Weichai generators need to pay attention to the following items during winter maintenance:
1. Choosing the appropriate fuel and engine oil: In the low temperature environment of winter, the choice of diesel and engine oil is crucial. Diesel fuel suitable for local winter temperatures should be selected, usually with a pour point 7-10 ℃ lower than the minimum temperature, to ensure that it does not solidify in cold weather. Meanwhile, choose winter specific engine oil with lower viscosity to reduce friction and fuel consumption.
2. Selection and replacement of antifreeze: Antifreeze can prevent the cooling system from freezing at low temperatures, ensuring that the freezing point of antifreeze is 10 ℃ lower than the local minimum temperature, and regularly replacing antifreeze to prevent its failure.
3. Replacement of air and diesel filters: In winter, the air is thin, dry, and cold, and the ground dust increases. Therefore, air and diesel filters need to be replaced more frequently to maintain the cleanliness of the air and diesel, prevent impurities from entering the fuel system, and affect engine operation.
4. Preheating and low-speed operation: Preheat before starting and run at low speed for 3-5 minutes after starting to increase the overall temperature of the machine. Check the working condition of the lubricating oil to ensure the normal operation of the equipment.
5. Battery maintenance: Keep the battery pack terminals clean, regularly check the battery charging status, and ensure that the battery can still work normally at low temperatures.
6. Maintenance of cooling system: Regularly check the condition of the coolant to ensure it meets the requirements and prevent the cooling water from freezing and expanding at low temperatures, which can damage the cooling system.
7. Regular cleaning and maintenance: Regularly clean the dust and other dirt on the outer surface of the generator, keep the ventilation openings unobstructed, regularly replace the filter and oil, and ensure the normal operation of the generator set.
Through the above measures, the service life of Weichai generators in winter can be effectively extended, ensuring their stable operation.
