The First Condition to Reduce Wear and Tear of Tongchai Diesel Generator Set

Jul. 16, 2021

The process of using Tongchai diesel generator set is actually a process of wear and tear of the diesel generator set parts. How to use Tongchai diesel generator set reasonably and correctly is the first condition to reduce wear and tear, and it is to extend the service life of Tongchai diesel generator set. One way, the diesel generator set manufacturer Jiangsu Starlight Power Generation Equipment Co., Ltd. will explain the mystery for you.


1. The wear and tear of Tongchai diesel generator set by the temperature of the operating environment.

When the temperature is high, the engine is easy to overheat, the lubricating oil viscosity is low, and the wear of the parts increases. When the temperature is low, the viscosity of the lubricating oil becomes larger, and the Tongchai diesel generator set is difficult to operate, and the cooling water cannot maintain the normal temperature during operation, which increases the wear and corrosion of the parts. The wear and tear of Tongchai diesel generator sets is more serious when starting at low temperature.

The working temperature of Tongchai diesel generator set is one of the important factors affecting wear. In the course of use, due to the limitation of the cooling system structure, the change of working load and speed, the change of ambient temperature and other factors, the working temperature of Tongchai diesel generator set has a wide range of changes. Practice shows that the cooling water temperature is controlled at 75~85℃, and the lubricating oil temperature is most advantageous when the temperature is between 75~95℃.

In summary, to use Tongchai diesel generator sets reasonably and reduce the wear of parts, the diesel generator set manufacturer Jiangsu Starlight Power Generation Equipment Co., Ltd. instructs you to start from the following aspects:

1) Reasonably choose the operating conditions of Tongchai diesel generator sets.

2) Improve the running-in quality of Tongchai diesel generator sets.

3) Choose the fuel and lubricating oil suitable for the working needs of the engine.

4) Improve the level of operation technology and carry out maintenance in time.


2. The quality of the fuel and lubricating oil of Tongchai diesel generator set should be compatible.

If the diesel contains sulfur or other impurities, it will produce acids or other types of corrosive substances during combustion, which will accelerate the wear of the cylinder; there are too many heavy distillates in the diesel, which will form carbon deposits after combustion and make the piston ring Abrasive wear occurs with the cylinder; the viscosity of diesel fuel has an impact on the formation of the mixture and the reliability of the fuel supply equipment. For lubricating oil, viscosity and oxidation resistance are the most influential. It should be reasonably selected and used according to the working conditions of Tongchai diesel generator sets, and should not be used indiscriminately.


The test shows that the friction of Tongchai diesel generator set increases with the increase of speed and load. Because when the load increases, the unit pressure on the friction surface increases, resulting in poor thermal conditions. When the speed increases, the number of frictions per unit time increases by half, and under the same power, the increase in speed is greater than the wear when the load increases. However, a too low speed cannot guarantee good liquid lubrication conditions and also increases wear. Therefore, for a certain Tongchai diesel generator set, there is a most suitable working speed range. In addition, when Tongchai diesel generator sets often accelerate, decelerate, stop and start and other unstable work, due to frequent changes in speed and load, Tongchai diesel generator sets have poor lubrication conditions, unstable thermal conditions, and increased wear. Especially when starting, the crankshaft speed is low, the oil pump is not supplied in time, the oil temperature is low, the oil viscosity is high, the friction surface is difficult to establish liquid lubrication, and the wear is very serious.
