Technical field:

[0001] The invention relates to the field of pumps, and in particular to a self-cleaning double-suction pump. Background technology:

[0002] 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 merges 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.
