電動扳手失效的原因可能是:運動損傷;2.電池沒電了。
The reasons for the failure of the electric wrench may be: sports injury; 2. The battery is dead.
電動扳手主要用于鋼結(jié)構(gòu)安裝行業(yè)，該行業(yè)專門從事鋼結(jié)構(gòu)高強螺栓的安裝，高強螺栓用于連接鋼結(jié)構(gòu)的觸點，通常采用螺栓組的形式。高強螺栓可分為扭剪型和大六角型兩種。標準抗扭抗剪高強度螺栓有M16、M20、M22和M24，非標準M27和M30。GbM16、M20、M22、M24、M27、M30等大六角高強度螺栓。高強度螺栓的緊固一般是先緊固后緊固，每一步都需要有嚴格的扭矩要求。大六角高強度螺栓的初始和緊固必須使用固定力矩扳手。
Electric wrench is mainly used in the steel structure installation industry, which is specialized in the installation of high-strength bolts of steel structure. High strength bolts are used to connect the contacts of steel structure, usually in the form of bolt group. High strength bolts can be divided into torsional shear type and large hexagon type. There are M16, M20, M22 and M24 high strength bolts in national standard, and M27 and M30 in non national standard. Gbm16, M20, M22, M24, M27, M30 and other large hexagon high strength bolts. The tightening of high-strength bolts is generally first tightening and then tightening, each step requires strict torque requirements. Fixed torque wrench must be used for initial and tightening of large hexagon high strength bolt.
使用效果
Application effect
電動扳手的主要作用是初始擰緊螺栓，其使用非常簡單，就是將與螺栓對準的電源開關(guān)扳動就行了。電扭剪扳手主要是端部緊固的扭剪型高強螺栓，它的使用是針對螺栓來翻轉(zhuǎn)電源開關(guān)，直到扭剪型高強螺栓的梅花端斷掉。
The main function of the electric wrench is to initially tighten the bolt. Its use is very simple, that is, to pull the power switch aligned with the bolt. The electric wrench is mainly a high-strength bolt with end fastening, which is used to turn the power switch until the quincunx end of the bolt is broken.
電動固定力矩扳手可初、末擰緊，其用途是調(diào)節(jié)扭矩，然后擰緊螺栓。電動角扳手也主要屬于一種固定力矩扳手，其用途是先調(diào)節(jié)旋轉(zhuǎn)度，然后擰緊螺栓。電動角鋼扳手是一種用于緊固鋼架角鋼螺栓的電動扳手。
The electric fixed torque wrench can be tightened at the beginning and the end. Its purpose is to adjust the torque and then tighten the bolts. The electric angle wrench also mainly belongs to a fixed torque wrench, whose purpose is to adjust the degree of rotation first, and then tighten the bolts. Electric angle spanner is a kind of electric spanner used to fasten angle steel bolts of steel frame.
