Five Hazards Of Diesel Generators Running At Low Load

Apr. 07, 2022

We all know that the main purpose of low-load operation of diesel generators is to control preheating and prevent the occurrence of rapid wear and tear of diesel generators. The long-term low-load operation is undoubtedly an obstacle to the normal operation of diesel generators. Let us understand the five major hazards of wear and tear of moving parts during long-term low-load operation of diesel generators.

 

Diesel generator sets operate under a small load. With the continuation of the running time, the following five hazards will occur:

 

Hazard 1. The piston-cylinder liner is not well sealed, the oil runs up, enters the combustion chamber and burns, and the exhaust emits blue smoke.

 

Hazard 2. For a supercharged diesel engine, the boost pressure is low due to low load and no-load. It is easy to cause the sealing effect of the supercharger oil seal (non-contact type) to decrease, and the oil escapes into the supercharger chamber and enters the cylinder with the intake air.

 

Hazard 3. Part of the oil that goes up to the cylinder participates in the combustion, and part of the oil cannot be completely burned, forming carbon deposits on the valve, intake port, piston crown, piston ring, etc., and part of it is discharged with the exhaust. In this way, oil will gradually accumulate in the exhaust port of the cylinder liner, and carbon deposits will also be formed.

Hazard 4. The oil in the pressurized chamber of the supercharger accumulates to a certain extent, and it will leak from the joint surface of the supercharger.

 

Hazard 5. Long-term low-load operation will lead to more serious wear and tear of moving parts, deterioration of engine combustion environment, etc., which will lead to the consequences of early overhaul period.
