Diesel generator sets in the winter use and maintenance should pay attention to matters:
 
One, bogey waterproof or too cold water. Diesel generator set to idle before the idle operation, to be cooling water temperature dropped to below 60 ¡æ, the water is not hot, and then turn     off the fire. If the cooling water is released too early, the diesel generator body suddenly suffers from cold air when the temperature is high, and the crack occurs. Waterproof diesel engine should be the body of the residual water completely discharged, while its icing swelling, so that the body cracked.
 
Second, bogey choose fuel. The low temperature in winter makes the flowability of diesel oil worse, the viscosity increases, is not easy to spray, resulting in bad atomization, combustion deterioration, resulting in diesel generator sets of power and economic performance. Gu winter should use low pour point and good ignition performance light diesel oil. General requirements of the diesel generator set of condensate should be lower than the local minimum temperature of 7-10 ¡æ.
 
Three, bogey with open fire to help start. Can not remove the air filter, with cotton yarn dipped in diesel ignition made after the ignition into the intake pipe to start combustion. This will be in the process of starting, the outside of the dust will be without direct filtering inhalation of the cylinder, resulting in piston, cylinder and other parts of the abnormal wear and tear, but also cause heavy work of diesel generators, damage to the machine.

Four, bogey with open fire baking oil pan. So as to avoid the oil within the oil pan deterioration, or even charred, reduce the performance or complete loss of lubrication, thereby increasing the machine wear. Winter should use low pour point of oil, start the machine can be used outside the bath heating method to improve the oil temperature.
 
Five, bogey start method improper. In winter, some drivers are able to start diesel engines quickly, and the plant uses a non-normal start-up method. This will cause serious damage to the machine and should be prohibited. The correct method of preheating is to cover the insulation in the water tank, open the drain valve, continuous into the tank filled with 60-70 ¡æ clean soft water, hand touch the water outflow of water is hot feeling, and then turn off the valve, The tank is filled with 90-100 ° C clean water, and shake the crankshaft, so that the moving parts are properly pre-lubricated, and then start again.
 
Six, diesel generating units bogey low temperature load operation. Diesel generator sets start fire, some drivers can not wait to immediately put the load operation. Fire near the diesel generator due to the body temperature is low, oil viscosity, oil is not easy to fill the friction surface of the movement, will cause serious wear and tear machine. In addition, the plunger springs, valve springs and injector springs are also easily broken due to "cold brittle". So the winter diesel generating units start the fire, the low speed should be idle for a few minutes, and other cooling water temperature reached 60 ¡æ, and then put the load operation.
 
Seven, bogey do not pay attention to the body insulation. Low temperature in winter, easy to make diesel generator work when the cooling too much. So the insulation is the key to use diesel generators in winter. In the northern region, the use of diesel generators in winter should be equipped with insulation and insulation curtains and other cold equipment, and other thermostats on the diesel generator sets play an important role in warming.
