Product Characteristics
Product Technology
Conduct comprehensive and strict inspection and quality control of piston rings at all stages of the production process. By using various measuring tools and equipment, check the size, shape, surface quality, and performance indicators of the piston ring to ensure that it meets the specification requirements.
The piston ring also has the function of preventing impurities from entering between the piston and the cylinder block. The structure and position of the piston ring can prevent impurities such as external particulate matter and dust from entering the piston system, ensuring internal cleanliness and normal operation.
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.
