摘要： A vertically mountable shaft and bearing assembly includes a thermally insulated housing which protects the shaft, bearing(s), seal(s), and bearing lubricant from overheating due to a surrounding process fluid at a temperature exceeding 65° C. The thermal insulation, which in some embodiments includes vacuum, air, or an insulating material, enables a rolling element bearing to be located near the shaft's distal end, thereby reducing shaft and bearing size requirements. Lubricant is circulated past the bearing(s) by a circulation and cooling system having a capacity typical of systems used with process fluids at much lower temperatures. Additional roller and/or journal bearings can be included. The lubricant circulation system can be actuated by the shaft or driven separately. Lubricant within the shaft housing can be pressurized, for example by pressurizing gas or by filling the lubricant above the surrounding process fluid level. The shaft can operate a process fluid pump impeller.
摘要翻译：垂直安装的轴和轴承组件包括一个隔热的外壳，其保护轴，轴承，密封件和轴承润滑剂免受过温度超过65℃的周围过程流体的过热。隔热，其在一些实施例中包括真空，空气或绝缘材料，使得滚动元件轴承能够位于轴的远端附近，从而减少轴和轴承尺寸要求。润滑剂通过循环和冷却系统循环通过轴承，该循环和冷却系统具有在较低温度下与过程流体一起使用的典型系统的能力。可以包括额外的滚子和/或轴颈轴承。润滑剂循环系统可以由轴致动或单独驱动。轴壳体内的润滑剂可以被加压，例如通过对气体进行加压或者通过将润滑剂填充到周围的过程流体水平以上。轴可以操作过程流体泵叶轮。

摘要： An improved, piston-based, pressure-transforming barrier fluid support apparatus is disclosed that can support both the pressurized and unpressurized barrier fluid requirements of a shaft-driven machine from a single unit. The disclosed apparatus includes both a pressurized section that stores, cools, cleans, and pressure regulates pressurized barrier fluid, and an unpressurized section that stores, cools, and cleans unpressurized barrier fluid. The disclosed apparatus causes debris in the pressurized barrier fluid to gravitationally migrate away from the piston, so as to prevent piston fouling. If the piston rod becomes detached, it is expelled downward for enhanced safety. Removable covers and/or a removable cylinder can provide enhanced access for cleaning and maintenance. Embodiments include a common cover that is shared by the pressurized and unpressurized sections and serves as a common manifold for cost-efficient fluid connections thereto.
摘要翻译：公开了一种改进的基于活塞的压力转换阻挡流体支撑装置，其能够从单个单元支撑轴驱动机器的加压和非加压屏障流体要求。所公开的设备包括存储，冷却，清洁和压力调节加压屏障流体的加压部分和存储，冷却和清洁未加压的阻隔流体的非加压部分。所公开的装置使加压屏障流体中的碎屑重力地离开活塞迁移，以防止活塞结垢。如果活塞杆脱落，则将其向下排出以提高安全性。可拆卸盖和/或可拆卸缸可以提供更好的清洁和维护接入。实施例包括由加压和非加压部分共享的共同盖，并且用作与其成本有效的流体连接的共同歧管。

摘要： A canned motor has an L3/D4 ratio of less than 50, with one bearing on one end of the rotor assembly configured to resist longitudinal displacement of the rotor as by an axial shaft load, and another bearing on the other end of the rotor assembly configured to allow limited longitudinal displacement of the rotor assembly within the bearing as from thermal expansion, lengthwise adjustment or pressure from an axial shaft load. The rotor assembly may include a center shaft coaxially extended through a hollow shaft, with rotor windings mounted on the hollow shaft, with the first bearing positioned on one end of the hollow shaft and the second bearing mounted on the second hollow shaft end. A cap and nut assembly on the second hollow shaft end, into which the rotor shaft end is threaded, provides for adjusting the effective rotor shaft length protruding from the motor, and for replacement of the rotor shaft within the hollow shaft without removing the rotor assembly from motor.

摘要： A rotor and shaft assembly for turbomachinery has a polygon shaped drive collar interposed between corresponding polygonal mating surfaces of a drive shaft and a rotor hub. The mating surfaces of the polygon collar, the drive shaft and the rotor hub may be sized both axially and radially for required torque transmission without the need for hub inserts or oversized shafts. The polygon drive collar is manufacturable using standard machine tools such as lathes and end mills that remove metal in a tool path following not more than two axes of simultaneous movement. A shaft end assembly secures the rotor and drive collar to the shaft.

摘要： A device for reducing solids and increasing pressure in a fluid handling system has comminution and inducer sections in a housing upstream of a pump impeller. A rotor has a hub with a small inlet diameter and a larger outlet diameter and a helical rotor blade with its blade pitch angle progressively increasing from inlet to outlet as a polynomial function. The comminutor section has a larger diameter than the inducer section and comminutor vanes extending inward forming a vane edge effective diameter equal to the inducer section diameter. The rotor blade turning within the closing fitting cage of vane edges provides a crushing and shearing action to solids in the fluid flow. Cutouts on the blade edge provide additional crushing and shearing action against the vanes. The fluid passageway sectional area at the outlet is bigger than the throat of the downstream main impeller.
