Risk Of Excessive Viscosity Of 200KW Diesel Generator Set Oil

Apr. 13, 2022

The generator may not be used often in our daily life, but it is inseparable in some enterprises and institutions. Once the circuit is interrupted, it will cause a lot of inconvenience. In this article, a professional diesel generator manufacturer, Jiangsu Starlight Electricity Equipments Co.,Ltd., will introduce the viscosity of oil to you.


Risk of Excessive Viscosity of 200KW Diesel Generator Set Oil:


1. The engine is difficult to start at low temperature. When the engine is started at a low temperature, the oiling is too slow. Although the oil pressure is high, the amount of oil passing through is not much, and the pumpability of the oil is poor, which increases the amount of wear during the period from the start of the engine to the time when the oil enters the friction surface.


2. The cleaning effect is poor, the viscosity of the oil is high, the circulation speed of the oil is slow, and the number of times passing through the filter is reduced, and the worn metal grinding, carbon particles, dust and other impurities cannot be taken away from the friction surface in time.


3. The cooling effect is poor, the oil viscosity is large, the fluidity is poor, the circulation speed is slow, and the speed of the heat taken away from the friction surface is also slow, which is easy to overheat the engine.


4. If the residual carbon is high and the viscosity is too large, the residual carbon particles will be large and the freezing point will be high, which will easily block the oil circuit. The danger of oil viscosity is too small: the oil film is not enough, it is easy to be damaged, and it is not easy to form an oil film of sufficient thickness on the high temperature friction surface. The bearing capacity of the oil film is poor, and it is easy to be damaged under the load, so that the parts cannot be lubricated normally, the wear is increased, and the sealing is not good.


Choose high-quality base oil, high-performance additives, and suitable formula. In special cases, a product with a larger quality affluence or a high-quality grade is provided. Different brands of diesel generator sets have special oil.

The viscosity of the oil determines the internal friction resistance of the oil when it flows. The oil viscosity is related to the engine temperature. When the engine temperature is low, the oil viscosity is high. On the contrary, when the engine temperature is high, the oil viscosity is small. When the oil viscosity is large, the fluidity is poor, but the sealing performance is good, and the leakage is small. If the oil viscosity exceeds the specified value, the oil flow resistance in the lubrication system will increase, and the pressure will increase at the same time. It can be seen from this that when the engine temperature is low or the viscosity of the oil itself is high, for example, some users choose oil with high viscosity in summer due to improper selection of oil grades in winter, the pressure of the oil will increase and will damage its lifespan.


Jiangsu Starlight Electricity Equipments Co.,Ltd. reminds that users should pay close attention to the condition of the oil when operating the diesel generator set, and conduct all-round inspections of the generator set to ensure that the quality oil is provided for the generator set and promote the normal operation of the generator set.
