Description

Technical Field

[0002] In the related art, it is necessary to test the performance parameters of a compressor to determine whether the specific performance of the compressor meets the standards.

[0003] In the prior art, for example, a compressor test bench disclosed in the patent publication number CN209979254U includes a motor, a gas-liquid separation barrel, a pump and a test bench base. The pump and the gas-liquid separation barrel are connected and respectively arranged at the left front end and the right front end of the test bench base. A bracket is arranged at the rear end of the test bench base, and a motor mounting plate for mounting the motor is arranged on the bracket. A central bracket for connecting the compressor is arranged at the front end of the motor. A compressor test base is arranged in front of the central bracket on the test bench base. A moving mechanism capable of moving relative to the compressor test base is arranged under the motor mounting plate. During the alignment process of the motor shaft and the compressor shaft, the motor shaft can be adjusted by moving. When replacing the compressor to be tested, the disassembly and installation of the compressor will not be difficult due to the existence of the central bracket and the coupling with tight fit, which can greatly improve the detection progress of the compressor, thereby improving the production efficiency of the main engine factory.

[0004] Although the above patent can solve the problem of difficult disassembly and installation of the compressor, the foot positions of each model are different, resulting in the inability to install compressors of various models. Moreover, when the compressor operates under extreme conditions, the operating conditions of the gas and liquid inside the compressor cannot be detected. Therefore, the above problems need to be improved. Content of the Utility Model

[0005] The purpose of the utility model is to provide a testing device for a compressor, which has the effect of being able to detect the operating conditions of gas and liquid.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A testing device for a compressor includes a test frame. A connecting rod is fixedly connected to the outside of the test frame. A connecting shaft is fixedly connected to the inside of the connecting rod. A first gear is fixedly installed at the top of the connecting shaft. A second gear is meshed with the outside of the first gear. A motor is arranged outside the second gear. The second gear is fixedly connected to the output end of the motor. A bearing seat is fixedly installed at the bottom of the test frame. A bearing is fixedly installed inside the bearing seat. A rotating shaft is rotatably connected to the inside of the bearing. A wheel is arranged at the bottom of the rotating shaft. Slide rails are fixedly connected to both sides inside the test frame. A mounting block is slidably connected to the inside of the slide rail. An excitation block is arranged inside the mounting block. A positioning bracket is lapped on the top of the excitation block. A bolt is threadedly connected to the inside of the positioning bracket.

[0007] By adopting the above technical solution, the mounting blocks are slid inside the test stand through the slide rails. According to the positions of the bottom feet of the compressor, the four mounting blocks are respectively moved below the four feet. Through the displacement of the four mounting blocks, the device can install compressors of different models. The positioning bracket is lapped on the top of the excitation block. The positioning bracket wraps the feet of the compressor, and the positioning bracket is fixed by bolts. Thus, the compressor can be fixed above the test stand, and the fixing effect is good. When testing the compressor, start the motor, so that the motor drives the second gear to rotate. The first gear and the second gear are meshed, and then the first gear drives the connecting rod, the connecting shaft and the test stand to rotate. The compressor inside the test stand moves in a circular motion around the second gear. By the high-speed swing of the compressor, the operation conditions of the gas and liquid inside the compressor can be detected. When the test stand rotates, the wheels will rotate inside the bearings through the rotating shafts. The wheels support the other side of the test stand and maintain the effect of rotating support.

By the shaking of the compressor, the operation conditions of the gas and liquid inside the compressor under the condition of shaking can be detected.

[0012] A further setting of the present utility model is that: L-shaped plates are fixedly connected to both sides of the vibration machine, and screws are threadedly connected to the inside of the L-shaped plates.

[0013] By adopting the above technical solution, the L-shaped plates are on the left and right sides of the vibration machine. Thread the screws into the inside of the L-shaped plates, and then extend the screws into the inside of the mounting blocks. Thus, the vibration machine can be fixed inside the mounting blocks. By fixing the vibration machine, the phenomenon that the internal components are damaged during excitation can be prevented.

[0014] A further setting of the present utility model is that both sides of the inner wall of the mounting block are fixedly connected with linear tracks, and a slide bar is slidably connected inside the linear tracks.

[0018] A further setting of the present utility model is that an anti-slip layer is fixedly connected to the outside of the wheel, and anti-slip patterns are provided on the outside of the anti-slip layer.

[0019] By adopting the above technical solution, the anti-slip layer and the anti-slip patterns increase the friction during the rotation of the wheel, preventing slipping.

[0020] A further setting of the present utility model is that the number of the linear tracks is two, and the two linear tracks are symmetrical to each other.

[0021] By adopting the above technical solution, the two linear tracks are on both sides of the mounting block, and the two slide bars are slidably connected inside the two linear tracks.

[0022] A further setting of the present utility model is that a steel shell is fixedly connected to the outside of the motor, and heat dissipation holes are provided inside the steel shell.

[0023] By adopting the above technical solution, the steel shell protects the motor, and the heat dissipation holes dissipate heat from the motor.

[0024] A further setting of the present utility model is that a grille is fixedly connected to the top of the steel shell.
