应用本发明的技术方案，由于在工作腔包括吸气腔和压缩腔，其中，工作腔在进行排气过程中，排气通道处会保留一部分高压气体，当滑片即将扫过排气通道时，排气通道处存储的高压气体会与工作腔的吸气腔相连通，这部分气体由于压力高于吸气压力，工作腔内就会出现过膨胀的现象，工作腔内的气流方向指向吸气腔，造成此时的滑片吸气侧所受的合力也就指向滑片的远离排气通道的一端，在这两个合力的作用下滑片就会受到一个转动力矩，在这个力矩的作用下滑片会产生翻转，进而会碰到第一法兰、第二法兰的精加工面，并产生撞击。由于这个撞击改变了滑片的受力情况，也会导致滑片撞击气缸，从而产生负面的压缩机振动和噪音。通过在第一法兰上设置排气通道，在第二法兰上设置气流平衡部，在气流平衡部处会产生一个与第一法兰的排气通道处相反的转动力矩来平衡第一法兰排气所产生的力矩，这样使得滑片的转动力矩被平衡掉后，滑片的受力将处于平衡状态，从而避免了滑片发生倾覆的情况，从而保证压缩机的可靠运行，有效地减小压缩机的振动和噪音。Applying the technical solution of the present invention, since the working chamber includes a suction chamber and a compression chamber, during the exhaust process of the working chamber, a part of the high-pressure gas will remain at the exhaust channel. The high-pressure gas stored in the exhaust channel will communicate with the suction chamber of the working chamber. Because the pressure of this part of the gas is higher than the suction pressure, the phenomenon of over-expansion in the working chamber will occur, and the direction of the air flow in the working chamber is directed to the suction chamber. The air cavity causes the resultant force on the suction side of the sliding blade at this time to point to the end of the sliding blade away from the exhaust channel. Under the effect of these two forces, the sliding blade will receive a rotating moment. The sliding plate will be flipped, which will hit the finished surface of the first flange and the second flange, and cause an impact. Because this impact changes the force of the sliding blade, it will also cause the sliding blade to hit the cylinder, which will cause negative compressor vibration and noise. By providing an exhaust passage on the first flange and an air flow balancing portion on the second flange, a rotational torque opposite to the exhaust passage of the first flange is generated at the air flow balancing portion to balance the first method. The torque generated by the blue exhaust gas, so that after the rotating moment of the sliding blade is balanced, the force of the sliding blade will be in a balanced state, thereby avoiding the overturning of the sliding blade, thereby ensuring the reliable operation of the compressor and effectively Reduce compressor vibration and noise.

结合图2至图9所示，根据本发明的实施例，提供了一种泵体组件。With reference to FIGS. 2 to 9, a pump body assembly is provided according to an embodiment of the present invention.
具体地，泵体组件包括第一法兰10、第二法兰20、气缸组件30、转轴40和滑片50。气缸组件30分别与第一法兰10和第二法兰20相连接。气缸组件30位于第一法兰10和第二法兰20之间。转轴40依次穿设于第一法兰10、气缸组件30和第二法兰20内。转轴40上开设有滑片槽41。滑片50设置于滑片槽41内。滑片50与气缸组件30相配合以在气缸组件30内形成工作腔。其中，第一法兰10上开设有与工作腔相连通的排气通道11，第二法兰20上开设有气流平衡部。当工作腔处于排气状态时，气缸组件30内的气流在气流平衡部处形成力矩为F的力施加于滑片50的远离排气通道11的一端，以使滑片50在工作腔工作的过程中不发生倾斜。Specifically, the pump body assembly includes a first flange 10, a second flange 20, a cylinder assembly 30, a rotating shaft 40, and a sliding plate 50. The cylinder assembly 30 is connected to the first flange 10 and the second flange 20, respectively. The cylinder assembly 30 is located between the first flange 10 and the second flange 20. The rotating shaft 40 passes through the first flange 10, the cylinder assembly 30 and the second flange 20 in this order. The rotating shaft 40 is provided with a sliding plate groove 41. The sliding plate 50 is disposed in the sliding plate groove 41. The sliding plate 50 cooperates with the cylinder assembly 30 to form a working cavity in the cylinder assembly 30. The first flange 10 is provided with an exhaust passage 11 communicating with the working cavity, and the second flange 20 is provided with an air flow balancing portion. When the working chamber is in the exhaust state, the airflow in the cylinder assembly 30 forms a force of moment F at the airflow balancing portion and is applied to the end of the sliding plate 50 away from the exhaust passage 11 to make the sliding plate 50 work in the working chamber. No tilt occurs during the process.
