Fluid pumping system and a fluid turbine system including the fluid pumping system

摘要

Fluid pumping system and method comprise a pumping chamber with inlet and outlet ports. The pumping chamber is in thermal communication with a thermal system for alternating the gas temperature inside the pumping chamber between heated and cooled states. A first valve controls a first fluid communication between the pumping chamber and the external environment, and a second valve controls a second fluid communication between the pumping chamber and the fluid container. The pumping chamber and the valves cooperate to generate a vacuum and a negative potential pressure of the gas inside the pumping chamber by the effect of the gas temperature alternation when the gas passes from a heated state to a cooled state and by controlling the first and second fluid communications. The generated vacuum and negative potential pressure inside the pumping chamber enable pumping of the fluid from the fluid container inside the pumping chamber.

1. A fluid pumping system comprising:
a pumping chamber containing a gas and having a first outlet port at a location spaced from an operative lower end region of the pumping chamber and adapted to be in a first fluid communication with an external environment and through which the gas can pass, in use, from the pumping chamber to the external environment, the pumping chamber further having a first inlet port adapted to be in a second fluid communication with a fluid container from which a liquid is to be pumped into the pumping chamber, wherein the pumping chamber is further adapted to be in a thermal communication with a thermal system for alternating a gas temperature inside the pumping chamber between a heated state and a cooled state; a first valve adapted to control the first fluid communication between the pumping chamber and the external environment; and a second valve adapted to control the second fluid communication between the pumping chamber and the fluid container; wherein the pumping chamber and the valves are in fluid cooperation for controlling a vacuum generated by a reduction of a pressure of the gas inside the pumping chamber resulting from a mass of heated gas passing from the pumping chamber through the first outlet port and to the external environment and from alternation of the gas temperature when the gas passes from the heated state to the cooled state and from the controlling of the first and second fluid communications, wherein the vacuum generated inside the pumping chamber enables pumping of the liquid from the fluid container to an inside of the pumping chamber, and wherein the external environment is the atmosphere.
