[0002] Large axial flow pump is a powerful and widely used liquid conveying equipment, which plays an important role in people's production and life. In drainage projects, it can be used for water discharge and circulating water treatment; in agricultural irrigation, it can improve farming efficiency and reduce manpower input; in mining, seawater lifting and other applications, this kind of industrial equipment is also needed. Especially in areas with high terrain, due to the lack of water, large axial flow pumps can use their powerful water lifting capacity to transport water to where it is needed.

[0003] The existing large axial flow pumps equipped with only one outlet have limited the flexibility and efficiency of their application scenarios to a certain extent. When it is necessary to supply water to two water surfaces at the same time, or to discharge the accumulated water through two ditches, two ordinary axial flow pumps are usually required to work at the same time, resulting in high operating costs and high energy consumption. In addition, two pumping stations or two foundations require more land area, increasing construction costs. In addition, when ordinary axial flow pumps are installed, if the installation is unstable, it may cause vibration and noise during operation, and may also cause the performance of the axial flow pump to decline and fail to meet the use requirements.
