Description

一种旋摆驱动刮片式压缩机及其使用方法Swing-driven wiper-type compressor and method of using the same 技术领域technical field

At present, there are various principles and structures used by compressors, such as piston type, turbine type, centrifugal type, screw type, scroll type, wiper type, etc. Among them, the wiper type compressor has a simple structure and manufacturing process, and a small volume. , low cost, easy maintenance and other advantages, so it is preferentially used in low-power occasions where space is small, cost control and easy maintenance are required. The wiper of the wiper type compressor usually uses the pressure of the return spring or the centrifugal force generated by the rotation of the rotor to maintain the seal between the wiper and the cylinder wall. This method balances the friction between the wiper and the chute. It becomes complicated, and the operating speed of the compressor changes greatly, especially when the speed is low, the compressor will run unstable due to the radial vibration of the scraper or the friction with the chute, which will affect the lubrication and noise of the compressor. Control and longevity are also very unfavorable. Based on the above reasons, it is necessary to further improve the running stability, reduce the volume, reduce the running noise, improve the lubrication conditions and prolong the running life on the basis of retaining the inherent advantages of the wiper type compressor.

参阅图1-4，本发明的实施例在使用中通过转子3上的驱动轴31与原动机相连，当转子3被驱动作顺时针旋转时，与转子3联动的刮片4也随同在缸体2内旋转，由于端盖5中的旋转销轴导槽521和摆动销轴导槽521分别对贯穿刮片4的旋转销轴411和摆动销轴412两端的运动约束，刮片4在随转子作旋转运动的同时也绕旋转销轴411作摆动运动，从而在转子、缸壁和刮片之间形成多个空间容积呈周期性变化的隔舱，每个隔舱室在转过进气口6时其容积由小增大而吸入气体，当隔舱在转过排气口7时其容积由大变小从而压缩气体并排出气体到排气口7。在压缩机运转的过程中，主要靠端盖5中的旋转销轴导槽521和摆动旋转销轴导槽522对刮片4所连接的旋转销轴411和摆动销轴412的约束实现吸气-排气隔舱的容积变化，因而刮片与气缸壁之间的摩擦力也比较稳定，有利于压缩机的润滑和降低噪音，从而提高使用寿命。1-4, the embodiment of the present invention is connected to the prime mover through the drive shaft 31 on the rotor 3 in use. When the rotor 3 is driven to rotate clockwise, the scraper 4 linked with the rotor 3 is also in the cylinder. The body 2 rotates. Since the rotating pin guide groove 521 and the swing pin guide groove 521 in the end cover 5 constrain the movement of the two ends of the rotating pin 411 and the swing pin 412 passing through the scraper 4 respectively, the scraper 4 will move along with the When the rotor rotates, it also swings around the rotating pin shaft 411, thereby forming a plurality of compartments with periodic changes in space volume between the rotor, the cylinder wall and the scraper. Each compartment is rotating through the air inlet. At 6, its volume increases from small to inhale gas, and when the compartment passes through the exhaust port 7, its volume changes from large to small to compress the gas and discharge the gas to the exhaust port 7. During the operation of the compressor, suction is mainly achieved by the restriction of the rotating pin shaft 411 and the swinging pin shaft 412 connected to the scraper 4 by the rotating pin shaft guide groove 521 and the swinging rotating pin shaft guide groove 522 in the end cover 5 . - The volume of the exhaust compartment changes, so the friction between the scraper and the cylinder wall is relatively stable, which is beneficial to the lubrication of the compressor and reduce noise, thereby increasing the service life.

  5. 根据权利要求3或4所述的一种旋摆驱动刮片式压缩机的使用方法，其特征在于，具体如下：A method of using a swing-driven wiper compressor according to claim 3 or 4, characterized in that, the details are as follows:
    在使用中通过转子(3)上的驱动轴(31)与原动机相连，当转子(3)被驱动作顺时针旋转时，与转子(3)联动的刮片(4)也随同在缸体(2)内旋转， 由于端盖(5)中的旋转销轴导槽(521)和摆动销轴导槽(521)分别对贯穿刮片(4)的旋转销轴(411)和摆动销轴(412)两端的运动约束，刮片(4)在随转子作旋转运动的同时也绕旋转销轴(411)作摆动运动，从而在转子、缸壁和刮片之间形成多个空间容积呈周期性变化的隔舱，每个隔舱室在转过进气口(6)时其容积由小增大而吸入气体，当隔舱在转过排气口(7)时其容积由大变小从而压缩气体并排出气体到排气口(7)。In use, it is connected to the prime mover through the drive shaft (31) on the rotor (3). When the rotor (3) is driven to rotate clockwise, the scraper (4) linked with the rotor (3) is also in the cylinder block. (2) Internal rotation, since the rotating pin shaft guide groove (521) and the swing pin shaft guide groove (521) in the end cover (5) are respectively opposite to the rotating pin shaft (411) and the swing pin shaft passing through the scraper (4) (412) The movement constraints at both ends, the scraper (4) rotates with the rotor and also swings around the rotating pin (411), thereby forming a plurality of space volumes between the rotor, the cylinder wall and the scraper. Periodically changing compartments, the volume of each compartment increases from small to inhale gas when it turns over the air inlet (6), and its volume changes from large to small when it turns over the exhaust port (7) Thereby the gas is compressed and discharged to the exhaust port (7).
