When the pressure of the fuel dispenser is too high, the service life of the tanker will be shortened, which will cause the following failures: excessive vibration of the tanker, digital switching of the switch, damage to the oil pump, damage to the solenoid valve diaphragm, oil leakage of each joint component, oil sight The glass bursts, the oil leaks after the oil gun is closed. When refueling, the oil and gas evaporates too much, causing the oil smell in the gas station to increase, which is not only detrimental to environmental protection, but also a safety hazard.
The fuel dispenser is well grounded, which can effectively eliminate static electricity, filter out external disturbances, add the working stability of the tanker computer motherboard and the security of data parameters, which can well eliminate the potential safety hazards caused by static electricity. The oil gun, movable joint, rubber hose and oil sight should be connected reliably. If the oil gun is poorly grounded, the static electricity on the vehicle cannot be released through the oil gun, movable joint, hose, oil sight, fuel dispenser, ground wire, and the ground when refueling, which will cause the oil gun and the vehicle fuel tank when refueling. There is a fire phenomenon, which may cause a dangerous accident.
The first is not to modify without authorization. The pipeline above the tanker is fixed. In order to obtain higher refueling efficiency, some gas stations will add a branch pipeline on the tanker. This approach is absolutely unusable and has hidden dangers. There is also the fact that two refueling guns cannot use the same refueling machine. The newly added tanker must be strictly debugged before use, and the debris inside can be cleared out before it can be used normally.
The metering gun of the fuel dispenser manufacturer generally has a self-sealing function or a metering function, so it is generally called a self-sealing gun or a metering gun. There are some differences between the two. The self-sealing gun is if the barrel touches the oil. It will be automatically turned off, and there is a metering display on the metering gun, which can clearly see the relevant data of the oil.
