Harm of excessive oil viscosity to Cummins diesel generator set

Oil viscosity is an important factor affecting the performance and life of diesel generator set. If the oil viscosity is too large, the engine friction resistance of the diesel generator set increases, and the pump delivery performance is poor at the same time, and the local lubrication is not available, it will affect the service life of the generator set. Here by the United States and Austria power to introduce the diesel generator oil viscosity is too large harm.

How to judge the oil viscosity of diesel generator set is too large? It can be detected by observing the oil pressure gauge. When the oil viscosity is large, the pressure gauge shows that the oil pressure value is too high and exceeds the specified value. The size of oil viscosity determines the size of internal friction resistance of oil flow. The size of oil viscosity and engine temperature, engine temperature is low, oil viscosity;

Conversely, when the engine temperature is high, the oil viscosity is small. When the oil viscosity is large, the fluidity is poor but the sealing is good and the leakage is less. If the oil viscosity exceeds the specified value, the oil flow resistance in the lubrication system will increase, and the pressure will increase. It can be seen that when the engine temperature is low or the oil itself is high in viscosity, for example, some users choose the oil with high viscosity in summer in winter due to the improper selection of the oil brand, the pressure of the oil will increase, and the diesel generator set will be started at this time, which will damage its life.

It is worth noting that the improper adjustment of the pressure limiting valve, the blockage of the filter, and the clearance of the pressure lubrication part is too small may also be the reason for the high pressure. At this time, the operator needs to check one by one, carry out timely maintenance or parts replacement, so as to ensure the normal operation of the diesel generator set.

Jiangsu Meiao Power Technology Co., Ltd. is an important manufacturer of diesel generators. Us ao-generator set manufacturers mainly manufacture and sell diesel 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.
