Instructions:
1. check the components before use, whether they are damaged during transportation, then install and use them.
2. when installing, please pay attention to the direction of gas flow and whether the nozzle is correct.
3. Installation, pay special attention to whether the voltage meets the requirements, the whole machine debugging, it is recommended to use manual device debugging, and then power-on debugging.
4. please pay attention to dust prevention and suggest installing muffler at the exhaust port.
5.When connecting the pipeline, pay attention to the winding of the stop strip not to exceed the tooth end surface, and pay attention to the elimination of pipe joints, metal particles in the pipe, dust and oil pollution.
Fault and elimination
First, the Solenoid Valve does not work after energizing.
Check whether power wiring is bad, re wiring and connector connection.
Check whether the supply voltage is within the range of + - to normal location.
Whether the coil is removed or re welded
Coil short circuit to replace coil
Is the working pressure difference inappropriate? Adjust the differential pressure to replace the equivalent solenoid valve.
The fluid temperature is too high to replace the proportionate solenoid valve.
Impurities jam the main valve core and the moving iron core of the solenoid valve for cleaning, if the seal is damaged, replace the seal and install the filter
The viscosity of the liquid is too high, the frequency is too high, and the life has arrived.
Two, solenoid valve can not be closed.
Seal of main spool or iron core has been damaged. Replace seal.
If the fluid temperature and viscosity are too high, replace the counterpart solenoid valves.
The impurity enters the electromagnetic valve to produce the valve core or the moving iron core.
The life of springs has arrived or deformed to replace.
Throttle hole balance hole clogging and timely cleaning
Working frequency is too high or life expectancy has changed.
Three, other circumstances
Internal leakage to check whether the seal is damaged, and whether the spring is assembled badly.
Leakage: connect loosening or seal is broken. Tighten screws or replace seals.
There is noise when power is switched on, and the fastener on the head is loose and tightened. Voltage fluctuation is not within the allowable range, adjust the voltage. Clean or replace the impurities or uneven surfaces of the core.
