Submersible suspended semi submersible vertical turbine pump with jet discharge device

A semi submersible vertical turbine pump with a jet discharge device, comprising an inlet section, radial guide vanes, middle section, space guide vanes, protective pipe, connecting pipe, transmission shaft, discharge pipe, jet pipe, balance pipe, water level detection probe, and submersible solenoid valve. The inlet section, radial guide vanes, middle section, and space guide vanes are combined and connected by tightening bolts to form the pump chamber of the water pump; The pump chamber and the impeller, impeller nut, positioning ring, pump shaft, and mechanical seal set inside the pump chamber are assembled together to form a pressure reducing chamber. This technical method is ingeniously designed and has good performance, completely solving the sealing problem of the existing rolling bearing structure space guide vane liquid suspended semi submersible vertical turbine pump and the problem of air expansion caused by the operation of bearings and shaft seals that cannot be discharged; It can enable the water pump to achieve automatic circulation and drainage function, extend the service life of mechanical seals and rolling bearings, improve the safety and reliability of the pump unit and the service life of the pump unit, and reduce the maintenance cost of the water pump.

Technical requirements: 1. A semi submersible vertical turbine pump with a jet discharge device, comprising an inlet section, radial guide vanes, middle section, space guide vanes, protective pipes, connecting pipes, transmission shafts, discharge pipes, jet pipes, balance pipes, water level detection probes, and submersible solenoid valves. The pump is characterized in that the inlet section, radial guide vanes, middle section, and space guide vanes are combined and connected by tension bolts to form the pump chamber of the water pump; The pump chamber and the impeller, impeller nut, positioning ring, pump shaft, and mechanical seal set inside the pump chamber are assembled together to form a pressure reducing chamber.
