Problems solved by technology

Therefore, the use of axial flow pumps to create flow in river water will cause a lot of waste of electric energy and high operating costs.
In addition, due to the high power and high speed of the axial flow pump, the noise during operation is relatively large; and due to the high speed of the axial flow pump, the impeller will cause great damage to small organisms in the river water body during operation, which is not conducive to building Good water ecological environment

Embodiment 1

[0024] Embodiment one: see Figure 1-4 , a low-lift large-flow liquid delivery device, including a flow channel 2 composed of a bottom surface 11 and two side surfaces 10, and an impeller 1 arranged above the flow channel 2. The impeller 1 is composed of a rotating shaft 9 and ten uniformly arranged around the rotating shaft Consisting of two planar equal-length panels 8, the rotating shaft 9 is supported on the two sides 10 of the flow channel through the bearing 4 and the bearing seat 5, and the rotating shaft 9 is connected with a rotating driving device composed of a reduction device 6 and a motor 7 , the bottom surface 11 is provided with an arc surface 3 located below the impeller 1, the center of the arc surface 3 coincides with the center of the rotating shaft 9, the center angle of the arc surface 3 is equal to 60 degrees, and between the arc surface 3 and the web 8 A lower gap 12 is provided, a side gap 13 is provided between the side surface 10 and the web 8, a flex...

Embodiment 2

[0025] Embodiment 2: Other structures are the same as Embodiment 1, the difference is that the web 8 is a curved surface, and the bending direction of the curved surface is opposite to the rotation direction of the impeller 1 .

Embodiment 3

[0026] Embodiment 3: Other structures are the same as Embodiment 1, except that side plates (not shown) are arranged on both sides of the web 8 , and the rotational speed of the impeller 1 is 5 rpm.

Abstract

The invention discloses a low-lift and large-flow liquid conveying device, which comprises a flow channel composed of a bottom surface and two side surfaces and an impeller arranged above the flow channel. It is composed of evenly arranged multiple panels of equal length. The bottom surface is provided with an arc surface located below the impeller. The center of the arc surface coincides with the center of the rotating shaft. The center angle of the arc surface is greater than or equal to 360 degrees divided by the width of the panel. The number of pieces, the output speed of the rotating drive device is less than or equal to 60rpm. The advantage is that it adopts a low-speed design of less than 60rpm. Its large flow benefits from the water storage space formed between the impeller and each surface in the flow channel. The efficiency of the liquid delivery device is high. Low operating noise, friendly to the ecological environment.

Description

technical field [0001] The invention relates to a liquid conveying device, in particular to a liquid conveying device with low head and large flow. Background technique [0002] In the ecological management of urban inland rivers, due to the slow flow of water bodies, the problems of black and odorous water bodies, algae growth and sediment deposition in rivers have been aggravated. Improving the fluidity of water bodies will effectively alleviate these problems. [0003] One way to improve the fluidity of urban inland river water is to pump the water from one end of the river to the other end, so that the water in the river can flow. The characteristics of the water transport are 0.1-0.3m low head and 1-10m 3 / s large flow. However, in the current liquid conveying device, the water body conveying with low lift and large flow is mainly accomplished by the axial flow pump. Through the study of the main parameters of the axial flow pump, it is not difficult to see that the h...