在本实施中，由于在工作腔包括吸气腔和压缩腔，其中，工作腔在进行排气过程中，排气通道处会保留一部分高压气体，当滑片即将扫过排气通道时，排气通道处存储的高压气体会与工作腔的吸气腔相连通，这部分气体由于压力高于吸气压力，工作腔内就会出现过膨胀的现象，工作腔内的气流方向指向吸气腔，造成此时的滑片吸气侧所受的合力也就指向滑片的远离排气通道的一端，在这两个合力的作用下滑片就会受到一个转动力矩，在这个力矩的作用下滑片会产生翻转，进而会碰到第一法兰、第二法兰的精加工面，并产生撞击。由于这个撞击改变了滑片的受力情况，也会导致滑片撞击气缸，从而产生负面的压缩机振动和噪音。通过在第一法兰上设置排气通道，在第二法兰上设置气流平衡部，在气流平衡部处会产生一个与第一法兰的排气通道处相反的转动力矩来平衡第一法兰排气所产生的力矩，这样使得滑片的转动力矩被平衡掉后，滑片的受力将处于平衡状态，从而避免了滑片发生倾覆的情况，从而保证压缩机的可靠运行，有效地减小压缩机的振动和噪音。In this implementation, since the working chamber includes a suction chamber and a compression chamber, during the exhaust process of the working chamber, a part of the high-pressure gas will remain at the exhaust passage. When the sliding blade is about to sweep through the exhaust passage, the exhaust The high-pressure gas stored in the air channel will communicate with the suction chamber of the working chamber. Because the pressure of this part of the gas is higher than the suction pressure, the phenomenon of over-expansion in the working chamber will occur, and the direction of the air flow in the working chamber will point to the suction chamber. As a result, the resultant force on the suction side of the sliding blade at this time points to the end of the sliding blade away from the exhaust channel. Under the effect of these two forces, the sliding blade will receive a rotating moment, and the sliding blade will act on this moment. There will be overturning, which will hit the finished surface of the first flange and the second flange, and cause an impact. Because this impact changes the force of the sliding blade, it will also cause the sliding blade to hit the cylinder, which will cause negative compressor vibration and noise. By providing an exhaust passage on the first flange and an air flow balancing portion on the second flange, a rotational torque opposite to the exhaust passage of the first flange is generated at the air flow balancing portion to balance the first method. The torque generated by the blue exhaust gas, so that after the rotating moment of the sliding blade is balanced, the force of the sliding blade will be in a balanced state, thereby avoiding the overturning of the sliding blade, thereby ensuring the reliable operation of the compressor and effectively Reduce compressor vibration and noise.
其中，第二法兰20的与排气通道11相对的位置处开设有气流平衡部。这样设置能够进一步提高压缩机的稳定性和可靠性。The second flange 20 is provided with an air flow balancing portion at a position opposite to the exhaust passage 11. This arrangement can further improve the stability and reliability of the compressor.
优选地，气流平衡部为凹槽21，凹槽21开设于第二法兰20的朝向排气通道11一侧的表面上。这样设置能够使得工作腔在排气过程中，工作腔内的气流能在凹槽21处产生施加与滑片的力矩，以使滑片始终处于平衡位置不发生倾斜。其中，工作腔包括压缩腔和吸气腔。工作腔一边进行吸气一边进行压缩作业。第一法兰可以是上法兰，第二法兰可以是下法兰。当然，第一法兰也可以是下法兰，第二法兰也可以是上法兰。Preferably, the airflow balancing portion is a groove 21, and the groove 21 is formed on a surface of the second flange 20 facing the exhaust passage 11. Such a setting can make the air current in the working cavity generate a torque applied to the sliding plate at the groove 21 during the exhausting process of the working cavity, so that the sliding plate is always in a balanced position without tilting. The working chamber includes a compression chamber and a suction chamber. The working chamber performs compression while inhaling. The first flange may be an upper flange, and the second flange may be a lower flange. Of course, the first flange can also be a lower flange, and the second flange can also be an upper flange.
为了能够使得在凹槽21处产生的力矩能够与排气通道处产生的力矩刚好抵消掉，将排气通道11在第二法兰20上的投影设置成与凹槽21相重合。值得注意的是，此处的“重合”指的是排气通道11的投影形状与凹槽的形状、大小完全相同。In order to enable the moment generated at the groove 21 to be exactly offset with the moment generated at the exhaust passage, the projection of the exhaust passage 11 on the second flange 20 is set to coincide with the groove 21. It is worth noting that "overlap" here means that the projected shape of the exhaust channel 11 is exactly the same as the shape and size of the groove.
