Answer:
Step-by-step explanation:
1. Compressed air source: The first requirement for using a pneumatic impact wrench is access to a compressed air source. This can be a pneumatic air compressor or a compressed air tank.
2. Air hose: The compressed air is delivered to the impact wrench through an air hose. The air hose connects the impact wrench to the compressed air source.
3. Trigger operation: To operate the pneumatic impact wrench, you need to press and hold the trigger. When the trigger is pressed, it allows the compressed air to flow into the wrench.
4. Hammer mechanism: Inside the impact wrench, there is a hammer mechanism that converts the flow of compressed air into rotational motion. The hammer mechanism consists of a rotor and a set of hammer pins.
5. Rotational motion: As the compressed air flows into the wrench, it pushes against the rotor and causes it to spin. The spinning rotor transfers energy to the hammer pins.
6. Hammering action: The hammer pins, also known as anvils, strike against an output shaft or socket, creating a rapid hammering action. This hammering action generates the torque required to loosen or tighten fasteners.
7. Torque adjustment: Many pneumatic impact wrenches have a torque adjustment feature. This allows you to control the amount of torque applied to the fastener. By adjusting the torque setting, you can prevent over-tightening or stripping of the fastener.
8. Impact sockets: To effectively use a pneumatic impact wrench, you need to use impact sockets. These sockets are designed to withstand the high torque and hammering action produced by the impact wrench.
