Submersible suspended semi submersible vertical turbine pump with vacuum drainage device

A semi submersible vertical turbine pump with a vacuum drainage device, consisting of an inlet section, radial guide vanes, and a middle section. The inlet section, radial guide vanes, middle section, and spatial guide vanes are combined and connected by tightening bolts to form the pump chamber of the water pump; The pump chamber is equipped with an impeller; The protective tube and connecting tube are respectively coordinated with the space guide vane, bearing seat, and pump support, and then connected and compressed with bolts to form an independent outlet chamber flow channel; There are three water level detection probes; There are two elbows; The exhaust pipe is installed and fixed on the exhaust hole, and the lower bearing cover is matched with the space guide vane and pressed tightly. Three water level detection probes are installed and fixed on the lower bearing pressure cover, and two elbows are installed on the bearing seat. The suction pipe is connected to one of the elbows to assemble the leakage collection device of the water pump together. This technical method is ingeniously designed to extend the service life of mechanical seals and rolling bearings, improve the safety, reliability, and service life of pump units, and reduce the maintenance cost of water pumps.

Technical requirements: 1. A semi submersible vertical turbine pump with vacuum drainage device, comprising an inlet section, radial guide vanes, middle section, space guide vanes, protective pipes, connecting pipes, exhaust pipes, water level detection probes, lower bearing covers, elbows, suction pipes, discharge pipes, and submersible solenoid valves, 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 is equipped with an impeller; The protective tube and connecting tube are respectively connected and tightened with bolts after cooperating with the spatial guide vanes, bearing seats, and pump supports, forming independent outlet chamber flow channels; There are three water level detection probes; There are two elbows; The exhaust pipe is installed and fixed on the exhaust hole, and the lower bearing cover is matched with the space guide vane and pressed tightly. Three water level detection probes are installed and fixed on the lower bearing pressure cover, and two elbows are installed on the bearing seat. The suction pipe is connected to one of the elbows to jointly assemble the leakage collection device of the water pump.
