Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automation basic component used to control fluid. It belongs to the actuator and is not limited to hydraulic and pneumatic. Used in industrial control systems to adjust the direction, flow, speed, and other parameters of the medium.
If the solenoid valve coil is burned out, the wiring of the solenoid valve can be removed and measured with a multimeter. If it is open, the solenoid valve coil is burned out. The reason is that the coil is damp, causing poor insulation and magnetic leakage, causing excessive current in the coil and burning. Therefore, it is necessary to prevent rainwater from entering the solenoid valve. In addition, if the spring is too hard, the reaction force is too large, the number of turns of the coil is too small, and the suction force is not enough, the coil can also be burnt.
The solenoid valve does not switch on and off: The matching gap between the solenoid valve spool sleeve and the valve core is very small. Generally, it is a single-piece assembly. When mechanical impurities are brought in or there is too little lubricating oil, it is easy to get stuck. The treatment method can be made by inserting a steel wire from the small hole in the head to make it rebound. The fundamental solution is to remove the solenoid valve, take out the valve core and valve core sleeve, and clean it with CCI4 to make the valve core move flexibly in the valve sleeve. When disassembling, pay attention to the assembly sequence of the components and the position of the external wiring, so that the reassembly and wiring are correct, and also check whether the oil spray hole of the lubricator is blocked and whether the lubricating oil is sufficient.
