Title
(KO) 소형의 가변 기하학적 구조의 디퓨저 메커니즘
Abstract
(KO)
원심 압축기용 디퓨저 시스템이 제공된다. 디퓨저 시스템은 노즐 베이스 판(206)을 포함하고, 노즐 베이스 판은 디퓨저 간극(212), 지지 블록(216, 246), 및 지지 블록에 대해서 회전 가능한 구동 링(220)을 형성한다. 구동 링은, 구동 링의 외부 원주에 근접하여 배치된 캠 트랙(224, 242) 및 베어링 조립체(226, 234)를 포함한다. 디퓨저 시스템은 지지 블록 및 노즐 베이스 판을 통해서 연장되는 구동 핀(214)을 더 포함한다. 각각의 구동 핀의 제1 단부는 구동 링 상에 캠 트랙 내로 장착되는 캠 종동부(218)를 포함한다. 각각의 구동 핀의 제2 단부는 디퓨저 링(208)에 커플링된다. 구동 링의 회전은 캠 트랙 내의 캠 종동부의 이동에 의해서 구동 핀의 축방향 이동을 유발한다. 이는 디퓨저 간극을 통한 유체 유동을 제어하기 위한 디퓨저 링의 이동을 초래한다.
