The hazards of running small loads in diesel generator sets for long periods of time

July 27, 2022
Users who have diesel generator sets at home know what it is for, but are unaware of some of its matters, users have always had the perception that the smaller the load of diesel generators used the more beneficial. In fact, this is wrong, diesel generator sets run under a small load for a long time, the longer the more harmful. The following silent type generator rental manufacturers Yatong Xiaobian here to tell you the smaller the load of diesel generator set use will have what harm:.
1, the piston: If the load is too small, the piston cylinder liner seal is not solid, resulting in oil up, into the combustion chamber combustion, exhaust blue smoke, pollution of the air.
2, for supercharged diesel generator sets, due to low load, no load, low boost pressure. Easily lead to the supercharger oil seal (non-contact) sealing effect is reduced, the oil fled into the boost chamber, with the intake air into the cylinder.
3, up to the cylinder part of the oil involved in combustion, part of the oil can not be completely burned, in the valve, intake, piston top, piston ring and other places to form carbon, and part of the exhaust with the exhaust. In this way, oil will gradually accumulate in the exhaust channel of the cylinder liner, and carbon will also be formed.
4, the supercharger oil accumulation to a certain extent, it will leak out from the supercharger at the combination of surface.
5, long-term small load operation, will more seriously lead to increased wear of moving parts, engine combustion environment deterioration and other consequences that lead to early overhaul period.
Therefore, we recommend that whether the use of naturally aspirated or supercharged models are stressed that low load / no load running time should be minimized, and the minimum load should not be less than 25%-30% of the rated power of the unit.
Long-term full-load operation of diesel generator sets can not only improve their performance and identify safety hazards, but also avoid major communication accidents.
