Product Characteristics
Product Process
Strict testing and quality control of piston rings are carried out during the production process. Common testing methods include size measurement, surface finish inspection, hardness testing, and wear resistance testing. Ensure that the piston rings meet design requirements and standards.
Note
Ensure that the selected piston rings match the specifications and requirements of the engine or compressor. This includes dimensions, materials, and models. Choosing the wrong piston ring may result in poor sealing performance and performance loss.
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.
