POWER MEASUREMENT IN U-JOINT DRIVE SHAFTS ON IRRIGATION PUMPING PLANTS

ABSTRACT A commercially available torque meter has been used to measure engine torque and horsepower on approximately 800 irrigation pumping plants. By using specially designed adapter flanges, the torque meter and six temporary drive shafts can be fitted to pumping plants having 18 combinations of drive shaft capacity and length. During the measurements, engine torque has been as high as 10,000 Ibf-in. (1130 N-m), and engine speed has been as high as 3100 rpm.
