A Diesel generator is processing the electric generator to generate electrical energy. This is the specific case of engine-generator. A diesel compression-ignition engine often is designed to run fuel oil also some types are adapted to run with liquid fuels or natural gas.
Generator Users require less maintenance due to their durability (it means measures the length of product life), reliability (it means product will not fail within specific period of time) and the sturdiness characteristic (It means durability of product) and also they are considered cheaper to operate due to the low fuels costs as compared to the other types of fuels such as gasoline and propane.
Also considered withstand heavy load for long hours and start off the power supply on the full load within minutes and must be regularly maintained to ensure they provide quality power throughout their service life.
The best generator maintenance practice is following the maintenance schedule provided by the generator manufacturer to ensure maximum service time for the generator and proper operation when it is called upon to provide power.
The engine is the core component of the generator. If you want to run your generator well without any mechanical issues or electrical issues must maintain the generators carefully.
Once you start to running of the diesel generator, the exhaust system, fuel system, DC electrical system and engine require close monitoring for any leaks that can cause hazardous occurrences. The very essential one is to maintain the internal combustion engine.
Step 1: Lubrication Service
The Engine oil must be checked while power off the generator at regular intervals using a dipstick.
Allow the oil in the upper portion of the engine to drain back into the crankcase and follow the engine manufacturer recommendations for API oil classification and oil viscosity.
Keep watching the oil level as near as possible to the full mark on the dipstick by adding the same quality and brand of oil. The oil and filter must also be changed at particular time intervals. Check regularly with the engine manufacturer for procedures for draining the oil and replacing the oil filter and their disposal is to be done appropriately to avoid environmental damage or liability.
Step 2: Cooling System
Check the coolant oil level during shutdown periods at the specified interval.
Must be noted these points “remove the radiator cap after allowing the engine to cool, and, if necessary, add coolant until the level is about 3/4 in” And More critical role is balancing diesel engines require a balanced coolant mixture of water, antifreeze, and coolant additives.
Examine the exterior of the radiator for obstructions, and remove all dirt, grimy or foreign material with a soft brush or cloth with caution to avoid damaging the fins.
If available means, use the low-pressure compressed air or a stream of water in the opposite direction of normal airflow to clean the radiator.
Please don’t remove the pressure cap from a hot engine. Wait until the coolant temperature is below 120°F (50°C) before removing the pressure cap. Because heated coolant spray or steam can cause injury.
Step 3: Fuel System
Diesel is subject to contamination and corrosion within a period of time is one year, and therefore regular generator set exercise is highly recommended to use up stored fuel before it degrades.
The fuel filters should be drained at the designated intervals due to the water vapour that accumulates and condenses in the fuel tank.
Better check regularly testing and fuel polishing may be required if the fuel is not used and replaced in three to six months.
Step 4: Testing Batteries
If the batteries charges reach the dead-end level are a common cause of standby power system failures.
The battery must be kept fully charged and well-maintained all-time 40% to 100% to avoid by regular testing and inspection to know the current status of the battery and avoid low battery level.
Do you want to increase batteries performance? Must be cleaned, and the specific gravity and electrolyte levels of the battery checked frequently.
- Testing batteries
- Cleaning batteries
- Checking specific gravity
- Checking electrolyte level
Step 5: Routine Engine Exercise
Regular exercising keeps the engine parts lubricated and thwart oxidation of electrical contacts, uses up the fuel before it deteriorates, and helps to provide reliable engine starting.
Engine exercise is recommended to be executed 15 days once or 25 days once for a minimum of 30 min
Step 6: Keep your Diesel Generator Clean
Maintain your engine all-time nice and clean because it will be taken care of Oil drips and other issues. Check day-by-day hoses and belts that are in good condition or not.
Frequent checks can keep better condition and other nuisances from nesting in your equipment. However, the generator users thought is a generator set that is rarely used might not need a lot of care. So, please avoiding these kind thoughts keep maintaining the generator based on manufacturer guidelines.
Step 7: Exhaust system inspection
In case any leaks along the exhaust line which usually occurs at the connection points, the welds and the gaskets. Find the place of leakages and repaired immediately by a technician.
Step 8: Operating Inspections
Following the manufacturer guidelines when designing inspections to be performed when the generator is operating.
Common Manufacturer Inspections guidelines for diesel generators below,
- Disconnect generator batteries.
- Drain fuel system and change fuel filters.
- Drain coolant and change coolant filters.
- Replace air filters.
- Ensure all intake and exhaust ports are covered.
- Disconnect all generator supply connections.
