Product Characteristics
Product Introduction
Type of piston ring:
Compression ring: The compression ring is located in the groove at the top of the piston, used to seal the combustion chamber and prevent compressed gas from leaking onto the cylinder wall. It can withstand high temperatures and pressures, and has good elasticity and wear resistance.
Oil control ring: The oil control ring is used to control the oil film between the piston and cylinder to reduce the amount of oil film entering the combustion chamber, while ensuring an appropriate amount of lubricating oil to lubricate the piston and cylinder wall. It is usually composed of two or three separate rings and has excellent sealing and lubrication performance.
Explosion ring: The explosion ring is located at the bottom of the piston ring group to enhance the sealing performance and stability of the piston ring. It can prevent high-temperature and high-pressure gas from leaking to the bottom of the piston, and improve combustion efficiency and emission control.
The production of piston rings involves multiple processes, including material preparation, cutting and forming, heat treatment, surface treatment, precision machining, inspection, and quality control. Through strict process control and quality management, piston ring products with excellent performance and precise dimensions can be produced
The piston ring reduces the frictional resistance when in contact with the cylinder wall by using low friction materials and surface treatment technology. This not only improves the engine's output power and fuel economy, but also reduces the generation of noise and vibration, enhancing driving comfort
Note
Proper lubrication and cleaning: 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.
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 trajector
Clean the piston groove:
Use tools such as a scraper to clean carbon deposits and dirt from the piston groove.
Gently grind the surface of the piston groove with sandpaper or a grinding tool to ensure a smooth surface.
Install new piston rings:
Before installation, ensure that the new piston ring matches the piston and carefully check its condition.
Use piston ring pliers to carefully place the piston ring into the piston groove, ensuring that the opening of the ring is correctly aligned.
Lubrication and assembly:
Apply a small layer of lubricating oil between the piston ring and piston groove to reduce friction and promote sealing effect.
Reinstall the piston onto the connecting rod and connect other engine components in the correct order.
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.
