Example Embodiment
[0020] Example 1:
[0021] A liquid metal cadmium transfer pump, such as figure 1 As shown, it includes a pump casing 7, a drive shaft, and blades. The pump casing 7 is an upright cylinder. The upper section of the cylinder is covered with an insulating layer 5. The insulating layer 5 covers the part of the cylinder exposed to the air. The transmission shaft is a screw shaft 3 installed in the cylinder, the screw shaft 3 is driven by a pulley 1 arranged at its tail end, and the blades are screw blades 6 surrounding the screw shaft. The screw shaft 3 is fixed by a transmission bearing fixed above the cylinder. Supported, the transmission shaft is supported by a transmission bearing seat 2 coaxially connected with the cylinder. The transmission bearing seat 2 and the cylinder are sealed by a sealed impeller 4, and the sealed impeller 4 is a disk fixed with three blades whose angles are opposite to those of the spiral blades.
