Shot blasting machines are tools used to clean, smooth, or polish metal surfaces. Maintaining and repairing these blasting machines is important so they can work in the long run. Regular maintenance can keep the machine running smoothly and reduce costly repairs. Read the post below to learn some effective tips to keep your shot blasting equipment maintained.
Why Shot Blasting Machine Maintenance is Necessary?
Like any machine, a shot blasting machine has components that can wear out over time. Without regular care, these parts can break down. This damage can cost you time and money. So, it’s important to maintain your blasting equipment to extend the life of the machine.
Daily Maintenance Tips For Shot Blasting Machines
- Check for any loose fasteners on components and tighten them quickly.
- Examine the abrasion on all interior parts and the backplate, and replace any worn parts right away.
- Inspect the blade and replace it when it is half worn.
- Check the directional cover pointer to verify it is in the correct place.
- Make sure that the testing door is closed.
- Check the dust pipes to ensure there is no leaking; remember that dust and filter damage are not permitted.
- Inspect the spiral components on the separator, and if there are any sundries or filters, clean them promptly.
- Inspect the shutting of the electronic brake valve.
- Check that the current of the shot motor is within the rated range.
- Clean the dust from the electrical control box of the shot blasting machine.
- Remove the pieces from the bottom grid and confirm the recall of steel grits and shoots.
- Check the overall amount of abrasives and, if necessary, apply more as needed.
Weekly Maintenance of the Shot Blasting Machine
- Inspect the backplate to prevent significant attrition and malposition.
- Check the tension of the V-belt; it should be pushed approximately 10mm, otherwise it should be changed.
- Inspect the powder tube and pipelines to check that there are certified steel grits and shots for recycling.
- Check the hoisting equipment, including the belt tension, bolt tightness, and joint location.
- Inspect the abrasion to verify there are no contaminants or attrition on the screw vessel.
- Check pipe joints to eliminate dust and leaks.
- Remove dust from the filter cartridge and use the pulse cleaning mechanism.
- Lubricate all four blasting bearings once a week.
- Drain the water from the air compressor, oil-water tank, and separator once a week.
Monthly maintenance of the shot blasting machine
- Tighten and lube the driving chains.
- Check and adjust the bucket elevator’s belt; tighten the fasteners.
- Check the lubricant in the gear; if it is less than the prescribed amount, add more oil as needed.
- Inspect and clean the AC contactor and switch contact state.
- Check the condition of the power and control, and tighten them if necessary.
- Check each motor individually, including whether the sound is normal and the no-load current, with a testing time of at least 5 minutes.
- Change the oil in the air compressor once every month.
Annual maintenance of the shot blasting machine
- Check the lubrication of all bearings and apply fresh grease.
- Replace or weld the protective shielding in the main chamber.
- Verify the contact reliability of the PLC and the inverter.
- Check the accuracy of the ammeter.
- Inspect the dust filter cartridge and replace if required. If the dust is sticky, use the air cannon to remove it.
- Clean and repair the tuyere pipe as needed.
