How to use pneumatic wrench?

Pneumatic torque wrench is a torque wrench with high pressure air pump as power source. 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 demand settings, each tool is equipped with a dedicated air pressure to torque comparison chart and correction report. And for further application, the pneumatic torque wrench can be equipped with a torque sensor at the same time to make the output torque more accurate. After obtaining the required torque, a suitable loop system can be used to manually or automatically shut off the air supply.



Air Impact Wrenches is a hand-held rotary pneumatic tool, which can accurately set the torque to complete the locking or disassembly of nuts and bolts; the control part is realized by the pressure regulator and the power management system, and the mechanical part adopts the planetary gear of the reduction mechanism

The operation of the pneumatic torque wrench is quiet-less than 85dB(A), absolutely no impact, reducing damage to tools, sleeves and locked objects. These two factors can make the operation comfortable and reduce the use of tools. Fatigue, improve safety, torque Z can reach 300,000Nm.
Pneumatic torque wrench provides precise torque control-repeatability of ±5%, equipped with sensor + solenoid valve switch, repeatability of up to ±2%. Pneumatic torque wrench with its small size, light weight, large output power per unit weight, can achieve large torque output, small reaction force, low environmental pollution, low cost and other advantages, widely used in aerospace, mining, petrochemical, railway, construction, Heavy-duty vehicle assembly and maintenance, heavy equipment loading and unloading, etc., are widely used in product production and assembly lines, especially where large torque is required.
