Abstract
Description
Claims (9)
- 펌프실(2)로부터 연결되는 배출구가 두개의 배출관(6,7)로 돼 있으며, 이 분기점(8)에 조절벤틸(9)이 달려 있어, 교대로 한 배출관을 열고 다른 배출관을 폐쇄시키는데, 배출구내의 압력강하를 0에 가까운 값이나 음의 값을 가지게 하여 조절벤틸(9)을 자동으로 변위케 하는 것을 특징으로 하는 원심펌프.
- 제1항에 있어서, 조절벤틸(9)의 벤틸변위장치(10), 특히 한개의 판막(10)이 압력의 강하에 의해 처음 폐쇄되는 끝 위치로 부터 두번째 닫히는 끝위치까지 움직일수 있다는 것을 특징으로 하는 원심펌프.
- 제1항에 있어서, 조절벤틸(9)의 벤틸변위장치(10), 특히 한개의 판막(10)이 압력의 강하에 의해 한 폐쇄되는 끝위치로 부터 압력의 상승이 없이 두번째 폐쇄되는 끝위치로 움직일 수 있는 위치에 이를 수 있다는 것을 특징으로 하는 원심펌프.
- 제1항 내지 제3항중 어느 한 항에 있어서, 압력강하, 특히 펌프의 멈춤시 그리고 이후 주회전 방향으로의 펌프 재가동시 벤틸변위장치, 특히 판막(10)이 항상 같은 배출관을 막고 있는 위치에 있다는 것을 특징으로 하는 원심펌프.
- 제1항 내지 제4항중 어느 한 항에 있어서, 펌프의 회전륜(3)이 대부분 항상 같은 주회전 방향으로 작동되고 조절벤틸(9)의 작동시에만 회전륜이 단시간 동안 반대방향으로 회전하는 것을 특징으로 하는 원심펌프.
- 제1항 내지 제5항중 어느 한 항에 있어서, 압력강하시 벤틸변위장치(10)를 적어도 다른 끝 위치의 방향으로 중간 이상 움직이게 하여 벤틸변위장치가 펌프의 새로운 수압에 의해 다른쪽의 끝 위치로 움직일 수 있도록 할 수압식, 유압식, 전자식 혹은 물리적 도구를 갖추는 것을 특징으로 하는 원심펌프.
- 제6항에 있어서, 그 도구가 태엽, 특히 스프링 태엽을 가지는 것을 특징으로 하는 원심펌프.
- 제6항 또는 제7항에 있어서, 그 도구가 한 스프링장치를 가지는 것을 특징으로 하는 원심펌프.
- 제6항 또는 제7항에 있어서, 그 도구가, 벤틸변위장치를 가격하여 누름으로써 펌프 내 혹은 배출구상의 배출관 내에서 작동이 가능케 할 수 있는, 한개의 수압식 실린더를 가지고 있다는 것을 특징으로 하는 원심펌프.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
