Do the three types of wear - abrasive wear, fusion wear and corrosion wear - coexist?

2016-08-15


Diesel engine in the break-in test run stage, due to the cylinder liner and piston ring surface microscopic roughness, so the wear is very strong. By grinding and up to the general case of simultaneous existence, and mutual influence. For example, melt and corrosion wear off the metal particles to accelerate abrasive wear, constitute the acidic components of corrosion wear reduce the performance of the lubricant, which in turn promotes melt wear, intensify abrasive wear. However, under certain conditions of use and working conditions, there is always a tendency for one type of wear to dominate.

Factors to consider when choosing a diesel engine

the use of diesel engines. For frequent starting and often moving machinery, such as tractors, agricultural vehicles, mobile power stations, etc., can choose light high-speed diesel engine; for fixed power devices, such as agricultural irrigation and drainage, agricultural by-products processing machinery supporting power, you can choose a lower speed and the potential of a larger diesel engine. At the same time, for agricultural power, most of the time long-term continuous operation, so good economy is very important.

What are the characteristics of the wear process of cylinder liners?

To the normal technical condition, because with the parts fit well, lubrication conditions are improved, in a longer working time, wear is slow and uniform. When due to wear and cylinder gap more than a certain value, due to the gas and oil leakage and moving parts of the knock and other factors, wear and increase.

Basic requirements for diesel engines

Basic requirements for diesel engines

This question concerns how to evaluate the diesel engine. With the development of socialist construction cause, China's diesel engine models continue to increase, the performance indicators gradually improve and enhance. At present, the domestic civilian diesel engine has more than one hundred kinds, there is a comprehensive use of high degree of general models, but also for special purposes of special models. In this case, how to correctly evaluate, reasonable choice of diesel engine is a very important issue.
