Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor upper shell leakage detection device. 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 draws in low-temperature, low-pressure refrigerant gas from the intake pipe, compresses it through the motor-driven piston, and discharges high-temperature, high-pressure refrigerant gas into the exhaust pipe, powering the refrigeration cycle.

[0003] Existing compressor casings often experience leaks during the production process. This is typically done through immersion, which requires completely immersing the compressor casing in water to detect bubbles. This method is time-consuming and inefficient. Some high-precision airtightness testers require a long preheating and calibration period before testing, which also increases the time cost of testing. For large-scale compressor manufacturers, low testing efficiency can impact production schedules. Therefore, a compressor casing leak detection device is needed to address this issue. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that leakage detection is usually carried out by immersion method, which requires the compressor upper casing to be completely immersed in water to observe whether bubbles are generated. This method takes a long time to detect and has low efficiency. A leakage detection device for the compressor upper casing is proposed.

[0005] The cam is fixedly mounted on a support frame, and the cam is secured to a position 400 meters high and is accessible via a plurality of channel slots, wherein the cam is secured on a plurality of channels and is accessible via a plurality of channel slots.

[0006] Preferably, support legs are fixedly connected to the bottom of the working plate near the four corners, and the bottoms of the support legs are all trapezoidal.

[0007] Preferably, one end of the screw rod passes through the inner wall of the other end of the movable cavity and is rotatably connected to its bearing, and a drive motor is fixedly connected to one end of the working plate near the center, and the output end of the drive motor is fixedly connected to one end of the screw rod.

[0008] Preferably, a limiting rod is passed through and slidably connected to the surface of the limiting plate near both ends, and both ends of the limiting rod are fixedly connected to the inner walls of both ends of the limiting sliding hole.

[0009] Preferably, the connecting pipe is a telescopic hose.

[0010] Preferably, a control panel is fixedly mounted on the surface of the working plate near one end, and the control panel is electrically connected to the driving motor and the smoke pump.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] In the utility model, the shell to be inspected is placed on the working plate, and the screw is driven to rotate by the driving motor, and the rotation of the screw drives the connecting plate to move. The movement of the connecting plate can drive the movable plate to move through the limit plate and the connecting block. The movement of the movable plate can enable the first silicone pad and the second silicone pad to clamp the two ends of the shell, which can have the effect of sealing the holes at both ends of the shell of different sizes. At this time, smoke can be injected into the interior of the shell to perform a leak detection on the shell, thereby achieving the effect of improving the detection efficiency and saving water resources.
