    摘要: The present invention pertains to a thrust bearing system including a thrust bearing structure having at least one pair of opposed bearing faces defining a bearing space therebetween, and a sub-system for delivering lubricant to the bearing space. A load sensor is provided in association with the bearing structure for determining the loads on the bearing faces. A thrust compensation sub-system is operably associated with the load sensor. This thrust compensation sub-system is operative, upon sensing by the load sensor of a thrust load on the bearing faces in excess of a predetermined limit, to increase the pressure of lubricant being delivered to the bearing space.

    摘要: A turboexpander-generator system employing a housing with a rotatably mounted shaft oriented vertically with a turboexpander associated with the upper end of the housing and shaft, a generator associated with the housing and shaft below the turboexpander and a lubricant pump located at the lower end of the housing and shaft. The lubricant pump controls an actuator valve which controls the variable inlet nozzles to the turboexpander. Thus, a speed control system is achieved through use of the lubricant pump pressure. A seal gas separator is provided with two ports located in the turboexpander exducer at positions of different pressure. High pressure is used to provide a seal between the bearings and the turboexpander. Low pressure is directed to the area of the sump of the pump to enhance continuous lubricant return. A self-priming mechanism causes a reservoir to be charged during pump operation with return of the lubricant to the sump when the pump is off.

    摘要: A seal-off mechanism for preventing migration of working fluid along a turbine shaft which includes a floating seal ring and a shaft shoulder. The seal ring is spring biased against the shaft shoulder. During turbine operation, a pressurized fluid moves the ring away from the shoulder. The pressurized fluid then flows toward the turbine to contain the working fluid. A chamber collects the pressurized fluid and the working fluid for subsequent separation and reuse.

    摘要: A surge control system for a compressor comprising a bypass passage controlled by a bypass valve to return flow to the compressor inlet for avoiding surge in the compressor. The bypass valve is controlled through a sensing of a compressor speed and flow. The compressor speed and the square root of the flow signal, which is proportional to the actual flow, are presented as a ratio for comparison with an empirically established constant. When the conditions of the compressor system are such that the ratio approaches the constant, the bypass valve is opened and the compressor experiences increased flow therethrough.

    摘要: A system for supplying lubricant under pressure to a rotary mounting system having bearings when the main pressurized lubricant supply system fails. The system includes a bladder or other expansible chamber in association with a lubricant reservoir. The bladder has a source of pressurized gas which is either inherently or through regulation maintained at a pressure below that of the main system and above that of the lubricant discharge from the bearings. The source of pressure for the reserve system may be pressure from a gas seal or from the rotor chamber of a pump or turbine. If regulated, the regulation may be by the main lubricant pressure or the pressure of the lubricant discharge. The system also contemplates accommodation for leaks and over pressures.

    摘要: The invention comprises a rotary fluid handling apparatus having first and second coaxial bodies mounted for relative axial movement therebetween and having respective opposed radially facing annular surfaces. The bodies may be, for example, the stator of a turboexpander or compressor and a relatively rotatable clamping ring for a plurality of adjustable blades. A first seal including a sealing ring is disposed between and seals between the annular surfaces, and the apparatus defines a first pressure zone which communicates with one axial side of the seal. The first body has a first stop engageable with the sealing ring to permit the force exerted on the sealing ring by the pressure of the first zone to be transmitted to the first body. The second body carries a second stop engageable with the sealing ring to permit the force exerted on the sealing ring by the pressure of the first zone to be transmitted to the second body, and also to retain the sealing ring from force-transmitting engagement with the first stop. The second stop is further releasable to permit force-transmitting engagement between the sealing ring and the first stop.

    摘要: Disclosed are a system and method for extracting heat from hot unrefined water for the purpose of using this heat to do useful work, and specifically for extracting such heat while minimizing the undesirable effects caused by formation of scale and other solid build-up of scale-forming impurities in the hot unrefined water. Before contact with a heat exchange surface the hot unrefined water has added thereto an agent capable of increasing the formation of non-scale-forming species of said scale-forming impurities. These agents may be added immediately before passing the hot unrefined water through heat exchange equipment and/or directly into a geothermal well.

    摘要: A method and apparatus for power recovery from thermal input. A turbine is disclosed as employing two rotors for two gas cycles, one using a high boiling point fluid and the other using a low boiling point fluid such as steam and butane, respectively. Separation of the fluids is accomplished through mutual collection and selective withdrawal from accumulator tanks. Seals are also disclosed which employ both air and the higher boiling point fluid as a means for preventing the contamination of bearing lubricants by the low boiling point fluids.

    摘要: The invention pertains to improvements in a fluid handling system in which a working fluid passes through a rotor while undergoing a pressure change. A shaft extends longitudinally from and rotates with the rotor. A first seal surrounds the shaft in axially spaced relation to the rotor, and a lubricant having a minimum boiling point is injected into the first seal adjacent the shaft at a pressure sufficient to cause the lubricant to flow axially toward the rotor. A housing surrounds the rotor and shaft and defines a contact zone between the rotor and the first seal for receiving both lubricant and a contact fluid such as the working fluid or a seal buffer gas used to isolate the working fluid from the lubricant. The contact fluid has a maximum boiling point substantially less than the minimum boiling point of the lubricant. A composite liquid comprising contact fluid and lubricant is collected from the contact zone and the contact fluid separated therefrom by fractional distillation in the presence of an additive fluid having a boiling point greater than the maximum boiling point of the contact fluid but less than the minimum boiling point of the lubricant.
