The maintenance of Yuchai generator set in low temperature winter mainly includes the following aspects to ensure the normal operation of the generator set and extend its service life:
1、 Yuchai generator set engine maintenance
Replace lubricating oil: Before changing seasons, replace the engine with lubricating oil suitable for low-temperature environments to ensure that the engine can operate normally at low temperatures.
Check antifreeze: Use high-quality antifreeze that meets the freezing point requirements, and regularly check the level and density of the antifreeze to prevent engine components from freezing and cracking due to low temperatures. At the same time, check the operation of the thermostat and water pump.
Preheating and warming up: Before starting the engine, perform a preheating operation to let the engine run at low speed and light load until it becomes hot. In addition, try to park the generator set indoors as much as possible to avoid engine freezing and cracking caused by outdoor storage.
2、 Yuchai Generator Set Fuel System Maintenance
Choose suitable diesel: Choose the appropriate diesel according to the ambient temperature, with a pour point 3-5 ℃ lower than the ambient temperature to ensure that it does not affect use due to solidification at the lowest temperature. Generally speaking, 0 # diesel can be used in winter in areas south of the Yangtze River, -35 ℃ diesel should be used in severe winter in Northeast, Northwest, and border areas, and -20 ℃ diesel should be used in severe winter in other areas.
Check the fuel filter: Regularly inspect and clean the fuel filter to prevent filter blockage caused by impurities in the fuel, which may affect fuel supply.
3、 Yuchai Generator Set Cooling System Maintenance
Check the cooling system: Ensure that the water pipes, water tanks, and other components in the cooling system are tightly connected and free of leaks. At the same time, check the operation of the cooling fan to ensure good heat dissipation.
Replace antifreeze: If ordinary water is used in the cooling system, it should be replaced with antifreeze before winter arrives to prevent components such as waterproof pipes and water tanks from freezing and cracking due to low temperatures.
4、 Yuchai Generator Set Electrical System Maintenance
Check the battery: Regularly check the battery of the generator set to ensure that the battery is fully charged and the electrode connections are tight. In low-temperature environments, special attention should be paid to keeping the battery warm and charging to avoid battery failure due to low temperatures.
Check the circuit: Regularly inspect the electrical system of the generator set, including lighting fixtures, speakers, warning lights, and other components, to ensure that the circuit connections are normal and there are no short circuits or open circuits.
5、 Yuchai Generator Set Other Maintenance Items
Check fasteners: Regularly inspect the fasteners of each component of the Yuchai generator set to ensure that bolts, nuts, and other fasteners are tightly connected and free of looseness.
Cleaning the unit: Regularly clean the casing, radiator, and other components of the generator set to prevent dust, oil, and other impurities from affecting the heat dissipation and normal operation of the unit.
Regular maintenance: According to the user manual and maintenance manual of the generator set, perform regular maintenance, including replacing filters, checking belt tension, adjusting valve clearances, and other items.
In summary, the maintenance and upkeep of the Yuchai generator set during low temperature winter cover various aspects such as the engine, fuel system, cooling system, electrical system, and others. Through comprehensive maintenance, it can be ensured that the generator set can operate normally in low temperature environments and extend its service life.
