A typical preventive maintenance scheme in Generating sets, so as to ensure correct operation and optimal performance, includes the following actions:
- Technical inspection and checking of the generating set and its installation room in order to identify if the conditions of operation are according to standards. More specifically:
- Liquid Leakages (coolant liquid, oil, fuel)
- Gas leakages (exhaust pipes and silencer)
- Excessive and abnormal vibrations
- Abnormal noises during operations
- Loose connections
- Ventilation of the generating set’s room
- Battery’s electrolyte level
- Radiator coolant level
- Lubrication oil level
- Cleaning and replacement (if needed) of the following spare parts according to manufacturer’s standards:
- Air filter (cleaning or replacement)
- Oil filter (replacement with every oil change)
- Fuel filter (replacement according to manufacturer’s manual)
- Oil change (according to manufacturer’s manual)
- Drive belts (check and replacement if needed)
- Checking, adjusting, cleaning and replacement (if needed) of the following spare parts according to manufacturer’s standards:
- Injectors (check and replace if needed)
- Adjust valve clearance
- Thermostat (check)
- Feed pump (check and clean)
- Main fuel pump (check and adjust)
- Fuel pump governor
- Radiator (clean)
- Generator and AVR (Check and adjust if necessary)
- Battery (check – refill electrolyte or replace if necessary)
- Control panel and connections (check)
- De-assembling of spare parts (if necessary) and cleaning:
- Radiator (if necessary)
- General Generating set cleaning
- After the end of the maintenance, the Generating set is tested, both without and with load, in order to examine if its operation meets manufacturer’s standards. If needed, the following adjustments are made:
- Voltage, current and engine’s frequency according to gauges.
- Engine temperature
- Oil pressure
- Battery charging
- Check all engine’s protections
- Check indication lamps
