Monthly maintenance:
Clean the outer surface of the unit to maintain a clean appearance.
Check if the speed control rod is flexible and lubricate all connection points.
Replace the cooling water, measure the pH value (normal value is 7.5-9), and make records.
Check the tension of the fan belt and charger belt, and adjust them if necessary.
Cooperate with the emergency power generation test for electrical work, check whether the readings of various instruments, temperature, and loudness are normal during the operation of the diesel engine, and make operation records.
Quarterly maintenance:
Check the air flow resistance indicator and clean the air filter when it displays red.
Release the accumulated diesel water and clean the diesel filter.
Check the lubrication fan pulley and belt tensioner bearing.
Check the lubricating oil level of the overspeed mechanical protection device and add oil if it is insufficient.
Check the tightening condition of the main external connecting bolts.
Annual maintenance:
Cooperate with electricians to carry out parallel load operation and check the operation status.
Simulate the performance of each protective device in the test.
Measure the axis, open the gear, and keep records.
Remove the inspection cover and observe the condition of the shaft and cylinder.
Clean the cooling system.
Check the quality of the engine oil and replace it if necessary.
Clean the diesel filter.
Clean the oil filter.
Specific content and precautions for maintenance:
Clean the surface of the generator: Regularly remove dust and dirt from the surface of the generator to keep its appearance clean. Use a soft cloth or brush for cleaning and avoid using cleaning agents containing chemicals.
Check the fuel system and lubricating oil system: Check the cleanliness and adequacy of the fuel system and lubricating oil system to ensure that the quality of the fuel and lubricating oil meets the requirements. If necessary, replace the fuel filter and lubricating oil filter, clean the fuel tank and oil passage.
Check the cooling system: Check if the coolant in the cooling system is sufficient and clean, and replace the coolant if necessary. At the same time, check the working condition of components such as water pumps and radiators to ensure their normal operation.
Check the electrical system: Check whether the cables, wiring terminals, and other components of the electrical system are loose or aging, and tighten or replace them if necessary. At the same time, check whether the output voltage, frequency and other parameters of the generator set are normal.
Check mechanical components: Check the wear of mechanical components such as bearings and gears of the generator set, and repair or replace them if necessary. At the same time, check if the fasteners of the unit are loose and tighten them if necessary.
By following these steps and precautions, it is possible to ensure the normal operation of the Huaquan generator and extend its service life.
