High Pressure Hydrogenation Valve failure and troubleshooting methods

The failure of the High Pressure Hydrogenation Valve will directly affect the operation of the switching valve and the regulating valve. Common failures include the failure of the High Pressure Hydrogenation Valve to operate. The following aspects should be checked:

(1) The High Pressure Hydrogenation Valve wiring head is loose or the wire head is detached. The High Pressure Hydrogenation Valve must not be powered on. The wire head can be tightened.
(2) The High Pressure Hydrogenation Valve coil is burned out. The wiring of the High Pressure Hydrogenation Valve can be removed and measured with a multimeter. If it is open, the High Pressure Hydrogenation Valve coil is burned out.
The reason is that the coil is damp, causing poor insulation and magnetic leakage, resulting in excessive current in the coil and burning. Therefore, rainwater should be prevented from entering the High Pressure Hydrogenation Valve. In addition, the spring is too hard, the reaction force is too large, the number of coil turns is too small, and the suction force is insufficient, which can also cause the coil to burn. In emergency treatment, the manual button on the coil can be turned from the "0" position during normal operation to the "1" position to open the valve.
(3) The High Pressure Hydrogenation Valve is stuck. The clearance between the sliding valve sleeve and the valve core of the High Pressure Hydrogenation Valve is very small (less than 0.008mm). It is generally assembled in one piece. When mechanical impurities are brought in or there is too little lubricating oil, it is easy to get stuck. The solution is to use a steel wire to poke it through the small hole in the head to make it rebound. The fundamental solution is to remove the High Pressure Hydrogenation Valve, take out the valve core and 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 to ensure correct reassembly and wiring. Also check whether the oil mist spray hole is blocked and whether the lubricating oil is sufficient.
(4) Leakage. 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 sliding valve is worn, causing several cavities to leak gas.
When dealing with the failure of the High Pressure Hydrogenation Valve in the switching system, you should choose an appropriate time and wait until the High Pressure Hydrogenation Valve is in a power-off state to deal with it. If the processing cannot be completed within a switching gap, the switching system can be paused and handled calmly.
