1. First-level technical maintenance of 800kw diesel generator: (50-80 hours) Add to the content of daily maintenance< /p>

1. Clean the air filter and replace it if necessary;

2. Replace the diesel filter, air filter, and water filter;

3. Check the tension of the drive belt;

4. Add lubricating oil to all oil nozzles and lubricating parts;

5. Replace the cooling water

II. 800kw Second-level technical maintenance of diesel generator: (250-300 hours) added to the content of daily maintenance and first-level maintenance

1. Clean the piston, piston pin, cylinder liner, piston ring, connecting rod bearing and Check its wear and tear;

2. Check whether the inner and outer rings of the rolling main bearing are loose;

3. Remove scale and sediment in the water channels of the cooling water system;

4. Clear the carbon deposits in the cylinder combustion chamber and intake and exhaust passages;

5. Check the valves, valve seats, push rods and rocker arms for wear and tear, and perform grinding adjustments;

p>

6. Clean the carbon deposits on the turbocharger rotor, check the wear of the bearings and impellers, and replace them if necessary;

7. Check whether the bolts of the coupling between the generator and the diesel engine are loose. Sliding teeth should be repaired if problems are found.

3. Three-level technical maintenance of 800kw diesel generator: (500-1000 hours) added to the contents of daily maintenance, first-level maintenance and second-level maintenance

1. Inspection and adjustment Lift the fuel injection angle;

2. Clean the fuel tank;

3. Clean the oil pan;

4. Check the atomization of the fuel injection nozzle
