使用扳手之前先将需要的实际拧紧扭矩值预置在扳手上面,当数值相等的时候,扳手会发出警报声,扭矩扳手手柄上有窗口,窗口内有标尺,标尺上显示扭矩值的大小。

Before using the wrench, preset the actual tightening torque value required on the wrench. When the values are equal, the wrench will sound an alarm, and there is a window on the torque wrench handle with a ruler inside, which displays the size of the torque value.

Before using the wrench, preset the actual tightening torque value required on the wrench. When the values are equal, the wrench will sound an alarm. There is a window on the handle of the torque wrench, and there is a ruler inside the window, which displays the size of the torque value. There are two types of torque wrenches: fixed value type and preset type. The preset adjustable torque wrench refers to the adjustable pre tightening value of the torque, which users can adjust according to their needs. Before using the wrench, the actual tightening torque needs to be preset on the wrench, when tightening threaded fasteners.
如果实际扭矩与预紧扭矩值相等,扳手就会发出警报声,此时停止扳手,扳手释放后会自动的设定预紧扭矩值,为下一次工作做准备;还有一种方法是自己看扳手上的扭力值,扳手手柄上有一个窗口,窗口内的标尺会标出具体的扭力值。设定预紧扭矩值的方法是先松开扭矩扳手尾部的尾盖,然后旋转扳手尾部手轮就行。使用扭矩扳手一般要注意使用前要进行检查,装配零件是否达到所需数值;查看是否有零件缺失等事项。
If the actual torque is equal to the pre tightening torque value, the wrench will sound an alarm, stop the wrench, and after the wrench is released, it will automatically set the pre tightening torque value to prepare for the next work; Another method is to check the torque value on the wrench yourself. There is a window on the wrench handle, and the ruler inside the window will indicate the specific torque value. The method to set the pre tightening torque value is to first loosen the tail cover of the torque wrench, and then rotate the handwheel at the tail of the wrench. When using a torque wrench, it is generally important to check whether the assembled parts have reached the required value before use; Check for any missing parts or other issues.
