Hazards of Cold - Starting School Silent Diesel Generators

Some operators are careless at work. After starting the generator set, they rev up the engine violently. Improper operation causes the temperature of various components to rise rapidly shortly after starting. Improper operation can easily lead to malfunctions in the generator set.

When cold - starting the engine, especially in winter, since there is little oil on the piston rings and cylinder walls, the sealing effect is poor. There may be a phenomenon of repeated starting but failure to ignite and run. This is because the oil pump fails to supply enough oil, and the friction surfaces of the machine lack proper lubrication due to insufficient oil, resulting in severe wear. In severe cases, problems such as cylinder scoring and bearing burnout may occur. Sometimes, for school - use silent diesel generator sets, heavy cylinder wear can seriously affect the cylinder's sealing performance, making starting even more difficult. In this regard, the injectors can be removed, and 30 - 40 ml of oil can be added to each cylinder to enhance the cylinder's sealing performance and increase the pressure during compression. The correct starting method is that after a cold start of the diesel engine, it should run at idle speed to warm up. It should not be loaded until the oil temperature reaches above 40°C. When starting the machine, it should be in a low - gear position, and it should drive for a certain distance in each gear until the oil temperature is normal and the oil supply is sufficient before switching to normal driving.

It is wrong to rev up the engine violently after a cold start of the diesel engine. If the engine is revved up violently, the rotational speed of the diesel generator will increase sharply, causing severe wear on some friction surfaces of the machine due to dry friction. In addition, when revving up the engine, the piston, connecting rod, and crankshaft are subject to large force changes, which cause severe impacts and can easily damage the machine parts.

That's all for the knowledge about the hazards of cold - starting school - use silent diesel generator sets. The overhaul and maintenance of diesel generator sets should be entrusted to professional diesel generator manufacturers, especially for some important units and departments. The diesel engines used in the diesel generator sets produced by Guangxi Dingbo Power are all genuine and directly supplied by the original manufacturers, with a guarantee of authenticity and a promise of ten - fold compensation for any fakes.
