Reason 1: It is related to the material used in the pneumatic wrench
Usually, some customers will use an air compressor with 12KG air pressure in order to pursue high torque, so that the output power feels greater. However, if the air pressure is too high, and overloaded use will lead to insufficient hardness and poor material, the impact block will wear faster, and the strength will not be as strong as when it was first purchased. Therefore, the striking part of the Weimar pneumatic wrench is made of alloy steel, which is vacuum carburized and heat treated to improve the hardness and ensure more wear resistance.
Reason 2: It is related to our usage habits
Air tool maintenance personnel found that the internal blades of other brands of air wrench machinery usually have this phenomenon:
Many users do not pay attention to maintenance during use, and are not used to adding professional pneumatic lubricating oil - resulting in serious wear of the fan blades, and the torque of the pneumatic wrench will be greatly reduced. The editor reminds you that after each use of the pneumatic wrench, drop two or three drops of special lubricating oil for pneumatic tools at the air inlet (connecting end) of the wrench, and then connect the air source to idle for a few seconds.
Reason 3: The adjustment gear is not adjusted to the maximum (5th gear is the maximum). When using it, I didn't pay attention to using the adjustment gear to control the strength.
When purchasing an air wrench, give priority to choosing a well-known brand air wrench. The editor of Fengleiyi pneumatic tools will give you a tip: maintenance is better than repair! Often adding professional pneumatic lubricating oil can clean the dust inside the machine, and there will be no dust stuck. And can lubricate internal components, extending the life of the machine!
