After all the oil tanks in gas stations in buried storage tanks are used for a period of time, condensate will accumulate into the bottom of the tank due to the temperature difference, accelerate the emulsification of fuel oil, corrode the tank walls, and gradually increase the sludge, which will affect the oil products. the quality of. At the same time, in order to protect energy and the environment, new regulations require the addition of ethanol and reducing the sulphur content of diesel. The new types of fuels that emerged, such as ethanol gasoline, are very unstable and are more likely to be contaminated. If the pollution is increased without timely processing, it will bring greater cost to the fueling station, such as increasing filter replacement times, prolonging the refueling time, bacterial contamination, or phase separation causing fuel damage. The damage to vehicles caused by oil quality problems occurs from time to time, not only causing undue losses to the owner, but also affecting the social reputation and economic benefits of the refined oil sales companies. Therefore, it is very important to clean the oil tanks regularly and on time. important. Newer fuel types have emerged and the government’s safety regulations have become increasingly stringent, requiring S/F underground oil storage tanks to be cleaner. Industry experts agreed that S/F underground oil storage tanks need to be better maintained, and that they can no longer be cleaned after tanking.
The S/F underground oil storage tank cleaning process at the gas station is: after emptying the tank, insert the Gammajie 10 nozzle into the tank through a hole of not less than 4 inches, and move the connecting pipe up and down to adjust the cleaning nozzle to the maximum. Good position (near the center axis of the tank body), through a booster pump to push the water flow into the cleaning nozzle, the pressurized jet drives the nozzle, 360 degree spherical automatic rotary jet cleaning, after 100 minutes of cleaning cycle of about 10 minutes, complete 100% The inner surface of the tank is cleaned. Oil sludge, bacteria, sludge, dirt, and other contaminants on the tank wall are flushed into a solution that is easily vacuumed. After the cleaning is started, the vacuum pumping system can be activated to extract the waste liquid or sludge containing petrol/diesel at the bottom of the tank so as to clean it while removing the dirt. After a complete cleaning cycle time or when clear water is seen The booster pump can be stopped, and the cleaning liquid at the bottom of the tank can be drained as much as possible to complete the tank cleaning. When cleaning oil tanks with different structures, adjust the specific cleaning construction methods according to the actual tank conditions.
