Analysis of possible causes of failure of Baode solenoid valve coil

Baode Solenoid Valve is an automatic basic component used to control the direction of the fluid. It is an actuator; it is usually used on mechanical control and industrial valves to control the direction of the medium to control the valve switch.
 
There is a closed cavity in the Baode solenoid valve. There are through holes in different positions. Each hole leads to a different oil pipe. The middle of the cavity is a valve. On both sides are two electromagnets. Which side of the magnet coil is energized? Which side is attracted to, by controlling the movement of the valve body to block or leak different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then pushed by the pressure of the oil The piston of the cylinder, the piston drives the piston rod, and the piston rod drives the mechanical device to move. This controls the mechanical motion by controlling the current of the electromagnet.
 
There are many reasons for the burnt of the Baode solenoid valve coil. If the valve core is stuck, the voltage is too high, the ambient temperature is too high or too low, and the vibration of the pipeline or equipment is unstable, the Baode solenoid valve coil will be heated or burned. The valve stem of the German solenoid valve is stuck, which is the main factor causing the heating of the Bode solenoid valve coil or even the solenoid valve coil. Generally, it is divided into two cases.
 
Internal factors of Baode solenoid valve: The clearance between the sliding sleeve and the valve core is very small (less than 0.008mm). It is usually assembled in one piece. When mechanical impurities are brought in or the lubricating oil is too small, it is easy to get stuck. The treatment method can use a steel wire to break in from the small hole of the head to make it bounce back. The fundamental solution is to remove the solenoid valve, take out the valve plug and the valve core sleeve, and clean it with CCI4, so that the valve core can move flexibly in the valve sleeve. When disassembling, pay attention to the assembly sequence of each component and the external wiring position, so as to reassemble and wire correctly, and check whether the oil mist injection hole is blocked and the lubricating oil is sufficient.
 
External factors of Baode solenoid valve: stable operation and cleanness of fluid medium are inseparable. We have many customers who use the solenoid valve on pure water. It has been used for more than five years and still has a lot of media. Some fine particles or media calcification, these tiny substances will slowly adhere to the valve core, and gradually become harder. Many customers report that the first night is still running normally. By the next morning, the solenoid valve will not open, and it will be removed. At first glance, there was a thick layer of calcification deposited on the spool. Just like the home thermos.
