Product Characteristics
Product Principles
When the piston moves inward and upward in the cylinder, the compression ring is slightly opened by the action of the cylinder wall, forming a small gap where gas enters. As the piston continues to rise, the gas is compressed and detonated during the downward stroke. After combustion and exhaust, the compression ring begins to act as a seal, preventing gas reflux and pressure loss.
The compression ring is located at the top of the piston ring groove and is mainly responsible for sealing the high-pressure gas in the cylinder. Its design structure determines its working principle. Compression rings are usually made of cast iron or steel, with a special wear-resistant material coated on the surface.
Product Usage
The piston ring is located between the piston and the cylinder, serving as a seal for the cylinder.The piston ring effectively seals the cylinder, creating a stable pressure environment inside the cylinder. This helps to ensure that the engine operates normally and provides sufficient power output.

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.
