When the plunger pump of the fracturing truck runs, the suction and discharge sealing combination valve can continuously impact and collide with a valve seat structure on the valve box body in the uninterrupted opening and closing process, wherein most impact force is borne by valve rubber; meanwhile, as the working medium of the pump set is mortar water, sediment particles can erode the collision surface of the valve rubber to form rubber body surface pitting, and as the working time is accumulated, the rubber body surface pitting can develop into sheet-shaped, block-shaped damage and falling, finally, sealing failure is caused, and a required pressure state cannot be established in the valve cavity.
The description of the failure mechanism of the valve seal can be known from the description: after the sealing failure, the valve body and the valve box body are in metal collision movement, a strong impact signal is generated, abnormal change can be caused to the pressure state in the valve cavity, so that the liquid discharge pressure is insufficient, the condition of the pressure change in the valve cavity cannot be directly monitored, but the valve body fault and the severity thereof can be indirectly described by the condition of the vibration change of the surface of the valve box body, namely, the valve box body surface vibration time domain signal peak value is larger, so that the fault cylinder body can be accurately judged through the vibration data change monitored by the vibration sensor 5, and guidance is provided for maintenance of maintenance personnel.

Secondly, as the abrasion gap between the plunger and the copper sleeve is increased in an abrasion state after long-term heavy load use, the same axial thrust causes different speeds of the pull rod impacting the crankshaft, and the impact load is changed; meanwhile, the lubrication state of the bearing bush is changed due to the change of the fit clearance, the surface of the plunger body is in black carbonization caused by thermal expansion, and the lubrication condition of the bearing bush can be indirectly reflected by monitoring the surface temperature of the plunger body, so that the plunger fault can be monitored and early warned through the use of the temperature sensor 6.
