The difference between pneumatic torque wrench and pneumatic spanner

首要都是气动为驱动介质，气动扭矩扳手是能够调理扭矩，而气动扳手不能够调理扭矩，一般的气动扭矩扳手的精度能够到达5%以内，并且调理的扭矩规模大，现在比较大的扭矩能够到达12000牛米，而气动扳手主要是冲击扳手，有扭矩可是扭矩通常小，并且扭矩不是准确的，噪音较大，相比较气动扭矩扳手高，一般为进口的东西，气动扳手较低。一个带扭矩，一个不带扭矩，带扭矩的气动扳手能够操控力矩巨细，能够准确紧固螺栓。

The first is pneumatic as the driving medium, pneumatic torque wrench is able to adjust the torque, and pneumatic wrench can not adjust the torque, the general pneumatic torque wrench accuracy can reach less than 5%, and adjust the torque scale is large, now the maximum torque can reach 12,000 Nm, and pneumatic wrench is mainly impact wrench, there are. Torque is usually small, and the torque is not accurate, noise is greater, compared with pneumatic torque wrench price is higher, generally imported things, pneumatic wrench price is lower. A pneumatic wrench with torque, a torque-free, torque-free wrench can manipulate the torque and tighten the bolt accurately.

气动的只能一个劲的冲击螺栓，无法操控螺栓是够依照要求紧固,你说的这个气动扭力扳手应该就是指气动棘轮式的扳手，这个是没有扭力校对功能的，而扭矩扳手一般是用指定的扭力来锁紧螺丝，能够调理扭力的巨细,气动扭力扳手就是运用压缩空气作为动力来历啊一般的是靠人工的,假如你仅仅注重拧进的深度，或许如你所说，你要操控的是高度。那脚踏实地的讲，无论什么牌子，气动东西都是很难做到的。除非你下降气源，靠肉眼去操控旋转的圈数，进而推算出螺纹的行程。这个假如实际操作起来，很难实现的。

Pneumatic impact bolt can only be a strong bolt, can not control the bolt is enough to tighten according to the requirements, you said the pneumatic torque wrench should be refers to the pneumatic ratchet wrench, this is not a torque calibration function, and torque wrench is generally used to lock the specified torque screw, can adjust the size of the torque, pneumatic torque wrench The wrench is powered by compressed air. Generally it's manual. If you only focus on the depth of the screw, maybe as you say, you're controlling the height. It's hard to do anything on the ground, no matter what brand. Unless you reduce the gas source and control the number of revolving circles by the naked eye, then calculate the thread travel. If this is actually operated, it will be difficult to achieve.
