To operate a pass-through shot blasting machine correctly, a series of detailed steps and precautions must be followed. The following is a comprehensive operation guide:
I. Pre-Operation Inspections
- Electrical Circuit Check: Carefully inspect all electrical connections to ensure they are secure and free of loose joints.
- Crane Button Check: Verify that all buttons on the crane control panel are functioning properly.
- Shot Media Check: Inspect the shot media (iron sand) for caking and ensure an adequate supply.
- Usage Log Review: Check the machine's maintenance and usage records from the previous operation.
II. Motor Installation and Fixing
- Mounting: Secure the motor onto the hanger beam's shelf, ensuring it is horizontally balanced and the beam is vertical.
- Stability Check: Confirm the motor does not or shift during operation.
III. Operation Procedures
A. Startup Preparation
- Open the control panel, switch on the main air circuit breaker, and close the panel.
- Ensure the emergency stop switch is in the "ON" position.
- Turn the power switch clockwise to "ON."
B. Hanger Beam Operations
- Use the crane control to move the hanger beam left.
- Lower the beam until it touches the ground and align it.
- Attach workpieces to the beam's shelf.
- Raise the beam and move it right toward the shot blasting chamber, slowing down as it enters to ensure alignment.
C. Shot Blasting Machine Operations
- Close the chamber door and secure the locking pins.
- Start the dust extraction fan.
- Activate the hanger rotation (forward for 5 minutes, then reverse every 5 minutes).
- Start both shot blasting wheels simultaneously.
- Engage the elevator to maintain shot media circulation.
- Limit each operation cycle to 10–15 minutes, ensuring the motor current does not exceed the rated value (e.g., 22A).
D. Shutdown Procedures
- After the cycle, turn off the elevator, shot blasting wheels, and hanger rotation.
- Wait 5 minutes before shutting down the fan.
- Turn off the power switch.
- Open the chamber door, move the hanger to the doorway (without exiting), and clean residual shot media from the workpieces and shelf.
- Remove the workpieces after moving the hanger outside the chamber.
IV. Precautions
A. Daily Maintenance
- At the end of each shift, activate the vibration device for 5 minutes to prevent shot media caking.
- Clean debris from the separator screen.
B. Safety Checks
- Ensure the chamber is empty and all access doors are securely closed before operation.
- Monitor workpiece movement for slippage or misalignment.
- Check for abnormal vibrations, noises, or overheating in the shot blasting wheels and motors.
C. Prohibited Actions
- Never process wet workpieces.
- Avoid adjusting the shot media control valve during operation.
D. Personal Protection
- Wear full protective gear when accessing the machine's upper parts.
E. Work Environment
- Keep the workspace clear of clutter to prevent accidents.
Conclusion: Correct operation of a pass-through shot blasting machine requires meticulous preparation, strict adherence to procedures, and rigorous safety measures. Following these guidelines ensures efficient machine operation and high-quality workpiece treatment.
