Suspended semi submersible vertical turbine pump with double suction structure

A suspended semi submersible vertical turbine pump with a double suction structure, comprising a connecting pipe. The upper end of the connecting pipe is connected to a water outlet bend pipe, and there is a shaft inside the connecting pipe. The upper end of the shaft is connected to a packing seal, a thrust bearing component, a motor seat, and a drive coupling. The lower end of the connecting pipe is sequentially connected to a guide housing, an inlet horn, and a lower filter screen. The lower end of the shaft is connected to a double suction impeller, and the double suction impeller is located inside the guide housing. The guide housing also has an upper filter screen, which is located above the double suction impeller. This technical method can effectively reduce the cavitation allowance of the pump, balance the axial force, reduce the bearing load, and improve the reliability of rotor operation.
