I. Daily Maintenance
1. Check Lubrication: Inspect gears, bearings, and other moving parts daily, and replenish lubricating oil (such as lithium-based grease) promptly to prevent dry friction damage.
2. Clean Equipment: Clean the dyeing vat and nozzles of residual dye before and after each shift to prevent clogging and color differences.
3. Check Sealing: Regularly check the sealing rings for aging to prevent dye leakage or contamination.
4. Safety Devices: Ensure pressure gauges and safety valves are sensitive and reliable to prevent overpressure risks.
II. Periodic Maintenance
1. Clean Filters: Clean nozzle filters weekly to prevent impurities from clogging and affecting dye liquor circulation.
2. Check Circulation Pump: Test pump flow monthly to ensure sufficient dye liquor exchange and prevent color variations or incomplete cleaning.
3. Calibrate Instruments: Calibrate temperature and pressure sensors quarterly to ensure accurate parameters.
4. Pressure Test: Conduct a pressure test on the entire machine annually to ensure equipment safety.
III. Maintenance of Key Components
1. Nozzles: Regularly check nozzle pressure (recommended 0.3-0.4 MPa). Low pressure can lead to insufficient dye liquor exchange.
2. Heating System: Check heating elements and temperature controllers to prevent temperature fluctuations from affecting dyeing results.
3. Transmission System: Check belt and chain tension to prevent slippage or breakage.
IV. Maintenance Precautions
1. Lubrication Management: Select lubricating oil according to the equipment manual; avoid mixing or excessive use.
2. Troubleshooting: Immediately stop the machine and troubleshoot any abnormalities (such as noise or vibration) to avoid operating with defects.
3. Record Keeping: Establish maintenance records, noting maintenance time, content, and replaced parts for easy traceability.
