Suspended semi submersible vertical turbine pump and its assembly method

A suspended semi submersible vertical turbine pump and its assembly method, the suspended semi submersible vertical turbine pump comprising multiple transmission shafts, couplings, and snap rings, adjacent two transmission shafts connected by the couplings, the couplings comprising a first half coupling and a second half coupling, the first half coupling and the second half coupling being connected along the axial direction of the transmission shaft; The snap ring is clamped inside the coupling, and the snap ring comprises a first half snap ring and a second half snap ring. The first half snap ring and the second half snap ring are docked radially along the transmission shaft; Each of the transmission shafts includes a stepped portion located at its end, and the stepped portions of adjacent transmission shafts are arranged opposite to each other. The snap ring is engaged with the stepped portion. Compared with related technologies, the transmission shaft connection of the suspended semi submersible vertical turbine pump in this technology is convenient, easy to disassemble, and easy to maintain. This technology also provides an assembly method for a suspended semi submersible vertical turbine pump.
