the actual operation of the pump body assembly of the rotary compressor, the high-pressure gas entering the muffler groove can pass through the flange after flowing through the muffler path planned by the muffler groove. The exhaust hole is exhausted to complete the process of integrating muffler and exhaust.
具体地,在法兰结构的一侧开设消音凹槽5031,法兰结构上的法兰排气孔5011与消音凹槽5031连通且位于消音凹槽5031的一端。在一些实施例中,消音凹槽5031沿法兰结构的周向延伸且首尾不连通,以在消音凹槽5031的首尾之间形成阻断结构5021。气体经法兰结构进入到消音凹槽5031内部,在消音凹槽5031内设置阻断结构5021使气体在消音凹槽5031内沿一个方向流通,可增加气体在消音凹槽5031内部的流通路径,气体在流通路径内节流膨胀后从消音凹槽5031的法兰排气孔5011排出,有效减少噪音。同时阻断结构5021具有良好的支撑作用,加强了法兰结构的刚度,在泵体组件运行的过程,法兰结构更加稳定。Specifically, a muffler groove 5031 is provided on one side of the flange structure, and the flange exhaust hole 5011 on the flange structure communicates with the muffler groove 5031 and is located at one end of the muffler groove 5031 . In some embodiments, the muffler grooves 5031 extend along the circumferential direction of the flange structure and are not connected to each other, so as to form a blocking structure 5021 between the head and tail of the muffler grooves 5031 . The gas enters the muffler groove 5031 through the flange structure, and the blocking structure 5021 is arranged in the muffler groove 5031 to make the gas flow in one direction in the muffler groove 5031, which can increase the flow path of the gas in the muffler groove 5031. After the gas is throttled and expanded in the flow path, it is discharged from the flange exhaust hole 5011 of the muffler groove 5031, which effectively reduces noise. At the same time, the blocking structure 5021 has a good supporting effect, which strengthens the rigidity of the flange structure. During the operation of the pump body assembly, the flange structure is more stable.
如图9至图10所示,消音凹槽5031的侧壁具有向法兰结构的中心轴突出的筋状结构,筋状结构为多个,多个筋状结构沿消音凹槽5031的侧壁间隔设置,以使消音凹槽5031具有交替设置的宽过流区域和窄过流区域。As shown in FIG. 9 to FIG. 10 , the side wall of the muffler groove 5031 has a rib-like structure protruding toward the central axis of the flange structure, and there are multiple rib-shaped structures along the side wall of the muffler groove 5031 They are spaced so that the muffler grooves 5031 have alternately arranged wide and narrow flow regions.
具体地,通过设置在消音凹槽5031的侧壁上的多个间隔设置的筋状结构,以使消音凹槽5031内部形成具有交替设置的宽过流区域和窄过流区域。当气体流到消音凹槽5031内部时,气体经过多个间隔设置的宽过流区域和窄过流区域时进行多次节流、膨胀,以降低噪音。Specifically, through a plurality of rib-like structures disposed on the sidewall of the muffler groove 5031 at intervals, the inside of the muffler groove 5031 is formed with alternately arranged wide flow regions and narrow flow regions. When the gas flows into the muffler groove 5031, the gas undergoes multiple throttling and expansion when passing through a plurality of spaced wide flow regions and narrow flow regions to reduce noise.
在本公开中,筋状结构的个数大于1个且小于5个。多个筋状结构使消音凹槽5031形成具有交替设置的宽过流区域和窄过流区域,以增加节流、膨胀的次数,需要说明的是,节流和膨胀的次数并不是越多越好,当筋状结构的个数大于1个且小于5个具有降噪消音的功能。在本实施例中,筋状结构的个数为3个。In the present disclosure, the number of tendon-like structures is greater than one and less than five. Multiple rib-like structures make the muffler groove 5031 form a wide flow area and a narrow flow area alternately arranged to increase the number of throttling and expansion. It should be noted that the more the number of throttling and expansion, the better. Well, when the number of tendon-like structures is greater than 1 and less than 5, it has the function of noise reduction and noise reduction. In this embodiment, the number of tendon structures is three.
