Daily Maintenance Contents of a Good Diesel Generator

Time：2026-05-07 15:41:25 Edit：HuaQuan Traffic Index：320

Proper daily maintenance of a good diesel generator is the guarantee that it will function when needed. Many good diesel generators do not fail from use, but from being left unused or poorly maintained. The following introduces the daily maintenance contents of a good diesel generator for users' reference.

I. Pre-start Checks for a Good Diesel Generator
1. Check the three liquids: Inspect the levels of engine oil, coolant, and fuel in the Good Diesel Generator to ensure they are within the normal range. Do not start if oil or water is insufficient. At the same time, check for any leaks at the system pipe connections.
2. Appearance and cleanliness: Clean oil stains and dust from the surface of the Good Diesel Generator. Check the surrounding area for rags, tools, and other debris to keep the generator clean and orderly.
3. Intake system: Check whether the air filter is blocked and if the indicator signals an alarm. In environments with a lot of wind and sand, blockage is a common cause of power loss and black smoke.

4. Belts and fan: Visually inspect the Good Diesel Generator's fan belt for lateral cracks or wear. Press the center of the belt with your finger to check if the tension is within the specified range.
5. Electrical system and battery: Check if Good Diesel Generator the battery terminals are secure and free of oxidation. Ensure the battery voltage is normal and the charge is sufficient, which is crucial for smooth starting.
6. Fuel system: Loosen the drain screw at the bottom of the fuel filter to release any accumulated dirty fuel and water.

II. Monitoring of a Good Diesel Generator in Operation
1. Instrument Parameters: Closely observe the oil pressure, water temperature, voltage, current, and frequency of a good diesel generator. If any abnormal fluctuations occur, shut down immediately and inspect.
2. Sound and Exhaust Smoke: Listen for any abnormal sounds such as metal knocking from a good diesel generator. Observe the color of the exhaust smoke; light gray is normal. Black smoke may indicate poor combustion, blue smoke may indicate oil burning, and white smoke may indicate water ingress or low temperature.
3. Leak Inspection: Routinely check the oil, fuel, and coolant lines of a good diesel generator for any leaks.

III. Post-Shutdown Procedures for a Good Diesel Generator
1. Idle Cooling: Before shutting down a good diesel generator, first remove the load and let the engine run at idle for 3-5 minutes. This allows the lubricating oil and coolant to carry away the heat from high-temperature components such as the combustion chamber and bearings, preventing carbon buildup in the turbocharger.
2. Recording and Cleaning: Record the operational data of the diesel generator for this run, and perform cleaning and inspection again.

IV. Key Precautions
1. Long-term storage requires maintenance: If a good diesel generator is not used for a long time, make sure to run it idle for 10-15 minutes every month and charge the battery. Long-term idling can easily cause oil seal aging, oil circuit blockage, and battery failure.
2. Always use genuine consumables: Poor-quality engine oil, antifreeze, and filters are the main causes of major engine failures such as cylinder scoring and bearing seizure. The replacement cycle for good diesel generator engine oil and filters is usually 250 hours or six months, and for air filters 500-600 hours, and they must be replaced when the time is up, even if unused.
3. Safety precautions: Never open the radiator cap when the coolant is hot to avoid burns.

V. Q&A on Knowledge of Good Diesel Generators
1. What is the difference between the rated power and standby power of a good diesel generator?
Rated power can run continuously for a long time; standby power can only run for a total of no more than 1 hour within 12 hours and cannot be overloaded.
2. Why must the generator room of a good diesel generator be kept clean?
If the diesel engine inhales dirty air, its power declines; if the generator inhales sand particles, it may burn the stator and rotor insulation.
3. How should a good diesel generator that is not used for a long time be maintained?
Drain the fuel, change to new engine oil, remove the battery and charge it regularly, and run it unloaded for 10 to 15 minutes each month.
