Introduction to the troubleshooting method of solenoid valve

And power elimination method analysis does not action power cable connection good power supply voltage changes are not allowed within the range, coil short circuit or burn down the power line adjustment voltage in the normal range through the valve through the valve to replace the fluid failure coil: fluid pressure or working pressure difference does not meet the fluid viscosity or temperature does not meet the valve spool and miscellaneous An item of dirt, a front filter or a guide valve, which is too high in frequency or can not be cut off for the replacement of the internal fluid of the cleaning product due to adjustment pressure or work pressure difference or replacement. The filter valve must be installed to clean the filter or guide valve hole in time to model or replace the valve valve: fluid sticky When the temperature is not consistent, when the temperature of the fluid is not conformed, due to the spring seat or living deformation, defect or adhesion of stolen goods, the information of "defect or deformation" is closed, the balance hole or hole is blocked, and the working frequency is too high or living. Correct product replacement and replacement of suitable products and gaskets or replacement springs, cleaning, grinding or updating, re cleaning successive models or changing new product leaks: pipe joint loose pipe connection seal damage, fastening bolt or replacement seal pipe leakage serious: fluid temperature is not consistent, guide valve and main valve impurities or lack of main valve Sag, pad sag or deformation, deformation or improper assembly of spring, life expectancy pilot valve and main valve, use working frequency too high, adjust or replace fluid temperature. If there is, cleaning or polishing repair or replacement of gasket replacement spring model or replacement of product reappointment voltage fluctuation through noisy fasteners, no pressure difference is not suitable for the fluid viscosity that does not conform to the armature surface impurities tightening to the adjustment or replacement pressure or the range of working pressure range. Pressure or work product replace normal range adjustment. If there is strength, in most cases solenoid valve coil is open or resistance increases, coil current can not be opened normally.
