Cummins generator set in the case of low temperature should pay attention to:
First, can not use open fire to bake diesel generator oil pan. This will make the oil in the oil pan deterioration, or even scorched, lubrication performance is reduced or completely lost, thereby exacerbating the wear of the machine, winter should choose low freezing point oil.
Two, light diesel oil with low freezing point and good ignition performance should be selected in winter. Because the low temperature in winter will reduce the liquidity of diesel oil, increase the viscosity, not easy to spray, will cause poor atomization, can not fully combustion, resulting in the decline of the power of diesel generators, resulting in waste. Generally, the freezing point of diesel oil should be 7-10℃ lower than the local low gas in the current season.
Three, after the diesel generator set is extinguished, the water temperature is below 60℃, the water is not hot, and then the fire is discharged. The body in a higher degree of sudden cold air invasion will produce sudden contraction, crack. The water should be drained thoroughly.
Four, the air filter can not be removed to heat, resulting in the wear of piston cylinder and other components.
In winter, the temperature is low, and the generator unit is excessively cooled when working. Therefore, heat preservation is the key to use diesel generator well in winter. In the northern region, the diesel generators used in winter should be equipped with thermal insulation sleeve and thermal insulation curtain and other cold protection equipment. Usually, the abnormal starting method without water (start first, then add cooling water) is adopted. This practice can cause serious damage to the machine and should be prohibited. Preheating method: heat preservation quilt on the tank first, open the drain valve, the tank clean soft water continuous injection of 60-70 ℃, with the hand touch water drain valve flow of water when feel hot, and then close the drain valve and to clean soft water tank into the 90-100 ℃, and turn the crankshaft, make each moving part properly lubricated beforehand, and then start again.
