Abstract:
1. A compressor leakage detector, comprising: a water tank, whose top has an opening with a cover; an elevator platform disposed in the water tank and driven by a driving mechanism to rise and drop vertically, the elevator platform having the ability to hold a plurality of compressors to test and to sink into the water in the tank; a control panel disposed by the water tank and having an operating panel; wherein the operating panel has a human-machine interface and at least one indicator and at least one pressure gauge for each of the compressors, the control panel has a programmable controller connected with the human-machine interface, and the human-machine interface is used to set parameters of the number of compressors to test, a testing pressure, and a testing time; and a pressure testing unit disposed in the control panel and using an intake pipe to connect a plurality of branch pipes that connect to the compressors in the water tank; wherein each of the branch pipes connects in series at least one intake electromagnetic (EM) valve and at least one exhaust EM valve, and a pressure sensor is interposed between the intake EM valve and the compressor; wherein the compressors on the elevator platform connect to the corresponding branch pipes and sink into the water in the tank, the compressors are pressurized to the testing pressure after the cover covers the opening, the at least one pressure gauge shows the internal pressure of each of the corresponding compressors, the indicators show test results after the testing time is over, and the exhaust EM valve releases the pressure of each of the compressors.
