Structures Of Non-Positive Displacement Pumps
(AREA)
Abstract
Improvements in centrifugal pumps, of the type of those with the impellers impelled mounted on the shaft and rotating with the latter, characterized by the fact that in the aforementioned shaft, in the mounting areas of the impellers, conical surfaces are provided whose vertices are mutually opposite, while the complementary surfaces of the impellers are also conical, at least one of the conical surfaces of the shaft being formed by a sleeve arranged thereon with provision of axial movement during operation, in order to press the impellor impellers, against the corresponding conical surfaces of the tree.
