Abstract:The main forms of support failures were collected and analyzed, and the main reason for failures was leakage of high pressure liquid. According to the high-frequency character of leak signals, the detection theory was put forward, that is the failures and its positions could be found by detecting the high-frequency leak signals. And then the signal receiver was drawn out by using the method of probability theory. Based on the theory, the detector of leak failures was developed. The practice of the detector shows that it can adapt to the complex conditions and works well, its accuracy to find failures is higher than direct method.
