Product Characteristics
Product Principles
The secondary ring is located below the compression ring, which is generally thicker and less strong than the compression ring. Its function is to prevent lubricating oil from entering the combustion chamber while also serving as a seal. Compared with compression rings, the cross-sectional shape and working principle of secondary rings are similar. The oil ring is located at the bottom of the piston ring groove, and its main function is to scrape away lubricating oil and return it to the oil pan to reduce friction between the piston and the cylinder.
Product Process
The raw materials for the plug ring need to be prepared, including ring parts and accessories. These parts need to be cleaned and inspected to ensure their quality and dimensions meet standards. Cut the prepared materials into appropriately shaped workpieces according to the design dimensions. Common piston ring shapes include circular rings and comb shaped rings. Blanking is usually done using a cutting machine or laser cutting equipment.
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.
