A common fault analysis of import solenoid pneumatic valve

what are the common faults import solenoid pneumatic valve? Solenoid pneumatic valve switch failure will directly affect the pneumatic valve and adjust the action of pneumatic valve, common fault solenoid pneumatic valve is not action, embodied in the following respects:
pneumatic valve, electromagnetic wire head is loose or falls off thrum, electromagnetic pneumatic valve can not electricity, can tighten thread ends.
pneumatic valve, electromagnetic 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.
pneumatic valve, electromagnetic jamming: 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, very 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.
and air: air 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. In dealing with the electromagnetic switch system pneumatic valve failure, should choose the appropriate time, such as the electromagnetic pneumatic valve in a loss of power, the if processing is not down in a switch gap, switched systems can be suspended, calmly deal with.
