The daily maintenance of the solenoid valve is indispensable for its stable operation. Inspect the exterior regularly for damage, corrosion, or foreign objects. For example, if the solenoid valve is used in the chemical environment, the shell may crack due to chemical erosion, and if it is not found and repaired in time, it may cause damage to the internal components. Cleaning work is very important, for the air inlet and outlet, to remove dust, impurities, to prevent it from entering the valve affecting the spool action. In the factory workshop with large dust, it can be regularly purged with compressed air. Check the electrical connection to ensure that the connection is strong, not loose or oxidized, because loose electrical connection may cause the solenoid valve to work abnormally or even burn the coil, such as the solenoid valve on the frequent vibration equipment should be checked. Test the operation of the solenoid valve, observe whether the spool is opened and closed smoothly and in place, by manual operation or input test signal. In the food and beverage industry, if the solenoid valve is not working properly, it may affect the product ratio and packaging accuracy. In addition, pay attention to the condition of seals, such as aging, deformation should be replaced in time to ensure good sealing, to prevent media leakage caused by security risks and waste of resources.
