[0001] The utility model relates to the technical field of compressor detection equipment, in particular to a compressor air tightness testing device. Background Art

[0002] The 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 suction pipe, compresses it through the piston driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle. During the production process, it is particularly important to control the quality of the compressor and conduct compressor air tightness testing.

[0003] The patent with publication number CN211978231U and the name of a compressor air tightness detection device discloses a compressor air tightness detection device, which includes a cleaning mechanism and a detection mechanism.

The base is closed on all sides, and the base is filled with a cleaning liquid. The detection mechanism includes a base, a bracket installed in the base, a water guide component installed on the base, and a lighting component installed on the base. The base is filled with a detection agent. The utility model has the effect of cleaning off the oil stains on the compressor before the air tightness test. This patented technology has shortcomings in actual application. The detection method of the equipment is to put the compressor into water for air tightness detection, which is not only time-consuming and labor-intensive and wastes water resources, but also the compressor may be damaged after being soaked in water, which affects subsequent use.
