  • Liquid metal mechanical pump
    Patent number: 4511315
    Abstract: A liquid metal mechanical pump, having therein a liquid metal free surface and a cover gas space over the liquid metal free surface, is equipped with an emergency gas line shut-off system. This system can shut off a cover gas line by the solidification of liquid metal to thereby prevent the leakage of cover gas and the rise of the liquid metal level in the pump at the time of the failure of the cover gas line. The mechanical pump may further be equipped with an emergency syphon system which can discharge liquid metal when the liquid metal level in the pump exceeds a predetermined level.
