Main application

This detector is designed and manufactured in accordance with the requirements of NB/T31082-2016 "High strength bolt connection pairs for wind turbine tower" DL/T284 "Hot dip galvanized bolts and nuts for transmission line towers and power fittings" GB/T3098.1-2010 "Mechanical properties of fasteners - bolts, screws and studs" GB50205-2001 "Acceptance code for steel structure engineering". It can detect, display and print the axial force, torque, and torque coefficient of high-strength bolt connection pairs (M33-M64) with large hexagonal heads. When the axial force reaches the standard value, the detector emits a buzzing sound and records the peak value of the detection data. After the device stays for 1 second, it automatically reverses and releases the sample. At the same time, the detector automatically calculates the torque coefficient based on the detected axial force and torque and displays it automatically; After a set of experiments is completed, the detector automatically calculates the average axial force, average torque, average torque coefficient, standard deviation, and coefficient of variation of N specimens; After equipped with a torsion shear wrench, the pre tightening force of the torsion shear bolt can also be checked. This equipment is mainly used for the detection of steel structures and large wind power bolts
