Solenoid valves also have conditions when they are working. These conditions often cause production and work delays, and even serious economic losses. As China's demand for such products continues to increase, more attention should be paid to related problems. For solenoid valves, what are the solutions for not working after the solenoid valve is energized?
1. Check if the power supply wiring is bad:
Rewiring and connector connection Check whether the power supply voltage is within ± working range, adjust whether the coil in the normal position range is unwelded, re-weld the coil short circuit, replace the coil working pressure difference is not suitable, the whole pressure difference, or replace the proportional solenoid valve If the fluid temperature is too high, replace the commensurate solenoid valve with impurities to cause the main valve core and the moving iron core of the solenoid valve to be stuck and cleaned . If there is seal damage, replace the seal and install the filter.
2 , the solenoid valve can not be closed
The seal of the main spool or the iron core has been damaged. The fluid temperature and viscosity of the seal are replaced. The solenoid valve of the replacement port has impurities entering the solenoid valve spool or moving iron core for cleaning. The spring life has reached or Deformation, you need to replace, the orifice balance hole is blocked, cleaned in time, the working frequency is too high or the life has arrived, re-elect the product or update the product .
3. Other situations:
Internal leakage: check the seal for damage and the spring is not properly assembled
External leakage: the connection is loose or the seal is broken; there is noise when the screw or replacement seal is energized; the solid part on the head is loose and tightened. The voltage fluctuation is not within the allowable range and the voltage is adjusted. The iron core suction surface is dirty or uneven, and it is cleaned or replaced in time.
The use of a class of products is unlikely to be smooth, and as the use of the product continues to deepen, the probability of problems that the product may be exposed increases. For the solenoid valve, it already has a relatively good development foundation, and the emergence of related problems has already had a better solution. For the merchant, it is very important to provide consumers with better product protection. There should be better plans and preparations for problems that may arise with the product.
The above solenoid valve technology is provided by the three precision valves
