Precautions for using Cummins generator set at low temperature

There are a lot of matters that need to be paid attention to during the use of Cummins generators. Do you know the precautions for using Cummins generators at low temperature? The following will introduce you in detail:


1. Do not use open flame to bake diesel generator oil pan. This will cause the oil in the oil pan to deteriorate, even burn, and reduce or completely lose its lubricating performance, which will aggravate the wear of the machine. In winter, a low freezing point oil should be used.


2. Light diesel oil with low freezing point and good ignition performance should be used in winter. Because the low temperature in winter will reduce the fluidity of the diesel, increase the viscosity, make it difficult to spray, cause poor atomization, and fail to fully burn, resulting in a decrease in the power of the diesel generator and waste. Generally, the freezing point of diesel should be 7-10 ° C lower than the local minimum gas in the current season.


3. After the diesel generator is turned off, the water temperature is below 60 ° C, the water is not hot, and then the flame is turned off. When the body is exposed to cold air at a high degree, it will shrink suddenly and cracks will appear. Drain the water thoroughly.


Fourth, the air filter cannot be removed for heating, causing wear of the piston cylinder and other components.


The temperature in winter is low, and the generator set is over cooled when it is working. Therefore, thermal insulation is the key to good use of diesel generators in winter. In northern areas, diesel generators used in winter should be equipped with cold-proof equipment such as insulation jackets and curtains, which often use the abnormal startup method of starting without water (starting first, then adding cooling water). This practice can cause serious damage to the machine and should not be used. Preheating method: first cover the thermal insulation cover on the water tank, open the drain valve, and continuously inject clean soft water at 60-70 ° C into the water tank. When the water flowing out of the drain valve feels hot, close the drain valve and fill the tank. Put in clean soft water at 90-100 ℃, and shake the crankshaft to make all moving parts properly lubricated before starting.
