    摘要： A fluid evacuation and expulsion system, having a tank having a tank port, a top, a bottom, and an internal volume defined between the top and bottom, also having a pump having a pump inlet and pump outlet, and having a valve assembly having an actuation lever. A conduit is connected to the tank bottom for allowing fluids to enter and leave the tank. The valve assembly is connected to the pump inlet and pump outlet, as well as the tank port and an environment port. The actuation lever of the valve assembly manipulates four ganged valves which allow the system select between an evacuation mode wherein air is pumped from the tank through the tank port to draw fluids into the tank through the conduit, and an expulsion mode wherein air is pumped into the tank to expel fluids from the tank through the conduit.

    摘要： A tubular pump comprises a "tube-within-a-tube" having a lower end adapted to be submerged in a liquid that is under a pressure p.sub.1, for example a pressure of one atmosphere. The inner and outer tubes are in communication with each other adjacent to the submerged lower end. A pneumatic system alternately applies a pressure p.sub.2 lower than the pressure p.sub.1 to both the inner and outer tubes and a pressure p.sub.3 higher than the pressure p.sub.1 to the inner tube. A check valve mounted in the lower end of the outer tube is open when exposed to the pressure p.sub.2 to enable the liquid to flow upward into both tubes to a height h.sub.1 supported by the pressure p.sub.1 and is closed when exposed to the pressure p.sub.3 to prevent the liquid from flowing backward through the check valve. The liquid therefore flows from the inner tube upward through the outer tube in response to the pressure p.sub.3. A sump line is connected to the outer tube at a height h.sub.2 greater than the height h.sub.1. The space between the inner and outer tubes is configured so that the liquid flows upward through the space in response to the pressure p.sub.3 as an intact mass. The pump is ideally adapted, for example, to pumping out primary-side water from the lower head connected to the lower ends of steam generator tubes of a single-pass steam generator of a large power station.

    摘要翻译： 管状泵包括“管内管”，其具有适于浸没在处于压力p1的液体中的下端，例如一个大气压。 内管和外管彼此相邻，与浸没的下端相邻。 气动系统交替地向内管和外管施加低于压力p1的压力p2和比内管高的压力p1的压力p3。 安装在外管下端的止回阀在暴露于压力p2时是打开的，以使液体能够向上流入两个管，达到由压力p1支撑的高度h1，并在暴露于压力p3时关闭 液体通过止回阀向后流动。 因此液体响应于压力p3从内管向上流过外管。 集水管线以高于高度h1的高度h2连接到外管。 内管和外管之间的空间被配置成使得液体响应于作为完整质量的压力p3向上流过空间。 该泵理想地适用于例如从连接到大型电站的单通蒸汽发生器的蒸汽发生器管的下端的下部头部抽出一次侧水。

    摘要： A compressed air-actuated pump includes a venturi nozzle to create a vacuum condition within a fluid-tight pump body to pump in a liquid or slurry. When a given level of liquid is pumped in, a control circuit closes a flexible sleeve of a pneumatically actuated pinch valve positioned in an exhaust passageway of the venturi nozzle. Upon closing of the pinch valve, the exhaust stream from the venturi nozzle is diverted into the pump body to create a pressurized condition therein whereby the liquid or slurry previously accumulated therein is pumped out. The pump also includes a pair of variable flow control valves for independently adjusting the flow rates of compressed air through the venturi nozzle in the vacuum, pump-in and in the pressurized, pump-out cycles. Solid state opto-electronic liquid level sensors or appropriate pneumatic, electric or electro-pneumatic timing devices are employed to signal the opening and closing of the pinch valve. The flexible sleeve of the pinch valve, as well as all other parts in the pump are constructed of chemically-resistant materials to permit the pumping of erosive, corrosive and abrasive liquids and slurries.

    摘要： An air actuated vacuum pump has a pair of chambers positioned about a rotatable air passageway structure in which a partial vacuum is established by a Venturi jet with the air passageway structure arranged to communicate alternately with said chambers. A base including inlet and outlet passageways and a valve forming extensions of the air passageway structure supports the chambers and the valve establishes alternate communication between the chambers and said inlet and outlet passageways respectively. Means is provided for rotating said air passageway structure and openings in the upper portions of said chambers alternately communicate with said air passageway structure so that partial vacuums may be created therein so as to effect a pumping action.

    摘要： An automatic pipetting apparatus comprises a hand-holdable pipet-operating apparatus which includes means for releasably coupling a plurality of interchangeable pipets to a low-deadspace valving structure. The valving structure operates the pipets by selectively sealing or applying suction or pressure to a pipet. A pipet driving subassembly including pressure and suction pumps is coupled to the pipetting apparatus by flexible tubes, permitting continuous application of suction and pressure to the pipet-operating apparatus as well as free movement of the pipet-operating apparatus with respect to the pipet driving subassembly.
