摘要： A Tuned Mass Damper (TMD) for damping oscillations of a hanging vertical pump structure includes a removable mass symmetrically configured within the pump structure diameter and supported by a mechanism which provides damped mobility relative to the pump structure so as to absorb and dampen pump vibrations and oscillations. The TMD mass is easily removable before tipping of the pump between horizontal and vertical orientations during maintenance. In some embodiments, the TMD mass comprises fluid pumped by the pump to fully or partially fill a housing, the fluid being gravitationally drained therefrom when the pump is not operating. In other embodiments the TMD mass is supplied by removable solid weights. Damped mobility is provided by springs damped by mechanical or fluid friction, or by obstructed movement of fluid within a partially filled housing. In embodiments, the TMD mass is at least 5% of the total mass of the pump structure.

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：可垂直安装的轴和轴承组件包括一个绝热外壳，该外壳在温度超过65°C时保护轴，轴承，密封件和轴承润滑剂免于由周围的过程流体引起的过热。在一些实施例中包括真空，空气或绝缘材料的热绝缘体使滚动元件轴承能够位于轴的远端附近，由此减小轴和轴承尺寸要求。润滑剂通过循环和冷却系统循环经过轴承，循环和冷却系统具有典型的与处理液一起使用的系统的容量，温度低得多。可以包括额外的滚子和/或轴颈轴承。润滑剂循环系统可以通过轴驱动或单独驱动。例如可以通过加压气体或通过将润滑剂填充到周围的过程流体液面之上来对轴壳体内的润滑剂加压。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 device for reducing solids in a fluid flow and increasing fluid pressure, has comminution and inducer sections in a housing upstream of a main pump impeller, and a rotor with a hub of a larger diameter at the outlet than at the inlet of its rotor blades. The blades are notched on their outside diameter, and blade pitch angle progressively increases from inlet to outlet as a polynomial function. The anvil section of the housing has a larger inner diameter than the inducer section, and the inducer section a larger diameter than the rotor. One or more anvil vanes in the anvil section integral to the housing extend radially inward from the inside wall of the anvil section to the inner diameter ID of the inducer section and function to reduce solids by shearing action.

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 submersible electric motor driven pump has a motor chamber and a pump chamber separated by a seal chamber. Inboard and outboard shaft seals(MS1,MS2) immersed in an oil buffer fluid within the seal chamber restricts the flow of liquid from the seal chamber into the pump and motor chambers. An integral or externally mounted pre-pressurized buffer fluid reservoir (PA) maintains a positive fluid pressure in the seal chamber relative to the external pressure at working depth, and maintains a suitable buffer fluid level within the seal chamber, in order to prevent the ingress of the pumped media through the outboard seal(MS2). A unique impeller design (631) circulates fluid within the seal chamber in the region of the outboard shaft seal (MS2), allowing continuous dry run operation when used in conjunction with an integrally cooled motor design. A cartridge shaft sleeve subassembly, having a bearing (3) configured between the inboard and outboard seals (MS1,MS2), facilitates maintenance.
