Space guide vane suspended semi submersible vertical turbine pump pressure reducing structure

The pressure reducing structure of a space guide vane suspended semi submersible vertical turbine pump includes a space guide vane, a pump shaft, a bearing assembly, a sealing assembly, a protective tube, a connecting tube, and a pressure reducing tube. The pump shaft is positioned inside the space guide vane through a bearing assembly; The spatial guide vanes, protective tubes, and connecting tubes are connected as a whole by bolts; The sealing component is positioned together with the pump shaft and spatial guide vanes through screws; The pressure reducing tube is placed on the spatial guide vane. There are pressure reducing sealing chambers and pressure reducing holes on the space guide vanes. This technical method has a simple structure, low production cost, easy installation and maintenance, and improves the sealing performance and service life of the sealing components. It effectively prevents the pressure of the liquid rising along the pump shaft, ensuring that the liquid does not enter the bearing components, protecting the bearing components and pump shaft, improving the performance and extending the service life of the pump unit.

Technical requirements: 1. A space guide vane suspended semi submersible vertical turbine pump pressure reducing structure, comprising a space guide vane, a pump shaft, a bearing assembly, a sealing assembly, a protective tube, a connecting tube, and a pressure reducing tube, characterized in that the pump shaft is positioned inside the space guide vane through a bearing assembly; The spatial guide vanes, protective tubes, and connecting tubes are connected as a whole by bolts; The sealing component is positioned together with the pump shaft and spatial guide vanes through screws; The pressure reducing tube is placed on the spatial guide vane.
