1. Cold and antifreeze measures:
Add insulation materials: Wrap insulation materials such as cotton wool and clothing around the outside of the water pump to prevent it from freezing.
Drain the water pump: Drain the temporarily unused water pump and add water when in use to prevent the pump from freezing and causing the pump body to crack.
Maintain ambient temperature: Place the pump in a normal temperature environment to naturally defrost, or use hot water to defrost.
2. Selection of engine oil and fuel:
Choose the appropriate engine oil: In winter, use engine oil with lower viscosity to avoid an increase in viscosity at low temperatures, which can affect engine rotation.
Choose the appropriate fuel: Choose the appropriate diesel grade based on the lowest winter temperature in the local area to ensure that diesel does not solidify at low temperatures.
3. Use of antifreeze:
Choose the appropriate antifreeze: choose antifreeze with a freezing point 10 ℃ below the local minimum temperature to ensure that it will not freeze at low temperatures.
Regularly replace antifreeze: prevent antifreeze failure and ensure the normal operation of the cooling system.
4. Replacement of air filter and diesel filter:
Replace the air filter: In winter, the air is thin, dry, and cold, which increases the burden on the air filter. It needs to be replaced more frequently to ensure the cleanliness of the air before entering the engine.
Replace diesel filter element: prevent impurities in diesel from entering the fuel system and affecting the normal operation of the engine.
5. Preheating and low-speed operation:
Preheating: Before starting the generator set, it should be run at low speed for 3 to 5 minutes to increase the overall temperature of the machine.
Low speed operation: After starting, perform low-speed operation, check the working condition of the lubricating oil, and ensure normal operation before putting it back into use.
6. Inspection and maintenance of equipment:
Check the pump body and pipelines: Ensure that there are no leaks in the pump body and pipelines, and regularly check the fastening and sealing of each component.
Cleaning equipment: Regularly clean the surface and interior of the equipment to prevent carbon buildup and impurities from affecting its operation.
Through the above measures, the safe operation and extended service life of diesel engine water pumps in winter can be effectively ensured.
