Factors Affecting Diesel Generator Power Reduction

In general, the power of diesel generator sets will decrease after a period of use. This is because the long-term use and wear of the equipment will lead to a decrease in product power. So, what are the specific causes of the power reduction of diesel generator sets, and how to prevent it?

First of all, it is a normal phenomenon that the power of diesel generator sets decreases after being used for a period of time. Because when the power part of the diesel generator set, namely the engine, is working, many parts will slide or rotate at a high speed under a certain load, such as the"piston"and"cylinder liner","crankshaft"and"bearing", etc. Although the surfaces of these parts are lubricated to varying degrees, with the increase of working time, the surfaces in contact with each other will inevitably wear due to long-term friction, gradually destroying the original size and geometric shape. This normal wear is often called"natural wear", which is unavoidable in actual situations.

Secondly, the power of the diesel generator set is also related to the amount of air and the amount of diesel that can be burned. The temperature and humidity of the air will also affect the power output of the diesel generator set. For example, high air temperature and high humidity will also reduce the power output of the diesel generator set.

In addition, some parts of the diesel generator set will affect the power change of the diesel generator set after being used for a long time. The reasons are as follows:

The machine filter element is blocked, the air filter is too dirty, and the intake air is insufficient. At this time, the air filter must be cleaned or replaced.

The fuel filter device is too dirty, and the fuel injection volume is insufficient. Treatment method: must be replaced or cleaned.

The ignition time is incorrect. At this time, it is necessary to adjust the ignition time to ensure the normal use of the generator set.

Insufficient oil intake of the diesel engine;

Diesel engine fuel injection pump failure;

Generator set filter element blockage;

Diesel engine valve not closing tightly;

Poor atomization of diesel engine injector;

Wear of generator set piston ring and cylinder liner

Dingbo Power Tips:Regarding the operation and use of diesel generators, no matter how good the quality of the machinery or how wear-resistant the materials are, if they are operated and used improperly, their service life will not be long.

After understanding the factors that affect the power reduction of diesel generators, how can we prevent and reduce it and extend the service life of the unit?
