Abstract
The utility model discloses a balanced plate for a multi-stage pump, comprising a plate body. The plate body is a cylinder with a through hole in the middle; a fillet is formed at the left side of the through hole in a chamfering way; a cylindrical slot is arranged at the right surface of the plate body; a plurality of horn holes are uniformly arranged at the internal side of the cylindrical slot at the external side of the through hole of the plate body; the horn openings of the horn holes face to the cylindrical slot; and the balanced plate is made of 2Cr13. The balanced plate has the advantages that the structure is simple, the manufacture is convenient, the stiffness and the strength are high, and the service life is long.
Description
Technical field:
The utility model relates to the multistage pump field, specifically is a kind of multistage pump balance plate.
Background technique:
The multistage sectional boiler feed pump is called for short the flimsy phenomenon of Equilibrator of (DG pump) existence in service, therefore the structural design of equalizing feature is very important, need analyze reason, size and the balance mechanism of axial force generation and propose solution, design rational equalizing feature, help to prolong the working life of pump.In order to improve the reliability of multi-stage pump axial force balance device, the structure that can adopt the associating of balance plate and Balance disc is that autobalance dish device comes balancing axial thrust.Multistage pump is under the situation that Balance disc and balance plate are close to, and the width of impeller outlet should be in the vane inlet width range.
The model utility content:
The purpose of this utility model provides a kind of multistage pump balance plate, improves multistage pump Equilibrator reliability, and balance plate and Balance disc co-ordinative construction realize that autobalance dish device comes balancing axial thrust.
The technical solution of the utility model is as follows:
A kind of multistage pump balance plate, comprise plate body, described plate body is the middle cylindrical body that is provided with through hole, the through hole left side is rounded down, the plate body right side is provided with cylindrical groove, it is characterized in that: the inboard of described plate body through hole outside cylindrical groove evenly is furnished with a plurality of bellmouth orifices, and the loudspeaker opening is towards cylindrical groove.
Described multistage pump balance plate is characterized in that: described balance plate material therefor is 2Cr13.
The utility model has the advantages that:
The utlity model has simple in structurely, easily manufactured, rigidity and intensity are good, the advantage of long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
A kind of multistage pump balance plate comprises plate body 1, and plate body is the middle cylindrical body that is provided with through hole 2, through hole 2 left sides are rounded down 3, the plate body right side is provided with cylindrical groove 4, and the inboard of plate body through hole 2 outside cylindrical grooves 4 evenly is furnished with a plurality of bellmouth orifices 5, and the loudspeaker opening is towards cylindrical groove 4.Described balance plate material therefor is 2Cr13.
