I. Cleaning and Maintenance: Thoroughly remove residues and prevent contamination and corrosion.
1. External Cleaning: Wipe the machine surface with a soft cloth and neutral detergent, keeping it clean and dry.
2. Internal Cleaning (Drum Cleaning): This is crucial and must be performed regularly.
Removing Oligomers: Use a dedicated oligomer cleaner (such as acidic sulfite or a special cleaner) for high-temperature circulation cleaning.
Removing Alkali Scale and Calcium Salts: Use a dedicated non-strong acidic drum cleaner (such as TF-105F) to avoid corroding the inner wall of the dyeing drum.
Removing Agglomerated Dyes and Tar: Use a traditional reduction cleaning (drum preservation) process, employing sodium hydrosulfite, liquid alkali, etc.
Key Tip: Adding a suitable amount of waste cloth inside the drum during cleaning can effectively flush out "dead corners" that are difficult for the nozzle water flow to reach.
II. Regular Maintenance: Inspection, Replacement, and Lubrication
1. Replacement of Wear Parts:
Sealing Rings/Gaskets: Inspect regularly and replace immediately if aging, wear, or leakage is found.
Bearings: Inspect for wear and replace promptly.
Filters/Screens: Clean or replace regularly to ensure smooth water flow.
2. Lubrication Maintenance: Regularly apply high-temperature grease or mineral oil to moving parts such as the transmission system and bearings to ensure smooth operation.
3. System Inspection:
Electrical System: Regularly check that wires, plugs, and electrical components are securely connected and undamaged.
Pressure and Temperature Control: Check the accuracy of pressure gauges and thermometers and the proper functioning of control valves before and after use.
Rubber Roller Inspection: Inspect rubber rollers such as dyeing rollers and guide rollers to ensure they are free from deformation, cracks, or damage.
III. Daily Maintenance and Safety Standards
1. Daily Cleaning: After each workday, clean up any spilled or dripping dye liquor and wipe the equipment surfaces.
2. Environmental Requirements: Use the equipment in a dry, well-ventilated environment, avoiding interference from external moisture.
3. Safe Operation:
Prohibition of Overheating and Overpressure: Strictly adhere to the equipment's set maximum operating temperature and pressure.
Standardized Operation: Operators must be professionally trained and familiar with the operating procedures.
Emergency Preparedness: Fire extinguishers should be available in the work area. Operators should know how to handle burns, chemical splashes into eyes, and other emergencies.
IV. Maintenance Cycle Recommendations
1. Daily: Cleaning and visual inspection.
2. Weekly/Monthly: Focus on inspecting vulnerable parts (seals, bearings, filters) and lubricate them.
3. Semi-annually: Perform a comprehensive maintenance check, inspecting pressure vessels, heating elements, etc.
4. Annually: Perform a major overhaul, thoroughly inspecting, calibrating, and maintaining the equipment.
