Abstract
A motionless pumping design that reduces operation and maintenance costs, and enhances reliability in three aspects of pneumatics system configuration. A motionless and corrosion-resistant pump which uses the continuous generation of pressure variation push/pull force by relying on the venturi effect induced by a pair of gas ejectors together with an argon pneumatic sub-system.
Claims5
A motionless and corrosion-resistant pumping system that leverages the pressure variation of a push/pull force comprising:
- a plurality of gas ejectors located on a pulsation tube and a salt storage vessel wherein a pressure variation unbalance arises between the pulsation causing molten salt to be either pumped into the pulsation tube by the removal of gas or driven back to the salt vessel by the addition of gas;
- a first and second valve operable between an open and closed position;
- when said first valve is opened, and said second valve is closed, intake gas flow prompts the secondary flow out of the pulsation tube leading to the suction of molten salt from the salt vessel to the pulsation tube due to pressure decreasing;
- when said first valve is closed, and said second valve is open, intake gas flow prompts the secondary flow out of the pulsation tube leading to the molten salt suction from the salt vessel to the pulsation tube due to pressure owing to pressure increasing.
