Phosphating cylinder liner factory will introduce to you: the inner surface of the cylinder liner is directly affected by high-temperature and high-pressure gas, and is in direct contact with the piston ring, and the inner surface is subject to strong high-speed sliding friction. The surface is in contact with cooling water, and severe thermal stress is generated under a large temperature difference,
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. .
Phosphating cylinder liner manufacturers will introduce to you: In order to improve the wear resistance and corrosion resistance of the cylinder liner, the surface of the cylinder liner can be treated during the overhaul, and the method is as follows:
Phosphating cylinder liner manufacturers will introduce to you: In order to achieve the initial running-in without cylinder wear, the surface roughness of the cylinder liner should be reduced as much as possible when honing the cylinder liner. According to the experiment, the intersection angle θ=22-23° of the grinding texture is the best, it can obtain a larger pressure bearing surface, and at the same time has a good oil holding capacity. In order to avoid the repetition of wear marks, v reciprocating/v circle must not be an integer.
Phosphating cylinder liner manufacturers will introduce to you: When disassembling and inspecting the engine, it is often found that there are many obvious scratches on the surface of the piston skirt, and the contact surface between the piston ring and the cylinder wall also has similar stretch marks, accompanied by burnt colors. Sometimes the engine is far from running to the overhaul period, and the wear of the cylinder liner has reached the limit, which puts forward certain requirements on the surface quality of the cylinder liner.
Iveco Cylinder Liner is a cylindrical part, which is placed in the cylinder block hole of the machine body, and is pressed and fixed by the cylinder head. The piston reciprocates in its inner hole and is cooled by cooling water outside.
