    • A method is for determining the angular positions of multiple compressor guide vanes. The method includes measuring the positions of at least two points on the circumference of the actuating ring, via at least two linear position sensors fixed on the compressor casing, and pointing at the actuating ring vertically at a time when the actuating ring deviates from its original position where the ring center coincides with the casing center; calculating the ring center offset based on the measured positions of the at least two points and the radius of the actuating ring; measuring the angle of one of the multiple guide vanes at the same time when measuring the positions of the at least two points; and calculating the angles of the multiple guide vanes based on the ring center offset and the angle of the guide vane. An actuation apparatus for multiple compressor guide vanes is included.
    • 一种用于确定多个压缩机导叶(10)的角位置的方法,包括:(a)通过至少两个线性位置传感器测量致动环(30)的圆周上的至少两个点(P1,Q1)的位置 (40)上并且当致动环(30)偏离其环中心与套管中心重合的原始位置时垂直指向致动环(30)的装置(70,80); (b)基于所述至少两个点(P1,Q1)的测量位置和所述致动环(30)的半径(r)来计算所述环中心偏移量(a1,b1); (c)当测量所述至少两个点(P1,Q1)的位置时,同时测量所述多个导向叶片中的一个导向叶片的角度(αx); (d)基于环形中心偏移量(a1,b1)和导向叶片的角度(αx)计算多个导向叶片(αi)的角度。 还公开了用于多个压缩机导叶(10)的致动装置。
