Embodiment Construction
[0024] figure 1 A composite structure of two parallel-connected turbocompressors 1.1, 2.1 is shown. Each turbo compressor has a curve P1 or P2 ( figure 2 ) The control device 1.2 or 2.2 for maintaining the distance, the control device 1.2 or 2.2 for maintaining this distance, for example, changes the rotational speed of the corresponding compressor and / or opens the pressure reducing valve 1.3 or 2.3. as passed figure 1 As indicated by the dotted double arrow in , the two control devices 1.2, 2.2 communicate with each other and in particular communicate to each other the distance to be maintained by them relative to the surge limit curve.
[0025] now by means of figure 2 A method for controlling such a composite structure according to an embodiment of the invention is explained in detail.
[0026] exist figure 2 , the combined characteristic curve in the form of the pressure ratio Δp of the two turbocompressors 1.1, 2.1 is shown with respect to the displacement dV / dt. ...
