Vertical suspended semi submersible vertical turbine pump impeller connection structure

The vertical suspended semi submersible vertical turbine pump impeller connection structure comprises an impeller (1) and a main shaft (5), wherein the impeller (1) and the main shaft (5) are connected by a conical structure (6). This technical method has a simple structure and is easy to use. It is widely used in vertical suspended semi submersible vertical turbine pumps (VS1 structure in accordance with API610 standard), vertical volute pumps (VS2 structure in accordance with API610 standard), vertical diagonal flow pumps (VS3 structure in accordance with API610 standard), and horizontal single-stage single suction cantilever pumps (OH1 and OH2 structures in accordance with API610 standard). It has strong practical and promotional value.

Technical requirements: 1. An impeller connection structure comprising an impeller (1) and a main shaft (5), characterized in that the impeller (1) and the main shaft (5) are connected by a conical structure (6).
