Abstract
Description
Claims (8)
- 펌프실(2)로부터 연장하여 두개의 배출관(6,7)으로 분기하는 배출구 및 하나의 배출관을 선택적으로 개방하고 다른 배출관을 폐쇄하는 분기점(8)내에 위치되어 있는 전환 밸브(9)를 구비하고 있는 원심 펌프에 있어서, 밸브 조절 부재(10)은, 압력이 변화함에 따라서, 하나의 배출관(6,7)을 폐쇄하는 제1단부 위치로부터 반대로 다른 배출관(7,6)을 폐쇄하는 제2단부 위치로 전환시킬 수 있도록 구성되어 있고, 압력의 변화는 펌프의 멈춤에 의해서 생기는 압력 강하인것을 특징으로 하는 원심펌프.
- 제1항에 있어서, 상기 펌프의 멈춤은 회전 방향의 변화에 의해서 이루어지는것을 특징으로하는 원심 펌프.
- 제1항에 있어서, 상기 전환 밸브(9)의 상기 밸브 조절 부재(10)는 판막인 것을 특징으로 하는 원심 펌프.
- 제1항에 있어서, 상기 펌프는 바람직한 주된 회전 방향을 가지고 있는 것을 특징으로하는 원심 펌프.
- 제1항에 있어서, 수압, 공기압, 전기 및/또는 기구적 증가 수단들이 제공되어 있는데, 이는, 압력이 떨어질 경우, 상기 밸브 조절 부재(10)를 다른 단부 위치의 방향으로 중앙 위치를 넘는 어느 정도의 거리로 이동시키는 것을 특징으로하는 원심 펌프.
- 제5항에 있어서, 상기 수단은, 스프링을, 특히 탄성 스프링, 포함하고 있는것을 특징으로 하는 원심 펌프.
- 제5항에 있어서, 상기 수단은 오보-센터 장치를 포함하고 있는 것을 특징으로 하는 원심 펌프.
- 제5항에 있어서, 상기 수단은, 상기 밸브 조절 부재상에 작용하여서 상기 펌프내 및/또는 상기 배출관내/배출구에서의 압력에 의해서 작동될 수 있는 유압 실린더를 포함하고 있는 것을 특징으로 하는 원심 펌프.
