摘要： An integrated centrifugal pump and motor is provided by an impeller disk which contains permanent magnets and functions as the rotor for a brushless DC motor. The rotor is supported by non-contacting radial bearings and is hydrodynamically balanced against any axial thrust so that there is no contact between rotating and stationary elements during operation. Since the impeller disk is also the motor rotor, there is no need for a shaft, in the ordinary sense, which would penetrate the case and, thus, require seals. The resulting pump is compact and can be operated electronically at variable speeds.

摘要： A fluid pump with rotary impeller is disclosed which comprises an electromagnetically driven rotary impeller levitated by localized opposed fluid forces. Levitation by localized opposed fluid forces of an impeller driven by electromagnetic forces eliminates the need for bearings and seals in the driving mechanism. This avoids the heat build-up and leakage associated with other pumping mechanisms, which can be of importance for pumping of physiological fluids such as blood. The levitating fluid forces of the present invention are auto-adjusting, such that any attempted displacement of the impeller will automatically incur a corrective change in levitating fluid forces. However, fluid force sensors and regulators could be incorporated into the present invention if desired. The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized fluid forces are apparent.
摘要翻译：公开了一种具有旋转叶轮的流体泵，其包括通过局部相对的流体力悬浮的电磁驱动旋转叶轮。通过由电磁力驱动的叶轮的局部相对的流体力的悬浮消除了对驱动机构中的轴承和密封的需要。这避免了与其他泵送机构相关的积热和泄漏，这对于泵送诸如血液的生理液体来说是重要的。本发明的悬浮流体力是自动调节的，使得任何尝试的叶轮位移将自动引起浮力流体力的校正变化。然而，如果需要，可将流体力传感器和调节器并入本发明。本发明应用于许多医疗和非医疗应用，其中通过局部流体力的叶轮悬浮的益处是显而易见的。

摘要： A rotary pump includes a rotor having delivery elements which deliver at least a portion of a fluid in an axial direction of the rotor. Two delivery elements or groups of delivery elements are provided on the rotor for delivering the fluid, and deliver the fluid to be delivered in mutually opposing axial directions of the rotor, so that the axial thrust components substantially compensate each other. The fluid flows flowing counter to each other jointly give way in the radial direction of the rotor and can be jointly discharged through the volute casing and utilized.

摘要： Disclosed is an apparatus for separating solids within a water carrier having different specific gravities. The apparatus includes an axial-flow pump with an impeller (13). The apparatus includes a hollow tube (11) sized and positioned to discharge a fluid stream where the solids within the fluid stream have a specific gravity less than one. The hollow tube (11) includes an inward facing opening that makes an oblique angle along its entire circumference with respect to a longitudinal axis of the hollow tube (11). This arrangement is especially useful in municipal and sanitary wastewater treatment applications for keeping lighter-than-water debris such as hair, food fiber, and synthetic fibrous materials from building up against the leading edge of the hollow tube (11) and clogging it.

摘要： A centrifugal blood pump without a mechanical bearing comprises a pump casing (1), an impeller (9) arranged in the pump casing rotatably about the central axis and freely movable axially and radially within a limited clearance. The impeller has permanent magnets or permanently magnetized magnetic regions (N/S) which cooperate with an electromagnetic drive to set the impeller rotating. A circular wall (12) or circularly arranged wall sections are provided within the pump casing, their inner surfaces defining a radial clearance together with the outer circumference of the impeller to form a hydrodynamic radial bearing for the impeller.

摘要： A jet propulsion drive element is disclosed for the increasing of the power yield of jet engines, in particular for watercraft, employing a rotary-driven jet propulsion pipe (11). A thrust propulsion element is disposed at the inner jacket of the jet propulsion pipe (11), covers an outer annular face (A), and is formed as a screw (17). The outer edge of the screw (17) is connected to the inner jacket of the jet propulsion pipe (11). The edge screw (17) is furnished with a through borehole, such that a part of the fluid entering into the jet propulsion pipe (11) is not directly accelerated by the edge screw (17). In addition, drive elements such as a screw propeller (18) can be furnished at the outer jacket of the jet propulsion pipe (11). The invention structure can be employed also for circulating pumps in addition to applications in aircrafts.
