Maintenance is One Key to Diesel Generator Set Reliability
Due to the durability of diesel engines, most maintenance is preventative in nature and necessary to ensure maximum performance and reliability. Generator service is set at every 250 hours, or every 6 months depending on the application (Standby, Prime and Continuous). Preventive diesel engine maintenance consists of the following operations:
- General inspection
- Lubrication service
- Cooling system service
- Fuel system service
- Servicing and testing starting batteries
- Regular engine exercise
It is important to establish and adhere to a schedule of maintenance and service, based on the specific power application and the severity of the environment. For example, if the generator set will be used frequently or subjected to extreme operating conditions, the recommended service intervals should be reduced accordingly. Some of the factors that can affect the maintenance schedule include:
- Using the diesel generator set for continuous duty (prime power)
- Extreme ambient temperatures
- Exposure to weather
- Exposure to salt water
- Exposure to dust, sand or other airborne contaminates
If the generator set will be subjected to some or all of these extreme operating conditions, it is best to consult with the engine manufacturer to develop an appropriate maintenance schedule. The best way to keep track of maintenance intervals is to use the running time meter on the generator set to keep an accurate log of all service performed. This log will also be important for warranty support.
Benefits of planned maintenance
Improves system reliability. Planned maintenance will see a cost reduction. Equipment can be shut down to coincide with production downtime. Prior to the shutdown, any required parts, supplies and personnel can be gathered to minimize the time taken for a repair. These measures decrease the total cost of the maintenance.
The dangers of unplanned maintenance
Unplanned, reactive maintenance has many overhead costs that can be avoided during the planning process.
The cost of unplanned maintenance includes lost production, higher costs for parts and shipping, as well as time lost responding to emergencies and diagnosing faults while equipment is not working. Unplanned maintenance typically costs three to nine times more than planned maintenance.
