Description

Technical Field

[0001] The utility model relates to the field of submersible axial flow pumps, in particular to a gate-type submersible axial flow pump. Background Art

[0002] Most of the existing submersible axial flow pump stations are built together with sluice gates (set in parallel) or arranged separately, but the pump stations need to be equipped with pump rooms and inlet and outlet pools to form a pumping device; taking the simplest submersible axial flow pump station without a plant as an example, see Figure 1 The figure shows an existing submersible pump station, including a pump room, inlet and outlet pools, flow-breaking facilities (flapping gates), inlet and outlet inspection gates, etc. It is obvious that the construction of a new submersible axial flow pump station requires a large amount of work, a long construction time, and requires a site for the pump station layout;

[0003] Regarding the patent of submersible axial flow pump, the Chinese patent with the authorization announcement number CN206916712U discloses an integrated structure of a submersible axial flow pump and a gate; the article includes using a sluice gate to realize the functions of self-drainage, self-induction, pumping and drainage or pumping and filling, greatly simplifying the hub layout and hydraulic structure, saving engineering land, reducing engineering volume and engineering cost, and shortening the construction period;

[0004] When the impeller on the submersible axial flow pump is discharging water, the water plants in the water will enter the interior of the submersible axial flow pump and entangle the impeller. The water plants will increase the water flow resistance, reduce the working efficiency of the pump, affect the pumping effect, and shorten the service life of the pump. Utility Model Content
