Abstract
PURPOSE: To improve the pump efficiency simply and econimically by a method wherein the current velocity at the maximum efficiency point of the pump is specified and as well as the specified vane width of an impeller is adopted to the height of a spiral casing in the design of the captioned pump equipped with a four or more pole motor.
CONSTITUTION: The factors which influence the performance of the torque flow pump are as follows: the figure and dimension of a pump casing, the figure of a throat and the figure of the impeller. Accordingly, in the design of the torque flow pump equipped with the four or more pole motor, the current velocity at the throat at the mximum efficiency point of the pump is rendered to be 70W100 by reducing the area of the throat within the pump casing 6, assuming the circumferential current velocity at the peripheral edge of the impeller 2 tobe 100. And yet the percentage ratio of the vane width of the impeller 2 to the height of the swirl casing 8 is rendered to be 50% or more to 100%.
