Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0022] like figure 1 and figure 2 As shown, two examples of a liquid expander rotor, such as figure 1 In the example of the rotor shown, the main shaft 1 at the gearbox end is connected with the diaphragm coupling 7 through a triangular shaft and fixed with a fastening nut 8 . like figure 2 In the rotor example shown, the main shaft can also be connected to the diaphragm coupling 7 via a key 9 . The oil throwing ring 3 and the oil throwing ring baffle 4 are fixed by the hexagon socket head screw 5 .
[0023] The impeller 2 adopts a radial flow centripetal impeller, which can be a closed structure or a semi-open structure ( image 3 ), or fully open structure ( Figure 4 ). There is a triangular hole at the center line of the impeller, which is connected with the triangular journal of the main shaft. The impeller radially enters the l...
