Portable transshipment cushioning mining double-suction multistage pump

Abstract

The invention discloses a portable transshipment cushioning mining double-suction multistage pump. The portable transshipment cushioning mining double-suction multistage pump comprises a mounting seat, a cushioning cavity is formed in the top side of the mounting seat, a disc is clamped in the cushioning cavity, a silencing box is fixedly connected to the top side of the disc, and a pump body is fixedly mounted in the silencing box. A support is fixedly installed in the center of the bottom of an inner cavity of the cushioning cavity, a clamping ball is fixedly installed on the top side of the support, a clamping groove is formed in the bottom side of the center of the disc, the clamping ball is movably connected with the clamping groove in a clamped mode, and a plurality of springs are fixedly installed on the bottom side of the disc and distributed with the clamping groove as the center. A bottom plate is movably connected to the bottom of the mounting seat, four sets of moving wheels are fixedly mounted on the bottom side of the bottom plate, a telescopic pull rod is movably connected to the left side of the mounting seat, and a handle is fixedly connected to the left end of the telescopic pull rod. The portable transshipment cushioning mining double-suction multistage pump has the effect of damping the pump body and is convenient to move and transport.

Description

Technical field: [0001] The invention relates to the field of double-suction pumps, in particular to a double-suction multi-stage pump for shock-absorbing mining that is portable and transportable. 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 inst...

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 transport. The invention provides a portable and transportable mine-use double-suction multi-suction stage pump