如图9至图10所示,各筋状结构与法兰结构的中心轴之间的距离相等。多个筋状结构以法兰结构的中心轴为中心设置在消音凹槽5031内部,且距离法兰结构的中心轴相等,以增强消音效果。当然,也不是所有的筋状结构与法兰结构的中心轴之间的距离都必须相等。不同的筋状结构与法兰结构的中心轴之间的距离可以是部分不同,也可以是全部不同的,这里就不一一进行列举了,主要是以能够实现消音功能为基础,合理设置筋状结构与法兰结构的中心轴之间的距离。As shown in FIG. 9 to FIG. 10 , the distances between each rib-like structure and the central axis of the flange structure are equal. A plurality of rib-like structures are arranged inside the muffler groove 5031 with the central axis of the flange structure as the center, and the distance from the central axis of the flange structure is equal to enhance the muffler effect. Of course, not all rib-like structures have to be at the same distance from the central axis of the flange structure. The distance between the central axis of different rib-like structures and the flange structure may be partially different or completely different, which will not be listed here. The distance between the central axis of the flange structure and the flange structure.
如图9至图10所示,阻断结构5021的厚度D1与法兰结构的侧壁厚度G1之间满足G1≤D1≤6G1。阻断结构5021的厚度D1具有加强法兰结构刚度的作用。As shown in FIGS. 9 to 10 , the thickness D1 of the blocking structure 5021 and the thickness G1 of the sidewall of the flange structure satisfy G1≤D1≤6G1. The thickness D1 of the blocking structure 5021 has the effect of enhancing the rigidity of the flange structure.
具体地,当阻断结构5021的厚度D1小于G1时,阻断结构5021的厚度D1过小会影响法兰结构的刚度,导致法兰结构易出现变形的问题。当阻断结构5021的厚度D1大于6G1时,过大的阻断结构5021影响消音凹槽5031的长度,使气体的流通路径变短,影响消音效果。Specifically, when the thickness D1 of the blocking structure 5021 is smaller than G1, if the thickness D1 of the blocking structure 5021 is too small, the rigidity of the flange structure will be affected, and the flange structure may be easily deformed. When the thickness D1 of the blocking structure 5021 is greater than 6G1, the excessively large blocking structure 5021 affects the length of the muffler groove 5031, shortens the gas flow path, and affects the muffler effect.
因此,通过合理的控制阻断结构5021的厚度D1,可以保证消音效果。在图9所示的具体实施例中阻断结构5021的厚度D1相对较小;在图11所示的具体实施例中阻断结构5021的厚度D1相对较厚。Therefore, by reasonably controlling the thickness D1 of the blocking structure 5021, the noise reduction effect can be ensured. In the specific embodiment shown in FIG. 9 , the thickness D1 of the blocking structure 5021 is relatively small; in the specific embodiment shown in FIG. 11 , the thickness D1 of the blocking structure 5021 is relatively thick.
如图9至图10所示,阻断结构5021在消音凹槽5031里具有沿法兰结构的径向延伸的第一阻断面和第二阻断面,以过法兰结构的中心轴的一条直径作为基准线,基准线在法兰结构的周向上与第一阻断面之间具有第一夹角α,基准线在法兰结构的周向上与第二阻断面之间具有第二夹角β,以使第一阻断面和第二阻断面在法兰结构的周向上的夹角为β-α。As shown in FIG. 9 to FIG. 10 , the blocking structure 5021 has a first blocking surface and a second blocking surface extending along the radial direction of the flange structure in the muffler groove 5031 so as to pass through the central axis of the flange structure. A diameter is used as a reference line, the reference line has a first included angle α between the circumferential direction of the flange structure and the first blocking surface, and the reference line has a second angle α between the circumferential direction of the flange structure and the second blocking surface. The included angle β is such that the included angle between the first blocking surface and the second blocking surface in the circumferential direction of the flange structure is β-α.
