In recent years, the application of cylinder liners in the engine field has become more and more widespread, and the phenomenon of replacing engine cylinder liners has become more and more frequent. What are the factors that cause this phenomenon? Here is a brief introduction to the main factors that affect the service life of the engine cylinder liner.
1. The water filter is replaced irregularly and the softened water is not used as required, which causes serious cavitation of the cylinder liner.
2. The function of the water filter is to prevent cavitation of the cylinder liner and scale formation in the water system. When the circulating cooling water flows in the waterway, many bubbles will be generated. When these bubbles pass through the outer wall of the cylinder liner, the bubbles will expand rapidly and become larger and even rupture due to the high temperature of the cylinder liner. When the bubble bursts, blasting force will be generated, which will peel off the surface metal on the outer wall of the cylinder liner and expose the inner metal. The water often contains hydrogen ions, which will form acidic substances, which will peel off the outer wall of the cylinder liner. Such repeated action will cause pitted caves on the outer wall of the cylinder liner. As the use time increases, the caverns will become larger and larger, which will affect the use strength of the cylinder liner.
3. Since the circulating water also contains calcium, magnesium and barium ions, these ions are the main substances that form scale. Scale adheres to the outer wall of the cylinder liner and around the combustion chamber and affects heat conduction, making it difficult for the heat of the combustion chamber to be transferred to the cooling water.
The above content mainly introduces the main factors that affect the service life of the engine cylinder liner, and I hope it can be helpful to everyone.
