The connection structure between the shafts of a vertical suspended semi submersible vertical turbine pump

The connection structure between the shafts of a vertical suspended semi submersible vertical turbine pump mainly consists of a first shaft, a second shaft, and a coupling. The outer peripheral surface of the first connecting section has a first bonding hole. The coupling has a first coupling hole, which is connected to the first coupling hole and the first coupling hole through a first connecting piece to prevent the first shaft from rotating inside the first connecting hole. The outer surface of the second connecting section has a second bonding hole. The coupling has a second coupling hole, which is connected to the second coupling hole through a second connecting piece to prevent the second shaft from rotating within the second connecting hole. The advantage of this technical method is that it prevents the transmission of shaft reversal, simplifies assembly and disassembly, reduces some energy loss caused by reversal to a certain extent, and extends the service life of impellers and pumps.

Technical requirements: 1. A connection structure between shafts for a vertical suspended semi submersible vertical turbine pump, characterized by comprising a first shaft having a first connection section, the outer peripheral surface of the first connection section having a first external thread, and the outer peripheral surface of the first connection section also having a first coupling hole; The second shaft has a second connecting section, and the outer surface of the second connecting section has a second external thread. The outer surface of the second connecting section also has a second coupling hole; And, a coupling having a first end and a second end, wherein the coupling has an observation hole, a first connection hole, and a second connection hole, wherein the observation hole extends radially inward from the outer peripheral surface of the coupling, the first connection hole extends axially from the first end face of the coupling to the observation hole, and the inner peripheral surface of the first connection hole has a first internal thread corresponding to the first external thread. By cooperating with the first external thread, the first shaft is fixedly coupled with the coupling, and the second connection hole is fixedly coupled with the second end face of the coupling. extending along the axial direction of the coupling to the observation hole, The inner peripheral surface of the second connecting hole has a second internal thread corresponding to the second external thread, and the second shaft is fixedly combined with the coupling by cooperating with the second internal thread and the second external thread; The coupling also has a first coupling hole, which extends radially from the outer end face of the coupling to the inner peripheral surface of the first connecting hole, and corresponds to the first coupling hole. The first coupling hole is connected to the first coupling hole by a first connecting piece to prevent the first shaft from rotating inside the first connecting hole; The coupling also has a second coupling hole, which extends radially from the outer end face of the coupling to the inner peripheral surface of the second connecting hole, and corresponds to the second coupling hole. The second coupling hole is connected to the second coupling hole by a second connecting piece to prevent the second shaft from rotating inside the second connecting hole.
