Product Technology

 

To ensure the dimensional accuracy of the piston ring, precision machining is required. Use CNC machine tools and other processing equipment to perform processes such as turning, grinding, and polishing on piston rings to achieve the geometric shape and surface quality required by the design.

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

 

 

Product Process

 

The piston rings also aid in the conduction and dissipation of heat. The piston ring can quickly transfer heat from the piston to the cylinder wall, thereby achieving heat dispersion and cooling. This helps to maintain the normal operating temperature inside the engine or compressor and protects the pistons and other components from overheating damage.

 

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

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.High Level Diesel Piston Rings For Hino RF8 CD520 138.0mm 2.5+2.5+4 8 No.Cyl 4

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.
