mechanical engineering; pumps. SUBSTANCE: pump has split housing, impeller arranged in housing and consisting of disk with curved blades. Inlet branch pipe is divided into two intake channels whose outlets are spaced in direction of impeller rotation. Partitions between intake channels at outlet to impeller from its center to housing are inclined in direction of impeller rotation. Impeller is of conical propeller shape. Inlet diameter of impeller is smaller that its outlet diameter. Housing, in place of installation of impeller, is made is form of upward diverging truncated come smoothly changing into sphere constructing at outlet. Blades are installed on impeller with concave part facing handled liquid. Such design provides low resistance of handled liquid at impeller inlet. EFFECT: effective transfer of viscous liquids, such as fuel oils. 4 cl, 6 dwg |
