Background
A gasoline station refers to a station for replenishing retail gasoline and engine oil, typically with added fuel oil, lubricating oil, etc., that serves automobiles and other motor vehicles. Because the petroleum commodities sold by the gas station have the characteristics of easy combustion and explosion, easy volatilization, easy leakage and easy static charge accumulation, the gas station takes 'safety' as a first criterion. The gas station is forbidden to be filled with gasoline in a carburetor and a dual barrel of an automobile, and all stations need to be flameout first when entering the station and refuel, and all dangerous goods entering the station are forbidden.
The fuel charger is a fuel delivery metering device for directly charging motor vehicles. It forms a complete oil supply system together with oil tank, pipeline, pipe fitting valve, etc. The fuel dispenser is composed of four large assemblies of an oil pump, an oil-gas separator, a meter and a counter, and other parts such as a motor and an oil gun, and any fuel dispenser can be regarded as being composed of the large assembly and other simple parts.
At present, the fuel dispensers adopted by gas stations are various in scale, from mechanical type, electronic type to computer automatic fuel dispensers. The flow rate of the fuel dispenser can be divided into 50-60 liters/minute and 80-90 liters/minute. The small-flow oiling machine is suitable for oiling cars and vans; the large-flow oiling machine is suitable for oiling large buses and container trucks. The basic structure (mechanical transmission portion) of the various fuel dispensers is consistent. The difference between the mechanical type and the electronic type lies in the difference of the digital display device, and the electronic type can be matched with a microcomputer for use, thereby achieving the purpose of automatic operation.
