Diesel Generator Tech

Don't know how to select engine fuel, lubrication oil and coolant? Don't worry, this post will guide you to select the right one. ① Fuel The fuel should be selected according to ambient temperature. The selection should comply with light  Diesel  Fuel(GB252 choice fuel and first class fuel). Ambient temperature ② Oil Lubricating oil should be selected according to the ambient condition. The class of oil should not be lower than CD class of GB11122–1997 Ambient temperature ③ Coolant The coolant should be anti-freezing, especially when the engine is used in the plateau and in cold weather(below 0℃). It is good for the engine. The most used anti-freezer is glycol-water, which is a mixture of glycol and water( soft water is best. such as well water, spring water or other hard water, it should be mixed 2g tri-sodium phosphate with one liter water for softing). Selection of different proportionality coolant should vary with the ambient temperature. ...

The use of the coolant in the cooling system is to prevent corrosion and formation of scale in the cooling circuit and within the engine. We should never use water alone, as a coolant in diesel engines since water itself can be corrosive at high operating temperatures. The use of coolant in diesel generator solves the problems of poor cooling and high temperature of the diesel generating set. Usually, we should replace the cooling liquid every one and a half years to two years. The standard replacement cycle of the cooling liquid will be very helpful for the genset protection. It can form a protective film on the surface of cylinder sleeve of the generator set so as to prevent the occurrence of cavitation and reducing wear and corrosion, which can prolong the maintenance intervals of the   genset   and reduce the maintenance cost. On the contrary, non-replacement for a long time, it will definitely reduce the using effects. So what problems should be paid attention to i...
