Operation vane for compressor and compressor with operation vane

The utility model relates to an operation vane for a compressor and the compressor with the operation vane. The operation vane comprises a vane root and a vane blade. The vane blade comprises a flow inlet edge, a flow outlet edge, and a pressure side and a suction side that are extended between the flow inlet edge and the flow outlet edge. The flow inlet edge, the flow outlet edge, the pressure side and the suction side jointly utilizes Descartes coordinate figure x, y and z to define the contour of the vane blade. The first and second contour coordinate or coordinate figure x and y are connected through continuous arcs to describe smooth contour profile at the radial profile height along the third contour coordinate figure z. The radial contour profile utilizes smooth function connection to describe the contour of the vane blade. In each radial contour profile area, the largest contour thickness is within a range of 42% to 52% of chord length of a chord extending at the pressure side and the suction side and extending from the flow inlet edge to the flow outlet edge.
