Explosion-proof solenoid valve malfunction in the tanker how to solve?
China used plant network zhang shan at gas stations, sometimes will meet or no oil tankers oil slow, there are many reasons that cause this situation, some of which are the result of a damaged explosion-proof solenoid valves.
Usually for repair, in order to save trouble, put the inside of the solenoid valve diaphragm off or switching to reinstall, make the solenoid valve connected effect, some people think that this is fixed.
This does make the oil tankers out, but will leave 'catastrophic' consequences -

Can't quantitative come on and come on don't count.
When quantitative refueling tanker, electromagnetic valve is opened entirely, when the amount remaining.
Rose.
Rose, close large flow signal from computer, continue to go to the preset number, small flow finally close small flow rate, closed motor, that there will not be a super pay oil phenomenon.
Is when you take away or put inside the solenoid valve diaphragm head, gas quantity reaches the preset number, signal from the motherboard can't closed oil circuit, continue to the big flow, make the display panel display number is greater than the preset refueling.
When double bolt in the above situation, a gun in the normal, the other a gun because of electromagnetic valve is broken, can't shut down oil, in the case of no boot can also give oil, but because of the mainboard didn't get the boot signal, so can't count, there are some hidden dangers.
Therefore, when explosion-proof solenoid valve cannot open result in oil tankers, should be the correct maintenance.
First of all, should check the explosion-proof solenoid valve control circuit part, such as whether the zero line is entering, light valve plate damage, etc.
Second, check explosion-proof solenoid valve failure itself, such as whether the coil inside the valve open circuit, such as valve film hole blockage in the valve failure.
If it is explosion-proof solenoid valve failure and cannot repair itself, a new rice cooker solenoid valve should be replaced.
Also should pay attention to when buying explosion-proof solenoid valve model should be replaced with consistent.
