摘要： A multistage centrifugal compressor has a shaft rotatable on an axis and a plurality of centrifugal impellers fixed on the shaft and having outlets at outer peripheries thereof. Conduits connect the impellers to from a path for fluid undergoing multi-stage compression by the impellers from a suction side to a delivery side. The conduits including a plurality of diffusers arranged radially outwardly from the impellers, each impeller and associated diffuser constituting a stage. At least two of the diffusers are vaned diffusers provided with vanes having leading edges at their inlet ends. To provide high efficiency combined with low risk of rotating stalls, among the vaned diffusers, the ratio of diffuser vane leading edge radius to impeller outlet radius increases along the fluid path from the delivery of the compressor to the suction side.

摘要： A multi-stage compressor having at least two compressor stages comprises an inter-cooler provided between the stages for cooling a gas being discharged from a compressor in the preceding stage. The compressor stages are driven by a common electric motor, of which a rotating shaft is supported by magnetic bearings. A part of the gas cooled by the inter-cooler and a part of the work gas discharged from a bleed valve provided down-stream of a rear stage of the compressor are selectively introduced into the electric motor or the magnetic bearings. Thus, at the time of load operation the gas discharged from the inter-cooler is introduced into the motor or the magnetic bearings to cool them, and at the time of non-load operation the gas discharged from the bleed valve is introduced into the motor or the magnetic bearings to cool them. It is possible to ensure a flow rate of gas required for cooling the motor during non-load operation with economy during load operation.

摘要： In a rotating machine with employment of a sensor-less DC brushless motor, a terminal voltage of a motor is corrected in a phase corrector by using a motor phase current signal. At this time, the terminal voltage is processed in an integrator and a comparator so as to be converted into an ON/OFF signal having a duty ratio of 1:1. Then, a rotation signal is produced based on an induced voltage which is generated by rotating a permanent magnet rotor, so that a rotation sensor is no longer required. On the other hand, an output derived from the phase corrector is entered as a 1-pulse/1-rotation output signal into a PLL circuit. The PLL circuit contains a phase comparator, a low-pass filter, an oscillator, and a counter. The PLL circuit frequency-divides the 1-pulse/1-rotation output signal. The sine wave data are stored into a ROM with respect to each of the frequency-divided signal positions. The unbalance vibrations of the magnetic bearing are controlled every frequency-divided signal.
