Embodiment 1

[0033] Such as Figure 1-3 As shown, the pump body 1 and the external suction pipe 12 are included, and two volute chambers 2 are arranged in parallel in the pump body 1, and the bottom of each volute chamber is respectively provided with a suction port 3, and the suction port 3 communicates with the external suction pipe 12; each Water pump impellers 5 are respectively installed in the volute, and the water pump impellers 5 are connected with the motor 10 through the pump shaft 11, and the motor 10 is arranged above the pump body 1; an output pipe 4 is provided on the pump body 1, and the output pipe 4 is connected to each worm The chambers 2 are all connected; the output pipe 4 is provided with a vacuum interface 7, which is airtightly connected with one end of the suction pipe 8, and the other end of the suction pipe 8 is connected with the vacuum turbine 9; outside the pump body 1, the volute chamber 2 radially install the support plate 6 at the center line.

Embodiment 2

[0035] Such as Figure 4 As shown, the volute chamber is arranged as four cores connected in parallel, the output pipe 4 is arranged as two, and other structures are the same as those in Embodiment 1.

Embodiment 3

[0037] Such as Figure 5 As shown, the volute chamber is arranged as three-core single-row combination, and other structures are the same as in Embodiment 1.

[0038] Start-up and running process of the present invention are as follows:

[0039] 1. Start the vacuum turbine, the vacuum turbine sucks out the air in the volute of the pump body through the suction pipe of the vacuum turbine airtightly connected with the outlet of the pump body, and the low-level water enters the volute chamber of the pump under the action of atmospheric pressure .

[0040] 2. Start the motor, the motor drives the vacuum turbine to close, the motor drives the impellers of each water pump to rotate simultaneously, and sends the water pressure sucked by each volute to the outlet shared by each volute for output.

Abstract

The invention relates to a turbine parallel multiple-suction single-discharge vertical-type lifting pump, which can be also called a radial split large-scale single discharge pump. The pump can suck water by using a built-in vacuum turbine, and the bottom of the pump body is provided with a plurality of suction ports. The lifting pump comprises a pump body and an external suction pipe, wherein at least two spiral housings are arranged in the pump body, and the suction ports are respectively arranged under the spiral housings; a water pump impeller is arranged in each spiral housing and is connected with a motor through a pump shaft; the pump body is provided with an outlet pipe, and the outlet pipe is communicated with each spiral housing; and the outler pipe is provided with a vacuum interface, the vacuum interface is airtightly connected with one end of an air suction pipe, and the other end of the air suction pipe is connected with the vacuum turbine. The invention has the advantages of high suction performance, stable operation and convenient maintenance; and the pump can be installed above the liquid level, thereby breaking through the tradition that a large-scale lifting pump must be installed below the liquid level, and realizing the revolution of installing the large-scale lifting pump above the liquid level.

Description

technical field [0001] The present invention relates to a pump, in particular to a radially split large-scale single-discharge pump which utilizes a self-configured vacuum turbine for water diversion. The bottom of the pump body is provided with multiple suction ports. It can also be called a turbine parallel multi-suction pump. Single discharge vertical lift pump. Background technique [0002] Large lifting pumps are widely used in factories, mines, urban water supply and drainage, seawater lifting, and can also be used in power stations, large-scale water conservancy projects, farmland irrigation and drainage, etc. [0003] At present, the large-scale lift pumps widely used at home and abroad include double-suction split pumps, single-stage single-suction submersible pumps, mixed-flow pumps, axial-flow pumps, and vertical diagonal-flow pumps. The applications of the above-mentioned large-scale lift pumps are as follows: point description: [0004] 1. The double-suction s...
