The air compressor cylinder liner is an important component in the air compressor, which has the following main functions:

1.Guiding function: The cylinder liner provides a stable motion track for the piston, ensuring that the piston reciprocates in a straight line in the cylinder, reducing friction and wear.

2.Forming working space: The cylinder liner and piston together form the working space for compressed air.

3.Extend the service life of the cylinder body: The cylinder liner can absorb the heat generated by the piston movement and control the working temperature of the cylinder through the cooling of the cylinder liner, thereby extending the service life of the cylinder body.

4.Wear resistance: Cylinder liners are usually made of wear-resistant materials, such as high-quality gray cast iron or alloy steel, to withstand the friction of high-speed piston rings and pistons.

5.Heat dissipation function: The cylinder liner helps to dissipate the heat generated in the cylinder, keep the cylinder temperature stable and avoid overheating.

The material of the cylinder liner is generally wear-resistant and strong, such as wear-resistant alloy cast iron containing phosphorus or boron. Sometimes the inner surface is also chrome-plated, nitrided or phosphated to improve wear resistance. The inner surface hardness of the cylinder liner is usually required to be greater than HB200, and the hardness of the piston ring must be properly matched.

In addition, the maintenance of the cylinder liner is also very important. It is necessary to regularly check its wear and tear, ensure the cooling and lubrication of the cylinder liner, and promptly detect and replace the damaged cylinder liner to ensure the normal operation and service life of the air compressor.
