Portable movable silt-removing double suction pump

Abstract

The invention discloses a portable movable silt-removing double suction pump. The portable movable silt-removing double suction pump comprises a foundation, wherein a pump body is fixedly mounted at the top of the foundation, a bottom plate is movably connected to the bottom of the base, and a plurality of sliding wheels are fixedly mounted on the bottom side of the bottom plate; a base is fixedly mounted on the top of the foundation, the pump body is mounted on the base and comprises a water outlet pipe, the right end of the water outlet pipe is fixedly connected with a guide-out pipe, a first through opening is formed in the lower side of the right end of the water outlet pipe, a ring-shaped pipe is rotationally connected to the outer wall of the right end of the water outlet pipe, a second through opening is formed in the side wall of the ring-shaped pipe in a penetrating mode, a filter screen is obliquely mounted at the left end of the guide-out pipe, and a shovel plate is movably connected to the left side of the filter screen. The portable movable silt-removing double suction pump is simple in structure, convenient and practical, achieves buffering and damping, is convenient to transfer and can automatically clean silt.

Description

Technical field: [0001] The invention relates to the field of double-suction pumps, in particular to a portable mobile sand-removing double-suction pump. Background technique: [0002] As an important form of centrifugal pump, double-suction pump is widely used in engineering because of its high lift and large flow. The impeller of this type of pump is actually composed of two back-to-back impellers, and the water flow from the impeller is merged 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 outer diameter of the impeller; the pump casing is opened horizontally, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is beneficial to the arrangement and installation of the pump and the inlet and outle...

AI Technical Summary

Problems solved by technology

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 outer diameter of the impeller; the pump casing is opened horizontally, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is beneficial to the arrangement 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, and the double-suction pump will vibrate when it is working , causing damage to its internal parts, it is necessary to set up a special cushioning mechanism to cushion it. The double-suction pump is heavy and inconvenient to move and transfer. The water may be mixed with sand and mud during the work of the double-suction pump. The sand needs to be filtered. The sediment will accumulate during the filtering process and affect the flow rate. The filter mechanism needs to be cleaned regularly. The sediment will be blocked by the screen at the outlet pipe and will remain on the inner wall, thus affecting the work of the pump.
