Product Characteristics
Product Principles
The piston ring is a key component used in internal combustion engines, which plays a sealing role between the piston and the cylinder. According to its product principle, piston rings can be divided into compression rings (upper ring, secondary ring) and oil control rings (oil ring).
Product Feature
Wear resistance: The piston ring needs to maintain good sealing performance with the cylinder wall, so it needs to have excellent wear resistance to prevent friction loss with the cylinder wall.
Low friction coefficient: In order to reduce friction loss and energy consumption, piston rings need to have a lower friction coefficient to improve engine efficiency.
Reliable sealing performance: The piston ring needs to have reliable sealing performance to avoid gas leakage in the combustion chamber, ensure combustion efficiency and emission requirements.
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.
