Abstract

A kind of balancing drum mechanism of pump, balancing drum is arranged in balancing drum set, also include countercurrent ring, the annular groove of radial direction is set along the outer circle wall of the balancing drum, the annular groove one end is the low-pressure area axial end of balancing drum, the countercurrent ring is installed in the annular groove, and countercurrent ring is fixed together by screw and balancing drum;O-ring is set between the countercurrent ring and balancing drum, to form static seal.The utility model compared with prior art have can prevent granule foreign enter balancing drum in, reduce balancing drum liquid leakage rate the advantages that.

Description

A kind of balancing drum mechanism of pump
Technical field
It the utility model is related to a kind of pump, more particularly to a kind of balancing drum part of pump.
Background technology
Balancing drum is the important equalizing feature on centrifugal multistage pump multiple centrifugal pump, and the equilibrium principle of balancing drum is high using balancing drum both sides The power of the formation of nip and low-pressure area obtains the radial load to higher-pressure region with area difference, with balance higher-pressure region to low-pressure area The radial load of self-assembling formation.The side for preventing the fluid leakage between balancing drum and balancing drum set to use in traditional balancing drum structure Method is to process labyrinth seal on the inside of balancing drum set to prevent medium from revealing, this structure not only sealing effectiveness unobvious and liquid In particle enter in labyrinth seal and easily damage sealing surface, cause the increase of labyrinth seal amount of leakage so as to causing balancing drum to lose Effect.
The content of the invention
The purpose of this utility model is the balancing drum component for providing a kind of pump, and the component can prevent granule foreign from entering In balancing drum, the leakage rate of balancing drum liquid is reduced.
The utility model is the improvement on the basis of existing balancing drum, and concrete technical scheme is as follows:
The utility model mainly includes balancing drum and balancing drum set, and the balancing drum is arranged in balancing drum set, also Include countercurrent ring, the annular groove of radial direction is set along the outer circle wall of the balancing drum, the annular groove one end is the low of balancing drum Nip axial end, the countercurrent ring are installed in the annular groove, and countercurrent ring is fixed together by screw and balancing drum;It is described inverse O-ring is set between stream ring and balancing drum, to form static seal.
As a preferred scheme of the present utility model, some oblique bar shapeds are set on the outer circle wall of the countercurrent ring Groove, to alleviate reverse power.
The utility model adds countercurrent ring between balancing drum and balancing drum set, when centrifuging pump operation rotation, countercurrent ring Rotated together with balancing drum.Countercurrent ring does work to the liquid between low-pressure side balancing drum and balancing drum set, makes low-pressure side balancing drum Fluid pressure increase between being covered with balancing drum promotes original low-pressure side medium to be flowed to balancing drum high-pressure side, so as to stop balance Leakage between drum and balancing drum set, and the gap that can be rinsed between balancing drum and balancing drum set prevents particle in liquid from entering.
The utility model has the following advantages that compared with prior art:
1st, it is capable of the radial load of efficient balance pump;
2nd, effectively prevent granule foreign from entering in balancing drum, ensure the normal operation of pump;
3rd, the liquid leakage amount of balancing drum is reduced, improves the operating efficiency of pump.
Brief description of the drawings
Fig. 1 is the utility model main view diagrammatic cross-section.
Fig. 2 is Fig. 1 A portions enlarged drawing.
Fig. 3 is countercurrent ring schematic front view of the present utility model.
Embodiment
Next just utility model is elaborated with reference to accompanying drawing
As shown in Figure 1, Figure 2 and shown in Fig. 3, balancing drum 1 is arranged in balancing drum set 2, along the outer circle wall of the balancing drum If the annular groove of radial direction, the annular groove one end is the low-pressure area axial end of balancing drum, and countercurrent ring 3 is installed in the annular groove, Countercurrent ring is fixed together by screw and balancing drum;O-ring 4 is set between the countercurrent ring and balancing drum, to form static seal; Some oblique bar-shaped troughs 5 are set on the outer circle wall of the countercurrent ring, to alleviate reverse power.

Claims (2)
