摘要： In an impeller 11, an inlet portion and an outlet portion are provided at one end side and the other end side in the axial direction, respectively. An inlet 29 is formed in the lower part of the inlet portion, and an outlet is formed in the side face of the outlet portion. The inlet portion and the outlet portion are partitioned by a flange portion 40. The impeller 11 includes a primary vane 36 and a secondary vane 38. The primary vane 36 defines a spiral primary channel 35 that connects the inlet 29 and the outlet. The secondary vane 38 is formed in a shape that a part of the outer periphery of the outlet portion is gouged inward so as to define a secondary channel 37 connected to the primary channel 35 and extending circumferentially around the outer periphery.

摘要： An example impeller includes: an impeller body in which an internal channel is formed, the internal channel extending inside the impeller body in a direction of a rotation axis spirally about the rotation axis to connect an inlet and an outlet; and at least one centrifugal vane provided in the impeller body. The internal channel including the inlet and the outlet has a predetermined passage diameter. An external channel is formed so as to continue to the outlet and go around the circumferential surface of the impeller body, the external channel being defined by the centrifugal vane and being recessed inward in the radial direction from the circumferential surface of the impeller body. At least a part in a flow direction of the external channel has a channel width in the direction of the rotation axis smaller than the width of the outlet.

摘要： A centrifugal pump impeller 11 includes an impeller body in which an inner channel 35 is formed, and a single centrifugal vane 37 provided in the impeller body so as to have a leading edge at an outlet and a trailing edge at a predetermined point of an outer periphery of the impeller body. The centrifugal vane 37 is designed so that the area of an outer channel 36, which is defined by the centrifugal vane 37, in an angle range of 270° in a peripheral direction from the trailing edge of the centrifugal vane 37 to the total area of the impeller body surrounded by the outer periphery of the impeller body is less than 0.3.
