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,...

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 ...
Non-contacting Gas Seal for Turbo CompressorsType 28 compressor dry-running gas seals have been the industry standard since early 1970 for gas-handling turbomachinery. Utilizing John Crane’s patented spiral groove pattern, these seals are non-contacting in operation. During dynamic operation, the ...
Type 28AT: The original gas seal, with a design pedigree stretching back over 30 years and evolving gradually, installed and proven in thousands of compressors all around the world and remaining the preferred seal choice for many customers. Type 28 compressor dry-running gas seals have been the...
