An impeller for a pump comprises a plurality of interconnected components (20, 23, 32) of an abrasive resistant material such as alumina supported on a resiliently flexible material such as polyurethane.doi:DE3566294 D1Deschamps John Alexander...
However, a drawback with such pumps known so far has been a rather low efficiency and a low lift curve. In the vortex pump of the invention, this problem is eliminated by providing the edges of the vanes with flanges essentially perpendicular to the vane surface....

The vane of the impeller in a high-speed or mixed-flow centrifugal pump for the conveying of liquids which contain high or low concentrations of strands or strips of vegetable, plastic or other material has a convex inlet edge whose curv... FW Stodder - US 被引量: 11发表: 1916年 ...
PURPOSE:To provide blades each having a high degree of accuracy in its area for reducing flow resistance, by integrally stacking sheet plates which are punched, in the axial direction of the pump for forming an impeller. CONSTITUTION:Punched several thin plates 31 are integrally stacked one upon...
Define impeller. impeller synonyms, impeller pronunciation, impeller translation, English dictionary definition of impeller. n. 1. One that impels, as a rotating device used to force a fluid in a desired direction under pressure. 2. A rotor or rotor blad
CONSTITUTION:A pump with a built in impeller is provided on the inside of a container 2 with a winged wheel 1 and a stator blade 6, and on the outside of the container 2 with a motor 5 driving the impeller 1. A projecting portion 7a is provided at the upper end portion of a ...
A Plexiglas laboratory pump with rectangular cross sections was tested and volute velocities were measured with a laser velocimeter. First, the pump with a four bladed rotating impeller was run at three flowrates. Second, the rotating impeller was replaced with a 32-bladed non-rotating impeller wi...
aliquid enters the pump suction and then the eye of the impeller.when the impeller rotates,it spins the liquid sitting in the cavities between the vanes outward and imparts centrifugal acceleration.as the liquid leaves the eye of the impeller a lowpressure area is created at the eye allowing...
New Progress with Impeller Pumps in Taiwan The impeller blood pump program began in the middle of the 1980s in Shanghai and was put on hold a few years later. It has been reactivated in Taipei since 1992 under the support of the National Council of Sciences, with a 5-year plan in......
