Method for controlling an eccentric screw pump

2:

• The method according to claim 1, wherein an operating pressure of the pump or of the medium to be conveyed, in or at the pump, is used as the operating parameter.

3:

• The method according to claim 1, wherein a parameter difference is used as the operating parameter.

4:

• The method according to claim 1, wherein the stator clamping apparatus (12) is connected to the control apparatus (10) and configured as an automated clamping apparatus for a mechanical adjustment of the clamping, and
• wherein the control apparatus (10) iteratively changes, using the stator clamping apparatus (12), as a function of the average value (Δp), until a maximum value of the average value has been reached, and/or iteratively changes, until a minimum value of the pulsation amplitude (Δppp) has been reached.

5:

• The method according to claim 1, wherein the stator clamping apparatus (12) comprises setting elements and/or setting drives.

6:

• The method according to claim 1, wherein the stator clamping apparatus (12) has a mantle (3) that surrounds the stator (1), at least in certain regions, having multiple mantle segments as clamping segments, which can be clamped against the rotor (2), in a radial direction, so as to change the clamping.

7:

• The method according to claim 6, wherein the stator (1) is configured as a longitudinally divided stator composed of at least two partial shells, which can be clamped against one another so as to change the clamping, using the stator clamping apparatus (12).

8:

• The method according to claim 1, wherein the operating parameter is made available by means of measurements.

9:

• A control apparatus for an eccentric screw pump, comprising means that are suitable for carrying out the method according to claim 1.

10:

• The control apparatus according to claim 9, comprising at least one sensor (11a, b) for measuring the operating parameter.

11:

• The control apparatus according to claim 10, comprising at least one pressure sensor for measuring an operating pressure.

12:

• A computer program comprising commands that cause a control apparatus to carry out the method according to claim 1.

14:

• The eccentric screw pump according to claim 13, wherein the control apparatus is set up for carrying out the method.
