DY Piston Ring

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.
