摘要： A cryogenic oil-free direct drive turbogenerator for gas liquefaction plant applications is described. The pressure energy from cryogenic gas is expanded through a turbine and the power generated is converted into electricity through a directly driven generator and a power electronics arrangement. The machinery can withstand very cold temperature operation (e.g.,

摘要： A casing half shell for a turbine system, a steam turbine system and related method are provided. The casing half shell includes a body having an open interior for enclosing parts of the turbine system; a first inlet in the body for delivering a first working fluid flow into the open interior in a first direction; and a second inlet in the body for delivering a second working fluid flow into the open interior in a second direction that is opposed to the first direction. A working fluid dam extends radially and axially in the body between the first inlet and the second inlet, the working fluid dam includes a stress-mitigating slot extending radially therein. A fill member may be mounted in the stress-mitigating slot to provide full functioning of the working fluid dam.

摘要： A pressure vessel for a turbine is disclosed. A cylindrical shape of the pressure vessel is divided into two parts in a radial direction of the pressure vessel and the pressure vessel is connected in the cylindrical shape via flanges protruding outward in the radial direction of the pressure vessel at both divided ends of the pressure vessel. Increased thickness portions are defined in a portion excluding the divided ends and circular arc center portions farthest from the divided ends. The portion is between the divided ends and the circular arc center portions and the increased thickness portions increase radial thickness of the portion.

摘要： The method for retrofitting a double flow steam turbine includes opening an outer casing of the steam turbine, removing the blade carriers and the stator blades, removing the inner casing with inlet belt, removing the double flow rotor and the rotor blades. Thus, the method includes the further steps of providing a new single flow rotor and new rotor blades different from the rotor blades connected to the double flow rotor, providing balancers connected to the single flow rotor, to balance the axial thrust, providing new stator blade carriers and new stator blades different from the stator blades associated to the double flow rotor, providing a new inner casing with inlet belt, providing a passage between the inner casing and the outer casing, closing the outer casing.

摘要： A multiple stage variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the multiple stage blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.

摘要： A centrifugal pump has alternating impellers and diffusers. One or more vent holes extend through one or more vanes of one or more diffusers. In an upthrust condition, high pressure production fluid from an upper impeller is able to pass through the one or more vent holes, and thereby exert force on the preceding impeller. The force exerted on the preceding impeller offsets the upthrust force acting against the preceding impeller.

摘要： A rotating shaft is supported by journal bearings that can support without contacting the rotating shaft itself. Then, one end of both shaft end portions of the rotating shaft has a main impeller installed and the other end is provided with a sub impeller. By utilizing a force being generated by rotation of the main impeller, liquid being pumped (fluid being pumped) is sucked in through a suction port and discharged through a discharge port. On the other hand, by utilizing a force being generated by rotation of the sub impeller, fluid is transported to the journal bearings, thereby having the journal bearings support the rotating shaft.

摘要： An electronic assembly (1) includes a top cover (21), a bottom cover (22) and a thermal module (10). The thermal module includes a centrifugal blower (14) and a fin assembly (12). The blower includes a top lid (142) defining a first air inlet (146) therein, a bottom plate (147) defining a second air inlet (150) therein, and a sidewall (148). An air outlet (149) is defined in the blower in front of the sidewall. A first distance (H1) formed between the top cover and the top lid is greater than a second distance (H2) formed between the bottom cover and the bottom plate. A left edge (154) of the second air inlet adjacent to the air outlet offsets a distance from a corresponding left edge (155) of the first air inlet inwardly toward a rotation axis (A) of an impeller (143) of the blower.
