Piston rings are placed within the piston grooves along the outer diameter of the compression piston. The primary purpose of the piston ring is the create a dynamic, pressure-activated, seal between the piston and the cylinder to allow the compression operation to take place. CDI presents various piston ring designs various piston ring designs and materials, ensuring optimal sealing and ring longevity.
The role of the wear ring is to provide a low-friction surface to carry the weight of the piston and prevent piston contact with the cylinder wall and reducing wear to the cylinder bore. CDI offers a variety of wear ring designs and materials, including polytetrafluoroethylene (PTFE) and bronze, which can be easily replaced for cost-effectiveness. These options help to ensure maximum wear ring longevity and efficient compressor operation.
Pressure packing rings serve as dynamic, pressure-activated seals. The fundamental sealing ring comprises an assembly of two or more segment-cut rings that overlap at the joints, creating a seal. Garter springs maintain the segments' cohesion and contact with the piston rod during assembly and compressor downtime. CDI presents various pressure packing styles and materials to ensure optimal sealing and ring longevity.
CDI produces a wide selection of non-metallic valve plates and poppets for use in reciprocating compressors. CDI valve components are injection molded and machined to customer specifications to ensure excellent surface finish and flatness. These plates endure impact and fatigue loads when coming into contact with the valve seat, and harsh gas, liquids, and debris that can reduce the overall life of the valve. CDI manufacture valve plates, poppets, and buttons from a variety of non-metallic materials including PEEK, Nylon, and MT as well as more specialty polymers such as carbon filled PEEK blends.
The primary purpose of the oil wiper is to prevent lubricating oil from the compressor frame from migrating along the piston rod and coming into contact with other critical sealing components within the compressor or mixing with the compressed gas. CDI offers various oil wiper designs in both metallic and non metallic materials to ensure optimal oil removal and wiper longevity.
PACKING CASE DESIGNPacking case design and manufacturing are crucial for reliable and efficient reciprocating compressor operation. Packing cases house a series of packing rings and seal high-pressure gas from exiting the cylinder along the path of the piston rod. CDI offers pressure, intermediate, and wiper assemblies tailored for all reciprocating compressor applications, utilizing a wide material range, reliable ring design, and top-notch engineering. Design considerations include gas type, operating pressure, temperature, compressor size, and stroke.
