Hook-type shot blasting machines are widely used for metal surface treatment, primarily for removing oxidation, rust, welding slag, and other impurities from workpiece surfaces to improve surface quality. To ensure safe operation, enhance work efficiency, and extend the equipment's lifespan, the following precautions should be observed when using hook-type shot blasting machines: 


1. Equipment Inspection and Preparation 
- Pre-Operation Check: Before each use, inspect key components such as the blasting chamber, blasting wheel, hook system, and dust removal system to ensure they are free from looseness, wear, or damage. 
- Abrasive Quality: Use standard steel shot or grit, and avoid low-quality abrasives to prevent poor cleaning results or equipment damage. 
- Lubrication Maintenance: Ensure that moving parts such as bearings and chains are well-lubricated to reduce wear. 


2. Operating Standards 
- Parameter Settings: Adjust the blasting wheel speed, blasting angle, and abrasive flow rate based on the material, shape, and surface condition of the workpiece to avoid over-treatment or incomplete cleaning. 
- Even Hanging of Workpieces: Ensure workpieces are evenly hung on the hooks to prevent stacking or collisions that may affect cleaning results. 
- Monitoring Operation: During operation, closely monitor the equipment's status. If abnormalities (e.g., noise, vibration, temperature rise) are detected, stop the machine immediately for inspection. 


3. Safety Precautions 
- Wear Protective Gear: Operators must wear protective goggles, masks, gloves, etc., to prevent abrasive splashing or dust inhalation. 
- Equipment Protection: Ensure safety devices such as protective covers and emergency stop buttons are intact to avoid accidents. 
- Prohibit Improper Operation: Maintenance or cleaning is strictly prohibited while the machine is running. The machine must be stopped and powered off before any such operations. 


4. Dust Removal and Environmental Protection 
- Dust Removal System Operation: Ensure the dust removal system functions properly, and clean dust promptly to prevent environmental pollution and equipment clogging. 
- Regular Cleaning: Regularly clean residues in the blasting chamber, hook system, and dust collector to maintain equipment cleanliness. 


5. Maintenance and Upkeep 
- Regular Inspections: Regularly inspect wear-prone parts such as blasting wheel blades, protective plates, and hooks, and replace them promptly if worn. 
- Lubrication Maintenance: Perform regular lubrication maintenance as per the equipment manual to ensure smooth operation. 
- Maintenance Records: Keep detailed maintenance records, documenting each inspection, upkeep, and repair for tracking equipment status. 


6. Environment and Workplace 
- Tidy Workplace: Keep the area around the equipment clean and free of clutter to avoid hindering operations. 
- Good Ventilation: Ensure the workplace is well-ventilated to reduce dust accumulation and protect operator health. 


7. Training and Operation 
- Operator Training: Operators must undergo professional training to understand the equipment's working principles, operating procedures, and emergency handling methods. 
- Comply with Regulations: Strictly follow the equipment manual and safety regulations to avoid accidents caused by improper operation. 


8. Handling Abnormal Situations 
- Immediate Shutdown: If abnormalities (e.g., unusual noise, vibration, temperature anomalies) are detected, stop the machine immediately for inspection and resolve the issue before restarting. 
- Fault Troubleshooting: For faults that cannot be resolved independently, contact professional maintenance personnel promptly. Do not attempt disassembly or repairs without authorization. 


Conclusion 
The efficient operation of hook-type shot blasting machines relies on standardized operation, regular maintenance, and strict safety management. By adhering to the above precautions, not only can equipment efficiency be improved, but the equipment's lifespan can also be extended, ensuring operator safety and creating greater value for the enterprise.