具体地,阻断结构5021的角度设置在α与β之间,阻断结构5021的角度小于α或者大于β时会影响法兰结构的密封性,具有气体泄漏的风险。Specifically, the angle of the blocking structure 5021 is set between α and β. When the angle of the blocking structure 5021 is smaller than α or larger than β, the sealing performance of the flange structure will be affected, and there is a risk of gas leakage.
需要说明的是,本公开中的法兰结构为上法兰50。It should be noted that the flange structure in the present disclosure is the upper flange 50 .
如图1至图3所示,泵体组件还包括转轴30、限位板和气缸套40,限位板具有限位板排气孔7011,气缸套40具有气缸套排气孔4012,转轴30依次穿过法兰结构、限位板和气缸套40,气缸套排气孔4012、限位板排气孔7011和法兰结构的消音凹槽5031连通。限位板为上限位板70。As shown in FIGS. 1 to 3 , the pump body assembly further includes a rotating shaft 30 , a limit plate and a cylinder liner 40 , the limit plate has a limit plate exhaust hole 7011 , the cylinder liner 40 has a cylinder liner exhaust hole 4012 , and the rotating shaft 30 Passing through the flange structure, the limit plate and the cylinder liner 40 in sequence, the exhaust hole 4012 of the cylinder liner, the exhaust hole 7011 of the limit plate and the muffler groove 5031 of the flange structure communicate with each other. The limit plate is the upper limit plate 70 .
当然,若设计的泵体组件是下排气结构时,法兰结构可以为下法兰,限位板可以为下限位板。Of course, if the designed pump body assembly is the lower exhaust structure, the flange structure can be the lower flange, and the limit plate can be the lower limit plate.
具体地,气体依次流经气缸套排气孔4012、限位板排气孔7011进入到法兰结构的消音凹槽5031,在消音凹槽5031内经过多次节流膨胀以达到降噪消音的效果,然后经过法兰排气孔5011排出。Specifically, the gas flows sequentially through the exhaust hole 4012 of the cylinder liner and the exhaust hole 7011 of the limit plate into the muffler groove 5031 of the flange structure, and is throttled and expanded for many times in the muffler groove 5031 to achieve noise reduction and noise reduction. effect, and then discharged through the flange exhaust hole 5011.
如图7、图9、图10和图11所示,限位板排气孔7011与法兰结构的法兰排气孔5011在法兰结构的周向上间隔设置。图中,限位板排气孔7011与法兰结构的法兰排气孔5011错开,可以使得由限位板排气孔7011进入的高压气体不会直接由法兰排气孔5011排走,而是在消音凹槽5031内部流动一定的距离后,在消音凹槽5031内经过多次节流膨胀以达到降噪消音的效果,然后经过法兰排气孔5011排出。As shown in FIG. 7 , FIG. 9 , FIG. 10 and FIG. 11 , the exhaust holes 7011 of the limiting plate and the flange exhaust holes 5011 of the flange structure are arranged at intervals in the circumferential direction of the flange structure. In the figure, the limit plate exhaust hole 7011 is staggered from the flange exhaust hole 5011 of the flange structure, so that the high-pressure gas entering through the limit plate exhaust hole 7011 will not be directly exhausted through the flange exhaust hole 5011, Instead, after flowing for a certain distance inside the muffler groove 5031 , the muffler groove 5031 undergoes multiple throttling and expansion to achieve the effect of noise reduction and muffler, and then it is discharged through the flange exhaust hole 5011 .
需要说明的是,如图9至图10所示的具体实施例中,根据阻断结构5021设置的位置和角度的不同,法兰结构的消音凹槽5031具有多个不同的结构,由于阻断结构5021可以是多个不同的角度,也可以设置在消音凹槽5031的任一位置,因此不对阻断结构5021不同位置和角度的组合的具体实施方式一一列举。下面,根据限位板排气孔7011和法兰排气孔5011的分布位置不同提供不同的实施方式。It should be noted that, in the specific embodiments shown in FIG. 9 to FIG. 10 , according to the different positions and angles of the blocking structure 5021 , the muffler groove 5031 of the flange structure has a number of different structures. The structure 5021 can be at a plurality of different angles, and can also be arranged at any position of the muffler groove 5031, so the specific implementations of the combination of different positions and angles of the blocking structure 5021 are not listed one by one. In the following, different embodiments are provided according to the different distribution positions of the vent holes 7011 of the limiting plate and the vent holes 5011 of the flange.
