Horizontal pipeline pump

As an important form of centrifugal pump, double-suction pump is widely used in engineering because of its high head and large flow rate. The impeller of this pump type is actually composed of two back-to-back impellers, and the water flowing out of the impellers flows into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same impeller outer diameter; the pump casing is horizontally opened, 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 the inlet and outlet pipes; the impeller structure of the double-suction pump is symmetrical, there is no axial force, and the operation is relatively stable.
