With the development of energy markets and the rapid increase of automobile consumption in China, the fuel supply is closer to the daily life of people and more important. Gasoline, diesel oil and the like which are filled into various motor vehicles by a gas station belong to light fuels, and have higher fire and explosion risks. In particular, gasoline is flammable, explosive, easy to accumulate static electricity, easy to volatilize, easy to diffuse, easy to flow, easy to be subject to thermal expansion, toxic and corrosive. Relative density of gasoline (0.710-0.730) g/cm3The volatility is strong, the steam is heavier than air (the relative density is 3.0-4.0) and is not easy to diffuse, the explosion limit is 1.4% -7.6%, the minimum ignition energy of the steam is only 0.2mJ, and the gasoline steam is easy to burn and detonate when meeting open fire or electrostatic sparks. GB50156 design and construction Standard of refueling and gas station makes fire prevention regulations on site selection of gas stations, safety distance of station periphery, fire prevention distance of equipment in stations and plane arrangement of oil stations, including requirements on fire-fighting facilities and water supply and drainage. However, once a fire disaster occurs in the daily operation of the gas station, the gas station is not easy to put out and has serious consequences. The oiling machine and the gas station find the hidden danger of fire early and eliminate the hidden danger of fire early, and the fire prevention and the early fire fighting are very important and should be prevented from being burnt.
The fuel oil charger is one explosion-proof electromechanical product and relates to explosion-proof electric equipment and explosion-proof non-electric equipment. The oiling machine is divided into a danger 1 area, a danger 2 area and a safety area according to GB50156 national standard, a hydraulic tank is the danger 1 area, and a computer box is the safety area. The safety design, the test inspection and the protection measures of the oiling machine are carried out according to the part 1 of the anti-explosion safety technology of the fuel filling station of GB 22380.1: the anti-explosion safety technology of the fuel oiling machine reaches the anti-explosion safety standard. As the using time of the oiling machine is prolonged, the environment is changed, the sealing element is aged, and the maintenance is not timely, the anti-explosion type of the oiling machine has the possibility of failure, and potential safety hazards are caused.
On one hand, the fuel vapor combustible concentration is increased due to the failure of non-electric equipment in the hydraulic tank of the fuel dispenser. For example, an oil pump, a flow measurement converter, a filter and a pipeline interface in a hydraulic tank of the oiling machine cause interface loosening, sealing failure, oil leakage or oil leakage due to the water hammer effect of a hydraulic pipeline; the oil gas recovery return air passage joint is disengaged due to the vibration of the vacuum pump, and oil gas directly overflows to the outside of the pipe. On the other hand, an ignition source is provided in the hydraulic tank due to explosion-proof failure of the electrical equipment. Such as abnormal temperature rise of explosion-proof motor coils and explosion-proof electromagnetic valve coils; when a terminal in the explosion-proof control box is in fault and sparks occur, the joint surface of the explosion-proof box is scratched or foreign matters exist, the sealing surface fails, and the cable joint pressing rubber ring is aged or lost; the diesel low-temperature heating module is explosion-proof, invalid and overheated to become an ignition source; the grounding terminal of the electrical component is corroded and has poor contact, so that the resistance is overlarge and electrostatic sparks occur; the abnormal temperature rise caused by the short-circuit fault of the cable becomes an ignition source and the like.
The oiling machine computer box body used as a safety area has potential safety hazards inside. Oil gas does not normally exist in the computer box, and the electrical component can be non-explosion-proof. The flame-retardant and combustible material comprises a PCB (printed circuit board), a transformer, a relay, a polyvinyl chloride cable, a plastic plug, a component plastic shell, a plastic wiring groove and the like. Generally, the ignition source is caused by burning out of the electric appliance, short circuit of the electric appliance or aging of the electric wire.
