摘要： An axial flow pump comprising a inner wall disposed in contact with the inside of a stator having winding, a rotor disposed inside the inner wall and adapted to be rotated upon energization of the winding, an axial flow blade formed on an outer periphery of the rotor spirally in a rotational axis direction of the rotor, and a flow path formed between the rotor and the inner wall and defined spirally in the rotational axis direction of the rotor by the axial flow blade. The inner wall is formed of non-magnetic metal and heat generated from the winding upon energization of the winding is transmitted through the inner wall to fluid flowing through the flow path, thereby enhancing the utilization rate of heat generated in the axial flow pump.

摘要： Disclosed is an axial flow pump including a combined impeller integrally formed of an axial impeller and a centrifugal impeller, the axial impeller being composed of a first cylinder on which a first groove is formed, the centrifugal impeller being composed of a second cylinder on which a second groove is formed. The second groove is smoothly connected with the first groove and a distance between a bottom surface of the second groove and a centerline of the second cylinder gradually increases to prevent turbulent flow of liquid which may occur at the connection point between first and second grooves thereby achieving a high pump performance and a decreased external size of the pump.

摘要： Inside a single casing the turbopump comprises a main shaft driven by a turbine, a secondary shaft coaxial with the main shaft, a low pressure impeller mounted on the secondary shaft to create a medium pressure flow which is brought back to flow parallel to the axis of the turbopump by a baffle and which is deflected through 180.degree. in a return channel so as to come back parallel to the axis of the turbopump towards a high pressure impeller mounted on the main shaft inside the secondary shaft. The entire HP flow formed by the HP impeller is output via the insides of curved hollow blades forming a portion of the LP impeller, this HP centrifugal flow thus establishes a driving torque for the LP impeller.

摘要： A pump for pumping liquids includes a casing formed by upper and lower casing parts secured together. The upper casing part houses a centrifugal rotor having blades which direct liquid to a volute and the lower casing part houses an axial lift impellor which supplies liquid to the centrifugal rotor by way of fixed blades. The lower casing part also houses a further rotor which induces flow of liquid through the pump inlet. The rotor is directly connected to a drive shaft and the centrifugal rotor and impellor are coupled to the shaft preferably through step up gearing.
