These Factors Will Determine The Service Life Of The Diesel Generator Set

May. 06, 2022

The cost of diesel generator sets is not low. In order to avoid premature damage to the unit and lead to early scrapping, users should pay attention to abide by the operating procedures when using them, and do not perform wrong operations. Otherwise, the failure rate of the unit will be greatly increased, resulting in high maintenance costs and increased operating costs. In order to improve the cost performance of the unit and reduce the operating cost, it is necessary for the user to understand which factors will determine the service life of the diesel generator set.


Diesel generators can operate at high loads, up to 80% to 90% of their capacity. Running a diesel generator in this way ensures that it gets enough combustion pressure to hold the piston rings firmly in place and, therefore, ensures the longevity of the diesel generator. However, it should not be higher than the load of the unit itself. Excessive load of the diesel generator will cause the machine to work excessively and affect the service life of the generator.


On the other hand, too lightly loaded diesel generators can cause several problems. Diesel generator sets or generator sets, whether standby diesel generator sets or primary rated diesel generator sets, are usually designed to operate between 50% and 85% of their capacity. Continuously rated gensets, on the other hand, are set to run between 70% and 100% of their load. Wet stacks can occur when any of these generator sets are operating at or below 30% of their capacity. Wet buildup is a black oily liquid that can leak from the exhaust fitting, it leaks because the engine has not reached its minimum temperature or pressure. When a leak occurs, it may indicate that the machine is under load. Doing this for extended periods of time can cause deposits to build up, which can lead to failures such as loss of power, poor performance, accelerated wear on the engine, etc.

The problem of accurate generator selection and the influence of incorrect load size will be detrimental to the life of diesel generators. The extent to which the life of the generator is shortened depends on the degree of overloading or underloading. The calculation of the most suitable size for your company involves taking into account generator frequency and voltage dips and their recovery time, other factors also affect power calculations.


Some of the following factors will also affect the service life of diesel generators, these factors include but are not limited to the following:


The quality of the generator usually depends on the manufacturer: the main brands include Yuchai, Shangchai, Cummins, Perkins, Volvo, Weichai, etc. In addition, the installation method and fuel problems will also affect the service life of diesel generators, such as plastic condensation or insufficient oxygen content. Availability of parts, especially for old or outdated generator environmental conditions such as extreme weather (from cold to hot), altitude, humidity, salt water and air, large amounts of sand and/or dust, etc. Almost any of these things, or a combination thereof, can lead to a shortened lifespan of a diesel generator.
