Diesel generator recycling, reusing, and maintenance specifications are worth noting. Technical maintenance of diesel generators involves regular systematic, detailed inspections, adjustments, and cleaning of all components to ensure optimal working conditions necessary for the normal operation of diesel generators. This helps prevent premature wear and accidents, maximizing the operational efficiency and economic benefits of diesel generators. Therefore, a practical and feasible maintenance plan must be established during the use of diesel generators, and all maintenance tasks should be carried out meticulously.
Section 1: Diesel Generator Recycling and Daily Maintenance
1. Check the crankcase oil level, and add oil if it's low.
2. Inspect for any leakage at the oil pump, water pump, filters, and all connections; if leakage is found, it should be eliminated.
3. Ensure the fuel tank is adequately filled with fuel; top up if necessary.
4. Inspect the stability of bolt connections on the diesel generator base and its accessories.
5. Check if all instrument junctions are loose and if the pointers have returned to zero.
6. Check if the operating mechanism is flexible and reliable.
7. Check the tension of each triangular drive belt to ensure it is appropriate; adjust if necessary.
8. Keep the diesel generator's control room clean.
Section II: Diesel Generator Recovery & Reuse - Level 1 Technical Maintenance
Regularly sweep and wipe the machine room, removing oil stains, water marks, and dust from the generator components to maintain cleanliness.
2. Check and adjust the intake and exhaust valve clearances.
3. Apply lubricating oil to all oil nozzles and lubrication points.
4. Inspect and eliminate leaks (oil, water, gas, electricity).
5. Check the tension of the drive belt on the charging generator fan (normally, apply 3 to 5 kilograms of pressure in the middle of the V-belt, and the belt should depress 10 to 20 millimeters).
6. Replace the three filters (engine oil, fuel, air)
7. Inspect if the injection pump drive bolt is loose, and re-adjust the injection timing.
8. Inspect the fuel tank and oil/water separator for water presence, identify the cause, and promptly rectify.
9. Replace lubricating oil according to the specifications for different models and oil quality conditions.
10. Inspect the drive belt tension and protective cover, as well as the reliability of the electrical protection circuit (low oil pressure, high water temperature).
11. Regularly inspect the intake and exhaust manifolds of the turbocharger, check for any leaks, clean, and blow out the intake ducts or air filter (blow the air filter every 200 hours).
12. Measure the insulation resistance, which should be greater than 0.5 ohms.
13. Inspect bearing lubrication and humidity conditions. If the temperature is too high, analyze the cause, remove it promptly, and add lubricating oil. This should be done cumulatively every 100 hours or one month.
Section 3: Diesel Generator Recycling and Reuse - Level 2 Technical Maintenance
In addition to following the procedures of the first-level maintenance, the following items must also be included in the second-level maintenance.
1. Clean pistons, piston pins, cylinder liners, piston rings, and connecting rod bearings, and inspect their wear conditions.
2. Inspect for any looseness in the inner and outer rings of the main rolling bearing.
3. Scale and silt in the cooling water system channels.
4. Carbon deposits in the combustion chamber and intake/exhaust passages of the cylinder head.
5. Inspect the wear on mating surfaces of the valves, valve guide tubes, valve seats, push rods, and rockers, and perform grinding adjustments as needed.
6. Clean, inspect the oil pump, oil cooler, and their pipelines.
7. Inspect the oil pump outlet valve and plunger assembly for proper fit, adjust the flyweight pin and drive斜盘, check the thrust plate for wear, and replace parts if necessary.
8. Inspect, adjust, and verify the atomizer,喷油器, its injection pressure, and atomization condition.
9. Clean carbon deposits from the turbocharger's turbine rotor, inspect bearing and impeller wear, and replace if necessary.
10. Inspect the bolts on the generator and diesel engine connector for looseness or stripped threads; if issues are found, they should be repaired or replaced.
11. Inspect the insulation wrapping for signs of aging and abrasions due to overheating, and repair any damage promptly.
