Leak detection system and method for air compressor

Abstract

The invention discloses a leak detection system and method for an air compressor. The air compressor comprises an oil-gas separator, an after-cooler and an electromagnetic valve used for exhausting, wherein the oil-gas separator is provided with an oil inlet, and the after-cooler is provided with an air outlet. The leak detection system comprises a testing module, wherein the testing module comprises an air inlet and two air delivery openings, the air inlet is connected with a compressed air source, and the air delivery openings are connected with the air inlet and the air outlet respectively; the testing module further comprises an adjustment device and two switching devices and further comprises pressure detectors which are arranged at the position of the oil inlet and the position of the air outlet, and the pressure detectors are used for detecting the air pressure of the oil inlet and the air pressure of the air outlet respectively and outputting all actually-measured pressure values; the testing module further comprises a control circuit, and closing and opening of the electromagnetic valve are controlled by opening or closing the control circuit respectively. By the adoption of the leak detection system and method for the air compressor, automatic, quantitative and traceable leak detection of the air compressor can be achieved.

Description

technical field [0001] The invention relates to the field of air compressors, in particular to a leak detection system and method for an air compressor. Background technique [0002] At present, the leak detection of air compressors usually uses several air pipes to inject air into the air compressor, and then the inspectors use the leak detection liquid to rule out whether there are leakage points in the air compressor pipelines one by one. There are many defects in such traditional detection methods. First of all, relying entirely on the visual inspection of the inspectors for leak detection, it is possible that the leak detection may be missed or some connection parts cannot be detected, or even a very small leak point cannot be observed, which will cause oil and air leakage of the air compressor and reduce the reliability; secondly , the detection results of this detection method cannot be quantified, cannot be traced, and cannot provide a basis for measuring the assemb...
