When using a steel pipe external wall shot blasting machine, the following precautions should be taken to ensure safe operation, improve work efficiency, and extend the equipment's lifespan:


1. Equipment Inspection and Preparation
- Pre-Operation Check: Before each use, inspect key components such as the shot blasting wheel, blades, conveyor belt, and dust removal system to ensure they are in good condition and free from looseness, wear, or damage.
- Quality of Shot Media: Use shot or grit that meets standards, and avoid low-quality materials to prevent affecting cleaning results or damaging the equipment.
- Lubrication Maintenance: Ensure that moving parts (e.g., bearings, chains) are adequately lubricated to reduce wear.


2. Operational Standards
- Parameter Settings: Adjust the speed of the shot blasting wheel, blasting angle, and shot flow rate according to the material, diameter, and surface condition of the steel pipe to avoid over-treatment or incomplete cleaning.
- Uniform Feeding: Ensure that steel pipes are fed evenly into the blasting chamber to prevent accumulation or jamming, which may affect processing results.
- Monitor Operation: During operation, closely monitor the equipment's status and promptly stop the machine for inspection if abnormalities (e.g., noise, vibration, temperature rise) are detected.


3. Safety Precautions
- Wear Protective Gear: Operators must wear protective goggles, masks, gloves, etc., to prevent shot splashing or dust inhalation.
- Equipment Protection: Ensure safety devices (e.g., protective covers, emergency stop buttons) are intact to avoid accidents.
- Prohibit Improper Operation: Never perform maintenance or cleaning while the equipment 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 blockage.
- Regular Cleaning: Regularly clean residues in the blasting chamber, conveyor belt, and dust collector to maintain equipment cleanliness.


5. Maintenance and Upkeep
- Regular Inspections: Periodically inspect wear-prone parts such as the shot blasting wheel, blades, and conveyor belt, and replace them as needed.
- Lubrication Maintenance: Follow the equipment manual to perform regular lubrication maintenance, ensuring smooth operation.
- Maintenance Records: Keep maintenance records documenting each inspection, upkeep, and repair for easy tracking of equipment status.


6. Environment and Workspace
- Clean Workspace: Keep the area around the equipment clean to avoid clutter that may affect operation.
- Good Ventilation: Ensure the workspace is well-ventilated to reduce dust accumulation and protect operators' health.


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


8. Abnormality Handling
- Prompt Shutdown: If abnormalities (e.g., unusual noise, vibration, temperature anomalies) are detected, stop the machine immediately for inspection and restart only after resolving the issue.
- Fault Troubleshooting: For faults that cannot be resolved independently, contact professional maintenance personnel promptly and avoid unauthorized disassembly or repair.


Summary
The efficient operation of a steel pipe external wall shot blasting machine relies on standardized operations, regular maintenance, and strict safety management. By following the above precautions, not only can equipment efficiency be improved, but its lifespan can also be extended, ensuring operator safety and creating greater value for the enterprise.
