Description :

The rings used in reciprocating compressors are divided into two categories: sealing rings (piston rings) and rider rings. Piston rings have the function of sealing and preventing the passage of gas from one side of the piston to the other, and the rider rings are responsible for preventing the piston from contacting the cylinder body. The Important point in the design of the rings is temperature changes during compressor operation that cause expansion and contraction in the cylinder and piston and neglecting it causes serious damage to the compressor. This requires consideration of various parameters such as mechanical properties, chemical resistance of the material in a variety of environments, thermal behavior, and so on. Nika Compressor Rings are designed considering the compressor operating conditions including temperature, pressure, gas type, lubrication status, piston linear speed, liner material, etc. And are manufactured using polymers and engineering plastics from the most prestigious European brands.
