Causes of The Silent Diesel Generator Sets Wear and Tear

Mar. 02, 2022

When the silent diesel generator set operation, there will be a problem of wear and tear of power generation. But the usersy do not know what causes this phenomenon, so they do not know how to check and maintain the quiet diesel generator set. Below, Starlight Power Generation Equipment summarizes the following reasons for everyone.

1. The ambient temperature around the time of use.

In relation to the surrounding air temperature, the temperature of the diesel engine will also increase as the air temperature increases, so that the viscosity of the lubricating oil will decrease, which will increase the wear of the parts. When the temperature drops, the viscosity of the lubricating oil increases, so that the silent diesel generator set will have certain difficulties when starting. Similarly, if the cooling water cannot be maintained at a normal temperature when the machine is working, it will also increase the wear and corrosion of parts. In addition, when the silent diesel generator set is started at low temperature, the wear and tear caused by the machine is more serious than that at high temperature.

2. The ambient temperature of the silent generator set operation.

And in the process of use, due to the constraints of the structure of the cooling system, the operating load and speed of the machine will be changed, so the temperature change of the machine itself will still have a great impact on the diesel engine, and it has been proved by practice that cooling The temperature of the water is controlled at 75~85℃, and the temperature of the lubricating oil is 75~95℃, which is most beneficial to the production of the machine.

3. The friction of the parts of the diesel engine will increase with the increase of the speed and load of the machine.

When the load is added, the friction between the parts will increase with the unit pressure increase on the surface. When the rotation speed is increased, the number of friction between the components will double within a unit time, and under the same power. However, too low speed can not guarantee excellent fluid lubrication conditions, and also increases wear and tear. Therefore, for a certain generator set, there is an optimal working speed plan.

4. The silent diesel generating set is often unstable in acceleration, deceleration, parking and starting.

Due to repeated changes in speed and load during operation, the silent diesel generator set has poor smooth conditions or unstable thermal conditions, and wear will increase. Especially when starting, the crankshaft speed is low, the oil pump is not supplied in time, the refueling temperature is low, the viscosity of the oil is high, the friction surface is difficult to establish a smooth liquid, and the wear is very serious.

Starlight Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
