Diesel generator set is a combination of diesel engine and generator. The diesel engine drives the generator to generate electricity. However, both diesel engine and generator need maintenance and cold protection in this snowy winter. How to carry out the maintenance of diesel generator set in winter?
1. Replace the fuel
Nowadays, diesel oil on the market has different applicable temperatures according to different brands. Therefore, before the advent of winter, we should first understand how low the local winter temperature was in previous years, and then select diesel oil with an applicable temperature lower than 3 to 5 ℃, which can be selected as needed.
2. Use antifreeze
Antifreeze can make diesel generator set work effectively in winter. Generally, antifreeze with freezing point 10 ℃ lower than local Z low temperature shall be selected. Antifreeze generally has color, which can be found in time when the leakage is found. Once the leakage is found, wipe it dry, check the leakage and repair it in time. There is also the regular replacement of antifreeze to prevent its failure.
3. Change the oil
The engine oil at normal temperature is different from that at colder temperature. The viscosity and friction of the engine oil at normal temperature will increase in cold winter, which will affect the rotation of the engine and increase the fuel consumption. Therefore, it is necessary to replace the special engine oil in winter. However, winter engine oil cannot be used under normal temperature, because the engine oil used in winter under normal temperature may fail, which will cause equipment failure.
4. Replace the filter element
In winter, the air is thin, dry and cold, and the ground dust is scattered in the air by mechanical vibration. Therefore, the air filter element of diesel generator set is very important and needs to be replaced more frequently. Otherwise, the dust in the air will not only affect the purity and combustion of oil, but also enter the cylinder wear equipment.
5. Preheating work
Just like the automobile, when the external air is cold, the diesel generator set needs to be started at a low speed for 3 to 5 minutes to check after the temperature of the whole machine is increased. It can be used normally only after everything is normal. Otherwise, after the cold air enters the cylinder, the compressed gas is difficult to reach the natural temperature of diesel; At the same time, sudden speed-up operation shall be reduced during operation, otherwise the service life of valve assembly will be affected.
What are cold and antifreeze measures for diesel generator set?
1. During the maintenance of diesel generator set in winter, the ventilation and air conditioning of facilities and equipment such as distribution room and control room shall be normal, and maintenance and overhaul shall be carried out in advance;
2. Exposed equipment and pipeline circuits leading to the outside of the machine room need to be covered with insulation cotton, grass cotton, cotton rope and other covering insulation measures;
3. Check the sealing degree of the doors and windows of the machine room to ensure that there is no cold wind and snow blowing in the machine room in the weather of wind and snow cooling, and ensure that the indoor temperature will not leak before the equipment works normally.
4. The heater shall be put into operation to increase the equipment temperature, and the air start can be carried out only after the temperature of motor cylinder and components is increased to the standard temperature.
5. It is recommended that the diesel genset located outdoors be covered with insulation shed to achieve the effect of cold and antifreeze. If conditions do not permit, it is not allowed to bake the equipment with open fire.