如图9所示的具体实施方式中,限位板排气孔7011和法兰排气孔5011分别位于法兰结构的消音凹槽5031的两端并位于阻断结构5021的两侧。In the specific embodiment shown in FIG. 9 , the limiting plate exhaust hole 7011 and the flange exhaust hole 5011 are respectively located at both ends of the muffler groove 5031 of the flange structure and on both sides of the blocking structure 5021 .
具体地,限位板排气孔7011和法兰排气孔5011分别位于阻断结构5021的两侧,当气体流经限位板排气孔7011进入到消音凹槽5031内部时,气体由消音凹槽5031的一端 流动到消音凹槽5031的另一端,然后经法兰排气孔5011排出。此时气体可在消音凹槽5031内部进行多次的节流膨胀,以进行降噪消音。Specifically, the limit plate exhaust hole 7011 and the flange exhaust hole 5011 are located on both sides of the blocking structure 5021, respectively. When the gas flows through the limit plate exhaust hole 7011 and enters the inside of the muffler groove 5031, the gas is removed by the muffler. One end of the groove 5031 flows to the other end of the muffler groove 5031, and then is discharged through the flange exhaust hole 5011. At this time, the gas can be throttled and expanded multiple times in the muffler groove 5031 to perform noise reduction and muffling.
如图10所示的具体实施方式中,限位板排气孔7011和法兰排气孔5011分别位于法兰结构的消音凹槽5031的两端并位于阻断结构5021的同一侧。此时气体需要在消音凹槽5031内经过节流膨胀后经过法兰排气孔5011流出。相比于图9中的方式,图10所提供的流通路径的长度要短一些。In the specific embodiment shown in FIG. 10 , the limiting plate exhaust hole 7011 and the flange exhaust hole 5011 are respectively located at both ends of the muffler groove 5031 of the flange structure and on the same side of the blocking structure 5021 . At this time, the gas needs to be throttled and expanded in the muffler groove 5031 and then flow out through the flange exhaust hole 5011 . Compared to the approach in FIG. 9 , the length of the flow path provided in FIG. 10 is shorter.
如图7和图9所示,限位板排气孔7011为多个,且至少两个限位板排气孔7011的大小不同。多个限位板排气孔7011间隔设置。限位板排气孔7011可以设置多个,以将气体排入到消音凹槽5031内部,为避免过于集中将多个限位板排气孔7011间隔设置。As shown in FIG. 7 and FIG. 9 , there are multiple exhaust holes 7011 in the limiting plate, and at least two exhaust holes 7011 in the limiting plate have different sizes. A plurality of limit plate exhaust holes 7011 are arranged at intervals. A plurality of limit plate exhaust holes 7011 may be provided to discharge gas into the sound-absorbing groove 5031 . To avoid excessive concentration, the plurality of limit plate exhaust holes 7011 are arranged at intervals.
如图7和图9所示,限位板排气孔7011为两个并包括孔径不同的大孔和小孔。其中,小孔与法兰排气孔5011在法兰结构的周向上角度大于30度且小于200度,同时大孔相对于小孔靠近法兰结构的阻断结构5021,以加强降噪消音的效果。As shown in FIG. 7 and FIG. 9 , there are two exhaust holes 7011 in the limiting plate and include large holes and small holes with different diameters. Among them, the angle between the small hole and the flange exhaust hole 5011 in the circumferential direction of the flange structure is greater than 30 degrees and less than 200 degrees, and the large hole is close to the blocking structure 5021 of the flange structure relative to the small hole to enhance noise reduction and noise reduction. Effect.
