Abstract
폐쇄형 원심 펌프의 동적 시일 구조는 전·후방 보호판과 유입 작동 유체의 압축을 위해 전·후방 보호판사이에 제공된 일련의 블레이드로 구성되는 임펠러를 갖추며, 전방 보호판의 라이너 링 상에 형성된 제1면과 펌프 케이싱의 마멸 링 상에 형성된 제2면 사이에 형성된 축방향 틈새를 포함하고, 상기 제1면과 상기 제2면은 펌프 구동 샤프트의 축방향에서 서로에 대해 대향한다. 축방향 틈새는 펌프의 작동 중에 임펠러의 회전으로부터 생기는 원심력에 의해 경계면 내의 작용 유체를 외향으로 이동시킴으로서 고압 측면으로부터 마멸 링과 라이너 링 사이의 경계면을 거쳐 저압 측면으로의 작용 유체의 후방 흐름을 막기 위해 배치된다.The dynamic seal structure of the closed centrifugal pump has an impeller constituted by a front and a rear shield plate and a series of blades provided between the front and rear shield plates for the compression of the inflow working fluid and has a first surface formed on the liner ring of the front shield plate And an axial gap formed between a second surface formed on the wear ring of the pump casing, wherein the first surface and the second surface are opposed to each other in the axial direction of the pump drive shaft. The axial clearance prevents the back flow of working fluid from the high pressure side to the low pressure side through the interface between the wear ring and the liner ring by moving the working fluid out of the interface by centrifugal force resulting from rotation of the impeller during operation of the pump .
