Diesel Engine Frequent Oil Leakage Fault Analysis?

First, first, how to check the diesel generator: first check whether the type, quantity and quality of the oil meet the requirements.
Second, diesel engine components of the combined surface is smooth, size processing is in line with the requirements. Dumping materials and die casting without sand holes, all kinds of paper pads, sealing rope, oil seals and screws must meet the requirements and tighten.
Third, whether the diesel engine lubrication is smooth, and whether it meets the requirements (the door oil hole on the subsequent column of the air cooled diesel engine is very important).
Fourth, whether the breathing of the diesel engine without negative pressure is smooth, whether it meets the requirements, whether the air in the cylinder leaks to the crankshaft, causing injection and oil leakage
Fifth, the diesel generator temperature is too high. Cooling and cooling performance must be good.
