Abstract: When the water pumps run at high speed, the wired test technology is difficult to get the stressor strain signals of transmission shaft torsion deformation. However, the wireless torque sensor test technology could solve this problem better. The wireless torque testing principle had been introduced. The pump shaft torque testing method by the wireless torque sensor technology and the results analyzing method were also introduced, with No.1 and No.5 pumps of the second stage pumping station in Alashan au Nuanjingtan of Inner Mongolia as examples. The results show that the wireless method could test and record the output shaft torque accurately and promptly, and it provided an application experience for wireless technology in water pump shaft torque testing.
