Self-balancing multi-stage axially split pump equipment

Abstract

The invention discloses self-balancing multi-stage axially split pump equipment which comprises a pump shell body, a pump shaft, a forward guide vane assembly and a reverse guide vane assembly, a supporting plate is arranged in the pump shell body and divides a pump cavity into a first cavity and a second cavity, a first baffle is arranged in the first cavity of the pump shell body, and a second baffle is arranged in the second cavity of the pump shell body. A second baffle is arranged in the pump shell body and the second cavity, a limiting block is arranged on the upper shell, the first baffle is arranged close to one forward guide vane assembly, and the limiting block is arranged close to one reverse guide vane assembly. The first baffle is arranged in the pump shell body to limit the forward guide vane assembly located in the first cavity, and the second baffle is arranged in a matched mode to reduce energy loss in the liquid conveying process; and then the limiting block is used for limiting the reverse guide vane assembly, so that deformation of the guide vane assembly caused by acting force applied to the guide vane assembly when the liquid flows in the pump cavity is avoided, the friction risk between the impeller and the guide vane assembly is reduced, and the service life of a product is prolonged.

Description

technical field [0001] The invention relates to the technical field of split pumps, in particular to a self-balancing multi-stage split pump equipment. Background technique [0002] Segmental multistage centrifugal pumps are extremely inconvenient for maintenance and overhaul due to structural limitations, and the balance disc device on the product will continue to wear over time, and the efficiency of the rotor components will drop significantly due to the forward movement of the rotor parts, etc. Disadvantages: The volute type multi-stage split pump will increase the difficulty of casting and processing the product due to the complexity of the flow channel. Both of the above two multistage centrifugal pumps will affect the stiffness of the shaft with the increasing number of impeller stages, reduce the stability of the product operation, and ultimately reduce the life of the bearings and shorten the life cycle of the product. [0003] Therefore, it is urgent to propose a ...
