　　SGDD电动扭力扳手扭矩的选择和调整

　　Selection and adjustment of torque for SGDD electric torque wrench

　　1. 用户可在50-3500N.m范围内选用相应规格的SGDD电动力矩扳手。

　　1. Users can select SGDD electric torque wrench of corresponding specifications within the range of 50-3500n. M.

　　2. 控制仪表板上有开关;转矩控制旋钮。有0-10刻度值雕刻。微调旋钮的作用是对粗调两齿轮进行调整和补偿，提高扭矩控制精度。

　　2. There is switch on the control instrument panel; torque control knob. There are 0-10 scale values for engraving. The function of the fine adjustment knob is to adjust and compensate the coarse adjustment two gears, so as to improve the torque control accuracy.

　　3、调节方法:产品扭矩测试数据卡,校准参考用户,用户可以选择某一刻度值,根据所需的扭矩拧紧螺栓的操作方法,并拧紧螺栓,使用负载扳手或其他实际测量仪器的螺栓扭矩值,如果扭矩小,微调的补偿,如果差异较大,可以粗调优或通过一个级距,重复几次，以获得所需的扭矩值。

　　3. Adjustment method: product torque test data card, calibration reference user, user can select a certain scale value, tighten the bolt according to the required torque operation method, and tighten the bolt, use load wrench or other actual measuring instrument bolt torque value, if the torque is small, fine adjustment compensation, if the difference is large, coarse adjustment or through a step, Repeat several times to obtain the required torque value.

　　SGDD电动扭力扳手螺栓的拧紧操作

　　Tightening operation of SGDD electric torque wrench bolt

　　1. 安装反力支架并拧紧螺丝。打开主机，将方销孔与反力支架孔对应，装入扳手套筒，插入销孔，用橡胶圈固定。

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

　　2. 将控制仪表的转矩旋钮调整到所需的转矩值，将主机正、负开关调到正旋转位置，将螺纹接头六面扳手套盖上。

　　2. Adjust the torque knob of the control instrument to the required torque value, adjust the positive and negative switches of the main engine to the positive rotation position, and cover the hexagon wrench cover of the threaded joint.

　　3.按下电源开关，启动扳手。当反力支撑的扭力臂固定在支撑上时(支点可以是附近的螺栓或其他充当支点的位置)，螺栓开始紧固。当螺栓扭矩达到预定扭矩时，扳手自动停止，完成拧紧，松开电源开关，拧紧下一个螺栓。

　　3. Press the power switch to start the wrench. When the torsion arm of the reaction support is fixed on the support (the fulcrum can be a nearby bolt or other position acting as the fulcrum), the bolt starts to fasten. When the bolt torque reaches the preset torque, the wrench will automatically stop, complete the tightening, loosen the power switch and tighten the next bolt.

　　4. 扳手自动停止后，支撑臂通过反支撑的弹性变形力自动与支点分离，将扳手取下。当力矩臂无法脱离支点时，正、负开关可切换，电源开关扳手可点动。

　　4. After the wrench stops automatically, the support arm is automatically separated from the fulcrum through the elastic deformation force of the reverse support, and the wrench is removed. When the torque arm cannot be separated from the fulcrum, the positive and negative switches can be switched, and the power switch wrench can be inched.

　　SGDD电动扭力扳手操作注意事项(需特别注意)

　　Operation precautions for SGDD electric torque wrench (special attention required)

　　1. 接通电源前，检查电源电压与产品铭牌是否一致，是否有接地装置。当供电电压超过+10%时，应采取稳压措施，否则会影响控制精度。接地不良容易引起事故。

　　1. Before connecting the power supply, check whether the power supply voltage is consistent with the product nameplate and whether there is grounding device. When the power supply voltage is more than + 10%, voltage stabilizing measures shall be taken, otherwise the control accuracy will be affected. Poor grounding is easy to cause accidents.

　　2. 刀具使用的环境温度为-10℃-40℃，过高或过低都会影响控制精度。

　　2. The ambient temperature of the tool is - 10 ℃ - 40 ℃, too high or too low will affect the control accuracy.

　　3.螺栓的初始扭矩不应大于工具额定扭矩的70%。达到额定扭矩后，螺栓不能重新安装。

　　3. The initial torque of the bolt shall not be greater than 70% of the rated torque of the tool. When the rated torque is reached, the bolts cannot be reinstalled.

　　4. 当使用该工具拆卸螺栓时，扭矩不应大于额定扭矩。一般情况下，使用该扳手不能紧固或腐蚀严重的螺栓，以免损坏工具。

　　4. When using the tool to remove bolts, the torque shall not be greater than the rated torque. In general, the use of this wrench can not tighten or corrode serious bolts to avoid damage to the tool.

　　5. 改变旋转方向时，必须在电机停止转动后进行，工作中严禁移动正、负开关。

　　5. When changing the rotation direction, it must be carried out after the motor stops rotating. It is forbidden to move the positive and negative switches during the operation.

　　6. 当扳手自动停止时松开开关(如果开关持续打开，5秒后扳手自动启动)。4-5秒后启动扳手，否则无法启动。

　　6. Release the switch when the wrench stops automatically (if the switch continues to open, the wrench will start automatically after 5 seconds). Start the wrench in 4-5 seconds, otherwise it will not start.
