To ensure that the automatic diesel generator can start reliably and provide stable power during a mains power outage, a systematic maintenance system must be established. Maintenance of the automatic diesel generator mainly revolves around daily inspections, regular maintenance, preventive testing, and long-term storage management.
I. Daily and Weekly Inspections of Automatic Diesel Generators
Daily inspections are the foundation for ensuring that automatic diesel generators are always in standby condition. Every day, the fuel, engine oil, and coolant levels of the automatic diesel generator should be checked to ensure they are sufficient, and it should be checked for any 'three leaks' (oil leak, water leak, air leak).
At the same time, the automatic diesel generator and the engine room environment should be kept clean, ensuring that the inlet and outlet vents are not blocked. Weekly, the battery's charge status and electrolyte level (if applicable) should be checked to ensure it has sufficient power.
II. Regular Technical Maintenance of Automatic Diesel Generators (Based on Operating Hours)
It is important to perform graded maintenance according to the cumulative operating hours of the automatic diesel generator:
1. Level 1 Maintenance (every 50-80 hours of operation): Clean or replace the air filter of the automatic diesel generator, replace the engine oil, oil filter, diesel filter, and coolant. At the same time, check and adjust the tension of the fan belt and alternator belt.
2. Level 2 Maintenance (every 250-300 hours of operation): Based on Level 1 maintenance, the automatic diesel generator requires deeper inspections and cleaning, including checking the valve clearance, cleaning carbon deposits from the turbocharger rotor, and checking for wear on bearings and impellers.
3. Level 3 Maintenance (every 500-1000 hours of operation): This is more comprehensive maintenance, including checking and adjusting the fuel injection timing of the automatic diesel generator, cleaning the fuel tank and oil pan, checking the atomization of fuel injectors, and inspecting the fasteners connecting the generator and diesel engine.
III. Monthly/Quarterly Preventive Testing and In-Depth Inspection of Automatic Diesel Generators
1. For standby automatic diesel generators that are not frequently used, it is recommended to conduct a load test at least once a month. Before the test, manually start the automatic diesel generator to check if it starts smoothly, and record whether parameters such as voltage, current, frequency, oil pressure, and water temperature are normal during operation. The test run is recommended to last 8-12 minutes, with 3-5 minutes of idling before shutdown to allow the lubricating oil and cooling water to carry away heat.
2. In addition, the electrical system should be inspected quarterly or semiannually, including cleaning and tightening all terminal connections and measuring the insulation resistance of the Automatic Diesel Generator windings.
IV. Annual Maintenance and Long-Term Storage of Automatic Diesel Generators
A comprehensive maintenance should be carried out once a year. In addition to covering all the above items, the coolant in the radiator should be replaced, and the insulation performance of the automatic diesel generator should be tested.
If the automatic diesel generator needs to be stored for a long period, the fuel tank and the coolant system must be drained, or a stabilizer should be added, the inside of the engine should be treated for rust prevention, and the battery connection should be disconnected. The generator should then be stored in a dry and ventilated place.
V. Special Maintenance of Key Components and Systems of Automatic Diesel Generators
1. Cooling System: It is necessary to regularly check whether the radiator of the automatic diesel generator is blocked by debris and clean the scale in the cooling system waterway. It is recommended to clean the outside of the radiator every 200 hours of operation.
2. Crankshaft and Lubrication System: Before starting, ensure that the oil pressure of the automatic diesel generator is normal. Overloading and 'racing' are strictly prohibited to prevent damage to the crankshaft caused by poor lubrication or excessive additional load.
3. Fuel System: It is recommended to replace or clean the main fuel in the fuel tank every 12 months to avoid using contaminated diesel. At the same time, regularly drain any water that may accumulate at the bottom of the fuel tank.
4. Automatic Control System: Regularly check the ATS (Automatic Transfer Switch) control cabinet of the automatic diesel generator. Simulate a mains power failure to test whether the unit can start, supply power, transfer, and shut down automatically according to the preset program.
VI. Q&A on Knowledge Related to Automatic Diesel Generators
1. What are the key protection functions of an automatic diesel generator?
It has multiple protections, including low oil pressure, high water temperature, overvoltage, undervoltage, overload, overspeed, etc. In case of serious faults, it will automatically alarm and shut down to protect the automatic diesel generator.
2. Where are automatic diesel generators primarily used?
They are mainly used in places with high requirements for power continuity, such as data centers, hospitals, communication base stations, high-rise buildings, financial centers, industrial and mining enterprises, and large event venues, serving as emergency or backup power sources.
3. What should be considered when selecting an automatic diesel generator?
The key is to determine the unit capacity based on the total load power, and confirm whether specific functions such as full automatic transfer (ATS), remote monitoring, silent operation, or mobility are required, choosing the automation level that fits the application scenario.
