How to reduce the wear and tear of diesel generator parts

While the Diesel Generator is running the load, it is also the process in which the diesel Generator's own parts wear each other. Reducing wear between unit parts is actually a way to extend the life of the unit. So how do our users pay close attention to the extent to which diesel generator parts wear? The specific content is analyzed as follows:
First, the use of ambient temperature on the wear of diesel generators
When the temperature is high, the engine tends to overheat, the viscosity of the lubricating oil is low, and the wear of the parts increases. When the temperature is low, the viscosity of the lubricating oil becomes large, and the upper diesel generator is difficult to set up. The cooling water cannot maintain normal temperature during operation, which increases the wear and corrosion of the parts. Diesel generators wear more severely at low temperatures.
The operating temperature of a diesel generator is one of the important factors affecting wear. During the use process, due to the limitation of the structure of the cooling system, the change of the working load and the rotational speed, the change of the ambient temperature and the like, the operating temperature of the diesel Generator Set varies greatly. Practice has shown that the cooling water temperature is controlled at 75-85 ° C, and the lubricating oil temperature is 75-95 ° C.
Second, the quality of fuel and lubricants of diesel generators should be adapted
If diesel contains sulfur or other impurities, it will produce acid or other types of corrosive substances during combustion to accelerate the wear of the cylinder; too much heavy fraction in the diesel content, forming carbon deposits after combustion, making the piston ring Abrasive wear occurs with the cylinder; the viscosity of the diesel has an effect on the formation of the mixture and the reliability of the oil supply equipment. For lubricating oil, the viscosity and oxidation resistance are affected. It should be reasonably selected according to the working conditions of the diesel generator, and must not be used indiscriminately.
Tests have shown that the friction of diesel generators increases with increasing speed and load. As the load increases, the unit pressure on the friction surface increases and the thermal condition is poor. When the rotational speed increases, the number of frictions per unit time is increased by half, and at the same power, the rotational speed increases more than the load increases. However, too low a speed can not guarantee good liquid lubrication conditions, and also increases wear, so for a certain diesel generator, there is a * suitable working speed range. In addition, diesel generators often have unstable operation such as acceleration, deceleration, parking and starting. Due to frequent changes in speed and load, diesel generators have poor lubrication conditions, unstable thermal conditions, and increased wear. Especially at the start, the crankshaft speed is low, the oil pump is not supplied in time, the oil temperature is low, the oil viscosity is large, and the friction surface is difficult to establish liquid lubrication, and the wear is very serious.
In summary, it is necessary to use diesel generators reasonably to reduce the wear and tear of parts, and guide everyone to start from the following aspects:
1. Reasonably select the operating conditions of the diesel generator.
2. Improve the running-in quality of diesel generators.
3. Select fuels and lubricants suitable for the working needs of diesel engines.
4. Improve the technical level of operation and timely maintenance.
