Visual guide vane body device for automatic dredging of vertical axial flow pump

Abstract

The invention discloses an automatic dredging visible guide vane body device of a vertical axial flow pump. The automatic dredging visual guide vane body device of the vertical axial flow pump is simple in structure, convenient to clean and capable of improving efficiency. Comprising a pump body, a vertical pump shaft is arranged in the pump body, and a water guide bearing is arranged at the bottom of the pump shaft and located in a bearing socket of a guide vane body; the drainage assembly comprises a first calandria, a second calandria and a plurality of pipeline dredging machines, the first calandria is annular, the second calandria is a vertically-arranged vertical pipe, the pump body is located in an annular opening of the first calandria, the second calandria is communicated with the first calandria, and the pipeline dredging machines are annularly and evenly distributed on the outer side of the pump body; the pipeline dredging machine is arranged above the first rack pipe through a support, a main pipe of the pipeline dredging machine penetrates through the pump body and extends into the bottom of the bearing socket of the guide vane body, and a branch pipe is arranged on the main pipe, located outside the pump body and communicated with the first rack pipe. The device is convenient to control, stable in operation, free of manual disassembly and cleaning, time-saving, labor-saving and capable of eliminating unit operation hidden dangers.

Description

technical field [0001] The invention relates to the field of large pump bodies, in particular to a visible guide vane body device for automatic dredging of vertical axial flow pumps. Background technique [0002] The Jiangdu Water Control Project is mainly composed of 4 large-scale Dianli pumping stations, 12 large and medium-sized sluices, power transmission and transformation projects, and drainage channels. The project integrates the functions of water pumping and drought resistance, waterlogging drainage, and flood discharge, and plays a huge social benefit. As a state-level water conservancy project management unit and a first-level unit of water conservancy safety standardization, while ensuring the safety of flood control and drainage in the Huaihe River and Yishusi River Basin in Jiangsu Province, it also undertakes industrial and agricultural production and waterlogging in 50 counties (cities, districts) in 7 cities in northern Jiangsu. The safety of domestic water...

Problems solved by technology

In order to avoid the recurrence of this problem, the four stations adopt periodic manual disassembly for sludge cleaning, which is time-consuming and laborious

Moreover, the pipelines have a certain degree of siltation in an average of about 2 months, which reduces the reliability.
