Solenoid valve troubleshooting
1, it is recommended to use the unit to assign someone responsible for, use and maintenance. 2, 1-2 times a year regular maintenance is the solenoid valve reliable work and the best way to live longer. Solenoid valve within the following four kinds of situations, is to prevent the normal operation of the solenoid valve and shorten the life of reason. 2.1, the medium changes during use 2.2, take over the rust 2.3, air compressor oil oxidation, produce carbon tar and other debris, mixed with pipe 2.4 Dust and other impurities in the pipeline 3, solenoid valve installed or long Time to stop re-put into operation, access to the media should be tested for several attempts to work properly before the official use of 4, the steam valve to stop running for a long time after the operation should be drained condensate after a few moves to try to work Normal back into operation. 5, before maintenance, must cut off the power, remove the media pressure. 6, solenoid valve coil assembly should not be opened 7, open the solenoid valve cleaning, you can use kerosene, trichlorethylene and other solutions, but should pay attention to the rubber may Will be swollen, so to replace the rubber parts. 8, open the cleaning, the parts should be put in order to restore the installation. 9, my company has wearing parts, if necessary, please press instructions when ordering instructions. 10, demolition order, wearing parts and other matters do not understand, please check with our company or local offices. Failure analysis and troubleshooting methods Failure analysis and treatment methods Power does not operate Poor power connection Poor power supply voltage variation is not within the allowable range Short circuit or burn out the coil Connect the power line to adjust the voltage within the normal range Change the coil when the valve is opened Valve can not pass the fluid pressure or Working pressure does not meet the fluid viscosity or temperature does not meet the valve core and moving around the core mixed with impurities, impurities, pre-filter valve or pilot valve blockage Working frequency is too high or life expectancy Adjust the pressure or working pressure difference or replacement Suitable Products Replacement Suitable Products Internal cleaning, filter valve must be installed in front of the valve Clean the filter or pilot valve hole in time Re-select the product model or replacement of new products Fluid can not be cut off when the valve is closed Fluid viscosity does not meet the fluid temperature Does not meet the spring deformation or Expiration of Service Life Valve Seat Defective or Adhesive Stolen Gasket Exits `Defective or Deformed Balance Hole or Throttle Clogged Operating Frequency Too High or End of Life Replacement Suitable Product Replacement Suitable Product Plus Gasket or Replacement Spring Cleaning , Grind or update, re-assembly and prompt cleaning product model selection or change New Product Leakage Pipe Connection Loose Pipe Connection Damaged Outer Seals Tighten Bolts or Take Over Threads Replace Leaks in Seals Serious Fluids Temperature Nonconformities Dirty or Defective Leading Pilot Seat and Main Seat Leading Pins and Main Valve Seals Leaking or Deformed Poor spring assembly, deformation, or expiration of working life Working frequency too high Adjusting fluid temperature or replacement Cleaning or grinding if any Repair or replacement Replacing the seal Replacing the spring Replacing the product model or replacing a new product Too much noise when energized Fastener loose Voltage fluctuation is not within the allowable range Fluid pressure or working pressure is not suitable Fluid viscosity does not match Armature suction surface with impurities Tighten adjusted to the normal range Adjust the pressure or differential pressure or replace the product Replace the appropriate product promptly cleaned
