Electromagnetic pulse valve common problems and solutions

Electromagnetic pulse valve common problems and solutions:
First, the electromagnetic pulse valve in the installation, often appear problems and solutions:
1. Failure phenomenon: Some valves do not work, other valves are normal; Analysis of reason: Check valve connection and coil; Remedy: Replace parts.
2. Failure phenomenon: All valves cannot be opened, but the pilot part has an action; Analysis of the reasons: Check whether the air bag pressure is too low; Remedy: Check the leak.
3, the phenomenon of failure: some valves can not be closed with leakage; analysis of the reasons: there are impurities adsorbed on the diaphragm, moving iron core stuck phenomenon; elimination method: clean the diaphragm, check the diaphragm is complete, check the moving core And gas plugs.
4. Failure phenomenon: The solenoid valve closes slowly; Analysis of the cause: The orifice of the diaphragm is blocked; Remedy method: Dredge diaphragm orifice.
5, the failure phenomenon: all valves can not be closed, there is a leak, the air bag pressure can not be established; cause analysis: 1, Y-valve the same air bag of a certain number of valves leak caused by the illusion of all valves leak; 2,Z Type valve, the valve inlet and the injection port installed opposite; the corresponding exclusion method: 1, check the leak; 2, re-install.
Second, the electromagnetic pulse valve in the process of use, often problems and solutions:
1, the phenomenon of failure: the coil fever burned; cause analysis: long time power; exclusion method: check the control system's working condition.
2, the phenomenon of failure: the ambient temperature is lower than -20C °, the valve has a leak or can not be opened; cause analysis: the ambient temperature is too low, the valve has icing phenomenon; elimination method: pay attention to insulation.
3, the phenomenon of failure: there is a voltage but the valve does not move; analysis of reasons: the diaphragm is damaged or blocked orifice; exclusion method: timely replacement of accessories.
4. Failure phenomenon: Some valves leak, the diaphragm is not dead, the valve is always open; Analysis of the reasons: there are impurities adsorbed on the diaphragm, the leading damage, moving iron core stuck phenomenon; elimination method: cleaning the diaphragm, check Whether the diaphragm is complete or not, check the moving iron core and gas plug, and replace the accessories in time.
Electromagnetic pulse valve instructions:
The working pressure of the electromagnetic pulse valve must be strictly controlled at 0.2Mpa~0.6MPa, and the requirement is relatively stable. Before the electromagnetic pulse valve is installed, the impurities in the airbag must be strictly cleaned; the compressed air must be strictly controlled as a clean and dry gas source.
