Why does the noise of diesel generators increase after running for a long time?

1. Carbon deposits are generated in diesel generators

Because the old oil of the unit is used for a long time, it becomes thinner and thinner, so there are more and more carbon deposits. Thin oil is easy to leak oil, resulting in more and more carbon deposits and a lot of power loss. When the new oil is replaced, the diesel generator cannot adapt to the viscosity of the oil, which may increase the speed, resulting in a loud noise of the generator.

2. Loose mechanical parts of the unit

When the mechanical parts of the diesel generator are loose during long-term operation, the noise will also increase. Sometimes it is very likely to cause a malfunction, and the noise of the generator will gradually increase. This should be checked and replaced to avoid other malfunctions.

3. Human psychological effect

Human hearing has errors in different environments. Of course, if you want to really distinguish the size of the noise, you have to use a decibel meter for testing.

It is recommended that users can configure a silent box for the unit if they want to reduce the noise when the diesel generator is in use. The biggest advantage of the silent generator set is that it has low noise, reduces noise pollution to the environment, and reduces noise to the personal injury of the unit operator. In addition to the functions of the series diesel generator sets, the silent diesel generator set also has the following features: low noise, compact overall structure, small space occupation; the box is a detachable structure, the box is made of steel plates, the surface is coated with high-performance anti-rust paint, and it has noise reduction and rainproof functions; the box adopts a multi-layer barrier impedance mismatch silencer structure and a built-in large impedance silencer. The box structure is reasonably designed. This is also the most effective way for users to deal with the noise when the diesel generator is running.
