The methods for checking diesel generator pipeline oil leakage mainly include the following:
1. Exhaust the air in the oil circuit and start the unit: exhaust the air in the diesel generator oil circuit, then start the unit, and find the place where the diesel is leaking, which is the leak.
2. Check the injection pump bleed screw: loosen the injection pump bleed screw, and use a hand oil pump to extract oil. If a large amount of bubble oil is found to be discharged from the bleed screw, and the bubbles do not disappear after repeated hand pumping, it can be determined that there is a leak in the low-pressure oil circuit from the oil tank to the oil pump. The section of the pipeline should be removed, pressurized gas should be passed in and placed in water, and the place where bubbles are found is the leak.
3. Check the gaskets at the pipeline joints: Various gaskets at the pipeline joints will also cause leaks due to improper installation, deformation, aging and damage. Before conducting a detailed inspection of the pipeline, these nodes should be checked first.
4. Check the hard oil pipe outside the fuel tank: If no problems are found in the above nodes, you can check a section of the hard oil pipe outside the fuel tank, find the oil leak point and plug it, but if there is a large leak point, it is recommended to replace the new oil pipe.
Hazards and preventive measures of diesel generator oil leakage:
1. Hazards: Diesel generator oil leakage will cause fuel waste, environmental pollution and equipment damage, and in severe cases may cause fire and other safety accidents.
2. Preventive measures: Regularly check and maintain the equipment, ensure the sealing of the pipeline and joints, replace aging and damaged parts in time, keep the equipment clean and dry, and avoid fuel leakage.
Through the above methods, you can better troubleshoot and solve the oil leakage problem of diesel generators to ensure the normal operation and safe use of the equipment.
