How can the generator set be used to reduce component wear

In fact, the use process of diesel generator set is also the wear process of its parts. How to use diesel generator set reasonably and correctly is the primary condition to reduce wear and is also a method to extend the service life of diesel generator set.Diesel generator manufacturer Hua Quan power for you to explain the mystery.

One: diesel generator set fuel and lubricating oil quality to adapt

If the diesel contains sulfur or other impurities, it will produce acids or other corrosive substances during combustion, which will accelerate the wear of the cylinder.The heavy fractions in the diesel oil content are too much, forming carbon deposit after combustion, which causes abrasive wear of piston ring and cylinder.The viscosity of diesel oil affects the mixture formation and the reliability of oil supply equipment.For lubricating oil, the biggest influence is viscosity and oxidation resistance, should be based on the working conditions of diesel generator set reasonable choice of use, must not be misused.

The experimental results show that the friction of diesel generator sets increases with the increase of speed and load.As the load increases, the unit pressure on the friction surface increases, resulting in poor thermal conditions.When the speed increases, the number of times of friction per unit time increases by half, but under the same power, the speed increase is greater than the wear when the load increases.However, due to the low speed can not ensure good liquid lubrication conditions, also increase the wear, so, for a certain diesel generator set, there is a most suitable operating speed range.In addition, diesel generator sets often accelerate, decelerate, stop and start and other unstable work, due to the frequent change of speed and load, diesel generator sets poor lubrication conditions, thermal instability, wear will increase.Especially in starting, crankshaft speed is low, oil pump supply is not timely, refueling temperature is low, oil viscosity is large, friction surface is difficult to establish liquid lubrication, wear is very serious.

Two: the use of environmental temperature of the diesel generator set wear

When the temperature is high, the engine is easy to overheat, low oil viscosity, the wear of parts will increase.When the temperature is low, the viscosity of lubricating oil increases, which makes it difficult for diesel generators to start and operate, and the cooling water cannot keep the normal temperature during operation, which increases the wear and corrosion of parts.The wear of diesel generator set is more serious when starting at low temperature.

The operating temperature of diesel generator set is one of the important factors affecting wear and tear.In the process of operation, due to the limitation of cooling system structure, the change of work load and speed, the change of environmental temperature and other factors, the diesel generator set operating temperature has a wide range of variation.Practice shows that the temperature of cooling water is controlled at 75 ~ 85℃ and the temperature of lubricating oil is 75 ~ 95℃.

To sum up, in order to rationally use diesel generator sets and reduce wear and tear of components, diesel generator manufacturer Yangzhou Shengfeng instructs you to start from the following aspects:

1. Reasonable selection of operating conditions of diesel generator sets.

2. Improve the running-in quality of diesel generator.

3. Choose fuel and lubricating oil suitable for engine work.

4. Improve the technical level of operation and carry out timely maintenance.
