an improvement of suspended semi submersible vertical turbine pump

An improvement of suspended semi submersible vertical turbine pump, comprising a pump casing and a pump frame. The pump casing has an inlet end and an outlet, and a pump shaft is installed inside the pump casing. The pump is characterized in that: the inlet end is sequentially connected in series with multi-stage straight pipes and flow deflectors, and the front end of the pump shaft is sequentially connected in series with multi-stage transition shafts. Couplings are used to connect the pump shaft to the transition shaft and between adjacent transition shafts. Bearing supports are installed between each transition shaft and the straight pipe for support; The deflectors are bowl shaped, and impeller seats are installed on the transition shafts inside each deflector. The impeller seats are equipped with blades, which are located at the front end of adjacent deflectors; The top guide vane is equipped with a water inlet horn at the front end. This technical method can achieve a maximum flow rate of 5900m3/h and a head of up to 365m, further improving the sealing performance and ensuring stable long-term operation of the pump.
