Description
본 발명은 자기 구동 펌프의 액체 유동에서 가스를 검출하기 위해 증기 검출기를 사용하는 것에 관한 것이다.The present invention relates to the use of a vapor detector to detect gas in the liquid flow of a magnetically driven pump.
자기 구동 펌프는 공지되어 있으며, 통상적으로 원심 펌프 임펠러를 구동시키는 자기 커플링(magnetic coupling)을 포함한다. 모터 드라이브(motor drive)는 자기 커플링의 외부 자기 로터에 연결된다. 자기 커플링의 내부 자기 로터는 펌프 임펠러에 연결된다. 밀봉 벽은 외부 자기 로터와 내부 자기 로터 사이에 위치되어 완전한 유체 밀봉을 제공함으로써, 외부 자기 로터가 "건조" 측부에 유지되게 한다. 액체는 벽의 내부의 "습윤" 측부 내에서 순환한다. 원심 펌프 임펠러는 입구로부터 출구로 액체를 이동시킨다.Magnetic drive pumps are known and typically include a magnetic coupling that drives a centrifugal pump impeller. The motor drive is connected to an external magnetic rotor of the magnetic coupling. The inner magnetic rotor of the magnetic coupling is connected to the pump impeller. The sealing wall is positioned between the outer magnetic rotor and the inner magnetic rotor to provide a complete fluid seal, thereby allowing the outer magnetic rotor to remain on the "dry" side. The liquid circulates within the "wet" side of the interior of the wall. Centrifugal pump impellers move the liquid from the inlet to the outlet.
종래 기술은 기포, 또는 펌프의 습윤 측부에 위치하는 액체 내의 다른 가스를 검출하기 위해 기포 검출기를 포함해 왔다.The prior art has included bubble detectors to detect bubbles or other gases in the liquid located on the wet side of the pump.
자기 구동 펌프는 원심 펌프를 구동시키는 자기 커플링을 포함한다. 모터는 자기 커플링의 외부 자기 로터를 구동시킨다. 외부 자기 로터는 밀봉 벽의 방사상 외향으로 위치된다. 내부 자기 로터는 밀봉 벽 내에서 방사상으로 위치된다. 외부 자기 로터의 회전은 내부 자기 로터가 회전하게 유도한다. 내부 자기 로터는 원심 펌프 임펠러가 액체를 이동시키도록 구동한다. 기포 검출기는 벽의 외측에 위치됨으로써 펌프의 건조 측부에 위치하게 된다. 기포 검출기는 펌프 액체 내부의 가스의 존재를 식별하기 위해 펌프의 습윤 측부로 신호를 보낸다.The magnetic drive pump includes a magnetic coupling for driving the centrifugal pump. The motor drives the external magnetic rotor of the magnetic coupling. The outer magnetic rotor is located radially outward of the sealing wall. The inner magnetic rotor is located radially within the sealing wall. Rotation of the outer magnetic rotor induces the inner magnetic rotor to rotate. The internal magnetic rotor drives the centrifugal pump impeller to move the liquid. The bubble detector is located on the dry side of the pump by being located outside the wall. The bubble detector signals the wet side of the pump to identify the presence of gas inside the pump liquid.
본 발명의 이러한 특성 및 다른 특성은, 하기에 간략하게 설명된 하기의 명세서 및 도면으로부터 잘 이해될 수 있다. These and other features of the present invention can be better understood from the following specification and drawings, briefly described below.
도 1은 본 발명의 펌프를 관통한 단면도이다.
도 2는 기포 검출기 프로브의 장착부의 상세도이다.1 is a cross-sectional view through the pump of the present invention.
2 is a detailed view of a mounting portion of the bubble detector probe.
유체 펌프용 습윤 측부(40)로부터 건조 측부(23)를 분리시키는 밀봉 벽(22)을 구비한 자기 구동 펌프가 도 1에 도시되었다. 분리식 모터는 베어링 하우징(24)을 통해 샤프트(28)를 구동시킨다. 샤프트(28)는 벽(22)의 외측에 위치된 외부 자기 로터(30)를 구동시킨다. 자속은 벽(22)을 통과하여 내부 자기 로터(32)를 구동시킨다. 원심 펌프 임펠러(34)는 내부 자기 로터(32)에 연결된다. 유체는 입구(35)로부터 임펠러(34)를 통과하여 출구(37)로 구동된다.A magnetic drive pump with a
기포 검출기 프로브(36)는 벽(22)의 외측에 위치되어 제어기(38)와 통신한다. 프로브는 초음파 신호를 송수신하는 초음파 프로브일 수 있다. 액체를 통한 신호 전달은 가스를 통한 신호 전달과는 상이하다. 그러므로, 프로브는 습윤 챔버 내부의 유체가 액체인지, 가스인지 또는 액체와 가스의 혼합물인지를 결정할 수 있다.The
자기 구동 펌프는 임펠러(34)에 의해 펌핑되는 일부 액체를 수용하는 "습윤" 측부(40)를 포함하며, 이로써 액체는 밀봉 벽(22) 내에서 부품 주위를 방사상으로 순환할 수 있다. 또한, "건조" 측부(23)는 벽의 방사상 외향으로 위치되어 액체를 수용하지 못한다. 프로브(36)는 건조 측부(23)에 위치된다.The magnetic drive pump includes a “wet”
알 수 있는 바와 같이, 프로브(36)는 임펠러(34)로부터 이격된 습윤 측부(40)의 일부와 대면한다. 이러한 위치 설정은, 하우징 벽(100)에 의해 임펠러로부터 분리된 챔버의 일부와 프로브(36)를 정렬시킨다.As can be seen, the
도 2로부터, 또한, 도 1을 참조하여 알 수 있는 바와 같이, 프로브(36)는 부싱 홀더(bushing holder; 100)에 대향하게 위치된다. 외부 하우징 벽(101)은 하우징 내에 프로브를 고정하여 유지시키기 위해 올리브형/너트형 장치 배열(110)을 수용한다.From FIG. 2 and also as can be seen with reference to FIG. 1, the
밀봉 벽(22)은 비자기 재료로 형성된다. 벽(22)을 통해 그리고 대향 면에 대항하여 신호를 보내기 위해, 적절한 초음파 송신기를 형성하는 기술이 공지되어 있다. 본질적으로, 제어기(38)는 복귀된 신호를 분석함으로써 증기 또는 가스의 기포가 펌프 유체 내에 존재하는지를 결정할 수 있을 것이다. 이러한 프로브를 제공하기 위한 기술이 공지되어 있지만, 이러한 프로브는 본 발명의 비매설식 방식으로 이용되지는 않았다.The
본 발명의 실시예가 기재되었지만, 당업자라면, 본 발명의 범주 내에서 특정 변경이 가능하다는 것을 인지할 것이다. 이러한 이유로 인해, 첨부된 특허청구범위는 본 발명의 실제 범위 및 범주를 결정하도록 연구되어야 한다.While embodiments of the invention have been described, those skilled in the art will recognize that specific modifications are possible within the scope of the invention. For this reason, the appended claims should be studied to determine the true scope and scope of the invention.
