| Abstract: | A method is presented for diagnosing the faults of a plunger displacement pump by means of the vibration signals from the surfaces of its moving parts. The monitoring position of every moving part is determined according to the structural and motion characteristics of the plunger displacement pump. The sources and influence factors of the vibration excitations are analyzed. The characteristic frequencies of vibration exciting sources were calculated according to theoretical and empirical formulas. The frequency spectrum characteristics of the vibration exciting sources were determined. The example in field shows that the method is feasible and effective. |
