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

[0082] see Figure 7 , Figure 7 It is a three-dimensional structural schematic diagram of the second embodiment of the prefabricated pumping station unit of the present invention. see Figure 7 , the second embodiment of the prefabricated pump station unit of the present invention is the same as Figure 1 to Figure 4 The main differences of the first embodiment shown are:

[0083] The inner cylinder 12 is in the shape of a cone as a whole, and has a large end with a larger diameter and a small end with a smaller diameter, wherein the end with a larger diameter is located inside the outer cylinder 11 . When the fluid flows downward along the inner wall of the cone-shaped inner cylinder 12, the flow state of the fluid will be further homogenized.

[0084] Other structures of the second embodiment of the prefabricated pumping station unit are basically the same as those of the first embodiment, and will not be repeated here.

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 and a wellbore installed inside the pump station body. The pump station body comprises an outer cylinder and an inner cylinder; the outer cylinder comprises an outer cylinder bottom and an outer peripheral wall installed on the outer cylinder bottom, wherein a submerged pump is installed on the outer peripheral wall; the inner cylinder comprises an inner peripheral wall; a top end of the inner cylinder is provided with an opening; an upper end of the inner cylinder is installed on the outer cylinder bottom of the outer cylinder in a penetrating mode and is positioned inside the outer cylinder; the rest part of the inner cylinder is positioned outside the outer cylinder; a circulation space is formed by a partial inner peripheral wall, a partial outer peripheral wall and the outer cylinder bottom. The fabricated pump station unit has good current stabilization and guiding performance so that the state of flow entering suction opening of the submerged pump is uniform, therefore good condition for water inlet is provided for the submerged pump and operation stability of the submerged 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 ...
