摘要：A method and apparatus are provided for controlling the operation of a pump,such as a centrifugal pump, featuring steps of either adjusting the operation of the pump,
or issues a warning to a user of the pump of an undesirable operating condition, or both,based on a comparison of an actual torque value and a corrected torque value eitheralone or in combination with a further step of compensating the corrected torque valuebased on a mechanical power offset correction. The corrected torque value may include aBest Efficiency Point (BEP) torque value and may also be compensated for based on atleast the current operating speed of the pump. The pump has a controller forperforming the steps of the method. The controller can compensate the correctedtorque value based on the square of the speed change of the pump. The comparison mayinclude a ratio of the actual torque value to the corrected torque value.
