Solenoid pneumatic valve is not action any troubleshooting methods are there?

（ ） Import solenoid pneumatic valve terminal is loose or falls off thrum, solenoid pneumatic valve can not electricity, can tighten thread ends.
　　（ ） Imported electromagnetic solenoid coil burn out, can remove the solenoid pneumatic valve connection, measured with a multimeter, if open circuit, the pneumatic electromagnetic valve coil burn out.
coil be affected with damp be affected with damp, reasons caused bad insulation and magnetic flux leakage, causing excessive current in coil and burned down, so to prevent rain water from entering the solenoid pneumatic valve. In addition, the spring quality, reaction force is too large, the coil number of turns is too little, not enough suction also coil may be destroyed. When emergency treatment, but the manual button on the coil by the normal work of '' hit' a ', make the pneumatic valve to open.
　　（ ） Solenoid pneumatic valve stuck. Slide of pneumatic valve pneumatic valve and pneumatic valve core set of fit clearance is small ( Less than. mm） , are generally single assembly, when mechanical impurities into or lubricating oil is too little, it is easy to get stuck. Treatment methods available wire holes stab, from the head to make it back. Fundamental solution is to solenoid pneumatic valve will be removed, remove the pneumatic valve core and pneumatic valve core sleeve, clean with CCI, makes the pneumatic valve core in the pneumatic valve set inside the flexible motion. Removal should be paid attention to when all parts, assembly sequence and wiring position to reassemble and wiring is correct, also check oil mist detector injection hole blockage, lubricating oil is enough.
　　（ ） Air leakage. Leakage will cause the air pressure is insufficient, make it easier for enforcement of the pneumatic valve opening and closing, the reason is that sealing gasket pneumatic valve damage or sliding wear several cavity caused by gas.
