Abstract

본 발명은 축류펌프에 관한 것으로, 유로상에서 발생하는 여러 가지 손실에 따른 전체 수력손실을 저하시켜 성능을 향상시킬수 있도록 된 축류펌프를 제공하는 것을 그 목적으로 하며, 절결부(11a″)가 형성된 임펠러수용부(11a′)를 하류측에 구비하는 흡입관(11a)과, 상류측에 볼록한 융기부(11b′)가 형성되고 내부에 방사상으로 구성된 다수의 안내깃(13)을 구비하며 상기 흡입관(11a)의 임펠러수용부(11a′)단부에 결합되는 배출관(11b)과, 외주연상에 구동수단이 구비되고 상기 융기부(11b′)의 확개부위를 구성하도록 형성된 관형의 림(15)과 그 림(15)의 내측에 일체로 형성된 다수의 스크류형 날개(12c) 및 그 날개(12c)의 내측단부들이 연결되는 유선형의 임펠러보스(12b)가 구비되고, 상기 림(15)의 외주연이 상기 임펠러수용부(11a′)에 회전가능하도록 설치되어 상기 구동수단이 상기 임펠러수용부(11a′)상의 절결부(11a″)에서 외부의 동력을 전달받아 회전할 수 있도록 된 임펠러로 구성되는 것을 특징으로 함.The present invention relates to an axial pump, and an object of the present invention is to provide an axial pump capable of improving performance by lowering the total hydraulic loss caused by various losses occurring on the flow path, and an impeller having a cutout portion 11a ″ formed therein. The suction pipe 11a provided with the accommodating part 11a 'on the downstream side, and the convex ridge | bulb part 11b' formed in the upstream, are provided with the many guide blades 13 comprised radially inside, and the said suction pipe 11a is provided. Discharge pipe (11b) coupled to the end of the impeller (11a ') of the), and a tubular rim (15) and a figure formed with a driving means on the outer periphery and to form an extension of the ridge (11b') A plurality of screw-shaped wings 12c formed integrally with the inside of the 15 and streamlined impeller bosses 12b to which the inner ends of the wings 12c are connected are provided, and the outer circumference of the rim 15 is It is installed to be rotatable in the impeller accommodation part 11a '. Also it characterized in that the drive means is configured in a cutout (11a ") on the impeller receiving portion (11a ') to the impeller so as to rotate by receiving the external power.
