Troubleshooting relief valve

In practical use, in order to maximize the effectiveness of pilot relief, protection and control vehicle identification systemaccurate and timely diagnosis, excluding pilot type relief valve failure is the key part.
Pressure limiting instability: pilot pressure relief valve limiting instability, manifested as low or high pressure hydraulic systems, hydraulic actuators action unable or tubing, pump, valve burst. Cause of this failure reasons: improper pressure adjustment; pilot valve spool spring bend or soften; oil too dirty or poor oil flow. Appropriate measures are excluded: readjust; calibration padded or replacement; replacement, cleaning. Pilot pressure relief valve limiting the gradual onset unstable failure, pilot-type relief valve failure.
Pilot type relief valve failure, will cause the injection molding machine inoperable. According to the phenomenon, analysis of the reasons are: the pilot valve spool spring break; Yin Nicon blockage; pilot valve port seal bad; the main valve stuck and so on. Corresponding exclusion measures are: replacement or broken at the flat washers to emergency use; cleaning dredge; grinding or the oil circuit breaker to emergency use; grinding, cleaning.
For all aspects of small tanker spill analysis. Enhance the use of small tankers. Small tanker used very widely, so it is necessary to understand the work of the various parts of a small tanker. Small tanker spill analysis works well for your relief valve failure. Are constantly deepening the internal structure of a small gas station management system. Small tanker analytical works.
