0543 0545 Straight-through industrial solenoid valve coil

The fit clearance between the spool sleeve and the valve core of solenoid valve is very small (less than 0.008mm), which is generally assembled in one piece. When there are mechanical impurities or too little lubricating oil, it is easy to get stuck. The treatment method can be used to stab the steel wire from the small hole in the head to make it bounce back. 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. During disassembly, attention should be paid to the assembly sequence and external wiring position of each component, so as to reassemble and wire correctly. Also, check whether the oil spray hole of the oil mist sprayer is blocked and whether the lubricating oil is sufficient.

If the solenoid valve coil is burnt out, the wiring of the solenoid valve can be removed and measured with a multimeter. If the circuit is open, the solenoid valve coil is burnt out. The reason is that the coil is damp, which leads to poor insulation and magnetic leakage, resulting in excessive current in the coil and burning, so it is necessary to prevent rainwater from entering the solenoid valve. In addition, 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, which can also cause the coil to burn. In case of emergency treatment, the manual button on the coil can be turned from the "0" position in normal operation to the "1" position to open the valve.

For some customers' requirements on the switching time of solenoid valves, some solenoid valves need to be energized for a long time, but ordinary solenoid valves can't meet the requirements of long-term energization. At this time, we can choose the long-term energized solenoid valve of Weidun VTON in the United States, or the dual-coil self-holding solenoid valve, which can be continuously energized without time limit and will not burn when energized for 365 days a year.
