The role of the guide ring piston ring
May 09, 2022
1. The sealing function of the guide ring (the piston ring): the piston ring can maintain the seal between the piston and the cylinder wall, and control the air leakage to a minimum, which is borne by the air ring. It can prevent the seizure between the cylinder and the piston or the cylinder and the ring due to air leakage; it can also prevent the failure caused by the deterioration of the lubricating oil.
2. The heat conduction effect of the wear ring(piston ring): the piston ring can disperse the high heat transfer generated by combustion to the cylinder wall, which can cool the piston.
3. The oil control function of the guide ring(the piston ring): the piston ring can scrape off the lubricating oil attached to the cylinder wall and maintain normal oil consumption, which is borne by the oil ring.
4. Guide ring(piston ring) support: The piston ring moves up and down in the cylinder, and its sliding surface is fully borne by the ring, preventing the piston from directly contacting the cylinder and playing a supporting role.
The piston ring of the guide ring is divided into two types: the gas ring and the oil ring. The function of the gas ring is to ensure the seal between the piston and the cylinder, which is used to seal the compressed air in the combustion chamber; the oil ring is used to scrape the excess oil on the cylinder, which can prevent the Oil spills into the cylinder and burns.
