What Is a Pneumatic Torque Wrench?

Pneumatic torque wrench is a torque wrench that uses a high-pressure air pump as a power source. A torque multiplier with three or more epicyclic 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 to 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, and the output torque is more accurate. After obtaining the required torque, the air supply can be shut off manually or automatically using a suitable circuit system.

Pneumatic wrenches are generally divided into two categories, one is conventional, which is very common, but the other is not the former.

In the production line or when a large number of nuts have to be locked, choosing a pneumatic torque wrench with a power unit can save a lot of work time and labor, and effectively improve work efficiency.

The operation of the pneumatic torque wrench is quietbelow 85dB (A), absolutely no impact, reducing the damage to the tool, the sleeve and the locked object. These two factors can make the user of the tool comfortable and reduce the operation. Fatigue, improved safety, torque up to 300,000Nm.

Pneumatic torque wrench provides precise torque control-repeatability is ± 5%, equipped with sensor + solenoid valve switch, repeatability can reach ± 2%.

Pneumatic torque wrench is small in size, light in weight and high in output power per unit weight. It can achieve high torque output,

The stable and continuous torque output of the pneumatic torque wrench makes it widely applicable to various torque control applications with and without nut connection

Where there are nuts:

Pneumatic torque wrench is suitable for tightening or removing nuts. Here are some of its applications:

Truck tire bolts, buses and large machinery; Steel frame construction;

High pressure connections, such as: pipes, boiling water pumps and pressure ducts;

Nut of engine head;

Injection head on plastic injection molding machine;

Heat exchanger;

Heavy vehicle products, such as nuts for automobile chassis and suspension devices.

Where there are no nuts:

When continuous high torque is required, a pneumatic torque wrench can be used with an energy source. Typical occasions include:

Spherical valve operation;

Large trucks and overhead mobile cranes;
