PURPOSE: A turbo compressor or rotational structure of an impeller of a turbo blower are provided to supply a diaphragm coupler, capable of forming diaphragm coupling as simple structure and to easily install bearing which supports load of axial direction. CONSTITUTION: A turbo compressor or rotational structure of an impeller of a turbo blower comprise a motor unit(100) and a compression unit(200). The motor unit and the compression unit are independently provided. A rotor of the motor and a first impeller(281) are connected through a diaphragm coupler(44). The first impeller is connected through a second impeller(282) and a clamping bolt(208). A runner shaft(280) is installed between the first impeller and the second impeller. In the rotor of the motor, a cavity is formed. The cavity is inserted in the inner part from the end part of the diaphragm coupler and the side of the diaphragm coupler is opened. The first impeller includes a connection extension unit which is extended to the diaphragm coupler. The connection extension unit includes the cavity which is formed in the inner side while front side is opened. The diaphragm coupler includes a connection shaft, diaphragm disc which is individually formed in both sides of the connection shaft. In the diaphragm disc, a circular valve unit is formed in center and a thickness plate unit which is thicker than thickness of plate of the valve unit is formed around the outer circumference of the thickness plate unit. |
