Abstract (en)
[origin: CN113007055A] The invention relates to a method for operating a variable-speed control pump. In the method, a delivery mechanism (122), which can be adjusted in a displacement per working cycle, is driven by means of a variable-speed drive (121), at least one variable is controlled to a target value (psoll) by specifying a rotational speed target value (nsoll) for the rotational speed of the drive and a target value ([alpha] soll) for determining a characteristic variable of the displacement for each operating cycle, wheren when the target value ([alpha] soll) of the characteristic variable for determining the displacement for each operating cycle is changed, the target rotational speed value (nsoll) is adapted by pre-control.