如图1至图3所示,在本公开中气缸套排气孔4012为多个,气缸套40具有多个中间腔4013,各中间腔4013均通过对应的气缸套排气孔4012与气缸套40的容积腔连通,气缸套40还具有与各中间腔4013连通的多个气缸套连通孔4011,多个气缸套连通孔4011与多个限位板排气孔7011一一对应设置。As shown in FIGS. 1 to 3 , in the present disclosure, there are multiple cylinder liner exhaust holes 4012 , and the cylinder liner 40 has multiple intermediate cavities 4013 , each intermediate cavity 4013 passes through the corresponding cylinder liner exhaust hole 4012 and the cylinder liner. The cylinder liner 40 also has a plurality of cylinder liner communication holes 4011 that communicate with each intermediate cavity 4013, and the plurality of cylinder liner communication holes 4011 are provided in a one-to-one correspondence with a plurality of limit plate exhaust holes 7011.
具体地,在气缸套40内部设置多个气缸套排气孔4012和多个中间腔4013,多个气缸套排气孔4012可增加排气效率,多个气缸套排气孔4012将容积腔内部的气体排入到中间腔4013内部,中间腔4013具有缓冲的作用,然后中间腔4013内部的气体依次经过多个气缸套连通孔4011、多个限位板排气孔7011排入到消音凹槽5031内部。多个气缸套排气孔4012加快了气体的排出,同时多个中间腔4013具有缓冲气体的作用。Specifically, a plurality of cylinder liner exhaust holes 4012 and a plurality of intermediate cavities 4013 are arranged inside the cylinder liner 40. The multiple cylinder liner exhaust holes 4012 can increase the exhaust efficiency, and the plurality of cylinder liner exhaust holes 4012 can reduce the volume inside the cavity. The gas inside the middle cavity 4013 is discharged into the middle cavity 4013, and the middle cavity 4013 has the function of buffering, and then the gas inside the middle cavity 4013 is discharged into the muffler groove through the plurality of cylinder liner communication holes 4011 and the plurality of limit plate exhaust holes 7011 in turn. Inside 5031. The plurality of cylinder liner exhaust holes 4012 speed up the discharge of gas, while the plurality of intermediate cavities 4013 have the function of buffering gas.
在一些实施例中,多个气缸套排气孔4012中的至少两个气缸套排气孔4012的大小不同。各中间腔4013彼此不连通。多个气缸套连通孔4011的至少两个气缸套连通孔4011的大小不同。In some embodiments, at least two cylinder liner exhaust holes 4012 of the plurality of cylinder liner exhaust holes 4012 are of different sizes. The intermediate cavities 4013 do not communicate with each other. At least two cylinder liner communication holes 4011 of the plurality of cylinder liner communication holes 4011 have different sizes.
在图3所示的具体实施例中,气缸套排气孔4012为两个,且一大一小,小的气缸套排气孔4012也可以成为泄压孔。因为气缸套连通孔4011需要与限位板排气孔7011一一对应,因此两个气缸套连通孔4011也是一大一小。In the specific embodiment shown in FIG. 3 , there are two cylinder liner exhaust holes 4012 , one large and one small, and the small cylinder liner exhaust holes 4012 can also be used as pressure relief holes. Because the cylinder liner communication holes 4011 need to be in one-to-one correspondence with the limit plate exhaust holes 7011, the two cylinder liner communication holes 4011 are also one large and one small.
当然,两个中间腔4013也可以是连通的,这样可以增加气体的流动路径,具体可以根据需要进行合理的设置。Of course, the two intermediate cavities 4013 can also be communicated, which can increase the flow path of the gas, and can be set reasonably according to needs.
如图2所示,在本公开中,泵体组件还包括气缸和活塞20,气缸可转动地设置在气缸套40的容积腔内,气缸上沿其径向开设有活塞孔,活塞20具有滑移孔,转轴30的至少一部分穿设在滑移孔内,活塞20随转轴30转动的过程中,活塞20相对于转轴30在活塞孔内滑动,且气缸同步转动。As shown in FIG. 2 , in the present disclosure, the pump body assembly further includes a cylinder and a piston 20 , the cylinder is rotatably arranged in the volume cavity of the cylinder liner 40 , a piston hole is opened on the cylinder along its radial direction, and the piston 20 has a sliding At least a part of the rotating shaft 30 passes through the sliding hole.