进一步地，气流平衡部为排气通孔，排气通孔贯通地开设于第二法兰20上，排气通孔与排气通道11相对地设置。这样设置同样能够起到平衡滑片的作用。进一步地，排气通孔的横截面的型线与排气通道的横截面的型线相同。Further, the air flow balancing portion is an exhaust through hole, and the exhaust through hole is opened through the second flange 20, and the exhaust through hole is provided opposite to the exhaust passage 11. This arrangement can also play the role of balancing the sliding plate. Further, the profile of the cross section of the exhaust passage is the same as the profile of the cross section of the exhaust passage.
其中，部分的转轴40的外周面上设置有环形凸出部42，环形凸出部42位于气缸组件30内，滑片槽41开设于环形凸出部42上，滑片槽41沿环形凸出部42的径向方向延伸设置。滑片槽41为多个，多个滑片槽41沿环形凸出部42的周向间隔地设置，滑片50为多个，多个滑片50与多个滑片槽41一一对应地设置，多个滑片50将气缸组件30的内部分隔成多个独立的工作腔。这样设置能够提高压缩机的性能。Among them, an annular protruding portion 42 is provided on the outer peripheral surface of a part of the rotating shaft 40. The annular protruding portion 42 is located in the cylinder assembly 30. The sliding blade groove 41 is opened on the annular protruding portion 42. The sliding blade groove 41 protrudes along the annular shape. The portion 42 is provided so as to extend in the radial direction. There are a plurality of sliding blade grooves 41, and the plurality of sliding blade grooves 41 are arranged at intervals along the circumferential direction of the annular protruding portion 42. It is provided that a plurality of sliding fins 50 divide the interior of the cylinder assembly 30 into a plurality of independent working chambers. This arrangement can improve the performance of the compressor.
进一步地，气缸组件30包括气缸31、滚动件32和轴承套33。滚动件32设置于气缸31内并套设于转轴40上，滑片槽41与滚动件32的内壁面相配合，以将滚动件32的内壁面与转轴40之间分隔成工作腔。轴承套33套设于滚动件32上，至少部分的轴承套33位于气缸31的内壁面与滚动件32的外周面之间，滚动件32与轴承套33之间设置有滚动体34。Further, the cylinder assembly 30 includes a cylinder 31, a rolling member 32, and a bearing sleeve 33. The rolling member 32 is disposed in the cylinder 31 and sleeved on the rotating shaft 40. The sliding plate groove 41 cooperates with the inner wall surface of the rolling member 32 to separate the inner wall surface of the rolling member 32 and the rotating shaft 40 into a working cavity. The bearing sleeve 33 is sleeved on the rolling member 32. At least a part of the bearing sleeve 33 is located between the inner wall surface of the cylinder 31 and the outer peripheral surface of the rolling member 32. A rolling body 34 is provided between the rolling member 32 and the bearing sleeve 33.

具体地，在排气通道相对的下法兰上设置气流平衡部，能够平衡上法兰排气口处的压力波动，减小压力对滑片的扰动，从而减弱滑片对上、下法兰端面和轴承的撞击。有效地改善了滑片压缩机的振动和噪音水平。在本实施例中，排气通孔的横截面的型线与排气通道11的横截面的型线相同，其中，排气通道11的长宽比小于等于4。优选地，排气通道11的横截面为菱形结构。Specifically, an air flow balancing portion is provided on the lower flange opposite to the exhaust channel, which can balance the pressure fluctuation at the exhaust port of the upper flange, reduce the disturbance of the pressure on the sliding plate, and thus weaken the sliding plate to the upper and lower flange Impact of end face and bearing.

Preferably, the cross section of the exhaust passage 11 is a rhombus structure.
压缩机运转时，在电机的带动下转轴随之旋转，滑片在离心力的作用下从滑片槽伸出，并与滚动件的内圈的内壁面接触。随着压缩机的平稳运行，滑片在滑片槽中开始做往复运动，滑片的头部与内壁面接触，并带动内圈进行旋转。其中，滑片为3个，3个滑片与滚动件的内圈把整个月牙腔分为3个独立的腔室，这3个腔室周期性的扩大、缩小，从而实现压缩机的吸气、排气。压缩机运动过程中，滑片与滑片槽形成一个封闭的空间，称之为滑片背压腔，该滑片背压腔也有三个，并且随着压缩机的运转，背压腔周期性的放大和缩小。在泵体组件下部装有泵油浸在压缩机底部油池内，转轴旋转带动油泵旋转，油泵为一种容积式泵，油泵的作用除了给泵体各摩擦副提供润滑油外，还为滑片背压腔提供具有一定压力的油压。When the compressor is running, the rotating shaft is rotated by the motor, and the sliding blade is protruded from the sliding blade groove under the centrifugal force, and contacts the inner wall surface of the inner ring of the rolling element. With the smooth operation of the compressor, the sliding blade starts to make reciprocating motion in the sliding blade groove, the head of the sliding blade is in contact with the inner wall surface, and the inner ring is driven to rotate. Among them, there are 3 slides, and the inner circle of the 3 slides and the rolling element divides the entire crescent cavity into 3 independent chambers. These 3 chambers are periodically expanded and contracted to realize the suction of the compressor. ,exhaust. During the movement of the compressor, the sliding vane and the sliding vane groove form a closed space, which is called the sliding vane back pressure cavity. There are also three sliding vane back pressure cavities. With the operation of the compressor, the back pressure cavity periodically Zoom in and out. The lower part of the pump body is equipped with pump oil immersed in the oil pool at the bottom of the compressor. The rotation of the shaft drives the oil pump to rotate. The oil pump is a positive displacement pump. The role of the oil pump is to provide lubricating oil to the friction pairs of the pump body. The back pressure chamber provides oil pressure with a certain pressure.
