Four things to pay attention to when using diesel generator sets in winter

May 17, 2022
Diesel generator set is an independent power generation equipment. It is a power machine that uses diesel as fuel and uses diesel engine as the driving force to drive generators to generate electricity. In winter, diesel generator sets also need to be adjusted accordingly, especially for outdoor use. Pay attention to the weather changes at any time. In addition, users need to pay attention to the following four items when using diesel generator sets in winter:
1. Pay attention to temperature changes and release the cooling water in time. Diesel generator sets are often operated outdoors, and special attention should be paid to temperature changes in winter. If the temperature is lower than 4 degrees, the cooling water in the cooling water tank of the diesel engine should be drained in time to ensure that the cooling water will not solidify in the cooling water tank. If the temperature is too low, the cooling water will expand during the solidification process, causing the cooling water tank to burst and damage.
2. Change the air filter frequently. The air filter element filters out the impurities in the air and ensures the normal operation of the diesel engine cylinder. In winter, the surface wind speed is relatively high, the air flow is strong and there are many impurities. Frequent replacement of the air filter will reduce the impurities entering the cylinder and prolong the service life and safety of the diesel generator set.
3. Preheat in advance and start slowly. When the diesel generator is started in winter, the temperature of the air sucked into the cylinder is low, and it is difficult for the piston to compress the gas to reach the temperature of diesel spontaneous combustion. Therefore, before starting the diesel engine, corresponding auxiliary measures should be taken to increase the temperature of the diesel engine body. After the diesel engine is started, it should run at low speed for 3-5 minutes. After the temperature of the diesel engine of the generator set increases, check the working condition of the lubricating oil. After the inspection is normal, the diesel generator set can be put into normal operation.
4. Choose low-viscosity oil. When choosing oil for diesel generator sets in winter, try to choose oil with low viscosity. After the temperature drops sharply, the viscosity of the oil will increase, which may be greatly affected during cold start, causing the generator set to be difficult to start.
