PURPOSE: To ensure a V-shaped seal clearance by providing a web between a support ring and a slide ring and selecting a distance from a shaft of the web to give a resultant force acting in the direction in which the seal clearance is expanded as a force pressing the slide ring on a ...
Within the gas lubricated shaft seals, dry gas seals (DGS) are the most common type of seals used in the Oil & Gas industry. The Dry Gas Seal outperforms other types of seals for demanding applications and are specified by standards like the API 692. Its main task is to prevent uncontro...
In this webinar on Dry Gas Seals and Seal Gas Filtration, Mark Slotnick shares the John Crane in-depth understanding of the newest API standard and its implication for all segments of the Oil & Gas industry. Taking a close look at: • Comparison to earlier API standards • ...
The Kaydon Dry Gas Seal (K-DGS) is installed in the most demanding and critical hydrocarbon processing applications.

DryGasSeal Overview 干气密封 恒钜工程技术有限公司 原理 螺旋槽干气密封运行原理。当旋转环高速旋转时,旋转环或静止环端面上的螺旋槽将外径处的高压气体向下泵入密封端面间,气体由外径向中心流动,而密封坝节制气体流向中心,于是气体被压缩引起压力升高,在槽根处形成高压区。端面气膜压力形成开启力,在密封稳定运转时,...

The seal can be regarded as two sets of single-end dry gas seals connected end to end; the primary seal bears all or most of the load, and the secondary seal can be used as a backup seal with high safety. The process gas leaking through the primary seal is introduced into the flare...
