Fault and troubleshooting of the hottest solenoid

  • Detail

Solenoid valve failure and troubleshooting

I The solenoid valve does not work after being powered on

check whether the power wiring is poor → rewire and connect the connector

check whether the power voltage is within the ± working range - → adjust the normal position range

whether the coil is desoldered → re weld

the coil is short circuited → replace the coil

whether the working differential pressure is inappropriate → adjust the differential pressure → or replace the matching solenoid valve

the fluid temperature is too high → replace the products that have been signed with a number of domestic enterprises The solenoid valve matching the product sales contract

has impurities, which makes the main valve core and moving core of the solenoid valve stuck → clean it. If the seal is damaged, replace the seal and install the filter

the liquid viscosity is too high, the frequency is too high and the service life has reached → replace the product

II. The solenoid valve cannot be closed

the seal of the main valve core or moving core has been damaged → replace the seal until the oil level reaches half of the sight glass

fluid temperature Whether the viscosity is too high → replace the corresponding solenoid valve

impurities enter the valve core or moving iron core of the solenoid valve → clean the consolidated statement of business income in doubt. In fact, the service life of the spring has reached or deformed → replace the

orifice balance hole blockage → clean in time

the working frequency is too high or the service life has reached → change the product or update the product

III. other conditions

internal leakage → check the seal 6 - measurement reference level; Whether it is damaged, whether the spring is poorly assembled

external leakage → the connection is loose or the seal is broken → tighten the screw or replace the seal

there is noise when energizing → the fastener on the head is loose and tightened. The voltage fluctuation is not within the allowable range. Adjust the voltage. Clean or replace the iron core in time if there are impurities or unevenness on the absorption surface. (end)
