During the operation of the equipment, vibration and friction are inevitable, and when abnormality occurs in the equipment, vibration increase, temperature increase and change of working performance occur. Statistically, more than 60% of mechanical failures are reflected by vibrations. In recent years, statistical analysis on the faults of the reciprocating pump also shows that the faults of the power end in all the faults of the reciprocating pump account for about 39 percent, mainly including the pulling or the fracture of a crankshaft, the locking of a crosshead, the overproof clearance of a crankshaft bearing bush and a crosshead pin bush, and the like; the hydraulic end failure accounts for about 61%, mainly including the failure of the suction valve and the discharge valve, the cracking of the pump head and the like. The fault point of the reciprocating pump is found in time, and maintenance measures are taken, so that the serious loss can be avoided.
