Abstract | PURPOSE: A centrifugal pumping device is provided to reduce the occurrence of warm current at right upper part of an outflow port by the geometrical shape of the pump and to offer effective low warm current delivery and output of sensitive fluid. CONSTITUTION: The device comprises:an outer side part; a structure for a passage to pass fluid into the hollow part; an inlet(19) formed from the outer side of the structure by centering a hollow inner part having wall in its inside and to pass the fluid; an outlet placed on radial form the axial center of the structure and formed from the outer side of the structure for the passage to pass the fluid from the hollow inner part of the structure; and a magnet piece where the fluid flow passing through the structure converts from the inlet to the outlet gradually, and to provide suspension function to an impeller piece(21) by being separated from the hollow inner part of the structure.
(ⅰ) 일체형 전자기 베어링에 의해 전체적으로 지지되고 일체형 모터에 의해 회전되는 일체형 임펠러 및 로터 (ⅱ) 유체 유동 및 구속을 위한 펌프하우징 및 아크(arc)모양의 통로 (ⅲ) 펌프하우징과 일체로 삽입된 브러쉬레쓰(brushless)구동모터 (ⅳ) 전원공급 및 (ⅴ) 효율적이고 내구성이 있으며 정비보수가 적은 펌프작동을 제공하도록 서로 모두 끼워맞춤 연결되는 전자기 베어링 전류 및 모터의 백 엠프로부터의 입력에 기초한 모터 속도 및 펌프성능을 위한 가체 감지 방법 및 생리학적 제어알고리듬을 이용하여 임펠러의 위치, 속도 또는 가속도의 전자적 감지를 포함하는 민감한 생리학적 유체를 펌핑하기 위해 원심유체펌프를 위한 장치 및 방법에 의해 된다. |
