Five hazards of small load operation of high power generator set

1. Piston - cylinder liner seal is not good, oil up, into the combustion chamber of 300KW diesel generator set combustion, exhaust blue smoke;

2. For supercharged diesel engines, due to low load, no load, low supercharging pressure. The generator set is easy to lead to the decrease of the sealing effect of the supercharger oil seal (non-contact), oil into the pressurization chamber, along with the intake into the cylinder of the 300kW diesel generator set;

3. Up to the cylinder part of the oil involved in combustion, part of the oil can not completely burn, in the valve, inlet, piston top, piston ring and other places to form carbon, and part of the exhaust discharge. In this way, the 300KW diesel generator set cylinder liner exhaust duct will gradually accumulate oil, will also form carbon accumulation;

4. The oil accumulation in the supercharger chamber of the supercharger to a certain extent will leak out from the joint surface of the supercharger of the 300KW diesel generator set;

5.Long-term operation of 300KW diesel generator set with small load will lead to more serious wear of moving parts, deterioration of engine combustion environment and other consequences leading to advance overhaul period.

Therefore, foreign diesel engine manufacturers emphasize to reduce the low/no-load running time as much as possible, and stipulate that the small load should not be less than 25%-30% of the rated power of 300kW diesel generator set, regardless of the use of naturally aspirated type or supercharged type. Diesel generator long time full load operation, not only can improve its performance, find out hidden trouble, but also can avoid major communication accidents.

Jiangsu Meiao Power Technology Co., Ltd. is an important manufacturer of diesel generators. Us ao-generator set manufacturers mainly manufacture and selldiesel generator sets, the power of generator sets is 3-3000KW, mobile station is 24-600KW, Marine emergency diesel generator set 24-800KW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, silent speaker, mobile lighthouse, container, etc.) diesel generator Group at the same time engaged in generator set maintenance and generator set accessories after-sales service.
