双吸泵扬程高，流量打，应用广泛

双吸泵作为离心泵的一种重要形式，因其具有扬程高、流量大等特点，在工程中得到广泛应用。这种泵型的叶轮实际上由两个背靠背的叶轮组合而成，从叶轮流出的水流汇入一个蜗壳中。

As an important form of centrifugal pump, double suction pump is widely used in engineering because of its characteristics of high head and large flow. The impeller of this pump type is actually composed of two back-to-back impellers, and the water flowing out of the impeller flows into a volute.

双吸泵具有如下一些特点：

The double suction pump has the following characteristics:

它相当于两个相同直径的单吸叶轮同时工作，在同样的叶轮外径下流量可增大一倍；泵壳水平中开，检查和维修方便，同时，双吸泵进出口在同一方向上且垂直于泵轴，利于泵和进出水管的布置与安装；双吸泵的叶轮结构对称，没有轴向力，运行较平稳。

It is equivalent to two single suction impellers with the same diameter working at the same time, and the flow can be doubled under the same impeller outer diameter; The pump casing is horizontally split, which is convenient for inspection and maintenance. At the same time, the inlet and outlet of the double suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the layout and installation of the pump and inlet and outlet pipes; The impeller of the double suction pump has symmetrical structure, no axial force and stable operation.
