Types of Rider Rings
One-Piece Rider Rings
One-piece rider rings are designed for simplicity and efficiency. They are commonly used in single-acting compressors where the design allows for straightforward installation and maintenance. These rings provide reliable sealing capabilities, preventing the piston from making contact with the cylinder wall.
Multi-Piece Rider Rings
Multi-piece rider rings, which can come with or without expansion springs, are ideal for high-load applications. They offer enhanced flexibility and can be customized based on specific compressor designs. This adaptability makes them suitable for a wide range of operational environments.
Pressure Relieved Rider Rings
Pressure relieved rider rings feature specialized designs, including rectangular or angular sections, which help to alleviate pressure build-up during operation. This design is beneficial for both single and double-acting compressors, as it ensures better sealing and reduced wear over time.
Twin Rings
Twin rings consist of two interlocking pieces and are designed for high-performance applications where optimal sealing is crucial. They minimize leakage and enhance the efficiency of the compressor. Their complex design allows them to perform exceptionally well under rigorous operational conditions.
Polymer Rider Rings
Polymer rider rings are engineered for extreme conditions, such as high temperatures and pressures. Made from high-performance materials, these rings are lightweight and resistant to corrosion, making them ideal for specialized applications that require durability and reliability.
Applications of Rider Rings
Industrial Compressors
Rider rings are predominantly used in industrial compressors where maintaining pressure and preventing gas leakage is critical. Companies like Cook Compression and STASSKOL offer various designs tailored to meet the demands of different industrial applications.
