沖擊扳手適用于普通螺栓，固定力矩扳手適用于高強(qiáng)度螺栓(大陸角)初、終緊固;該扳手適用于高強(qiáng)度螺栓(李子)的緊固。
The impact wrench is suitable for ordinary bolts, and the fixed torque wrench is suitable for the initial and final fastening of high strength bolts (Continental angle); The wrench is suitable for fastening high strength bolts (plums).
注:電動(dòng)沖擊電動(dòng)扳手工作效率高，一般每分鐘沖擊1000次以上。
梅花型高強(qiáng)螺栓的初緊固可采用固定力矩電動(dòng)扳手或沖擊扳手進(jìn)行。大六角高強(qiáng)螺栓的施工工藝一般對(duì)初緊力矩精度要求較高。
Note: the working efficiency of electric impact wrench is high, generally more than 1000 times per minute. Fixed torque electric wrench or impact wrench can be used for initial tightening of high strength box bolts. The construction technology of large hexagon high strength bolt generally requires high accuracy of initial tightening torque.
不需要檢查扭矩-剪切電動(dòng)扳手。
There is no need to check the torque shear electric wrench.
與固定扭矩電動(dòng)扳手不同，扭剪電動(dòng)扳手需要驗(yàn)證扭矩的準(zhǔn)確性以及是否準(zhǔn)確。
Different from the fixed torque electric wrench, the electric wrench of torsion shear needs to verify the accuracy and accuracy of torque.
