Why does the exhaust pipe sometimes drip oil when the generator load is too low?
The following is a brief description by Jiangsu Lide Power Equipment Co., Ltd. Why does the generator drip oil when the generator set works under low load?
Because there are many types of pressure seals in the engine , such as between the cylinder liner, the piston and the piston ring, and between the turbocharger and the turbocharger rotor shaft, this type of seal is usually fully used when the engine has about 1/3 load. Effect, when the surface load is small, slight leakage may occur. Therefore, foreign engine manufacturers generally give emphasis in their manuals. If the unit is in a sub-branch under a small load, the following faults will occur as the operating time continues: 1. The piston-cylinder treasure knife is not old enough, the oil scatters into the combustion chamber, and the exhaust gas emits blue smoke. 2. For a supercharged diesel engine, due to low load, no load, and low boost pressure, the sealing effect of the supercharger oil seal is likely to decrease. The oil penetrates into the booster chamber and enters the cylinder along with the intake air. 3. A part of the oil flowing up to the cylinder participates in the combustion, some of the oil cannot be completely burned, and carbon deposits are formed at the valve, the intake port, the piston crown, the piston ring, etc., and some are discharged with the exhaust. In this way, engine oil will gradually accumulate in the exhaust duct of the cylinder, and carbon will also form. 4. When the supercharger's supercharged indoor engine oil accumulates to a certain degree, it will leak from the joint surface of the supercharger. 5. Long-term low-load operation will lead to more severe wear of moving parts and deterioration of the combustion environment of the engine, leading to the consequences of the overhaul period. Therefore, regardless of the use of naturally aspirated or supercharged models, foreign diesel engine manufacturers emphasize that the operating time of low load / no load should be reduced as much as possible, and the minimum load must not be lower than 25% -30% of the rated power of the unit.
The above are some of the precautions for the operation of the diesel generator set by Jiangsu Reed Power Equipment Co., Ltd.
