Diesel generator set It is an indispensable temporary backup power generation equipment for some manufacturers. Diesel generators are more troublesome than oil-free ones. As we all know, the oil of diesel generator set has a great lubrication effect on the generator set, such as the lubrication of bearings, gears, rotors and other key mechanical parts; If the diesel generator runs for a long time, impurities such as oil scale and other dust in the oil circuit system will pass through the oil drum and oil filter, so that the diesel engine can prevent coking and ensure the normal operation quality of the generator set.
The influence of unqualified oil on engine of diesel generator set
However, in actual use, many users use unqualified oil, which leads to high temperature, carbon formation, coking, no power generation, spontaneous combustion and so on.
Why does substandard diesel generator oil cause so many problems in the generator set? Because irregular diesel engine oil oxidation decomposition at high temperature, carbonization; When it reaches the ignition point, it is prone to spontaneous combustion and other accidents.
Therefore, brand diesel generator sets sold on the market are equipped with special engine oil, which can ensure the following performance of the unit:
Diesel engine parts have good fluidity at low temperature;
Good oxidation stability and thermal stability;
Excellent emulsion resistance, hydrolysis resistance and corrosion resistance;
Prolong the life of the main engine, fast water separation, prevent the failure of diesel generator set due to corrosion, reduce fuel consumption.
Therefore, when choosing diesel generator oil, the following points should be paid attention to:
① High oil, not easy to oxidize thickening.
② It is better to use special oil (or national standard CF diesel generator oil grade above) to ensure the normal operation of the generator set.
③ Appropriate viscosity (high pressure, high temperature, high oil viscosity).
(4) If refueling is too much, in addition to wasting lubricating oil, it is easy to make the exhaust valve carbon deposit and diesel engine weak output, thus affecting the service life and efficiency of parts; If the oil is too little, the parts will wear and burn due to poor lubrication. Add diesel engine oil, pay attention to the engine oil gauge, do not add too much or too little.
⑤ Low carbon content, high flash point, not easy to saponify.
In addition to the correct selection of engine oil in the generator set, it is more meaningful that the waste heat recovery system of diesel engine can be used to help the factory save energy and reduce emissions.
“Diesel generator waste heat recovery system” can not only reduce the oil temperature of the generator set, greatly extend the service time of the generator set, improve the performance of the diesel generator set, extend the service life of the generator set, but also convert the waste heat of the diesel generator into free factory hot water, industrial production heat, food production hot water, cleaning pool heating, winter heating, etc. Continue to save energy consumption for enterprises, reduce the loss of diesel generators, save a lot of costs.
