How to solve the problem that the water solenoid valve does not produce water? Why the water solenoid valve cannot be opened?

How to solve the problem that the water solenoid valve does not produce water? Reasons why the water solenoid valve cannot be opened. 1. The water solenoid valve connector is loose or the threads fall off. The solenoid valve cannot be powered. You can tighten the threads. 2. The water solenoid valve is stuck. The fitting gap between the slide valve sleeve and the valve core of the water solenoid valve is very small (less than 0.008mm). It is usually assembled in a single piece. When mechanical impurities are brought in or there is too little lubricating oil, it is easy to get stuck. The treatment method can be to insert a steel wire through the small hole in the head to make it bounce back. The fundamental solution is to disassemble 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, attention should be paid to the assembly sequence of each component and the position of external wiring so that reassembly and wiring are correct. Also check whether the oil spray hole of the lubricator is blocked and whether the lubricating oil is sufficient. 3. The water solenoid valve is leaking. Air leakage will cause insufficient air pressure, making it difficult to open and close the forced valve. The reason is that the sealing gasket is damaged or the slide valve is worn, causing air leakage in several cavities. When dealing with the solenoid valve failure of the switching system, you should choose the appropriate time to deal with it when the solenoid valve is out of power. If the solution cannot be completed within a switching gap, the switching system can be paused and dealt with calmly. 4. If the water solenoid valve coil is burned out, you can remove the wiring of the solenoid valve and measure it with a multimeter. If it is open circuit, the solenoid valve coil is burned out. Other common faults and solutions for water solenoid valves 1. Failure to operate when powered on Causes of the fault: 1. Poor contact in the power supply wiring 2. Power supply voltage changes are not within the allowable range 3. Coil short circuit or burned out Solution: 1. Connect the power cord 2. , Adjust the voltage to the normal range 3. Replace the coil 2. The fluid cannot pass through when opening the valve Causes of failure: 1. The fluid viscosity or temperature does not meet the requirements 2. Dirt and impurities are mixed around the valve core and the moving iron core 3. The filter in front of the valve or The pilot valve hole is blocked 4. The working frequency is too high or the service life has expired. 3. The fluid pressure or working pressure difference is abnormal. Solution: 1. Adjust the pressure or working pressure difference or replace the suitable product. 2. Replace the suitable product. 3. Clean the interior, and a filter valve must be installed in front of the valve. Clean the filter or pilot valve hole in time. 4. Change the product model or replace it with a new one. 4. The fluid cannot be cut off when the valve is closed. Reasons for the failure: The viscosity of the fluid does not meet the requirements. 1. The spring is deformed or has expired. 2. The valve seat is defective or has stolen goods attached to it. 3. The sealing gasket is protruding, defective or deformed. 4. The balance hole or throttle hole is clogged. 5. The operating frequency is too high or the lifespan has expired. 5. The fluid temperature does not meet the processing method: 1. Replace the appropriate product 2. Replace the appropriate product 3. Add a gasket or replace the spring 4. Clean, grind or update 5. Update, reassemble, clean in time or change the product model or replace it with a new product 6. How to deal with external leakage : 1. The pipe connection is loose 2. The outer seal of the pipe connection is damaged 3. Tighten the bolt or pipe thread 4. Replace the seal The above is how to solve the problem that the water solenoid valve does not discharge water.
