| Abstract: | In the early period, most of engineering trains purchased by Guangzhou Metro were working with piston air compressor. The malfunction rate of piston air compressor is higher than the screw compressor. Valve working condition quality is one of the key problems of the advantage of air compressor. Study of valve fault mechanism and fault diagnosis method deeply, it is of great practical significance. |