如图4至图6所示，为压缩机排气时滑片位置，此时压缩机处于排气，排气口处气体为排气压力Pd。此时气流的方向是有气缸内部指向法兰外部，气流方向向滑片上部排气。由于 排气口处气流的速度较大，所以根据动、静能转换原理，排气口的压力较低，而滑片下部的压力为高压，滑片排气侧面受到的合力方向向上。As shown in FIG. 4 to FIG. 6, it is the sliding vane position when the compressor is exhausted. At this time, the compressor is in the exhaust, and the gas at the exhaust port is the exhaust pressure Pd. At this time, the direction of the air flow is that the inside of the cylinder points to the outside of the flange, and the direction of the air flow exhausts to the upper part of the sliding blade. Because the velocity of the airflow at the exhaust port is large, according to the principle of dynamic and static energy conversion, the pressure at the exhaust port is low, while the pressure at the lower part of the sliding plate is high, the direction of the resultant force on the exhaust side of the sliding plate is upward.
如图7和图8所示，为压缩机排气过后滑片位置，此时滑片将要扫过排气通道的排气口，因为压缩排气后，排气口处会保留一部分高压气体，但是滑片即将扫所排气口时，排气口处储存的高压气体也与吸气腔连通，这部分气体由于压力大大高于吸气压力，就会出现过膨胀的现象，气流方向指向吸气腔，滑片吸气侧所受的合力也就指向滑片下部，其受力示意图如图1所示。如此，在这两个合力(F1、F2)的作用下滑片就会受到一个转动力矩，在这个力矩的作用下滑片会产生翻转，进而碰到上、下法兰精加工面，产生撞击。由于这个撞击改变了滑片的受力，也会导致滑片撞击气缸，从而产生负面的压缩机振动和噪音。As shown in Figures 7 and 8, this is the position of the sliding vane after the compressor exhausts. At this time, the sliding vane will sweep through the exhaust port of the exhaust channel, because after the exhaust is compressed, a part of high-pressure gas will remain at the exhaust port. However, when the sliding blade is about to sweep the exhaust port, the high-pressure gas stored at the exhaust port is also in communication with the suction chamber. Because the pressure of this part of the gas is much higher than the suction pressure, the phenomenon of over-expansion will occur. The resultant force on the air cavity and the suction side of the slider is also directed towards the lower part of the slider. The schematic diagram of the force is shown in Figure 1. In this way, under the action of these two combined forces (F1, F2), the sliding plate will receive a rotating moment, and the sliding plate will be flipped under the action of this moment, and then hit the upper and lower flange finishing surfaces to produce an impact. Because this impact changes the force of the sliding blade, it will also cause the sliding blade to hit the cylinder, which will cause negative compressor vibration and noise.
如图9所示，在下法兰上开设一凹槽，此凹槽的位置与上法兰对称布置，但不打通，根据受力的关系分析会产生一个与上法兰排气口相反的转动力矩来平衡上法兰排气所产生的力矩。这样一来滑片的转动力矩被平衡掉后，滑片的受力将更加均衡，从而避免了滑片的倾覆，从而保证压缩机的可靠运行，减小压缩机的振动和噪音。As shown in Figure 9, a groove is opened in the lower flange. The position of this groove is symmetrically arranged with the upper flange, but it is not open. According to the analysis of the relationship between the forces, a rotation opposite to the exhaust port of the upper flange will be generated. Torque to balance the torque generated by the exhaust of the upper flange. In this way, after the rotating moment of the sliding blade is balanced, the force of the sliding blade will be more balanced, thereby avoiding the overturning of the sliding blade, thereby ensuring the reliable operation of the compressor and reducing the vibration and noise of the compressor.
