Q: tanker solenoid valve damaged, how to deal with? A: At gas stations, oil tankers sometimes encounter slow or no oil out of oil, there are many reasons for this situation, some of them caused by damage to the solenoid valve. Usually maintenance, in order to save trouble, put the solenoid valve inside the diaphragm removed or re-install, the solenoid valve to play the role of connectivity, and some people think so fixed. This will indeed drain the tanker, but will leave "catastrophic" consequences - not counting and refueling without counting. When the tanker refueling quantitatively, the solenoid valve is fully open, when the fuel left 0.3 liters to 0.5 liters, the computer sends a signal to close the large flow, a small flow to refueling to the preset number, and finally close the small flow, turn off the motor, so Will not appear over the oil phenomenon. When the solenoid valve inside the diaphragm removed or U-turn use, the number of refueling reaches the preset number, the signal sent by the motherboard can not turn off the oil, continue to flow to refuel, so that the number of display panel is greater than the preset number of refueling. When the double-gun machine when the above situation, a gun in the normal refueling, the other gun due to a broken solenoid valve, and can not turn off the oil in the boot case can also be out of oil, but because the motherboard did not get the boot signal , So can not count, there is a certain risk. Therefore, when the solenoid valve can not be opened resulting in not oil dispenser, it should be properly repaired. First of all, should check the solenoid valve control circuit part, such as zero line is entered, light valve plate is damaged. Second, check the solenoid valve itself fault, such as the valve coil is open, the valve hole is blocked and other valve failure. If the solenoid valve itself fails and can not be repaired, replace the new solenoid valve. Also in the purchase of solenoid valve to pay attention to the model to be replaced with the same.
