Product Description
28XP Dry Gas Seals John Crane Mechanical Seal for Ebara Turbine Compressors
28XP
28XP Dry Gas Seals (equivalent to John Crane Type 28XP DGS), Ebara Turbine Compressors
High-Temperature, High-Pressure Dry Gas Seals for Ebara Turbine Compressors.
Design Parameters
- Tandem dry gas seal
- Medium Temperature: -40 to 150 °C
- Static Pressure: 8.618 MPa
- Dynamic Pressure: 5.869 MPa
- Rotary Speed: 14643 r/min
Actual Operating Conditions
- Operating Pressure: 4.647 MPa
- Operating Temperature: 140 °C
- Rotary Speed: 13312 r/min
- Medium: 97.56% CH₄, 1.5007% N₂, H₂S, etc.
Design Features
- For high-pressure, high-temperature turbine compressors, only explosion-proof "spring energized seals" can be selected as auxiliary sealing rings.
- Structural component design must undergo rigorous static analysis and optimization.
- The stability of the dynamic pressure effect generated by the dynamic pressure groove and the stiffness-to-leakage ratio must undergo rigorous dynamic analysis and verification tests.
- The isolation sealing structure requires special design and testing to ensure accurate control of nitrogen consumption.
