Device for determining the angular position of a pivotable compressor guide vane

摘要

A device for determining the angular position of a compressor guide vane pivotable about the longitudinal axis thereof disposed in a compressor, associated with a synchronously rotating, flat measuring surface is provided. In order to allow particularly reliable, simple, and nearly error-free detection of the angular positions by means of a robust device, the angular position of the compressor guide vane rotatable about the longitudinal axis thereof is semi-automatically determined by means of the device. To this end, the device includes at least one mounting unit for temporarily fastening the device in alignment on the compressor, and a measuring unit including an angle measuring device having a rotary plate rotatable about the rotary axis, on which rotary plate a vertically protruding measuring arm extending parallel to the rotary axis is provided for making planar contact, via the free end thereof, with the measuring surface.

1. A device for determining the angle position of a compressor guide blade arranged in a compressor and is pivotable about its longitudinal axis and includes a measurement surface which pivots synchronously with the compressor guide blade, the device comprising:
a holding device for temporarily fixing the device to a housing of a compressor from the outside, and a measurement unit arranged on the holding device and comprising an angle measurement device with a rotary plate which is rotatable about an axis of rotation, on which rotary plate is arranged a vertically projecting measurement arm, wherein the measurement arm extends parallel to the axis of rotation and is provided so as to abut areally with its free end against the measurement surface.
