Product Characteristics
Product Principles
The piston ring serves as the insulation layer between the piston and cylinder liner, and has the function of conducting heat. When an internal combustion engine is working, the piston absorbs the high-temperature gas in the combustion chamber and transfers heat to the piston ring. The piston ring then disperses the heat into the cylinder liner and cooling system through heat conduction.
During the operation of an internal combustion engine, the relative motion between the piston and cylinder liner will generate friction. In order to reduce friction loss, the piston ring forms a certain friction pair on the piston. The piston ring is usually in a strip shape, with both its internal and external surfaces mating with the piston and cylinder liner, and tightly fitting through a certain radial force. The material selection, surface treatment, and lubrication method of piston rings all affect the magnitude of friction
Product Technology
Forming processing often uses cold or hot extrusion processes to obtain the desired shape and size of the piston ring; Heat treatment can improve the hardness and wear resistance of piston rings; Precision machining improves the surface quality and accuracy of piston rings through grinding, polishing, and ultrasonic cleaning.

The manufacturing of piston rings requires multiple processes, including cutting, forming, heat treatment, and finishing. Among them, cutting is carried out through equipment such as CNC lathes and grinders to achieve precise control of piston ring geometric parameters
The product principles of piston rings include sealing principle, lubrication principle, guiding principle, heat dissipation principle, and the function of preventing impurities from entering. These principles together ensure the efficient operation, reliability, and durability of the engine and compressor. By optimizing the design and manufacturing process of piston rings, the performance and lifespan of products can be improved.
The piston ring also has the function of guiding the piston to move on the cylinder wall, ensuring the stability and accuracy of the piston. Through close contact with the cylinder wall, the piston ring limits the axial and radial displacement of the piston, preventing it from deviating from its normal motion trajectory.
The piston rings also perform lubrication functions. During operation, a small lubricating oil film is formed between the piston ring and the cylinder wall to reduce friction and wear. This helps to reduce energy consumption, extend piston ring life, and improve the efficiency of the engine or compressor
The piston ring is used to seal the gap between the piston and the cylinder block to prevent leakage of lubricating oil and combustion chamber gas. High quality piston rings can provide excellent sealing performance, ensuring the normal operation of the engine or compressor, and minimizing energy loss and environmental pollution
The piston ring is generally composed of several rings, closely connected on both sides. Common structures include oil rings, oil control rings, and upper and lower spiral grooves. The piston rings with different structures undertake different functions, such as sealing the cylinder, conducting heat, lubricating, etc.
