Solenoid valve spool valve sleeve and spool with a small gap, are generally one-piece assembly

Solenoid valve coil burned out, remove the solenoid valve wiring, measured with a multimeter, if open, the solenoid valve coil burned out. Moisture causes the coil, magnetic flux leakage caused by Electric energy meter, causing the coil current is too large to burn, so to prevent rainwater from Voltage stabilizer the solenoid valve. In addition, strong spring, reaction force is too large, too few coil turns, suction can not make the coil burnt. Emergency treatment, can be manual button on the coil from the normal working hours of the "0" bit hit "1" bit, making the valve opens.
Solenoid valve spool valve sleeve and spool with a small gap (less than 0.008mm), are generally one-piece assembly, when there are mechanical impurities into or too little lubricant, it is easy to get stuck. electric meter are available hold into the wire hole from the head to make it bounce. The fundamental solution is to remove the solenoid valve, remove the spool and spool cover, with CCI4 cleaning kit allows flexible movement of the valve spool. Demolition should pay attention to the various components of the assembly sequence, and external wiring position for re-assembly and wiring is correct, also check whether the plug hole injector lubricator, lubricant is adequate.
