Solenoid Valve 02250125-657 For Sullair Air compressor

Through some common solenoid valve does not work,

1 Screw type air compressor mechanical magnetic valve wiring head loose or falling, solenoid valve is not electricity, can tighten the head to solve the problem.

2 Screw air compressor electromechanical magnetic valve coil burned out. The solenoid valve coil is burned out. Remove the wiring of the solenoid valve and measure it with a multimeter. If the solenoid valve coil is open, it is burned out. The coil is damp, resulting in poor insulation and magnetic leakage, forming the coil current is too large and burned, so to avoid rain into the solenoid valve. In addition, the spring is too hard, the reaction force is too large, the coil turns too small, suction can also make the coil incinerate. When urgent disposal, the manual button on the coil can be hit from the "0" position to the "1" position during normal operation to make the valve open.

3 Solenoid valve of screw air compressor is stuck. Solenoid valve slide sleeve and spool cooperation gap is very small (less than 0.008m), usually are single installation, when there are mechanical impurities into or too little lubricating oil, it is easy to jam.

Disposal method: steel wire can be used from the head hole into the hole, so that it springs back. The thorough solution is to remove the solenoid valve, take out the spool and the spool sleeve, clean with CCI4, so that the spool in the valve sleeve action sensitive. When disassembling, attention should be paid to the installation sequence and external wiring orientation of each component, so as to reinstall and connect correctly, and check whether the oil spray hole of the oil mist is blocked and whether the lubricating oil is satisfied.

4 Solenoid valve of screw compressor leaks air. Leakage will form a lack of air pressure, making the valve open and close difficult, the reason is the damage of the sealing gasket or the wear of the slide valve and the formation of several cavity gas.
