Pneumatic torque wrench use methods and precautions.

Pneumatic torque wrench is a kind of torque wrench with high pressure air pump as power source. A torque multiplier with three or more layers of epicyclic gears is driven by one or two powerful air motors. Torque is controlled by adjusting the gas pressure. To allow specific torque requirements to be set, each tool is equipped with a barometric control chart and correction report on torque. And for further applications, the pneumatic torque wrench can be combined with a torque sensor, when the output torque is more accurate. When the required torque is obtained, the air source can be turned off manually or automatically using a suitable loop system.
Pneumatic torque wrench use method and precautions:
1. Check before use to check whether the scale value is the required value for assembly parts.
2. If it is found that the missing parts and damage are repaired in time, otherwise it cannot be used.
3. The sleeve does not cover the nut. Do not press the switch.
4. The socket joint must be joined with special pins and sealed with rubber rings.
5. Do not load and unload pneumatic wrench socket and clean pneumatic wrench with air.
6. All kinds of equipment without the permission of the responsible person, no one is allowed to start or supply air without authorization.
Seven. After all kinds of equipment is used up, remove the quick connector to clean it and keep it properly.
8. When using, do not overload, do not idling at high speed, to prevent premature mechanical wear.
9. Each shift must be injected with lubricating oil from the inner hole of the nozzle 3 to 4 times, the summer can use No. 20 oil, winter with no. 10 oil (many designed to avoid refueling).
10. If the secondary impact is found in use, it should be stopped immediately for inspection, it is prohibited to disassemble on the scene (refers to the unclean place), and it should be sent to the repair department for maintenance in time.
Pneumatic torque wrench with its small size, light weight, large output power per unit weight, can achieve large torque output, small reaction force, small environmental pollution, low cost advantages, widely used in aerospace, mining, petrochemical, railway, construction, heavy vehicle assembly and maintenance, heavy equipment loading and unloading and many other fields, especially in the product production assembly line has been widely used. Especially if you need a lot of torque.
