Electric torque wrench has novel structure, small volume, light weight, safety and reliability. Due to the use of static torsion structure, smooth operation, no vibration, no impact, low noise, the operator is not affected by the counter torque, so the labor intensity is low. Rated voltage 220V50 / 60Hz accuracy ± 5%.

电动扭力扳手应用行业：

Electric torque wrench application industry:

电动扭矩扳手广泛应用于栓焊结构桥梁的架设，厂房、塔架及化工、冶金、发电设备的安装。大型机械、起重设备和车辆装配作业，以及对螺纹紧固件的扭矩及轴向拉力有严格要求的场合。

Electric torque wrench is widely used in the erection of bolt welded structure bridges, the installation of factory buildings, towers and chemical, metallurgical and power generation equipment. Large machinery, lifting equipment and vehicle assembly operations, as well as occasions with strict requirements for torque and axial tension of threaded fasteners.

电动扭矩扳手螺栓的拧紧操作

Tightening operation of bolts of electric torque wrench

1、装上反力支架，并紧固螺钉。开动主机，使方头销孔与反力支架孔相对应，然后装入扳手套筒，插上销钉，并用橡胶圈固定。

1. Install the reaction support and tighten the screws. Start the main engine, make the square head pin hole correspond to the reaction support hole, then install the wrench socket, insert the pin, and fix it with the rubber ring.

2、将控制仪的扭矩旋钮调到所需扭矩值，将主机正反开关拨到正转位置，把扳手套筒套在螺纹连接件的六方上。

2. Adjust the torque knob of the controller to the required torque value, turn the positive and negative switch of the main engine to the positive rotation position, and put the wrench socket on the hexagon of the threaded connection piece.

3、按下电源开关，扳手启动。当反力支架力臂靠牢支架时（支点可以是邻近的一只螺栓或其他可作支点的位置）螺栓开始拧紧。当螺栓扭矩达到预定扭矩时，扳手自动停止，紧固完成，松开电源开关，进行下一只螺栓的拧紧工作。

3. Press the power switch to start the wrench. When the reaction support arm is against the support (the fulcrum can be an adjacent bolt or other position that can be used as a fulcrum), the bolt starts to be tightened. When the bolt torque reaches the preset torque, the wrench will stop automatically, the tightening is completed, the power switch will be loosened, and the next bolt will be tightened.

4、扳手自动停止后，靠反力支架的弹性形变力，使支架力臂自动脱离支点，取下扳手。如力臂不能脱离支点时，可拨动正反开关，点动电源开关扳手即可取下。

4. After the wrench stops automatically, the elastic deformation force of the counter force bracket makes the bracket force arm automatically separate from the fulcrum, and the wrench is removed. If the force arm cannot be separated from the fulcrum, the forward and reverse switch can be turned, and the power switch wrench can be inched to remove.

电动扭力扳手扭矩的选择与调节

Selection and adjustment of torque of electric torque wrench

1、用户可在50-3500Nm的范围内任意选择相应规格的电动扭力扳手。

1. The user can choose the electric torque wrench of corresponding specification in the range of 50-3500nm.

2、控制仪面板上有“扭矩调解旋钮”。刻有0-10个刻度值。细调旋钮的作用是在粗调两档之间进行调节补偿，以提高扭矩控制精度。（见后页）

2. There is a "torque adjustment knob" on the control panel. Engraved with 0-10 scale values. The function of fine adjustment knob is to adjust and compensate between two gears of coarse adjustment, so as to improve the accuracy of torque control. (see next page)

3、调节方法：产品出厂时带有扭矩测试数据卡片，供用户标定时参考，用户可根据所需扭矩选择某一刻度值，按拧紧螺栓的操作方法，拧紧螺栓，用测力扳手或其它测力仪器测出螺栓的实际扭矩值，若扭矩相差较小，可用细调加以补偿，若相差较大，可将粗调向上或向下调一档，反复几次即可获得所需扭矩值

3. Adjustment method: the product is provided with a torque test data card for the user's reference during calibration. The user can select a certain scale value according to the required torque, tighten the bolt according to the operation method of tightening the bolt, and use a force measuring wrench or other force measuring instruments to measure the actual torque value of the bolt. If the torque difference is small, fine adjustment can be used to compensate. If the difference is large, coarse adjustment can be made upward Or downshift one gear for several times to obtain the required torque value
