Pneumatic torque wrench is a kind of torque wrench with high pressure air pump as power source. Torque multipliers with three or more epicyclic gears are driven by one or two powerful pneumatic motors. The torque is controlled by adjusting the gas pressure. In order to allow a specific torque demand setting, each thing is equipped with a special air pressure first-to-torque comparison chart and proofreading report. In order to further use, the pneumatic torque wrench can be matched with a torque sensor to output more accurate torque. After obtaining the required torque, a suitable circuit system can be used to manually or actively shut down the air supply. The operation of the pneumatic torque wrench is quiet--

In order to further use, the pneumatic torque wrench can be matched with a torque sensor to output more accurate torque. After obtaining the required torque, a suitable circuit system can be used to manually or actively shut down the air supply.
Pneumatic torque wrench operation is quiet-Less than 85dB(A), absolutely no impact effect, reducing the damage to things, sleeves and locked objects. These two elements can make people who use things comfortable to operate, reduce fatigue, improve safety, and the maximum torque can reach 300,000N.m.
Pneumatic torque wrench provides accurate torque control-The repetition degree is ± 5%, equipped with sensor + solenoid valve switch, the repetition degree can reach ± 2%. Pneumatic torque wrenches are widely used in aerospace, mining, petrochemical, railway, construction, and construction due to their small size, light weight, large output power per unit weight, small reaction force, low environmental pollution, and low cost. Heavy vehicle installation and maintenance, heavy equipment loading and unloading and many other areas, especially in product production and installation lines are widely used, especially when large torque is required.
Pneumatic wrench[1] Generally divided into two categories, one is routine is very general impact wrench, one is pulse pneumatic wrench, the difference between the two is that the former can not be fixed torque, while the latter can. Pneumatic torque wrenches belong to the latter.
Application methods and matters needing attention
1. Check before use to see if the scale value is required for the installation of parts.
2. If short parts and damaged parts are found, repair them in time, otherwise they cannot be used.
3. The insert is not completely covered with nuts to stop pressing the switch.
4. The insert connection must be connected with special pins and sealed with rubber rings.
5. Stop loading and unloading the pneumatic wrench insert with wind (without closing the air valve) and cleaning the pneumatic wrench with wind.
6. All kinds of equipment without the permission of the person in charge, anyone is prohibited from private operation or air supply.
7. After all kinds of equipment are used up, dial down the quick connector for cleaning, cleaning and safekeeping.
8. When using, do not overload, do not idling at high speed to prevent premature mechanical wear.
9. Each shift must inject lubricating oil 3~4 times from the inner hole of the nozzle. No. 20 engine oil can be used in summer and No. 10 engine oil can be used in winter (many are designed to be free of refueling).
