摘要： Apparatus and method for creating a compact inlet guide vane system and reducing the force required to operate the inlet guide vane system. Components of the inlet guide vane system, including but not limited to an actuation rod, actuation ring, crank rods, cranks and the associated connectors and bushings are assembled in the same plane. In this regard, when a force is applied to the actuator rod and transferred through the inlet guide vane system components, the force acts in a single plane. Further, the plane is centered over the rotational axial center of the actuation ring.

摘要： An actuated rotary valves for reciprocating compressors used in oil and gas industry, the valve including a stator with a stator opening, a rotor with a rotor opening, and an actuation mechanism. The actuation mechanism is configured to receive a rotation motion and to actuate the rotor to perform first an axial translation moving away from the stator and then a rotation. The actuation mechanism includes an outer shaft configured to receive the rotation motion, and an inner shaft inside the outer shaft and configured to rotate the rotor. The outer shaft is configured to rotate a predetermined angular displacement while pushing the rotor away from the stator before engaging the inner shaft to rotate together with the rotor.

摘要： A combined thermodynamic system is described, for the production of mechanical power. The system comprises a gas turbine (1) and a turbomachinery (2) driven by the gas turbine (1). The system further comprises a thermodynamic organic Rankine cycle (5) with a turboexpander (13). A heat transfer arrangement (9a, 9, 11) transfers heat from exhaust combustion gases of the gas turbine to the thermodynamic organic Rankine cycle, wherein heat is converted into mechanical power used for driving a driven a turbomachine.

摘要： System and method for determining a susceptibility of a sample (26) of material, which includes a welded area (20), to reheat cracking. The method includes measuring a length of the sample (26), applying a first stress to the sample (26) to achieve a predetermined elongation of the sample (26), exposing the elongated sample (26) to a predefined heat treatment, applying a second stress to the sample (26) until the sample breaks at least into two different pieces (30, 40), and determining the susceptibility of the broken sample (26) to reheat cracking.

摘要： Actuator devices 300 useable to change orientation of one or more vanes, and related methods separating a first fluid at one end of an actuator 310 rod and a second fluid at an opposite end of the actuator rod are provided. An actuator device includes the actuator rod and an actuator device body 320 configured to allow the actuator rod to move along the axis inside the actuator device body, and having an inlet flange 322 configured to allow a third fluid to enter a space between the actuator device body 320 and the actuator rod 310, and an outlet flange 324 configured to allow the third fluid to exit the actuator device body. Besides providing a fluid seal between the first fluid and the second fluid, the third fluid may also heat the actuator rod thereby preventing ice formation.
