1. First unscrew the oil drain plug from the generator set's oil storage tank. After draining the oil, install the oil drain plug.
2. Remove the cover and filter from the diesel generator oil storage tank, and add fuel to the generator oil storage tank. The distance between the oil level and the bottom of the generator oil storage tank is about 15-20mm. .
3. Then connect the compressed air hose to the special spray head. The spray cleaning head is generally a metal pipe with an outer diameter of 12mm and a length of about 250mm. One end of the pipe is welded and plugged, and 4-5 small 1mm holes are drilled and the other end is connected. the garden hose.
4. Insert the hose with a spray head into the bottom of the generator set's oil storage tank.
5. Sealthe oil filling port with a clean cloth wrapped in cotton gauze, turn on the compressed air switch, and maintain an air pressure of 380-600 kPa for flushing. When flushing, the position of the spray head should be changed frequently so that sediment and adhesions can be returned with the oil.
6. After the spray cleaning head flushes the generator set oil storage tank, immediately remove the oil drain plug to drain the dirty oil. Repeat this cleaning process 2-3 times to remove dirt.
7. After cleaning the generator set oil storage tank, check whether the oil storage tank refueling filter is dirty or damaged and remove it at any time.
8. Check whether the vent valve of the generator set fuel tank cover is smooth. If the valve spring has no elasticity or is corroded, it must be repaired or replaced.
9. Finally, refill the oil and treat the air in the oil line.
10. If the generator oil storage tank leak is not subject to friction, welding can be used to seal the leak and then paint for protection.
11. If the leak is in the friction part of the generator set oil storage tank, the generator set oil storage tank should be removed, clean the inside of the oil storage tank with warm soapy water, then dry with compressed air. The mouth of the oil storage tank should face an uninhabited place (it is better to do it in the open air), and the leakage area should be heated with a soldering gun only after confirming that it there is. no residual fuel vapor in the oil storage tank of the generator set can be effectedkilled by welding to avoid accidents. After repair by welding, it must be painted for more protection.
The specific method of cleaning the fuel tank of the diesel generator is as follows:
⑴ Unscrew the oil drain plug of the fuel tank, drain the oil, and then reinstall the oil drain plug. .
⑵ Remove the fuel tank cap and filter, then add fuel to the tank.
⑶ Then connect the compressed air hose to the special spray head.
⑷ Insert the hose with the spray head into the bottom of the fuel tank.
⑸ Seal the oil filling port with a clean cloth wrapped in cotton gauze, turn on the compressed air switch, and when flushing, frequently change the position of the spray head so so that sediments and adherents can be returned. with the oil.
⑹ When the cleaning heade spray flushes the fuel tank, immediately remove the oil drain plug to drain the dirty oil. Repeat this cleaning process 2-3 times to remove dirt.
⑺ After cleaning the fuel tank, check the fuel tank filter for dirt or damage and treat it at any time.
⑻ Check whether the fuel tank cap vent valve is smooth. If the valve spring has no elasticity or is corroded, it must be repaired or replaced.
⑼ Finally, refill the oil and remove the air in the oil line.
Note: If there is too much sediment in the fuel tank, a large amount of impurities will enter the oil pipe, which will accelerate the filter clogging and wear of parts precision, affecting the normal use of the diesel generator. Therefore, the sediment present in the fuel tank must be regulatedcompletely eliminated.
