A connection structure between the guide vane body and the lower lifting water pipe in a semi submersible suspended vertical turbine pump with a extractable core

The connection structure between the guide vane body and the lower lifting water pipe in a core withdrawable suspended semi submersible vertical turbine pump includes a guide vane body, which has a connecting part on the guide vane body, and the outer peripheral surface of the connecting part on the guide vane body has a positioning protrusion; And, the lower lifting water pipe has a lower lifting water pipe upper connection part, which surrounds the upper connection part of the guide vane body. The inner peripheral surface of the upper connection part of the lower lifting water pipe has a positioning groove corresponding to the positioning protrusion, and the inner peripheral surface of the upper connection part of the lower lifting water pipe is in contact with the outer peripheral surface of the upper connection part of the guide vane body, and the positioning protrusion is accommodated in the positioning groove. The advantage of this technical method is that by matching the positioning protrusion with the positioning groove, it is equivalent to installing a key to fix it, balance the radial force, and the torque is borne by the pipeline

Technical requirements: 1. A connection structure for a guide vane body and a lower lifting water pipe in a core withdrawable suspended semi submersible vertical turbine pump, characterized by comprising a guide vane body, which has a connecting part on the guide vane body, and the outer peripheral surface of the connecting part on the guide vane body has a positioning protrusion; And, the lower lifting water pipe has a lower lifting water pipe upper connection part, which surrounds the upper connection part of the guide vane body. The inner peripheral surface of the upper connection part of the lower lifting water pipe has a positioning groove corresponding to the positioning protrusion, and the inner peripheral surface of the upper connection part of the lower lifting water pipe is in contact with the outer peripheral surface of the upper connection part of the guide vane body, and the positioning protrusion is accommodated in the positioning groove.
