电动扭矩出现摩擦现象!

电动扭矩扳手就是以电源或电池为动力的扳手,是一种拧紧螺栓的工具。主要应用于钢结构安装,或者可以理解为专门安装钢结构高强螺栓的。在使用电动扭矩扳手过程中,出现摩擦是普遍都存在的现象。
Electric torque wrench is a wrench powered by power or battery, which is a tool for tightening bolts. It is mainly used for the installation of steel structure, or it can be understood that it is specially used for the installation of high-strength bolts of steel structure. In the process of using electric torque wrench, friction is a common phenomenon.
一般摩擦会出现好坏两方面。好的方面就是它可以使零件保持结合在一起。而坏的方面就是在扭紧时,它可能会带来错误的结果,大家在使用过程中,也要把摩擦因素考虑进去。并且如果大家在拧紧螺纹上面有损伤或者障碍的螺母或者螺栓时,也一定要注意通过损伤的部位需要附加的扭矩有多大,然后再把这个附加的扭矩加到推荐的扭矩值上面去。
Generally, there will be good and bad friction. The good thing is that it keeps the parts together. The bad aspect is that when tightening, it may bring wrong results. We should also take friction factors into account in the use process. And if you tighten the nut or bolt with damage or obstacle on the thread, you must also pay attention to the additional torque through the damaged part, and then add the additional torque to the recommended torque value.
我们在使用电动扭矩扳手的时候,用力一定要柔和均匀。大家不要用短促、冲动的力来扳动,因为如果猛拉的话,它会产生一个冲量,那么在停止用力的瞬间,就会出现螺钉或者螺栓扭过头了的现象。所以用力一定要均匀。并且相信使用过电动扳手的消费者的都知道,污染物也会妨碍到精确的扭矩值。如果电动扳手的零件或者螺孔上面有污染物的话,那么就不可能有正确的扭矩值。所以大家在日常的使用过程中,也要注意这个问题。
When we use the electric torque wrench, the force must be gentle and even. Don't use short, impulsive force to pull, because if you pull, it will produce an impulse, then at the moment when you stop the force, there will be the phenomenon that the screw or bolt is over twisted. So the force must be even. And it is believed that consumers who have used electric spanners know that pollutants can also hinder accurate torque values. If there are pollutants on the parts or screw holes of the electric wrench, it is impossible to have the correct torque value. So we should also pay attention to this problem in our daily use.
