Abstract
PURPOSE: To remove a low-pressure section from an impeller's surface without deteriorating function of the pump and to prevent occurrence of cavitation, by providing an opening which pierces front shroud gap on an intake side of the impeller and the impeller's vane front edge section.
CONSTITUTION: A gap 5 is formed by weir rings 3 attached to a front shroud 1a and a casing 4. The front shroud 1a is provided with a small gap 6 as depicted in the sketch and it is so formed as to pierce the gap 5 and the impeller 1's vane 1b's front edge section. By using this mechanism, flow of water conducted from an outlet e of the impeller 1 to the gap 5 is made to pass through the small gap 6 and jetted out to the vane 1b's front edge section, and therefore, low-pressure sections which locally occur on the vane's surface are eliminated and occurrence of cavitation is prevented.
