Product Overview and Features
Accuracy of measured load and
position are the hallmark of equipment supplied by Lufkin Automation.
Our new Hall Effects Digital Position Transducer provides some
of the most important new features in the SAM Well Manager. This
comes about
because Lufkin Automation utilizes two digital position transducers
that provide a relationship between the speed and loading of the motor
and the position of the pumping unit.
Lufkin Automation engineers have derived an algorithm that
utilizes the geometry data from a specific model of pumping unit and
then calculates the relationship between the motor revolutions
and the revolutions of the crank arm and gear box, and thus SAM is able to very
accurately plot the exact position of the polish rod throughout the
period of the stroke.
Key Operational Features
The primary benefits derived from the
Hall Effects Digital Position transducer is the extremely accurate
plotting of the pumping unit position, but there are several other
extremely important benefits that come about when this type of position
measurement is used in the Lufkin Automation SAM Well Manager.
No other rod pump controller on the market provides these
features:
- Motor
Speed Control, controlling the pumping unit without the need for a
load cell. Can be the
primary control or a secondary redundant control method used when
there is a load cell failure.
- Belt
Slippage detection, watches for changes in motor RPM to detect
slippage and alert operator
- Shuts
well down when RPM drops due to motor overload, or due to voltage
fluctuations or phase loss.
- Shuts
down in less than one pump stroke for stuck pump.
- Calculate
the upstroke torque and set alarm limits.
- Calculate
the downstroke torque and set alarm limits.
- Protect
the gearbox and pumping unit structure from overload by setting
torque limits.
