Claims (3)
- 판에 원주방향을 따라 배열되는 날개를 포함하는 원심형 임펠러에 있어서,판의 일면에 원주방향을 따라 수개 또는 수십개의 날개를 등간격으로 배열 고정시키되, 각 날개의 바깥쪽단이 판의 변들로부터 더 돌출 연장되도록 하고, 상기 판은 다각형 형상으로 제작된 다각형판으로 이루어진 것을 특징으로 하는 고풍량용 고효율 원심형 임펠러.
- 청구항 1에 있어서,상기 다각형판을 날개의 갯수와 일치하는 다각형의 형상으로 구비하되, 각 날개의 바깥쪽단이 다각형을 이루는 다각형판의 변들로부터 돌출 연장되는 시작점을 꼭지점으로 하여 다각형으로 제작된 것을 특징으로 하는 고풍량용 고효율 원심형 임펠러.
- 청구항 1 또는 청구항 2에 있어서,상기 다각형판은 각 날개의 바깥쪽 끝단을 하나로 이었을 때 생성되는 원의 직경(D)에 비하여 작은 0.88D의 기준원으로 정해진 다음, 기준원에 내접하는 다각형 형상으로 제작된 것을 특징으로 하는 고풍량용 고효율 원심형 임펠러.
