Wind power industry large high strength bolt detector

      Wind power industry large-scale high-strength bolt detector with reference to NB/T31082-2016 "Wind turbine tower with high-strength bolt connection pair", GB/T3098.1-2010 "Fasteners mechanical properties bolts, screws and studs" GB50205-2001 "Steel structure engineering acceptance Code" design and manufacture, It can test, display and print the axial force, torque and torque coefficient of large hexagon head high-strength bolt connection pair (M33-M64). When the axial force reaches the value specified in the standard, the detector emits a buzzer and records the peak value of the detection data. After the device stays for 1 second, the sample is automatically reversed and released. At the same time, the detector automatically calculates the torque coefficient according to the detected axial force and torque and automatically displays it. When a group of tests are completed, the detector automatically calculates the average axial force, average torque, average torque coefficient, standard deviation and coefficient of variation of N specimens. The pre-tightening force of the torsional shear bolt can also be tested after the wrench is equipped. The equipment is mainly used for the detection of steel structures and large wind power bolts!
