Abstract

본 발명은 캔드펌프의 회전자축 지지장치에 관한 것으로 특히 회전자축 지지구조를 단순화 함으로써 원가를 절감할 수 있고 회전자축 지지부외로의 누수를 방지할 수 있도록 한 것으로 펌프가 작동하여 유체가 유출될 때 유체가 스테이터 캔 내부에서 스테이터 캔 외부로 누출되는 것을 방지하기 위하여 스테이터 캔의 내부면이 회전자축을 지지하는 슬리브베어링의 외주면에 밀착되도록 상기 스테어터캔에 형성된 축소관부와, 상기 축소관부가 슬리브베어링의 외주면에 압입되어 밀착되게 구성한 것이다.The present invention relates to a rotor shaft support device of a can pump, in particular, to reduce the cost by simplifying the rotor shaft support structure and to prevent leakage to the rotor shaft support portion, when the pump is operated by the fluid flow out of the fluid The reduction tube portion formed in the stator can so that the inner surface of the stator can adheres to the outer circumferential surface of the sleeve bearing for supporting the rotor shaft to prevent leakage of the inside of the stator can to the outside of the stator can. It is configured to be in close contact with the outer peripheral surface.
