Abstract (en)
[origin: MX2015016613A] An operating method for a pump includes providing a return line for returning the fluid from a high-pressure side to a low-pressure side, controlling a control valve in the return line with a surge control unit for avoiding an unstable operating state, the control valve controlling the throughflow through the return line, storing a limit curve for a control parameter in the surge control unit, comparing an actual value of the control parameter with the limit curve during the operation of the pump; and when the actual value of the control parameter reaches the limit curve, controlling the control valve in the return line such that the actual value of the control parameter is moved away from the limit curve, an operating parameter of the pump being used as the control parameter.
