Q: What are the problems of LED explosion-proof lights in gas stations?

    A: Due to the particularity of LED explosion-proof lamps, the safety requirements for them are relatively high. In gas stations, there are the following common problems:

1. The laying of electrical lines and electrical equipment does not meet the requirements of fire safety technology: the lighting lines in the business room and on duty room of many gas stations are not laid according to the requirements, and explosion-proof lamps and switches are not used. Although some gas stations use explosion-proof electricity in the construction, they are not used in strict accordance with the requirements in the late management, and the explosion-proof electricity has lost its due role due to the unauthorized connection and pulling of wires.
    2. There is no electrostatic grounding device for the unloading site of the automobile tank truck: it is found in the inspection that the supervisors of many gas stations know that lightning protection and anti-static device should be set up, but the problems of electrostatic grounding device should be set up for the unloading site of the automobile tank truck are ignored. A lot of static electricity is generated when the car tank car is running. If there is no anti-static grounding device at the oil unloading site, the static conductance on the car body can not be removed. It is easy to cause sparks to make the oil products explode when the oil is unloaded. According to the specification, the unloading site must be equipped with electrostatic grounding device, the grounding resistance should not be more than 100 ohms.

3. Underground oil tank ventilation pipe mouth fire retardant device installation error: some both underground and aboveground tanks are set as breathing valve, or are set as flame arrestor. The specification clearly stipulates that the underground oil tank should be equipped with a separate breathing tube, whose diameter should not be less than 50 mm, and a flame arrestor must be installed. The distance between the nozzle and the ground should not be less than 4 meters. Breathing pipes laid up along the walls (columns) of the building should be 1 meter higher than the building, and the net distance from the doors and Windows should not be less than 3 meters. This is mainly to prevent the fire outside the tank into the accident. Buried tank is different from the oil tank of gas station, buried DeYou tank gas space between day and night temperature has no obvious change, won't produce little breath, and breathe the respiration valve to reduce product loss doesn't work, so only need to install the flame arrester, without the need for the respiration valve, the installation of the breather valve but increases the resistance when the unloading, director of the unloading time, But above-ground tanks should be equipped with breathing valves.
    4. LED explosion-proof lamp tank car adopts open type and splash type oil discharge. LED explosion-proof lights of the automobile tank truck must be used to discharge oil in a closed way, and the connection between the discharge pipe and the oil tank inlet pipe should be quick joints. Because the unsealed unloading of oil is easy to cause the volatilization of oil products, increase the loss, and the oil and gas will spread along the ground and easily cause fire if it meets the fire source. The spatter unloading is easy to make the oil produce static electricity spark, cause fire. There are many cases of fire caused by static electricity during oil unloading, which is caused by static electricity and spark caused by oil spatter caused by oil injection pipe not inserted into the bottom of tank during oil unloading. Therefore, when the buried oil tank of the gas station is set and installed, it must be extended to the tank 20 centimeters from the tank bottom according to the requirements of the "Design Code for Small Oil Depot and Automobile Gas Station". At the same time, when unloading oil, the flow rate of oil should be strictly controlled to prevent the static electricity from flowing too fast.
