する小形渦巻ポンプのインペラ。 It has a pump chamber whose both end surfaces are closed and closed, and whose circumferential surface is cylindrical, and an inlet is formed at the center of one bottom surface of the pump chamber, and a discharge port is formed at the periphery. At the same time, the pump chamber is equipped with a small-sized impeller having a blade body protruding from a disk boss integrally fixed to the motor shaft toward the bottom side where the inflow port is formed. In the centrifugal pump, the blade body is an arc blade set by an inlet angle on the center side and an outlet angle on the outer diameter side, and the gap between the tip edge of the blade body and the bottom surface of the pump chamber is 0.
2 mm to 1.0 mm, the inlet angle of the blade body is set in the range of about 50 degrees, and the outlet angle of the blade body is set in the range of about 30 degrees.
