Pneumatic adjustable torque wrench is a torque wrench with high pressure air pump as power source. One or two powerful pneumatic motors drive a torque multiplier with three or more layers of epicyclic gears. The torque is controlled by adjusting the gas pressure. In order to allow specific torque demand setting, each tool is equipped with a special air pressure comparison chart and calibration report for torque first. For further application, the pneumatic torque wrench can be equipped with a torque sensor at the same time, and the output torque is more accurate. After obtaining the required torque, the air supply can be shut down manually or automatically by using a suitable loop system.

How to calculate the force arm of the pneumatic wrench?
The torque calculation formula of rotating object is t = 9550p / n
P is power in kW, n is speed in RPM, R / min torque in NM
Torque is the product of force and arm length. For wrench, 200nm means that the distance from the wrench to the force point of the wrench is one meter, and the applied force is 200N. According to the definition of torque and lever principle, add 100N force at 2m of spanner or 400N force at 0.5m of spanner to produce 200nm torque.

What about the arm of the pneumatic wrench?
The output force of the pneumatic motor is obtained by multiplying the air supply pressure by the effective area of the pneumatic piston, and then calculated by the moment transmission of each component of the transmission mechanism. It is difficult to make clear without dimensional drawing or mapping data of internal components.
Torque is the product of force and arm length. For wrench, 200nm means that the distance from the wrench to the force point of the wrench is one meter, and the applied force is 200N. According to the definition of torque and lever principle, add 100N force at 2m of spanner or 400N force at 0.5m of spanner to produce 200nm torque. General pneumatic spanners, with a torque of more than ten to thirty or forty nm, and 200 nm, have not been heard of. They are supposed to be operated by machines
The “force” acting on the screw cap or nut is generally expressed as “torque”. If the output has to be calculated, the calculation method is the same as above, and then divide by 2. Because the force acting on the nut is a “couple”.
