Phosphating cylinder liner factory introduces the relevant knowledge of cylinder liners

Phosphating cylinder liner factory will introduce to you: judgment and analysis of cylinder liner wear

The cylinder liner is an important part of the diesel engine. It forms the combustion chamber with the piston and the cylinder head. The abnormal wear of the cylinder liner will cause poor lubrication, cause gas blow-by between the cylinder liner and the piston ring, directly affect the efficiency of the diesel engine, and determine the overhaul period of the diesel engine. . Therefore, it is particularly important to judge the abnormal wear of the cylinder liner. Waste products will cause unnecessary losses and directly affect the interests of the manufacturer; Under the conditions of strong friction, poor lubrication, empty running, improper cooling, abnormal combustion and the entry of fine particles, the inner surface of the cylinder liner will be worn.

Structural form of cylinder liner

Phosphating cylinder liner factory tells you: the cylinder liner is a centrifugally cast iron casting. Axial positioning is achieved by the cooperation between the upper shoulder of the cylinder liner and the supporting surface of the body (or spacer sleeve), and the upper sealing is completed through the grinding and matching of the supporting surface. The rubber sealing ring on the lower ring belt is sealed with the body to ensure the sealing of the lower water jacket and the radial positioning of the cylinder liner. The cylinder liner is a wet cylinder liner, which has the advantages of no sealing water jacket on the body, easy casting, good heat transfer, relatively uniform temperature distribution, and convenient inspection and maintenance. There is a protruding ring on the top surface of the cylinder liner to match the corresponding groove on the bottom plane of the cylinder head, and a sealing gasket is pressed in the middle to ensure the sealing of the combustion chamber. Press the cylinder liner against the body from the top.
