Abstract: A sensor device for high speed rotating machine includes a rotating body and a sensor assembly. The rotating body includes a magnetic permeable ring and at least one positioning structure. The magnetic permeable ring includes a radial displacement sensing area and a rotational speed sensing area, and the positioning feature is arranged in the rotational speed sensing area. The sensor assembly includes four radial displacement sensors and two rotational speed sensors. The radial displacement sensor is a double-probe type sensor, and the speed sensor is a double-probe or four-probe type sensor. Through different types of the rotational speed sensors and the radial displacement sensors, the rotation speed and turning direction of the rotating body can be calculated.

Abstract: A magnetic bearing centrifugal compressor includes a magnetic bearing spindle having a thrust disk, front and rear axial bearings, an impeller and at least one labyrinth seal. The front and the rear axial bearings are disposed individually to opposing sides of the thrust disk. First and second clearances exist axially between the rear and front axial bearings, respectively, and the thrust disk. The impeller connects a front end of the magnetic bearing spindle. The labyrinth seal pairs the magnetic bearing spindle into an oblique arrangement with respect to the axial direction, and each the labyrinth seal is spaced from the magnetic bearing spindle or the impeller by a labyrinth-seal clearance. By controlling the thrust disk axially, a clearance ratio of the first clearance to the second clearance can be varied to adjust the labyrinth-seal clearance. In addition, a magnetic bearing centrifugal compressor controlling method is also provided.

Abstract: A centrifugal compressor includes a volute base block, a volute cover plate, an impeller, a diffuser-adjusting assembly, a radial constraint assembly, an axial constraint assembly and a driving assembly. A diffuser and a connected volute are formed between the cover plate and the base block. The impeller discharges gas to the centrifugal compressor through the diffuser and the volute. The diffuser adjustment assembly includes a driving ring, a driving rod, a pin and a diffuser ring. The radial constraint assembly is disposed on an inner circumference surface of the driving ring. The axial constraint assembly on an outer circumference surface of the driving ring is located between the top and bottom portions. The drive assembly is to rotate the driving ring. When the driving ring rotates, the pin slides along the pin track, and the driving rod displaces the diffuser ring to adjust a flow-path width of the diffuser.

Abstract: An adjusting mechanism, adaptive to a main body of a centrifugal compressor, comprises a diffuser channel width adjusting assembly and a gas bypass assembly. The diffuser channel width adjusting assembly comprises a width adjusting annular plate and a first valve stem. The width adjusting annular plate is movably disposed in a diffuser channel of the main body. The first valve stem is connected to the width adjusting annular plate, and configured for driving the width adjusting annular plate to move to adjust the width of the diffuser channel. The gas bypass assembly comprises a gas bypass valve and a second valve stem. The gas bypass valve is movably disposed in a gas bypass passage of the main body. The second valve stem is connected to the gas bypass valve, and configured for driving the gas bypass valve to move to adjust the opening of the gas bypass port.
