Piston rings for reciprocating compressor
Main functions of compression rings :
Piston rings, mounted on the pistons of lubricated or non-lube (oil free) compressors, are designed to ensure that the gas is compressed and to provide a seal between the piston and the cylinder.
The piston ring is an essential part of a reciprocating compressor, as it enables the requested or required performance in terms of flow rates and pressures to be achieved..
High-performance piston rings :
To optimize these characteristics the leakage rate must be kept to a minimum, which is why CASTANET :
- manufactures its piston rings in a wide range of extremely wear-resistant materials.
- also offers a wide range of designs for improving the sealing function according to the pressure, molecular weight of the gases (specially in the case of low density gases) and the materials used.
Different types of cut and configurations are studied to minimize residual leakage and the effects of wear on sealing performance.
All of these technical solutions enable the service life of the compressors to be extended and thus reduce operating costs (improved volumetric efficiency, increased service between scheduled overhauls).
