Abstract
A radial force self-balancing structure of a water draining end of a multi-stage pump comprises a spiral volute A and a spiral volute B, wherein the spiral volute A and the spiral volute B are arranged in the water draining end, and are symmetric along a center line of the water draining end; an included angle between the spiral volute A and the center line of the water draining end is 180 degrees; and an included angle between the spiral volute B and the center line of the water draining end is also 180 degrees. The radial force self-balancing structure of the water draining end of the multi-stage pump is simple in structure and convenient to mount; guiding blades of a tail stage are omitted; the labor intensity is reduced; the maintaining cost is also reduced; and moreover, the radial force self-balancing structure can be popularized and applied, and has a high economical benefit and a high social benefit.
Description
Technical field
The utility model belongs to centrifugal pump technical field, particularly a kind of multistage pump waterexit end radial force self-balance structure.
Background technique
The multistage pump of prior art, when flow changes, when pump is worked under large flow or small flow, impeller and spiral case can not be harmonious, and inhomogeneous in impeller surrounding liquid flowing velocity and pressure distribution formed the radial force that acts on impeller.
For balance radial force, conventionally adopt final stage stator is set between impeller and waterexit end, the final stage stator of both sides is by 180 ° of methods that are arranged symmetrically with, although this structure has solved the equilibrium problem of radial force, but the degree of 180 between the final stage stator of both sides is difficult to guarantee, has increased the workload of adjusting; For guaranteeing the concentric centering of final stage stator of both sides, when final stage stator need to be changed because of wearing and tearing, need to change by 180 degree are symmetrical, increased maintenance cost.
Summary of the invention
The purpose of this utility model will solve the problems of the technologies described above.
The purpose of this utility model is achieved in that a kind of multistage pump waterexit end radial force self-balance structure, comprise spirality Crucible shell A, spirality Crucible shell B, spirality Crucible shell A and spirality Crucible shell B are arranged in waterexit end, it is characterized in that: described spirality Crucible shell A and the center line of spirality Crucible shell B and waterexit end are symmetrical and be mutually 180 degree and arrange.
The utility model is simple in structure, easy for installation, has saved final stage stator, has reduced labor intensity, has reduced maintenance cost, applies and has good economic and social benefit.
