After shutting down your
diesel generator set, do you also immediately unplug it and leave? This habit could shorten your equipment life by 30% and even create a potential for serious failure! Below, we'll share a professional-level "final inspection" process. In just three steps, you can easily extend your unit's life by over three years and reduce maintenance costs by 50%!
Step 1: Cooling-down Check (Critical 5 Minutes)
After shutting down, never disconnect the power immediately! Key inspections include:
Return the oil pressure gauge to zero: If it doesn't, there may be an oil pump malfunction or a clogged line.
Return the coolant temperature to below 60°C: If this doesn't meet the standard, keep the fan running to prevent high-temperature damage to the cylinder block.
Let the turbocharger idle for 3-5 minutes: This prevents bearing seizure caused by sudden cooling and heating, which is the root cause of 80% of turbine failures!
Step 2: Fuel System "Deep Care" (Golden 3 Steps)
Drain the fuel filter: Check the water cup. If more than one-third of the water is present, replace the filter element. Otherwise, water will enter the high-pressure fuel pump and cause severe wear.
Inspect the fuel line connections: Touch each connection and tighten immediately if you notice any oil leakage to prevent fuel leaks and fires.
Winter Anti-Condensation Measures: If the unit is idle for more than 48 hours, drain the fuel system to prevent diesel from condensing and clogging the injectors.
Step 3: Electrical Component "Moisture-Proofing Package" (Core to Extending Life)
Battery Maintenance: Wipe the terminals with a dry cotton cloth and spray with a special antioxidant to prevent poor contact and starting failure.
Control Cabinet Inspection: Use a mobile phone flashlight to illuminate the cooling vents to ensure they are free of dust and prevent overheating and damage to the circuit boards.
Extended Shutdown Treatment: If the unit is idle for more than one month, it is recommended to remove the negative terminal of the battery to prevent battery depletion.
