Research on Reciprocating Machinery Fault Diagnosis and Testing Method
Based on characteristics and operating principle of reciprocating machinery, we presented fault diagnosis and data testing method of reciprocating machinery, which features the testing based on crank phase signal, cylinder pressure, temperature, vibration and ultrasonic signal, developed a embedded data acquisition system, and described system composition and module functions. We also realized a CAN bus-based data transmission and communication mode, introduced the slave computer software working flow of the testing system, and developed the data processing and fault analysis software with LABVIEW. The practical tests show that crank phase signal-based data testing can meet requirements on fault diagnosis and data acquisition of reciprocating machinery.
