Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to an inlet regulating device of a compressor. Background Art

[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It inhales low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it through the operation of the motor to drive the piston, and then discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. During the use of the compressor, in order to control the working state and flow output, it is necessary to adjust the inlet pressure of the compressor, that is, to adjust the opening of the inlet. The opening of the inlet refers to the degree of opening and closing of the inlet, which determines the size of the intake volume. When the inlet opening increases, the intake volume also increases accordingly. Conversely, when the inlet opening decreases, the intake volume also decreases accordingly.

[0003] It is common that after a long period of use, some fine impurities carried by the wind are easy to adhere to the inlet of the compressor. After a long period of accumulation, the valve plate that controls the opening may be restricted in movement during rotation due to the influence of impurities, making the valve plate prone to jamming during rotation, affecting the smoothness of the valve plate adjustment and delaying the adjustment of the compressor inlet opening.

[0004] Therefore, it is necessary to provide a new inlet regulating device for a compressor to solve the above technical problems. Utility Model Content

A circular groove 8 is opened on one side of the valve plate 7, and a circular rod 1 9 is rotatably installed on the valve plate 7. A motor 2 10 is arranged on one side of the valve plate 7, and the output shaft of the motor 2 10 is fixedly connected to one end of the circular rod 1 9. An adapter plate 11 is fixedly sleeved on the end of the circular rod 19 away from the motor 2 10, and two fixed blocks 12 are fixedly installed on one side of the adapter plate 11, and the same circular rod 2 13 is rotatably installed between the two fixed blocks 12, and a motor 3 14 is arranged on one side of the corresponding fixed block 12, and the output shaft of the motor 3 14 is fixedly connected to one end of the circular rod 2 13, and a set block 15 is fixedly sleeved on the circular rod 2 13, and a scraper 16 is fixedly installed on the bottom of the set block 15, and the bottom of the scraper 16 contacts the inner wall of the air inlet 2.

[0024] In order to provide space for the two threaded rods 6 to be inserted into the rotating rod 3 and ensure that the two threaded rods 6 fix the rotating rod 3, a circular through hole is opened on the rotating rod 3, and the ends of the two threaded rods 6 that are close to each other extend into the circular through hole. Two pointing blocks 2 are fixedly installed on the rotating rod 3, and the two pointing blocks 2 respectively point to the two ends of the circular through hole, so as to facilitate the judgment of the direction of the circular through hole.

[0025] In order to ensure the stability of the installation of the three motors, a support seat 1 is fixedly installed on the top of the air inlet 2, and the inner wall of one side of the support seat 1 is fixedly connected to the base of the motor 1 4, a support seat 2 is fixedly installed on one side of the valve plate 7, and the support seat 2 is fixedly connected to the base of the motor 2 10, and a support seat 3 is fixedly installed on one side of the corresponding fixed block 12, and the support seat 3 is fixedly connected to the base of the motor 3 14.

[0028] The working principle of the inlet regulating device of the compressor provided by the utility model is as follows:

[0029] During the use of the vane compressor 1, by starting the motor 4, the motor 4 will drive the rotating rod 3 fixedly connected thereto, and the rotating rod 3 will then drive the valve plate 7 through the connecting block 5. During the rotation of the valve plate 7, the opening of the air inlet 2 will be adjusted, and the air intake volume will be controlled accordingly, thereby regulating the inlet pressure of the vane compressor 1. The distribution directions of the two pointing blocks 18 are adapted to the valve plate 7. By observing the two pointing blocks 18, it is convenient to determine the position of the valve plate 7. In some special cases, if the motor 4 cannot be put into use normally, it is necessary to manually adjust the valve plate 7. During operation, the two threaded rods 6 are rotated successively, and the ends of the two threaded rods 6 that are close to each other will gradually move out of the rotating rod 3. At this time, the fixation of the rotating rod 3 by the two threaded rods 6 will be released, and then the rotating rod 3 can be rotated by the handle 17 to adjust the valve plate 7.

[0030] In the initial state, the scraper 16 is in a vertical state and is located on one side of the adapter plate 11. After a long period of use, in order to prevent the subsequent adjustment of the valve plate 7 from being stuck and sluggish, the inner wall of the air inlet 2 within the movable range of the valve plate 7 needs to be cleaned. During operation, the motor three 14 is started first. The motor three 14 will drive the circular rod two 13 fixedly connected thereto to rotate. The circular rod two 13 drives the set block 15, and the set block 15 drives the scraper 16 to rotate clockwise, and the scraper 16 originally distributed horizontally in the longitudinal direction is adjusted to be distributed horizontally in the transverse direction, so that the scraper 16 contacts the bottom inner wall of the air inlet 2. Then the motor three 14 is automatically closed, and then the motor two 10 is started again. The motor two 10 will drive the circular rod two 13 fixedly connected thereto to rotate. Rod 19, the circular rod 9 then drives the scraper 16 to rotate through the adapter plate 11. During the rotation of the scraper 16, it will gradually contact different positions on the inner wall of the air inlet 2, so that all impurities within the movable range of the scraper 16 in the air inlet 2 are scraped off, thereby ensuring the smooth movement of the valve plate 7. After the cleaning is completed, the motor 3 14 is started again, and the output shaft of the motor 3 14 rotates in the opposite direction to retract the scraper 16, thereby ensuring that the subsequent adjustment of the valve plate 7 is not affected by the scraper 16. In addition, through the control of the motor 4, the position of the scraper 16 can be changed, and the scraper 16 can be moved to the left, so that the left movable area of ​​the valve plate 7 is cleaned by the scraper 16, thereby improving the flexibility of equipment use.

[0031] Compared with the related art, the compressor inlet regulating device provided by the utility model has the following beneficial effects:

[0032] In the utility model, the valve plate 7 can be driven to rotate by the drive of the motor 1 4, thereby completing the adjustment of the opening of the air inlet 2, so as to adjust the inlet pressure of the vane compressor 1. Rotating the two threaded rods 6 can release the fixation between the motor 1 4 and the rotating rod 3, so as to facilitate manual adjustment of the opening of the valve plate 7 under special circumstances. With the cooperation of the motor 2 10 and the motor 3 14, the position of the scraper 16 can be adjusted so that the scraper 16 contacts the inner wall of the air inlet 2, and then the scraper 16 is used to clean part of the inner wall of the air inlet 2, so as to clean the impurities within the movable range of the valve plate 7, thereby improving the smoothness of the movement of the valve plate 7 and reducing the jamming when the valve plate 7 is adjusted.
