摘要： A pump system is presented having a pump with a generally cylindrical pump housing that is arranged with a liquid inlet in one end and a liquid outlet in a second end. A tubular membrane is arranged inside the pump housing and a first passage is arranged in the vicinity of the liquid inlet for introducing pressurized fluid between the membrane and the housing. A second passage arranged in the vicinity of said liquid outlet for releasing said pressurized fluid where the membrane is arranged with an elasticity providing a local radial compression and an annular fluid compartment when a pulse of pressurized fluid is entered through the first passage. The annular fluid compartment travels along the housing bringing a volume of liquid with it. An expansion vessel can be operably attached to the liquid outlet for reducing pressure changes in the liquid caused by the action of the pulse of pressurized fluid.

摘要： A pump system for conveying a first fluid using a second fluid. The system includes at least a first pump having at least a first rigid outer casing defining a first interior space and a first flexible tube structure accommodated in the first interior space. The interior of the first flexible tube structure is arranged for receiving one of the first or second fluids. The region of the first interior space surrounding the first flexible tube structure is arranged for receiving the other of the first and second fluids. The first flexible tube structure is movable between laterally expanded and collapsed conditions for varying the volume of the interior of the first flexible tube structure, thereby imparting sequential discharge and intake strokes on the first fluid.

The electrochemical actuator has at least one electrode fluidically coupled to the driving fluid chamber of the first pump housing and at least one electrode fluidically coupled to the driving fluid chamber of the second pump housing. Accordingly, the electrochemical actuator selectively pressurized hydrogen gas within a driving fluid chamber.

A controller may reverse the polarity of a voltage source electrically coupled to the current collectors, wherein a first polarity simultaneously decreases the hydrogen gas pressure in the first hydrogen gas chamber and increases the hydrogen gas pressure in the second hydrogen gas chamber, wherein a second polarity simultaneously increases the hydrogen gas pressure in the first hydrogen gas chamber and decreases the hydrogen gas pressure in the second hydrogen gas chamber.

摘要： A liquid pump is provided and particularly a downhole pump for use in an oil well bore for pumping oil or in a gas well to remove condensate. The downhole pump includes a plurality of pump and transfer modules, each of which includes an elongate housing with end couplings and with two internal passages extending therethrough. The pump module further has a bladder extending between the end couplings around the internal passages with the couplings having passages connecting one of the internal passages to space on one side of the bladder. When fluid, preferably gas, under pressure is supplied to that passage, the bladder forces liquid therein upwardly into the next module. At the same time, fluid under pressure is exhausted through one of the passages from the space on the opposite side of the bladder of the next pump module, aiding it to receive liquid from the pump module therebelow. The transfer modules supply the liquid up from a lower pump module to an upper one and connect the fluid passages to enable the fluid to operate the bladders. The modules have check valves at the lower ends enabling flow of liquid only in the upward direction. However, the check valves have provisions for being opened when fluid under greater than operating pressure is applied thereto to enable liquid in the modules to drain back down through the pump.
摘要翻译：提供液体泵，特别是用于在油井中泵送油或在气井中以去除冷凝物的井下泵。井下泵包括多个泵和传递模块，每个泵和传送模块包括具有末端联轴器的细长壳体以及从其延伸穿过的两个内部通道。泵模块还具有在围绕内部通道的端部联接件之间延伸的囊，联接器具有将内部通道中的一个连接到囊的一侧上的空间的通道。当压力下的流体（优选气体）被供应到该通道时，气囊将液体向上压入下一个模块。同时，压力下的流体通过来自下一个泵模块的气囊相反侧的空间中的一个通道排出，辅助它从下面的泵模块接收液体。转移模块将液体从下部泵模块提供给上部模块，并连接流体通道以使流体能够操作气囊。模块在下端具有止回阀，使液体只能向上流动。然而，止回阀具有在大于工作压力的流体被施加到其上的情况下打开的装置，以使模块中的液体能够通过泵排出。
