Matters needing attention in the use and maintenance of diesel generator sets in winter:

I. avoid waterproof, premature or no cooling water. The diesel generator sets to idle at the beginning of flameout before the cooling water temperature drops below 60 degrees, the water is not hot, and then flameout waterproof. If the cooling water is released too early, the diesel generator set will suddenly shrink and crack when it is attacked by cold air when the temperature is higher. When waterproof, the residual water in the diesel generator set should be completely discharged, and the side of the diesel generator will be frozen and inflated, which will cause the body to crack.

Two, avoid arbitrary choice of fuel. The liquidity of the diesel low winter temperature variation, the viscosity increases, is not easy to spread, resulting in poor atomization, combustion deterioration, resulting in a decline in the power and economy performance of the diesel engine generator. Gu winter should choose low pour point of light diesel oil combustion and good performance. General requirements of diesel generator set point should be lower than the local minimum seasonal temperature 7-10.

Three, avoid using flame combustion start. Can not remove the air filter, cotton dipped in diesel fuel, lit into a fire, placed in the intake pipe, the implementation of combustion support start. So in the process of starting the outside air with dust will not filtered and directly into the cylinder, causing abnormal wear of the piston and the cylinder and other parts of the work, will cause the diesel generator rough machine damage.

Four. Avoid baking the oil pan with open flame. In order to avoid the oil in the oil tank deterioration, and even burned, lubrication performance decreased or completely lost, thereby increasing machine wear. Winter should choose low pour point oil, starting method can be used when the machine water heating to improve oil temperature.

Five, avoid starting improper. In winter, some drivers are able to start the diesel engine quickly, and the factory starts the abnormal starting without water. This will cause serious damage to the machine and shall be prohibited. The correct way is to preheat the insulation cover on the water tank, open drain valve, continuous injection of 60-70 C clean water to the water tank, touch the drain valve out of the water is hot, and then close the drain valve, 90-100 C to clean soft water poured into the water tank, and the crank shaft, the movement a proper pre lubrication, and then re start.

Six 、 diesel generator set avoid low temperature load operation. After the diesel generator set fire, some drivers are eager to put it into operation immediately. The diesel generator set on fire will cause serious wear and tear of the engine because of its low temperature and high viscosity. In addition, the plunger spring, the valve spring and the injector spring are easy to break due to "cold shortness". Therefore, the diesel generator set should be put into operation at low or medium speed for a few minutes, when the cooling water temperature reaches 60 degrees centigrade.

Seven, do not pay attention to body heat preservation. The low temperature in winter makes it easy to cool down when the diesel generator sets to work. Therefore, insulation is the key to use diesel generator set in winter. In the northern areas, the diesel generator sets used in winter are equipped with cold insulation equipment, such as thermal insulation sleeves and thermal curtain. In addition, thermostat plays an important role in the temperature rise of diesel generating set.
