路構成。 A suction cover 3 made of the same material is superimposed on the lower surface of the pump casing 1 made of rubber or a material equivalent to this, and a pump suction port 4 is opened in the center of the suction cover 3. A protrusion 5 that approaches the bottom plate 7 (described later) is disposed on the lower surface of the periphery, and a peripheral portion of the bottom plate 7 that forms the lower bottom surface of the annular strainer 6 that fits with the outer peripheral surfaces of the pump casing 1 and suction cover 3 is provided. At the same time, there is provided a stepped portion 8 which is raised upward and comes into contact with the peripheral portion of the lower surface of the suction cover 3, and the remaining portion thereof is spaced apart from the lower surface of the suction cover 3 at a constant distance S.
The pump casing 1 and the suction cover 3 have recesses 9 spaced apart from the inner peripheral surface of the peripheral wall of the annular strainer 6 at key points on the outer peripheral surfaces of the pump casing 1 and the suction cover 3. Place 9
A large number of through holes 10 are arranged to communicate with the through holes 10.
A suction path structure for a vertical submersible pump, characterized in that a suction path 12 is formed from a recess 9 communicating with the pump through the lower surface of a suction cover 3 to a pump suction port 4.
