Solenoid valves are composed of a solenoid coil and a magnetic core, a valve body containing one or several holes. When the coil is energised or de-energised, the operation of the core will cause the fluid to pass through the valve body or be cut off for the purpose of changing the direction of the fluid. The electromagnetic part of the solenoid valve consists of a fixed core, a moving core, a coil and other components; the valve body part consists of a slide core, a slide sleeve, a spring base and other components. The solenoid coil is mounted directly on the valve body, and the valve body is enclosed in a sealed tube, forming a simple, compact combination. The solenoid valves we commonly use in production are two-position three-way, two-position four-way, two-position five-way, etc. Here is the meaning of two-position: for the solenoid valve is charged and de-energised, for the valve under control is open and closed.
1, the solenoid valve terminal is loose or wire off, the solenoid valve shall not power, can tighten the wire.
2, the solenoid valve coil burned, you can remove the wiring of the solenoid valve, measured with a multimeter, if the open circuit, the solenoid valve coil burned. The reason is that the coil is damp, causing bad insulation and leakage of magnetism, resulting in excessive current in the coil and burned, so to prevent rain into 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, the suction force is not enough can also make the coil burned. Emergency treatment, the manual button on the coil from the normal work of the "0" bit to "1" bit, so that the valve open.
3, solenoid valve stuck: solenoid valve slide sleeve and spool with a very small clearance (less than 0.008mm), are generally a single assembly, when there are mechanical impurities brought in or too little lubricant, it is easy to jam. Treatment available steel wire from the head of the small hole stabbed into, so that it pops back. The fundamental solution is to remove the solenoid valve, remove the spool and spool sleeve, clean with CCI4, making the spool flexible in the valve sleeve action. Disassembly should pay attention to the order of assembly of the components and external wiring position, in order to reassemble and wiring correct, but also to check whether the oil mist spray hole is blocked, whether the lubricant is sufficient.
4, air leakage: air leakage will cause insufficient air pressure, making it difficult to open and close the forced valve, due to damage to the sealing gasket or slide valve wear and tear caused by several cavity tampering air. In dealing with the switching system of the solenoid valve failure, should choose the appropriate time, and so on the solenoid valve in the loss of power to deal with, if the processing is not completed within a switching gap, the switching system can be suspended, from the processing.
