Winter is coming. For the majority of diesel generator set users of Woda Power, due to the low temperature, dry air and strong wind in winter, don't forget to do winter maintenance for your diesel generator! In this way, the excellent performance of the diesel generator set can be ensured and the service time can be longer. We will give some suggestions on the winter maintenance of diesel generators in winter.
Diesel replacement
In general, the freezing point of the diesel oil used should be 3-5°C lower than the seasonal low temperature to ensure that the low temperature will not affect the use due to solidification. usually:
5# diesel is suitable for use when the temperature is above 8℃;
0# diesel is suitable for use when the temperature is between 8°C and 4°C;
-10# diesel oil is suitable for use when the temperature is between 4℃ and -5℃;
-20# diesel is suitable for use when the temperature is -5℃ to -14℃;
-35# diesel is suitable for use when the temperature is -14℃ to -29℃;
-50# diesel oil is suitable for use when the temperature is between -29℃ to -44℃ or lower.
Choose the right antifreeze
Change the antifreeze regularly and prevent leaks when adding. Antifreeze is available in red, green and blue. It is easy to find out when it leaks. Once it is found, it is necessary to wipe up the leakage and check the leak to select an antifreeze with a suitable freezing point. Generally speaking, the freezing point of the selected antifreeze should be lower than The local low temperature is 10 ℃, and there is some surplus to prevent the sudden drop in temperature at certain times.
Choose a low viscosity oil
After the temperature drops sharply, the viscosity of the oil will increase, which may be greatly affected during cold start. It is difficult to start and the engine is difficult to rotate. Therefore, when choosing oil for diesel generator sets in winter, it is recommended to replace the oil with lower viscosity.
Replace air filter
Due to the high requirements for air filter elements and diesel filter elements in cold weather, if they are not replaced in time, the wear of the engine will increase and the service life of the diesel generator set will be affected. Therefore, it is necessary to replace the air filter frequently to reduce the probability of impurities entering the cylinder and prolong the service life and safety of the diesel generator set.
Drain the cooling water in time
In winter, special attention should be paid to the change of temperature. If the temperature is lower than 4 degrees, the cooling water in the cooling water tank of the diesel engine should be released in time, otherwise the cooling water will expand during the solidification process, which will cause the cooling water tank to burst and damage.
Warm up in advance, start slowly
After the diesel generator set is started in winter, it should run at low speed for 3-5 minutes in order to increase the temperature of the whole machine, check the working condition of the lubricating oil, and then put it into normal operation after the inspection is normal. The diesel generator set should try to reduce the sudden acceleration of the speed or the large operation of the accelerator during operation, otherwise the service life of the valve assembly will be affected for a long time.
The above are some strategies for the maintenance of diesel generators in winter compiled by Woda Power. I hope that the majority of generator set users will take winter protective measures in time!
