Several Effective Cooling Methods for Diesel Generator

With the arrival of the summer vacation, the temperature in many places once soared to 40°C. Such high temperature weather is not a good thing for diesel generator sets. We know that the operation of diesel generator sets requires a certain working environment, and the temperature is one of the more important points. For diesel generator sets, it is very important to ensure good ventilation and cooling effect in summer. Otherwise, the diesel engine is prone to overheating, which will reduce the power, economy and work reliability of the diesel generator set. The article Dingbo Power will talk to you about several effective cooling methods.

There are two common cooling methods for diesel generator sets, air cooling and water cooling. The principle is the same as that of the engine. The temperature in the environment is taken away by this fast heating and strong fluidity substance, thereby controlling the working environment. temperature. The water cooling mainly works by the water circulation system. The water pump draws the cold water into the cold water pipeline, and the heat is taken away by the water flow wrapped in the water cooling pipeline on the equipment. Air cooling is generally a ventilation system installed in the generator room to achieve the purpose of controlling the indoor temperature through the exchange of cold and hot air.

There are four common ventilation systems:

1. Usual ventilation system: for ventilation of the generator room, it is usually the ventilation volume of 10~15 times of air changes. Only the exhaust fan can be set up: if there is gas in the water supply and drainage to extinguish the fire, this system will also be responsible for the exhaust after the fire is extinguished. wind system.

2. The Generator processes air intake and exhaust system: The motor itself has a large exhaust duct, which is provided by the generator. We can cooperate with the air well. At the same time, the air intake system is designed to supplement the exhaust air volume and the generator set. Combustion air volume (electrical capital raising), set up blower, this system has a large air volume.

3. Generator exhaust gas system: It involves environmental protection issues, usually called exhaust pipe. The diesel generator comes with it. There is also a special well for this system in the electrical standard atlas. It's hard to have so many vacancies. Most of them are discharged outdoors by the generator exhaust shaft.

4. Oil storage room exhaust system: It can be used in combination with the usual ventilation system. At this time, the branch pipe leading to the oil storage room is equipped with a check valve and a fire damper; a separate system can also be used, and an explosion-proof fan can be used.

Common diesel engine water cooling methods:

Keep the cooling system working properly

1. Scale removal Scale often has a greater impact on the cooling system. Therefore, it is necessary to strengthen the cleaning of the cooling system to ensure the heat dissipation effect of the diesel engine. Keeping the cooling system clean can effectively improve the heat dissipation efficiency of the diesel generator set. Provide a good operating environment.

2. Keep the radiator clean. The water radiator should be dredged and flushed. If the outside of the radiator is stained with dirt, oil, or the heat sink is deformed due to collision, the heat dissipation effect of the generator set will be affected. If this is found during use, it should be cleaned or trimmed in time.

3. Keep the coolant sufficient When the diesel generator set is in a cold state, the coolant level should be located between the high and low marks of the water tank, neither too high nor too low, otherwise it will affect the cooling effect of the generator set.

4. Ensure the tightness of the drive belt;

5. Also pay attention to the working condition of the thermostat, the sealing condition of the cooling system and the ventilation condition of the vents on the radiator cover, and do irregular inspections.

6. Avoid overloading the diesel generator set

If the diesel generator set is overloaded for a long time, the cooling effect of the coolant will be deteriorated, resulting in the high temperature of the generator set and affecting the normal use. In addition, if the fan tape is too loose, the speed of the water pump will be too low, which will affect the circulation of the coolant and accelerate the wear of the tape; if the tape is too tight, the water pump bearing will be worn. Therefore, the fan tape should be kept moderately tight, and at the same time, it should not be stained with oil.

In the hot summer, once the cooling of the diesel generator set is not done well, it is likely to cause the diesel generator set to malfunction, and the stability of its operation cannot be guaranteed. Therefore, the cooling problem must not be sloppy. If you are interested in purchasing diesel generator sets, you can contact us at any time by E-mail: dingbo@dieselgeneratortech.com.
