Product Characteristics
Product Features
Due to the fact that piston rings not only need to withstand high temperatures and pressures, but also need to come into contact with fuel and lubricating oil, they need to have good corrosion resistance. Proper surface treatment and material selection can improve the corrosion resistance of piston rings and extend their service life.
Good high-temperature resistance: In high-temperature environments, the piston ring needs to maintain a stable size and shape, without excessive expansion or loss of elasticity. The appropriate piston ring material and design can maintain good performance in high-temperature environments, ensuring the normal operation of the engine
Product Advantages
The piston ring withstands the harsh working environment of high temperature, high pressure, and high-speed internal combustion engines, therefore it needs to have excellent wear resistance and durability. High quality piston ring materials and advanced surface treatment technology can enhance its wear resistance and service life, reducing maintenance and replacement frequency.
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.
