Usage      
 The high-strength bolt detector (JW-500DP) is designed and manufactured in accordance with the relevant requirements of GB50205-2020 "Code for Acceptance of Steel Structure Engineering". Bolts for re-inspection shall be randomly selected from the bolt batches to be installed at the construction site, and 8 sets of connection pairs shall be selected for re-inspection in each batch. The measuring instruments used for the retest of the torque coefficient of the connection pair shall be calibrated before the test, and the error shall not exceed 2%. Each connection pair should only be tested once, and should not be reused. When the washer rotates during tightening, the connection pair should be replaced and the test should be repeated. The retest of the torque coefficient of the connection pair should insert the bolt into the high-strength bolt tester. While measuring the bolt pretension P, the torque value T on the applied working nut should be measured, and the torque coefficient K should be calculated.
When carrying out the torque coefficient test of the connection pair, the bolt pretension value should meet the requirements of Table B.0.4.

This model is computer controlled with English Software Operating. 

The automatic high-strength bolt detector (JW-500DP D) can detect, display and print the axial force, torque, and torque coefficient of the large hexagon head high-strength bolt connection pair (M16, M20, M22, M24, M27, M30). When the axial force reaches the value specified in the standard, the tester will beep and record the test data. After the device stays for 1 second, it will automatically reverse to loosen the sample. At the same time, the tester will automatically calculate the torque coefficient based on the detected axial force and torque. And automatically display; when a set 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 test pieces; the control system can cycle through 1000 sets of data Update storage and can read and print at any time.
 
In addition, the pretension of the torsion shear type bolt connection pair (M16, M20, M22, M24, M27, M30) can also be tested (optional). When the torx head is twisted, the pretension of the bolt can be recorded and used as a set of tests. After finishing, the tester automatically calculates the average pretension, standard deviation and coefficient of variation of N test pieces. The horizontal structure microcomputer-controlled high-strength bolt detector is equipped with torsion shear wrenches to realize the torsion shear function. The specifications include M16-30 six specifications of wrenches and corresponding sleeves. During the test, it is no longer loaded by the host motor, but passed Wrench loading, the equipment collects the pre-tension from time to time, records and analyzes the test results, after processing, the test results can be displayed and printed directly.

Testing Principle
The detection of steel structure large hexagon bolts is to connect two sensors through the controller to collect the axial force and torque of the sample. The two sensors bear the combined force of the sensors through the combination of mechanical structure to ensure simultaneous loading and unloading at the same time. When the set standard pre-tension value is reached, the torque coefficient under the corresponding torque is recorded and calculated; the detection of torsion shear type high-strength bolts is also connected to the axial force sensor through the controller, and the axial force of the sample is collected. When the plum blossom head is twisted When, record the tightening axial force.


8 Samples can be tested
