Lifting vertical vortex pipeline pump

Abstract

The invention discloses a lifting vertical vortex pipeline pump. The lifting vertical vortex pipeline pump comprises a first motor and a pump body. The first motor and the body are fixedly connected through a bearing seat. A liquid outflow pipe and a liquid inflow pipe are arranged on the left side and the right side of the pump body respectively. A liquid outflow flange plate and a liquid inflow flange plate are arranged at the end of the liquid outflow pipe and the end of the liquid inflow pipe respectively. An impeller is arranged in the pump body. A lifting device is arranged at the bottom of the pump body. At least four supporting guide rods are symmetrically arranged on the periphery of the lifting device. The supporting guide rods are connected with the first motor through limiting mechanisms. One-way flow guide plates are rotationally connected to the inner wall of the liquid inflow pipe. Vortex generating bodies are arranged in the liquid outflow pipe. The lifting vertical vortex pipeline pump is simple in structure and high in practicality; the lifting device is arranged outside the pump body, the requirement of erection joint of pipelines of different heights can be met, the pipelines are prevented from being bent, and connecting accuracy and strength are improved; and liquid can flow in a vortex manner through the vortex generating bodies in the pump body, and pressure and speed in the liquid flowing process are increased.

Description

technical field [0001] The invention relates to a lifting vertical vortex pipeline pump. Background technique [0002] Pipeline pump is a kind of single-suction single-stage or multi-stage centrifugal pump. It is a vertical structure. Because the inlet and outlet are on the same straight line and the diameter of the inlet and outlet is the same, it looks like a section of pipeline and can be installed at any position in the pipeline. [0003] Since the installation position of the pipeline is sometimes not on the flat ground, the pipeline pump in the prior art can only be installed with the pipeline inclined or modified to connect with the pipeline pump, which not only reduces the construction efficiency, but also reduces the It is unstable when working, and because the inclined setting will cause the connection of the pipeline pump to overflow due to excessive local pressure, it is not suitable for the transportation of dangerous liquids; the pipeline pump in the prior art ...

[0003] Since the installation position of the pipeline is sometimes not on the flat ground, the pipeline pump in the prior art can only be installed with the pipeline inclined or modified to connect with the pipeline pump, which not only reduces the construction efficiency, but also reduces the efficiency of the pipeline pump It is unstable when working, and because the inclined setting will cause the connection of the pipeline pump to overflow due to excessive local pressure, it is not suitable for the transportation of dangerous liquids; the pipeline pump in the prior art can only realize the linear transportation of liquid, Therefore, the pressure will not fluctuate greatly, which is not conducive to transportation in some positions with large vertical height
