Product Characteristics
Note
Before installing the piston ring, be sure to apply an appropriate amount of lubricating oil to the piston ring groove. This helps to reduce friction and wear, and provides a good sealing effect. At the same time, avoid excessive lubricating oil entering the piston ring to avoid affecting normal movement and sealing performance.
Before installing a new piston ring, thoroughly clean the piston groove and piston surface. Remove dirt, oil stains, and other debris to ensure proper insertion and movement of the piston rings. At the same time, ensure the use of clean tools and gloves to avoid contamination of piston rings and related components.
In the production process, we strictly adhere to the international quality management system, from raw material procurement to finished product delivery, every step undergoes strict quality control and testing. Our products have passed multiple certifications and tests to ensure their excellent quality and reliability.
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.
