All diesel generator parts in contact with all kinds of oil should be cleaned up after disassembly. Oil can be divided into two categories. A saponifiable oil is an oil that acts on a soap with a strong base, such as animal oil or vegetable oil.
The common failure forms of diesel generator engine parts include wear.deformation, fatigue fracture and corrosion. The damage of the genset refers to the phenomenon that the material gradually loses from one surface to the other when the object is in contact with each other and moves relative to each other, resulting in the operation of the surface.
In order to provide enough fresh air for diesel generator set operation, diesel engine intake should be arranged in the air circulation place outside the engine room. Diesel intake pipes for diesel generator set should be avoided as far as possible and the number of bends should be reduced, or use a large arc transition.
The uneven speed of diesel generator set is mostly caused by the abnormal resistance of the parts of the injection pump and governor and the slow response of the governor. Generally, there are two kinds of performance. One is a large swing, the voice is clearly identifiable, commonly known as gasp or tour car. The other is that the speed fluctuates in a small range, the sound is not easy to appear at low speed, which will lead to the diesel engine flameout.
