DY Piston Ring

Product Description

The piston ring is a metal elastic ring with a large outward expansion deformation, which is assembled into the corresponding annular groove of the section. The reciprocating and rotating piston rings rely on the pressure difference of gas or liquid to form a seal between the outer circular surface of the ring, the cylinder, one side of the ring and the ring groove.

Scope of Application

DY Piston rings are widely used in various power machinery, such as gasoline engines, diesel engines, air compressors, hydraulic equipment, etc. Generally, the piston ring is installed in the ring groove of the piston, and it forms a chamber with the piston, cylinder liner, cylinder head and other components to do work.

The function of piston rings includes sealing, regulating oil (oil control), heat conduction (heat transfer), guidance (support) four roles. Sealing: refers to sealing gas, do not let the combustion chamber gas leakage to the crankcase, the gas leakage is controlled at a minimum, improve thermal efficiency. Gas leakage will not only make the power of the engine drop, but also make the oil deteriorate, which is the main task of the gas ring; Regulating oil (oil control): Scrape off the excess lubricating oil on the cylinder wall, and at the same time make a thin oil film on the cylinder wall to ensure the normal lubrication of the cylinder, piston and ring.
