Product Characteristics
Basis Information
The dimensional accuracy of piston rings is crucial for their installation and sealing performance. High quality piston rings require precise size control to ensure good fit with the piston and cylinder block to achieve the best sealing effect.
Piston rings are usually treated with special surface treatments to provide better friction and wear resistance. Common surface treatment methods include hard coating, phosphating treatment, etc.
The dimensional accuracy of piston rings is crucial for their installation and sealing performance. High quality piston rings require precise size control to ensure good fit with the piston and cylinder block to achieve the best sealing effect.
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.
