Description

Technical field:

[0001] The invention relates to the field of double-suction pumps, in particular to a portable mobile silt removal double-suction pump. Background technology:

[0002] As an important type of centrifugal pump, double-suction pumps are widely used in engineering due to their 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 is combined 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. The double-suction pump will vibrate when working, causing damage to its internal parts. A special shock-absorbing mechanism is required to cushion it. The double-suction pump is heavy and inconvenient to move and transport. During the operation of the double-suction pump, mud and sand may be mixed in the water, and the mud and sand need to be filtered. The mud and sand will accumulate during the filtration process, thereby affecting the flow rate. The filter mechanism needs to be cleaned regularly. The mud and sand are blocked by the screen at the outlet pipe and will remain on the inner wall, thereby affecting the operation of the pump. Summary of the invention:
