    摘要: A multi-stage fluid compression system includes a first centrifugal compressor stage having a first inlet and a first outlet and a second centrifugal compressor stage having a second inlet and a second outlet. The second inlet receives a flow of compressed fluid from the first outlet. A first variable-speed motor is coupled to the first centrifugal compressor stage and is operable to drive the first centrifugal compressor stage at a first speed. A second variable speed motor is coupled to the second centrifugal compressor stage and is operable to drive the second centrifugal compressor stage at a second speed. The first speed and the second speed are each independently variable.

    摘要: A bleed valve assembly for discharging bleed air into a gas turbine engine bypass plenum (116) includes a bleed flow duct (202), a bleed valve (204), and a flow deflector (206). The bleed flow duct (202) is contoured such that it delivers uniformly flowing bleed air to the flow deflector (206) when the bleed valve (204) is in the open position. The flow deflector (206) has a plurality of openings (218-1, 218-2) formed therein. Each opening (218-1, 218-2) fluidly communicates the bleed air flow passage with the bypass plenum (116). A portion of the openings (218) are oriented at a discharge angle such that bleed air is discharged from each opening (218-1, 218-2) in a direction that does not have a vector component in the direction in which air is flowing in the bypass plenum (116), and another portion of the openings (218) are oriented to provide stress relief to the deflector (206).

    摘要: A system for controlling air flow comprises an inlet (50), a first compressor (54), a first pressure sensor (52), a second pressure sensor (56), a first temperature sensor (58), and a first controller (51). The inlet is configured to direct a first stream of air into the system. The first compressor is configured to pull in the first stream of air through the inlet and compress the first stream of air. The first pressure sensor senses a first pressure of the first stream of air prior to compression in the first compressor, the second pressure sensor senses a second pressure of the first stream of air after compression in the first compressor, and the first temperature sensor senses a temperature of the first stream of air after compression in the first compressor. The controller (51) adjusts a speed of the first compressor (54) based upon a comparison between a desired flow rate and a calculated flow rate.

    摘要: A control system is provided to maintain stable operating conditions for centrifugal compressors (108, 110) operating in parallel when one of the centrifugal compressors (108, 110) enters into an unstable operating condition. The control system determines an unstable operating condition in response to signals (172, 174, 176, 178) indicating the motor current or power consumption of each compressor (108, 110) and the position of the pre-rotation vanes (120, 121) of the compressors (108, 110). Once an unstable operating condition is determined, the control system closes the pre-rotation vanes (120, 121) to each compressor (108, 110) until the unstable operating condition has been corrected.

    摘要: A turbocharger (12) for an internal combustion engine (36) has a compressor operable as single stage or multi-stage compressor. A first compressor stage includes a first compressor wheel (16) carried by a shaft (56), an axially extending first inlet (60) and a radially extending first outlet (62). A second compressor stage includes a second compressor wheel (20) carried by the shaft (56) and axially extending second inlet (64) and a radially extending second outlet (66). An interstage duct (68) fluidly connects in series the first outlet (62) of the first compressor with the second inlet (64) of the second compressor. The interstage duct (68) includes a bypass opening (72) includes in communication with an ambient environment. A valve (70) is positioned within the interstage duct (68). The valve (70) is moveable to and between a first position to close the interstage duct (68) while the bypass (72) stays open and a second position to close the bypass opening (72).
