Product Characteristics
Product Description
The sealing effect between the piston ring and cylinder wall directly affects the performance of internal combustion engines. An excellent piston ring design should achieve good sealing effect, while also considering the balance of friction and wear. If the piston ring is loose or severely worn, it can cause problems such as decreased cylinder pressure, incomplete combustion, and oil pollution.
Product Process
The manufacturing of piston rings began with mold design and manufacturing. A mold is a necessary tool for manufacturing piston rings, used to press metal materials into a specific shape of the ring. The design of the mold needs to consider the size, shape, and structure of the piston ring, as well as the wear resistance and durability of the mold.
Different types of piston ring products provide higher performance and reliability through high-quality materials, special coatings, and low friction design, meeting the needs of different engines for piston rings
The main purpose of piston rings is to ensure the sealing performance between the piston and cylinder wall, prevent gas leakage, reduce friction and wear, improve combustion efficiency and power output, and reduce the generation of pollutants
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.
