Technical Features:
1.High-strength seal materials for optimal performance.
2.Balanced design with precisely calculated face pressure ratio to reduce face load and minimize heat generation.
3.Stationary multi-spring design provides excellent followability, reduces centrifugal effects on springs, and maintains stable spring and sealing performance.
4.Large-cross-section sealing rings maintain floatability while enhancing sealing performance.
5.The highly reliable drive design effectively prevents slippage even on high-hardness shafts.
Solution Selection:
A barrier/buffer fluid system is required to provide lubrication and cooling for seal operation, with barrier fluid pressure typically 0.14~0.41MPa higher than seal chamber pressure. Plan 53A, 53B or 54 systems can be selected for barrier fluid circulation.
