Common Troubleshooting Solutions For Solenoid Valves

1. The wiring head of the solenoid valve is loose or the wire knot falls down. The solenoid valve is not electric, and the wire knot can be tightened.
2, The solenoid valve solenoid coil burned, can be removed from the wiring of the solenoid valve, measured with a multimeter, if the lead, the solenoid valve solenoid coil burned. For the reason of the electromagnetic coil moisture, causing the insulation layer is not good and magnetic leakage, resulting in excessive electrical flow in the electromagnetic coil and damage, so to avoid the precipitation into the solenoid valve. In addition, the torsion spring is solid, the recoil is too large, the number of turns is too small, and the insufficient adsorption force can also cause the electromagnetic coil to be damaged. In case of emergency, the manual key on the electromagnetic coil can be inserted into the "1" position from the "0" position in normal operation to make the valve open.
3, solenoid valve stuck: solenoid valve vane pump sleeve and valve heart collocation gap is not big (less than 0.008mm), basically all parts installation, when there is mechanical equipment residue brought into or hydraulic oil is too little, it is very easy to stuck. The solution can be a small round hole from the top of the wire inserted, so that it springs back. The fundamental solution is to remove the pulse solenoid valve, take off the valve core and seat sleeve, clean with CCI4, and promote the valve core in the pump sleeve position easily. When disassembling and assembling, we should pay attention to the installation order and internal wiring position of each component, so as to facilitate reassembly and proper wiring. It is also necessary to check whether the oil pump hole of the pneumatic triad is blocked and whether the grease is sufficient.
4, steam leakage: gas will lead to insufficient gas pressure, forcing the mandatory valve to open and close difficult, the reason is the destruction of the sealing gasket or valve body damage and lead to the number of cavity channeling. In solving the common faults of the solenoid valve of the conversion system software, reasonable opportunities should be selected, such as stainless steel solenoid valve in the jump stop to solve, if not completed in a conversion gap, the conversion system software can be suspended, calm solution.
