| Abstract: | The work process of the gas valves of type 2D12 reciprocating compressors was analyzed, the local sound signal at the compression section was extracted when both the admission valve and the exhaust valve were closed based on the work characteristics of the gas valves. The time frequency analysis chart of the normal gas valves and faulty gas valves were given by using the generalized bilinear time frequency method to diagnose the faults of the gas valves. |
