DYNAMOMETER TEST

The Well Analyzer is used with dynamometer load cells to gather dynamometer data which is processed and analyzed to determine the loading and performance of the surface unit, rod string, and the downhole pump. 

Two dynamometer load cells are available. The polished rod transducer is attached to the polished rod below the carrier bar. Generally, the pumping unit can be operating during the installation of the polished rod transducer. The horseshoe transducer is a very accurate load cell for performing a more complete dynamometer analysis including precise measurement of valve loads and mechanical torque analysis.

The accelerometer built into both dynamometers provides a compact, convenient and inexpensive technique to determine polished rod position and surface dynagraph by plotting load versus position. A downhole pump dynagraph is calculated for determination of pump performance. Traveling and standing valve tests can be performed. The horseshoe transducer can be used to obtain a mechanical torque analysis on the gearbox. A permissible load diagram is displayed. Motor current is acquired and displayed for determination of motor loading and gearbox balancing. An optional motor power sensor is available.
