ABSTRACT:
A method for reliably operating turbocompressors in which flow and forwarding pressure defining the operating point of a compressor are continuously measured. At least one blow-off valve or blow-around valve is opened by a blow-off regulating system to prevent surging once the operating point of the compressor has attained a blow-off curve that parallels a surge limit, but before the operating point can attain the surge limit so that the flow will attain a minimum level depending on the forwarding pressure. The speed at which the operating point moves relative to the blow-off curve or surge limit is determined continuously to obtain the opening of either one of the valves ahead of time. The blow-off valve or blow-around valve is opened at maximum speed by a procedure that supercedes a normal blow-off regulation system when the operating point has arrived at or beyond a rapid valve-opening curve representing a speed-dependent minimum distance of the operating point from the blow-off curve. The motion in opening the valve is discontinued and regulation of the valve is resumed beginning with its latest state by the normal blow-off regulation system when the operating point has traveled back beyond the rapid valve-opening curve.
