The weather is cold in winter, so the maintenance of diesel generator sets in winter is particularly important
1. After the diesel engine runs in winter, if it is parked in the open air, pay attention to the weather changes at any time. When the temperature is lower than 4 degrees, the cooling water in the cooling water tank of the diesel engine should be released, because the volume of water changes greatly. When changing from a liquid to a solid, the increased volume and expansion can damage the cooling tank radiator.
2. Choose a suitable antifreeze, replace the antifreeze regularly, and prevent leakage when adding.
3. In winter, due to the poor working environment of the diesel engine, it is necessary to change the air filter element frequently at this time. Due to the high requirements for the air filter element and the diesel filter element in cold weather, if it is not replaced in time, it will increase the wear of the engine and affect the life of the diesel engine.
4. When choosing oil for diesel engines in winter, you should try to choose oil with a thinner viscosity.
5. When the diesel engine is started in winter, the temperature of the air inhaled in the cylinder is low, and it is difficult for the piston to compress the gas to reach the natural temperature of the diesel. Therefore, before starting the diesel engine, corresponding auxiliary methods should be used to increase the temperature of the diesel engine body.
6. The diesel engine should run at low speed for 3-5 minutes after starting, in order to increase the temperature of the diesel engine, check the working condition of the lubricating oil, and then put it into normal operation after the inspection is normal. During the operation of the diesel engine, try to reduce the sudden acceleration of the speed to the maximum operation, otherwise the service life of the valve assembly will be affected for a long time.
