Abstract
The utility model provides a self-balancing multistage submerged pump, which consists of an inlet cover, a water outlet end, a tension bolt and one or more first-stage impellers, wherein first-stage impellers are mounted on a shaft and between the inlet cover and the water outlet end, a secondary suction end is arranged on the other side of the water outlet end, one or more two-stage impellers are arranged between the secondary suction end and the water outlet end, and the amount of the two-stage impellers is equal to that of the first-stage impellers. The self-balancing multistage submerged pump adopts two suction ends and one water outlet end, the impellers are distributed on two sides of the water outlet end symmetrically, the number and the size of the impellers are identical but rotation directions thereof are reversed, so that forces stressed on the shaft are equal in strength but reverse in direction and act on the shaft in a balancing state. Accordingly, the submerged pump can be balanced axially by the aid of self structure rather than by any balancing drums, and is simple in assembly and durable in use.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of self-balancing type multi-level submerged pump.
Background technique
The structure of traditional type multi-level submerged pump is a suction side now, an exhaust end, impeller, middle-end are contained between suction side and the waterexit end, be that impeller is in the side of end that spues, axial force is by the impeller, Balance disc (drum) and the thrust-bearing balance that are contained on the axle, and shell only bears inlet pressure, and assembly process is trouble, and equilibrium gap is difficult for controlling, and is prone to the phenomenon of equilibrant difference seize.
Summary of the invention
The utility model provides the self-balancing type multi-level submerged pump, has solved the shortcoming that traditional Under Water Pumps equilibrium gap is difficult for controlling, being prone to equilibrant difference seize.
The technical solution of the utility model is achieved in that the self-balancing type multi-level submerged pump, constitute by inlet cover, waterexit end, stretching screw and the one-level impeller between inlet cover and waterexit end that is installed on the axle, the waterexit end opposite side is provided with secondary suction side, is provided with the sencond stage impeller identical with the one-level impeller between secondary suction side and the waterexit end;
The quantity of one-level impeller is 〉=1;
The quantity of sencond stage impeller is identical with the quantity of one-level impeller.
The beneficial effects of the utility model are: the utility model adopts two suction sides, a waterexit end, the both sides that impeller is distributed in the waterexit end are symmetry status, its impeller number, big or small identical, switched in opposite, pretending the power that is used on the axle also is equal and opposite in direction, direction is opposite, and therefore the power that acts on the axle is state of equilibrium, so the pump of this structure does not carry out balance with balancing drum, but just can carry out axial force balance by himself structure, not only assemble simple and durable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Part explanation: 1, inlet cover, 2, the one-level impeller, 3, the waterexit end, 4, sencond stage impeller, 5, stretching screw, 6, secondary suction side, 7, axle.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: the self-balancing type multi-level submerged pump, include flap 1, waterexit end 3, stretching screw 5 and be installed in the one-level impeller 2 inlet cover 1 and waterexit end 3 between of axle on 7, waterexit end 3 opposite sides are provided with secondary suction side 6, between waterexit end 3 and secondary suction side 6, be provided with the sencond stage impeller 4 identical with one-level impeller 2, the quantity of sencond stage impeller 4 and one-level impeller 2, size shape is identical, be symmetry status, switched in opposite, the power that acts on the axle is state of equilibrium, just can carry out axial force balance by himself structure.
