Pilot relief valve fault diagnosis

    In practice, in order to maximize the pilot relief valve efficiency, protection control system, accurate and timely diagnosis, troubleshooting pilot relief valve is a key part. Pilot-type relief valve failure will result in injection molding machine can not move. According to the phenomenon, the analysis of the reasons: the pilot valve spool spring break; Yin Ni hole plug; pilot valve port seal bad; the main spool stuck and so on. The corresponding precautions are as follows: replace or flatten the pad at the breakage for emergency use; clean and clear; grind or break the oil path for emergency use; grinding and cleaning. Pressure-limiting instability: Pilot-based pressure relief valve relief valve instability, manifested as low or high pressure hydraulic system, hydraulic actuator weakness or tubing, pump body, body burst. The reasons for this failure are: improper pressure adjustment; pilot valve spool spring bent or softened; oil is too dirty or poor fluid flow. The corresponding exclusion measures are: readjustment, correction, matting or replacement; replacement, cleaning. Pilot-type relief valve pressure limiting instability is a progressive failure, pilot-relief valve failure is a sudden failure, after the exclusion of the fault, the injection molding machine system should be limited by the pressure on the pilot-operated relief valve control Press again to adjust.
