Problems solved by technology

The traditional multi-stage centrifugal pump design adopts the way that the impellers are arranged one by one. The pump will generate axial force during use. The balance force is usually balanced by a balance plate or a balance drum mechanism, but because the balance force cannot be completely eliminated , the balance mechanism of the pump will always wear during use, which will lead to wear of other rotor parts, thus affecting the normal service life of the pump. At the same time, because the parts of the balance mechanism are vulnerable parts, they need to be replaced frequently, which increases the user's equipment Repair fees

Embodiment Construction

[0012] like figure 1 Among them, an axial force self-balancing multistage centrifugal pump includes a pump body 17 and tension bolts 16, the first-stage impeller 2 is installed in the front section 3 of the pump body 17 through a shaft 15, a plurality of left impellers 4 and a plurality of right The impellers 10 are symmetrically installed on the shaft 15, a plurality of left impellers 4 are installed in the front pump chamber 5, a plurality of right impellers 10 are installed in the rear pump chamber 18, the front section 3 communicates with the front pump chamber 5, and the front pump chamber 5 is replaced by The flow passage 13 communicates with the rear section 14 , the rear section 14 communicates with the rear pump chamber 18 , and the rear pump chamber 18 communicates with the discharge section 8 .

[0013] When the total number of impellers in the front pump chamber 5 and the rear pump chamber 18 was an odd number, the many first-stage impellers were the left impeller ...

Abstract

The invention discloses an axial force self balancing multistage centrifugal pump. The self balancing of impellers in the axial direction is realized by arranging the impellers in a pump body in a symmetrical mode, namely, the axial force generated by the impellers at different levels cancels out each other, thus reducing the mechanical friction generated in the running process of the multistage centrifugal pump owing to the axial force, prolonging the no failure operation time of the centrifugal pump and reducing the equipment maintenance cost of users.

Description

technical field [0001] The invention relates to a multistage centrifugal pump, in particular to an axial force self-balancing multistage centrifugal pump. Background technique [0002] There are many types of pumps, which can be divided into vane pumps, positive displacement pumps and other types of pumps according to their working principles. Centrifugal pumps are a kind of vane pumps. Compared with single-stage centrifugal pumps, multi-stage centrifugal pumps have a wider range of applications , the market needs a larger share. The traditional multi-stage centrifugal pump is designed with the impellers arranged one by one. The pump will generate axial force during use. The balance force is usually balanced by a balance disc or a balance drum mechanism. However, the balance force cannot be completely eliminated. , the balance mechanism of the pump will always wear during use, which will lead to wear of other rotor parts, thus affecting the normal service life of the pump. ...
