The piston ring is a metal ring which is used to insert into the groove of the piston. There are two kinds of piston rings: compression ring and oil ring. The compression ring can be used to seal the combustible gas mixture in the combustion chamber; the oil ring can be used to scrape off the excess oil on the cylinder.
The piston ring is a kind of metal elastic ring with large outward expansion deformation, which is assembled into the section and its corresponding ring groove. The reciprocating and rotating piston ring, depending on the pressure difference of gas or liquid, forms a seal between the circular surface of the ring and the cylinder as well as one side of the ring and the ring groove.
The flat steel wire of piston ring produced by our company has four functions: sealing, adjusting oil, conducting heat and guiding. There are two kinds of commonly used automobile engines, diesel engine and gasoline engine. Because of their different fuel performance, the piston rings used are not the same. The early piston rings are formed by casting. However, with the progress of technology, the steel high-power piston rings are born. With the continuous improvement of engine function and environmental requirements, various advanced surface treatment applications, such as thermal spraying and electroplating, are applied Chromium plating, gas nitriding, physical deposition, surface coating, zinc manganese phosphating treatment, etc., greatly improve the function of piston ring.
