What are the maintenance levels of diesel generator sets?

There are four levels of maintenance methods for generator sets:

Class A detailed maintenance method.

1. Daily maintenance:

2. Check the diesel generator set: oil level, coolant level.

3. Check whether the diesel generator set is damaged or leaked, and whether the belt is loose or worn.

2. Weekly maintenance:

1. Repeat the daily inspection of Class A diesel generator sets.

2. Check the air filter, clean or replace the air filter core.

3. Release the water or sediment in the fuel tank and fuel filter.

4. Check the water filter.

5. Check the starting battery.

6. Start the diesel generator set and check whether there is any impact.

Class B detailed maintenance method.

1. Repeat the daily inspection of Class A diesel generator set and weekly inspection of diesel generator set.

2. Change the oil of the diesel generator set. (The oil change interval is 250 hours or one month) 3. Change the oil filter. (The oil filter element replacement cycle is 250 hours or one month) 4. Replace the fuel filter element.

The replacement cycle is 250 hours or one month) 5. Change the coolant or check the coolant. (The water filter element is replaced by 250-300 hours, and the cooling system is filled with supplemental coolant DCA).

6. Clean or replace the air filter. (The air filter replacement interval is 500-600 hours) C-level detailed maintenance method.

1. Replace the diesel filter, oil filter, water filter, and replace the water and oil in the water tank.

2. Adjust the tension of the fan belt.

3. Check the supercharger.

4. Dismantle, inspect and clean PT pump and actuator.

5. Disassemble the rocker chamber cover, check the T-shaped pressure plate, valve guide and intake and exhaust valves.

6. Adjust the lift of the nozzle; Adjust the valve clearance.

7. Check the charging generator.

8. Check the radiator of the water tank and clean the external radiator of the water tank.

9. Add water tank treasure to the water tank and clean the inside of the water tank.

10) Check the diesel engine sensor and connecting wires.

11) Check the diesel engine instrument box.

Level D detailed maintenance method.

2. Clean or replace the air filter.

3. Disassemble the rocker chamber cover, check the valve guide and T-shaped pressure plate.

4. Check and adjust the valve clearance.

5. Replace the upper and lower pads of the rocker arm chamber.

The maintenance of the diesel generator set is very important, as follows: Daily inspection During the daily inspection, it is necessary to check the outside of the generator set, whether there is a leakage of electrolyte in the battery, and check the voltage value of the battery and the temperature of the jacket water. In addition, it is necessary to check whether the heater of the jacket water, the charger of the battery, and the dehumidification heater are in normal operation.

Monthly inspection The monthly inspection needs to switch the generator set and the mains, and the generator set start-up and load test need to be in-depth inspection. Quarterly inspection During the quarterly inspection, the generator set needs to be at more than 70% load for 1 hour to burn out the mixture of diesel and engine oil in the cylinder. Annual inspection is an important part of the maintenance cycle of standby diesel generator sets, which not only requires quarterly and monthly inspections, but also needs to be maintained for more items.

The service life and operating power of diesel generator sets are not only in seasonal maintenance, but also very important for the daily maintenance of diesel generator sets. Starting from the details, we can make better use of diesel generator sets.

Daily maintenance: 1. Check whether the bolts of the stopper are loose and tighten them in time;

2. Check the oil level in the oil pan, and add oil when it is insufficient;

3. Check the oil volume of the balance bulk fuel tank;

4. Check the water surface of the water tank;

5. Check the joints of oil and water pipelines;

6. Check the intake and exhaust pipes and cylinders.

sealing of gaskets; Remove oil stains and dust from the surface and keep the computer room tidy;

Applicable to the maintenance scheme of standby generator set: (such as residential quarters, buildings, hospitals, government agencies, scenic spots, factories and other places with few power outages, only used for fire fighting, power outage maintenance, etc

Routine maintenance: On the basis of daily maintenance, maintenance can be done every six months or a year.

1. Conduct a comprehensive inspection of the water, electricity, oil and gas of the generator set to confirm whether the unit is normal;

2. No-load test machine for 5-10 minutes, so that the unit can be fully lubricated; Judge the use of the unit by listening, seeing, smelling and other methods;
