Description
Claims (3)
- 하나 이상의 베인과 중앙 허브로 구성된 임펠러와, 원통형 입구가 마련된 펌프 하우징을 포함하되, 전연부는 후퇴해 있으며 임펠러 축에 대해 대체로 수직인 평면에 배치되고, 하나 이상의 급송 홈은 베인에 대향하는 펌프 하우징 벽의 표면에 배치되며, 상기 홈은 상기 전연부 영역의 상류에 배치되고 입구로부터 출구쪽으로 이어지며 임펠러의 회전 방향으로 만곡되어 있는 하수 펌핑용 원심형 또는 반축류형 펌프에 있어서,상기 하나 이상의 홈을 관통하는 원통상의 단면에 있어서, 임펠러가 통과하는 측면에 펌프 하우징 표면과 상기 하나 이상의 급송 홈 사이에 완만한 천이부가 마련되고, 상기 홈의 경사부와 펌프 하우징 사이의 각도(γ)는 γ = arctan(Δz/(r·Δθ))로 정의되며,상기 Δz는 축방향 변위, 상기 r·Δθ는 접선 방향 연장부이며, 상기 각도(γ)는 2도 내지 25도 사이인 것을 특징으로 하는 펌프.
- 제1항에 있어서, 상기 하나 이상의 홈을 관통하는 임의의 원통형의 단면에 있어서, 상기 홈의 대향 표면은 대체로 수직으로 지향되고, 상기 표면은 대체로 타원형인 바닥으로 연속적으로 변환되는 것을 특징으로 하는 펌프.
- 제2항에 있어서, 타원형인 상기 하나 이상의 홈의 상기 바닥의 횡축의 길이는 적어도 상기 홈의 깊이의 2배인 것을 특징으로 하는 펌프.
