氣動扭矩扳手和氣動扳手的底子區別
The difference between pneumatic torque wrench and pneumatic spanner
首要都是氣動為驅動介質，氣動扭矩扳手是能夠調理扭矩，而氣動扳手不能夠調理扭矩，一般的氣動扭矩扳手的精度能夠到達5%以內，并且調理的扭矩規模大，現在比較大的扭矩能夠到達12000牛米，而氣動扳手主要是沖擊扳手，有扭矩可是扭矩通常小，并且扭矩不是準確的，噪音較大，相比較氣動扭矩扳手高，一般為進口的東西，氣動扳手較低。一個帶扭矩，一個不帶扭矩，帶扭矩的氣動扳手能夠操控力矩巨細，能夠準確緊固螺栓。
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.
氣動的只能一個勁的沖擊螺栓，無法操控螺栓是夠依照要求緊固,你說的這個氣動扭力扳手應該就是指氣動棘輪式的扳手，這個是沒有扭力校對功能的，而扭矩扳手一般是用指定的扭力來鎖緊螺絲，能夠調理扭力的巨細,氣動扭力扳手就是運用壓縮空氣作為動力來歷啊一般的是靠人工的,假如你僅僅注重擰進的深度，或許如你所說，你要操控的是高度。那腳踏實地的講，無論什么牌子，氣動東西都是很難做到的。除非你下降氣源，靠肉眼去操控旋轉的圈數，進而推算出螺紋的行程。這個假如實際操作起來，很難實現的。
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.
因而，用電動東西，帶傳感器的。經過視點設置來操控螺紋擰緊的深度。并且到了視點東西即停，具有可行性。氣動東西主要是用在精度不高，一些雜亂高精度的使用就要用到電動東西。比方汽車輪胎、發動機缸蓋等。
Therefore, electric sensors and sensors are used. The depth of thread tightening is controlled by viewpoint setting. And it is feasible to stop at the point of view. Pneumatic things are mainly used in low accuracy, some chaotic high-precision use of electric things. For example, automobile tires, engine cylinder heads and so on.
