Aluminum alloy Oxidized Compressor pump cylinder barrel

Aluminum alloy Oxidized Compressor pump cylinder barrel An oil-free air compressor is a type of compressor designed to compress air without the use of lubricating oil. This helps prevent oil contamination of the final compressed air, which is crucial for applications that require pure air such as medical equipment, food processing, etc. In oil-free air compressors, special materials and techniques are usually used to reduce friction between the piston or rotor and the cylinder wall. The common method is to use self-lubricating materials to make piston rings or cups (also known as sealing rings). These materials can provide good sealing performance without external lubrication and have a long service life. Cylinder liner A cylinder liner refers to a lining installed on the inner wall of a cylinder, which is usually used to protect the cylinder wall from wear or to improve the sealing performance of the cylinder. In oil-free air compressors, cylinder liners are usually made of wear-resis…
