Abstract
PURPOSE: To enable removal of fine sand, thereby preventing suction of sand into the impeller, by a method wherein de Laval type, centrifugal separator rotated by the pump driving shaft in the water stream is provided on the intake side of the pump.
CONSTITUTION: Between the underwater motor 10 and the impeller 14, a de Laval type centrifugal separator 28, consisting of several numbers of thin, umbrella shaped disk superposed at the predetermined intervals and rotating incorporated with the pump driving shaft 12, is provided in the water passage on the intake side of the pump. With this constitution, when water containing sand is about passing through the layers of the disk of centrifugal separator 28 from outside to inside, water and sand revolve around the driving shaft 12 because the intervals among disks in layers are made small, and with the centrifugal function, the sand of large specific gravity is exhausted, but only water can passes through the water passage 30 which is in the inside circumferencial part of the separator. Accordingly, locking in the disks in layers of the centrifugal separator 28 by sand can be prevented, as well as fine sand can be discharged.
