Abstract
When controlling a turbocompressor to prevent pumping there is generated a control signal which controls a blowoff or recycle valve attached to the compressor outlet by continuously monitoring the working point or operating condition coordinates and comparing the coordinates with a blowoff line defined by operating conditions producing a pumping. Upon the occurrence of a pumping surge, a signal is generated which can control for instance the quick opening of the blowoff valve. In addition, according to the invention the signal generated upon the occurrence of a pumping surge is also utilized to initiate a new fixation of the blowoff line or the pumping limit line.
