ZMDE Shot Blasting Machine Maintenance Guide
Daily Maintenance and Inspection
1. Check Fasteners: Inspect all bolts on the shot blasters and motors for tightness. Tighten any loose bolts immediately.
2. Wear Parts Inspection: Examine the wear-resistant parts inside the shot blaster and the protective plates within the blast chamber. Replace any worn parts as needed.
3. Blade Inspection: Inspect the blades and replace them when they are worn down to half their original thickness.
4. Directional Sleeve Check: Verify that the directional sleeve pointer is correctly positioned.
5. Blast Machine Doors: Ensure that all maintenance doors on the shot blasting machine are securely closed.
6. Dust Removal System: Check for leaks in the dust removal pipes and inspect the filter bags for dust or damage. Replace damaged filters promptly.
7. Separator Inspection: Check for debris or blockages on the separator's spiral shell and filter screen. Clean as necessary.
8. Flow Curtain Uniformity: Ensure the flow curtain in the separator is uniform and complete.
9. Shot Control Valve: Verify that the shot control valve is closed.
10. Switches and Indicators: Inspect all limit switches and proximity switches for proper operation. Ensure all signal lights on the control panel are functioning correctly.
11. Motor Current: Check that the motor current for the shot blaster is within the rated range.
12. Electrical Cabinet Cleaning: Clean the dust from the electrical control cabinet.
13. Seals and Guards: Inspect the seals on the shot inlet pipe, work doors, and top seals. Replace if worn to prevent shot leakage.
14. Debris Removal: Clear any debris from the bottom grid to ensure shot recycling.
15. Shot Supply: Check the shot material level in the hopper. Refill if necessary.
Weekly Maintenance and Inspection
1. Splitter Wheel: Replace the splitter wheel if worn down by more than 3mm.
2. Directional Sleeve: Replace the directional sleeve if its opening has increased by more than 6mm.
3. Protective Plates: Inspect the protective plates of the shot blaster for severe wear and misalignment.
4. Dividers and Chutes: Check the wear on dividers and chutes and replace them if necessary.
5. Recycling System: Inspect the fine powder and large particle tubes for recoverable shot material.
6. Elevator Belt: Check the tension, bolts, and joints of the elevator belt. Adjust and replace as needed.
7. Auger Inspection: Check for foreign objects and wear in the auger.
8. Bottom Grid: Repair any leaks in the bottom grid.
9. Pipe Joints: Inspect pipe joints to prevent leaks of air and dust.
10. Dust Collector: Check the dust on the dust collector bag and use the pulse blowback mechanism in time.
11. Compressor Maintenance: Drain water from the air compressor, storage tank, and oil-water separator.
Monthly Maintenance and Inspection
1. Shot Control Valve Adjustment: Adjust the shot control valve to maintain the motor current between 12A and 14A.
2. Drive Chain: Adjust and lubricate the drive chain.
3. Elevator Belt Tension: Check and adjust the tension of the elevator belt. Tighten bucket bolts as needed.
4. Gearbox Lubrication: Check the lubricant level in the gearbox and add the appropriate grease if necessary.
5. Electrical Contacts: Check the contact status of each AC contactor and switches.
6. Wiring Check: Tighten any loose wires in the power and control systems.
7. Motor Test: Run individual motor tests to check for normal sound and current levels. Each motor should run for at least 5 minutes.
8. Fan and Duct Inspection: Inspect the wear and attachment of fans and ducts.
9. Lubrication: Lubricate the bearings on the elevator, separator, and auger once a month with #2 calcium-based grease.
10. Compressor Oil Change: Change the oil in the air compressor monthly.
Quarterly Maintenance and Inspection
1. Bearing and Electrical Box: Inspect bearings and electrical boxes. Add new grease as needed.
2. Wear Plate Inspection: Check the wear on the shot blaster's wear plates.
3. High-Speed Grease: Replace the high-speed grease in the shot blaster main shaft and motor bearings.
4. Bolt and Flange Check: Inspect all bolts and flange connections on motors, gearboxes, fans, and augers for tightness.
Annual Maintenance and Inspection
1. Complete Bearing Inspection: Inspect and lubricate all bearings, including motor bearings, with new grease.
2. Chamber Repair: Replace or weld any worn protective plates in the main chamber.
3. PLC and Inverter Check: Verify the contact reliability of the PLC and inverters.
4. Ammeter Calibration: Ensure the ammeters are displaying accurate readings.
5. Dust Collector Filters: Replace damaged filters and clean excessively dusty filters with an air gun.
6. Duct Cleaning and Repair: Perform necessary cleaning and repairs on the duct system.
