Products Description
Screw compressors air end shaft seal is a seal used in screw air compressors. Its main function is to seal the gap between the air end shaft and the casing of the air compressor to prevent leakage of compressed air and lubricating oil.
Screw Compressors Air End Shaft Seal-Mechanical Sealing Solutions
Advantages
- Prevents contamination intrusion: In a normally operating oil-injected screw compressor, the shaft seal prevents the intrusion of contaminants and keeps the compressed air and oil where they should be when shut down.
- Reliability: Using PTFE shaft seals can ensure that the compressor reduces leakage failures, thereby improving the reliability of the compressor.
- Suitable for high speed and high temperature: Some screw compressors air end shaft seal designs can withstand speeds up to 4,000 to 14,000 RPM and temperatures up to 350°F (177°C), while also handling vacuum pressures up to 25 PSI (1.7 BAR).
- Low friction coefficient: Provides good motion performance, and reduces energy loss and wear.
- Wide range of applications: Can be used in many types of screw compressors to adapt to different industrial applications.
👉The material is mainly PTFE, which has excellent chemical resistance and high-temperature resistance, and is suitable for various industrial application machinery, including but not limited to compressors.
