Abstract
The utility model relates to an auxiliary impeller and a slurry pump equipped with the auxiliary impeller. The auxiliary impeller comprises an A end surface and a B end surface which are parallel, wherein A end surface blades are arranged on the A end surface; B end surface blades are arranged on the B end surface of the auxiliary impeller; and the A end surface blades adopt hyperbolic blades. The surface, where the hyperbolic blades are arranged, of the auxiliary impeller throws a slurry liquid to the edge, and the blades on the other surface push the slurry liquid to the center, so that the sealing reinforcing function is realized, and the work efficiency of the slurry pump is improved.
Description
Technical field
The utility model relates to a kind of sub-propeller and the slag stock pump of this sub-propeller is installed.
Background technique
Existing sub-propeller as shown in Figure 1, only has A end face to have blade, and is straight line type, and during installation, A end face is by Stuffing box.Its working principle is: sub-propeller is in rotation process, and A end face blade drives slurries to run up, and due to the effect of centrifugal force, blade is thrown the slurries of packing seal end out, produces pressure difference, plays seal action.
Because A end face blade is straight line type, and only have one side to have, therefore seal badly, efficiency is low.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of sub-propeller and slag stock pump, the good sealing effect of sub-propeller, and the efficiency of slag stock pump is high.
The technical solution of the utility model is, a kind of sub-propeller, comprises parallel A end face and B end face, and is provided with A end face blade at A end face, and the B end face of described sub-propeller is provided with B end face blade, and A end face blade is hyperbolic-type blade.
Described B end face blade is spiral line type blade.
The utility model has also designed a kind of slag stock pump, comprise Stuffing box and impeller on transmission shaft, transmission shaft, above-mentioned sub-propeller is installed between the Stuffing box on described transmission shaft and impeller, and the A end face of sub-propeller is near Stuffing box, and the B end face of sub-propeller is near impeller.
Working principle of the present utility model is, sub-propeller is in rotation process, and A end face blade drives slurries to run up, due to the effect of centrifugal force, blade is thrown the slurries of packing seal end out, is thrown to the slurries at edge under the thrust of B end face blade, flow to axle central authorities, finally enter pump chamber.
Sub-propeller of the present utility model has the one side of hyperbolic-type blade that slurries are thrown to edge, and the blade of another side is shifted the slurries at edge onto center, plays like this effect of enhanced leaktightness, and improves the working efficiency of slag stock pump.

Fig. 1 is the structure of existing sub-propeller;
Fig. 2 is the structural representation of sub-propeller A end face described in the utility model;
Fig. 3 is the structural representation of sub-propeller B end face described in the utility model;
Fig. 4 is the structural representation of slag stock pump described in the utility model.
Embodiment
As shown in Figure 2 and Figure 3, a kind of sub-propeller, comprise parallel A end face 1 and B end face 3, and be provided with A end face blade 2 at A end face 1, the B end face 3 of sub-propeller is provided with B end face blade 4, and A end face blade 2 is hyperbolic-type blade, hyperbolic-type blade is to be hyperbola pattern at the outer edge of the A of sub-propeller end face 1; B end face blade 4 is spiral line type blade, and spiral line type blade is the helix pattern to B end face 3 center curvatures in the outer of B end face 3.
As shown in Figure 4, a kind of slag stock pump, comprises Stuffing box 7 and impeller 6 on transmission shaft 8, transmission shaft 8, and above-mentioned sub-propeller 5 is installed between the Stuffing box 7 on transmission shaft 8 and impeller 6, and the A end face 1 of sub-propeller 5 is near Stuffing box 7, and the B end face 3 of sub-propeller is near impeller 6.
