Problems solved by technology

[0004] The technical solution in this U.S. patent application is relatively complicated. Although the fluid power can be consumed to a certain extent through the baffle device, the flow state of the fluid becomes very uneven after passing through the multiple liquid outlets of the baffle device. A lot of turbulence, so this US patent application is not enough to improve the fluid flow regime

Embodiment approach 2

[0059] see Figure 7 , Figure 8 and Figure 9 , Figure 7 It is a schematic diagram of the three-dimensional structure of another embodiment of the prefabricated pumping station unit of the present invention, Figure 8 yes Figure 7 longitudinal sectional view of Figure 8 yes Figure 7 top view. The second embodiment of the prefabricated pump station unit of the present invention is the same as figure 1 , figure 2 and image 3 The main differences of the first embodiment shown are:

[0060] The pumping station body 1 includes a first cylindrical portion 11 , a tapered portion 12 and a second cylindrical portion 13 which are sequentially sealed and connected from top to bottom, wherein the cross-sectional size of the second cylindrical portion 13 is smaller than that of the first cylindrical portion 11 . The first tube part 11 and the second tube part 13 can be both cylinders, or can be tubes of other shapes; the tapered part 12 can be cone tubes or tubes of other ...

Abstract

The invention provides a prefabricated pump station unit and a water distribution unit. The prefabricated pump station unit comprises a prefabricated pump station body, a liquid inlet connected to the pump station body, a shaft arranged in the pump station body and a submersible pump disposed in the shaft. The pump station body comprises a first drum part and an increasingly-reducing part at the lower end part of the first drum part. The size of the cross section of the increasingly-reducing part is gradually smaller from the top to the bottom. The liquid inlet is arranged at the first drum. The prefabricated pump station unit and the water distribution unit have the following beneficial effects: the prefabricated pump station unit has the good flow-guide function so that fluids entering a liquid absorption port of the submersible pump become uniform in states; and favorable water inlet conditions are created for the submersible pump and stability of operation of the submersible pump is improved.

Description

technical field [0001] The present invention relates generally to a pumping station for conveying liquids, and in particular to a prefabricated pumping station unit and water distribution unit. Background technique [0002] With the development of urban construction, the amount of municipal rainwater and sewage is increasing, so there are various sewage treatment equipment, and pumping stations are one of them. [0003] US Patent Application Publication No. US 20080011372 discloses a prefabricated pump station unit comprising a floor, an enclosure fixed to the floor, and a plurality of submersible pumps installed in the enclosure. A liquid inlet and a liquid outlet are arranged on the surrounding wall. The fluid enters the prefabricated pump station unit through the liquid inlet, and flows out through the liquid outlet under the power provided by the submersible pump. Due to heavy rain and other reasons, the amount of fluid flowing into the prefabricated pump station unit ...
