Electromagnetic ultrasonic bolt axial force detector
The electromagnetic ultrasonic bolt axial force detector BM100 mainly cooperates with traditional hydraulic wrenches, electric wrenches and other tools to realize axial force feedback control, thereby reducing the tightening coefficient of traditional torque construction tools and improving the quality of bolt pre-tightening. The products are widely used in the quality control of the torque method bolt construction process to improve the torque method construction quality. The equipment realizes communication control through wireless Bluetooth and electric wrench or hydraulic wrench. At the same time, open the Bluetooth protocol to the electric wrench or hydraulic wrench of the third-party manufacturer to realize the integration with the third-party tool.
<<< company's product
◎ This product can be used with a wrench without changing the bolt structure design. The original stretching method construction method is changed to the torque method construction, which improves the work efficiency and achieves a better fastening effect; if the original torque method construction is used, cooperate with this product When used, it becomes the "axial wrench" construction method, which can reduce the tightening factor and improve the safety factor of the bolt connection; under the condition of ensuring the same safety factor of the bolt connection, using the "axial wrench" construction can make the bolt connection design Reduce the amount of bolts or choose smaller size bolts to save costs; combine with stretching tools to further improve the construction accuracy of the stretching method;
◎ With the historical data in the "cloud data", the product can perform quick bolt axial force inspection and historical trend analysis;
◎ Wide adaptability, no coupling agent, no need to polish, the end face of the bolts with higher raised characters, small diameter (or reduced diameter) studs, bolts with hexagon sockets, bolts with concave surface can be used directly;
<<< Detection characteristics
● Help the torque wrench to feedback the bolt axial force in real time at a rate of more than 10 times per second, and control the start, stop and speed of the wrench through the feedback axial force value, so that the torque wrench can be changed from torque control to precise axial force control;
● Based on cloud data, carry out bolt axial force inspection, realize the life management from bolt construction to bolt operation and maintenance, and provide customers with scientific and reasonable operation and maintenance plans;
● If the initial value of the bolt is recorded before delivery or assembly, it can also be applied to the pre-tightening force acceptance of the bolt construction of the unit under construction; the analysis of the bolt failure problem of the in-service unit; the auxiliary verification of the bolt construction process; and the historical data , Carry out application occasions such as the bolt axial force inspection of the in-service unit;
