The motor of the fuel dispenser must be explosion-proof. Its power cord is routed through the steel pipe into the electrical box. The connection of the protective tube should be sealed, and the motor shell should be grounded firmly. When repairs and inspections of electrical parts require the cover of the electrical box to be removed, it is necessary to strengthen safety and fire prevention measures, and no combustibles should be placed in the workplace. At the same time, the power supply should be cut off to prevent the electrical contacts from jumping arc to detonate. Form a fire.
Do a good job in the protection and maintenance of the fuel dispenser. During the operation, you need to check the operation status of the oil pump frequently. If the oil pump is heated, abnormal noise, etc., it should be shut down immediately to find out the cause and troubleshoot in time. There must be a dedicated person for regular safety inspections, each inspection must be recorded, and the inspection problems must be dealt with in a timely manner.
When the internal pipe fittings of the tanker are damaged or aged, the phenomenon of oil leakage occurs. If you do not deliberately check it, it is not easy to detect. If it is not discovered in time, a serious security accident may occur. So if the tanker chassis is buried in sand and the oil droplets are quickly absorbed by the sand, how to quickly determine whether the tanker chassis is leaking? Only visual observation cannot achieve 24-hour continuous monitoring of the tanker chassis. Therefore, gas stations should use leak detection sensors to continuously and effectively monitor the leakage of the tanker chassis.
Excessive noise of the fuel dispenser is caused by the following reasons: the overflow valve of the vane pump is stuck and cannot be opened or the adjustment screw is too tight; the filter of the oil and gas separator is blocked, and the oil pipeline is too long and too thin to form the load of the vane pump. Increased, noise occurs; the blade of the vane pump is stuck, which causes the pulsation of the output oil to increase, causing the machine to produce noise and vibration; the V-belt is too tight, and the sliding bearing of the vane pump is worn, causing the noise of the dispenser to increase; the vane or spring ( Piece) is damaged, causing the noise of the dispenser to increase; the pipe in the machine vibrates, the solution is to replace the shock-proof hose.
