Abstract (en)
[origin: CA3159532A1] The invention relates to a method for determining operating properties of a drill-rod borehole pump (1), comprising a pump head (110), which is connected to a kinematics converter (120) via a drill rod (5, 10), and the kinematics converter (120) is driven by an electric motor (3), and furthermore a measuring means (130) is provided for measuring the power consumption of the motor (3) during operation of same, said method comprising the steps of: a) measuring the current consumption and the operating voltage of the motor (3) over at least one pump cycle, with which four operating phases of the borehole pump (1) can be associated in each case, and determining the power consumption of the motor (3) therefrom; b) determining, for one pump cycle, a period and a maximum of the power consumption that corresponds to the torque maximum of the borehole pump (1); c) determining a reference phase angle for the kinematics converter (120) with the aid of the properties of the kinematics converter (120) and the power consumption of the motor (3); d) ascertaining a torque curve from the power consumption of the motor (3) with the aid of the properties of the kinematics converter (120); e) determining the operating properties of the delivery pump (1) from the torque curve using the period and the reference phase angle.
