Solenoid pneumatic valve failure and elimination method

pneumatic valve failure will directly affect the electromagnetic switch is the action of pneumatic valve and control valve, and the common faults of electromagnetic pneumatic valve does not move, should investigate the following aspects:
( ） Solenoid pneumatic valve stuck. Pneumatic valve with a small gap (electromagnetic slip Less than. mm） , general assembly, when mechanical impurities into or lubricating oil is too little, pneumatic valve and pneumatic valve core is easy to get stuck. Treatment can be from the head into the line hole, make its bounce. Fundamental solution is to remove the electromagnetic pneumatic valve, pneumatic valve to take out the core and pneumatic valve core set of CCI and cleaning tools, allows for the flexible pneumatic valve core movement. Remove the various components of the assembly sequence should be paid attention to when and to the location of the assembly and connection of external connection is correct, also check whether the injector plug loopholes oil mist, oil is enough.
( ） Electromagnetic solenoid coil is burnt out, you can delete the solenoid pneumatic valve connection, measured with a multimeter, if open, electromagnetic solenoid coil burn out.
water coil, a magnetic flux leakage caused by defective insulation, cause and burning coil current is too high, so to prevent the flooding into the solenoid pneumatic valve. In addition, the strong spring, reaction force is too large, the coil number of turns is too little, not enough suction also coil may be destroyed. Emergency treatment, can be manually from the 'hit' 'a bit' coil buttons to work properly, make the pneumatic valve to open.
( ） Electromagnetic air valve head loose connection or tripping, electric solenoid pneumatic valve should be tighten screw.
( ） Leaks. Insufficient pressure can lead to leakage, make difficulties forced open and close the pneumatic valve, because the pneumatic valve gasket damage or wear a few holes caused by gas.
switch and solenoid pneumatic valve fault handling system, should choose the appropriate time, so the power loss in the processing of the electromagnetic air valve, if handled the gap in constantly switch, switch system can stop the step.
