摘要： Devices and systems for exchanging properties between at least two fluid streams and related methods may include a valve device comprising a valve actuator configured to move at variable rates in order to selectively fill and empty at least one tank. Devices for exchanging properties between at least two fluid streams may include a valve device comprising staggered and overlapping openings positioned along a path of a valve actuator. The staggered and overlapping openings may be configured to selectively and gradually place an inlet in communication with at least one tank.

US09689402B2 Centrifugal pump impellor with novel balancing holes that improve pump efficiency 有权

摘要： A centrifugal pump impellor includes balancing holes that reduce axial thrust while minimizing the loss of pump efficiency. In one general aspect, the balancing holes penetrate the rear shroud between the blades, and are angled in both axial and rotational directions so as to direct the leakage fluid approximately parallel to the primary process fluid, so that it causes minimal interference with the primary fluid flow. In a second general aspect, the balancing holes extend from the rear cavity within the impellor blades and through the leading edges of the blades, thereby entering the primary flow in locations where the process fluid is almost static relative to the blades. This minimizes the impact on the flow of the process fluid past the blades, and thereby minimizes the loss of pump efficiency caused by the balance holes. In embodiments, each blade leading edge includes a plurality of balancing hole outlets.

摘要翻译：离心泵叶轮包括平衡孔，减少轴向推力，同时最大限度地减少泵效率的损失。在一个一般方面，平衡孔穿过叶片之间的后护罩，并且在轴向和旋转方向上成角度，以便将泄漏流体引导到大致平行于主处理流体，使得其对主流体产生最小的干扰流。在第二个一般方面，平衡孔从叶轮内的后腔延伸并且穿过叶片的前缘，从而在过程流体相对于叶片几乎静止的位置处进入主流。这最小化对过程流体经过叶片的流动的影响，从而最小化由平衡孔引起的泵效率的损失。在实施例中，每个叶片前缘包括多个平衡孔出口。

摘要： Devices and method include relatively moving elements having one or more bearing surfaces defining a gap between the elements into which a fluid is received. At least one of the bearing surfaces comprises a varying topography to provide pressurized volumes of the fluid in order to define a hydraulic bearing to support at least one of the elements during movement.

摘要： Pressure exchange devices and related systems may include a valve device configured to selectively place a fluid at a first higher pressure in communication with another fluid at a lower pressure in order to pressurize the another fluid to a second higher pressure. Methods of exchanging pressure between at least two fluid streams may include a pressure exchanger having two low pressure inlets.
