Abstract
Official abstract text for this publication.
An impeller in embodiments, as an example, includes a base plate, and a shroud including a plurality of blade members fixed to the base plate, wherein a plurality of the blade members are provided so as to stand and are arranged with intervals in a circumferential direction on a face portion of the shroud, the face portion facing the base plate, a plurality of groove portions for mounting each of a plurality of the blade members are formed on the base plate, and a plurality of the groove portions are configured to mount each of the blade members included in a plurality of kinds of the shrouds in which at least one of an arrangement of the blade members and a number of the blade members is different from each other.
First claim
Opening claim text (preview).
1 . An impeller comprising: a base plate; and a shroud including a plurality of blade members fixed to the base plate, wherein a plurality of the blade members are provided so as to stand and are arranged with intervals in a circumferential direction on a face portion of the shroud, the face portion facing the base plate, a plurality of groove portions for mounting each of a plurality of the blade members are formed on the base plate, and a plurality of the groove portions are formed so that each of the blade members of a plurality of kinds of the shrouds different in at least one of arrangement and number of the blade members can be mounted. 2 . The impeller according to claim 1 , wherein the base plate includes, as a plurality of the groove portions, first groove portions and second groove portions respectively associated with two kinds of the shrouds in which arrangements of the blade members are different from each other, and, when blade members applying centrifugal force to fluid in conjunction with a rotation of the base plate in one direction are defined as first blade members, and blade members applying centrifugal force to fluid in conjunction with a rotation of the base plate in a direction opposite to the one direction are defined as second blade members, the first groove portions are formed at positions to mount each of the first blade members, and the second groove portions are formed at positions to mount each of the second blade members. 3 . The impeller according to claim 1 , wherein the base plate includes, as a plurality of the groove portions, first groove portions and second groove portions respectively associated with two kinds of the shrouds in which arrangements of the blade members are different from each other, and inclination angles of the first groove portions and the second groove portions relative to a reference line are different from each other, the reference line being a straight line extending outward from a center of the base plate in a radial direction. 4 . The impeller according to claim 2 , wherein each of the first groove portions and each of the second groove portions are independently formed without intersecting with each other. 5 . The impeller according to claim 2 , wherein each of the first groove portions and each of the second groove portions are formed with intersecting with each other. 6 . The impeller according to claim 3 , wherein each of the first groove portions and each of he second groove portions are independently formed without intersecting with each other. 7 . The impeller according to claim 3 , wherein each of the first groove portions and each of the second groove portions are formed with intersecting with each other.
