Semi submersible suspended vertical turbine pump shaft connection device

A semi submersible suspended vertical turbine pump shaft connecting device, comprising an upper connecting shaft and a lower connecting shaft connected by threads, characterized in that: the outer sides of the upper connecting shaft and the lower connecting shaft are respectively machined with shaft shoulders, and the shaft shoulders are clamped with half clamps; The upper and lower connecting shafts are also respectively equipped with keyways, and keys are installed inside the keyways. This technical method uses threaded connections, where the threads and shaft shoulders jointly bear the axial load and can support some radial forces. The pump shaft transmits torque through a key, and at the same time, the axial positions of the upper and lower connecting shafts are fixed by a split half ring installed at the shaft shoulder, ensuring the concentricity of the shaft and ensuring the safety of the connecting shaft. This type of shaft connection method has a novel structure, is safe and reliable, has a small radial size, is easy to disassemble and assemble, and is simple to process. It is worth widely promoting and applying.
