Cylinder Liners Wear Reasons

Wear Reasons for Cylinder Liners

It is well known that heavy-duty machinery cylinder liners will experience wear and tear after prolonged use. The mud pump valve box improves the lubrication conditions of the heavy-duty machinery special cylinder liner. The air ring mainly ensures the sealing between the piston and the heavy-duty machinery special cylinder liner.

Depending on the working conditions and the pressure it bears, the material selection and structural design of each air ring are different. If the piston ring is installed incorrectly, installed upside down, or missed, it can cause poor sealing or no oil scraping effect, deteriorating the lubrication conditions on the inner surface of the heavy-duty machinery special cylinder liner and causing oil shortage and cylinder pulling.

Due to the differences in product structure and performance, the reasons for wear and tear also vary. Heavy machinery specific cylinder liners belong to a type of cylinder liner, and in practical applications, wear and tear may occur. So what are the reasons for the wear of heavy-duty machinery special cylinder liners?

1, The upper part of the cylinder is severely worn, which is related to inhaling a large amount of dust or severe carbon buildup. The air filter should be maintained or replaced, the carbon buildup should be removed, and whether it is caused by oil leakage should be checked.

2, Severe wear on the piston ring at the top dead center indicates engine overheating and poor heat dissipation. The cooling system and ignition system (including spark plug selection) should be checked, and the connecting rod big end bearing should also be checked for looseness.

3, The lower part of the cylinder liner for heavy machinery is severely worn, and the engine oil contains a large amount of metal abrasive particles or dust. It should be replaced with clean engine oil.
