The maintenance and upkeep of open frame type generator sets are key to ensuring their reliable operation and extending their service life. The following are detailed maintenance steps and precautions, covering daily inspections, regular maintenance, and other aspects.
1、 Daily check of open frame type generator set (daily/before each startup)
Appearance and environmental inspection
Cleanliness: Clean the surface dust and oil stains of the open frame type generator set, and check for any debris accumulation around it. Fasteners: Check if bolts and nuts are loose. Leakage situation: Observe whether there are any signs of leakage in the engine oil, fuel, and coolant.
Liquid level and pressure inspection
Engine oil: Pull out the dipstick and check if the oil level is within the range of the scale. Coolant: Check the level of the expansion tank and replenish soft water or antifreeze if insufficient (avoid mixing different brands). Fuel: Confirm that the fuel tank has sufficient fuel and avoid mixing water or impurities.
Electrical system inspection
Battery voltage: Use a multimeter to measure the battery voltage. Connecting terminals: Check if the battery terminals are corroded and tighten loose terminals. Starting motor: Test whether the starting motor is working properly.
2、 Regular maintenance of open frame type generator set (based on running hours or time intervals)
Maintenance after 50 hours of initial operation
Replace the engine oil and oil filter (key maintenance is required during the running in period of a new engine). Check and tighten all connecting components.
Maintenance every 250 hours or 6 months
Open frame type generator set air filter: Clean or replace the paper filter element (adjust according to the ambient dust concentration).
Fuel filter: Replace the filter element to avoid fuel system blockage.
Coolant: Check the concentration (e.g. ethylene glycol antifreeze needs to be replaced regularly, usually once every 2 years).
Maintenance every 500 hours or 1 year
Valve clearance: Adjust the engine valve clearance (requires professional tools and techniques).
Injector: Check the injection pressure and atomization condition (diesel unit).
Belt and Chain: Check the tension of the drive belt and replace it if necessary.
Maintenance before long-term storage
Cleaning and rust prevention: Clean the unit and spray rust inhibitor on exposed metal parts.
Battery maintenance: Disconnect the negative terminal of the battery and charge it once a month to prevent sulfurization.
Fuel treatment: Drain the fuel tank or add fuel stabilizer (to prevent deterioration).
3、 Open frame type generator set security operation specification
Preparation for starting
Confirm that the load switch is in the disconnected state. Check that there are no flammable materials around and that there is good ventilation.
Monitoring during operation
Do not touch high-temperature components such as exhaust pipes and turbochargers. Monitor the sound of the unit's operation and immediately shut down if any abnormalities are detected.
Operation after shutdown
Run without load for 3-5 minutes before stopping to avoid overheating of the turbocharger. Close the fuel valve and battery switch, and lock the control cabinet door.
The maintenance of the open frame type generator set ensures reliable start-up and continuous power supply in emergency situations through daily inspections, regular maintenance, quick response to faults, and strict safety operations. Suggest developing a detailed maintenance schedule and optimizing maintenance strategies based on actual operational data.More information on open frame type generator sets:https://hq-power.net/
