Pneumatic impact wrench principle reference

Pneumatic torque wrench is a torque wrench powered by a high-pressure air pump. A torque multiplier with three or more revolving gears is driven by one or two powerful air motors. The torque is controlled by adjusting the gas pressure. In order to allow specific torque requirements to be set, each tool is equipped with a dedicated air pressure vs. torque comparison chart and calibration report. And for further application, the pneumatic torque wrench can be equipped with a torque sensor at the same time, so that the output torque is more accurate. After the required torque is obtained, the air supply can be closed manually or automatically using a suitable circuit system. the

Pneumatic torque wrench is a hand-held rotary pneumatic tool that can precisely set the torque and is used to complete the locking or dismounting of nuts and bolts; the control part is realized by a voltage regulator and power management system, and the mechanical part adopts a planetary gear reduction mechanism [1] The operation of the pneumatic torque wrench is quiet - less than 85dB (A), absolutely no impact, reducing damage to tools, sockets and locked objects, these two factors allow the person using the tool to operate Comfortable, reduce fatigue, improve safety, the maximum torque can reach 300,000N.m. the

Pneumatic torque wrench provides precise torque control - repeatability is ±5%, equipped with sensor + solenoid valve switch, repeatability can reach ±2%. Pneumatic torque wrench is widely used in aerospace, mining, petrochemical, railway, construction, Heavy-duty vehicle assembly and maintenance, heavy equipment loading and unloading and many other fields, especially in product production and assembly lines, are widely used, especially in occasions that require high torque.

Classification: Pneumatic wrenches are generally divided into two categories, one is conventional, that is, a very common impact wrench, and the other is pulse pneumatic wrench. The difference between the two is that the former cannot determine the torque, while the latter can. The pneumatic torque wrench belongs to the latter.
