A gas station is a supplementary station for retailing gasoline and motor oil for automobiles and other motor vehicles, generally adding fuel oil, lubricating oil, and the like. Because the petroleum products sold at gas stations have the characteristics of flammable explosion, volatile, easy to leak, and easy to collect static charge, the gas station takes "safety" as the first criterion. Fireworks are strictly forbidden in gas stations. It is strictly forbidden to engage in operations that may produce sparks. It is strictly forbidden to add gasoline to the carburet and the barrel of the car. All stations must be turned off when refueling. All dangerous goods are strictly prohibited from entering the station.
The tanker is an oil metering device that directly fuels the motor vehicle. It forms a complete oil supply system with oil tanks, pipelines, and pipe fittings. The tanker is composed of four parts: oil pump, oil separator, meter, counter and other components such as electric motor and oil gun. Any type of tanker can be regarded as the big assembly and other simple parts. Composition.
At present, there are many types of tankers used in gas stations, ranging from mechanical and electronic to computerized automatic tankers. The flow rate of the tanker can be divided into 50-60 liters/min and 80-90 liters/min. The small-flow tanker is suitable for refueling in small cars and vans; the large-flow tanker is suitable for refueling large passenger cars and container trucks. The basic structure (mechanical transmission part) of the various tankers is the same. The difference between mechanical and electronic is that the digital display device is different, and the electronic type can be used together with the microcomputer to achieve the purpose of automatic operation.
Domestically used tankers are available in both ground fixed tankers and suspended tankers.
The fixed tanker can make the position of the car clear, the procedure of the refueling operation is not easy to be chaotic, the work efficiency is high, the price is cheap, the fault is less, and the maintenance is convenient. However, the floor space is large, the fueling range is small, the vehicle must be refueled within the predetermined range, and the self-priming capacity of the self-priming pump of the fuel dispenser is limited. The distance from the underground oil tank must not exceed 20-25 meters, and the suction height is 4 meters. Otherwise, Affect the refueling of the tanker.
The hanging tanker can make full use of the limited space. The fixing of the oil pipeline can be moved to the lateral direction by 12 meters. The fueling range is large and the radius can reach more than 4 meters. The fueling vehicle can freely carry in and does not affect the traffic of the vehicle; the amount of fuel is displayed on the screen. However, the parking position is not clear, which is easy to cause work confusion; the equipment mainly relies on imports, so the equipment price is high, and it is difficult to repair the fault. It is necessary to separate the pump room and lengthen the pipeline, and the total investment is increased.
