I. Daily Maintenance (After each shift or each run)
1. Clean the dyeing tank and nozzles. Immediately after dyeing, drain the dye liquor and rinse the inner wall of the dyeing tank, nozzles, filters, and circulation pipelines with clean water to prevent residual dye crystals from clogging the channels.
2. Check the sealing system. Check that the cylinder door seals are intact and free of aging cracks to ensure airtightness and prevent leakage during high-temperature and high-pressure operation.
3. Clean the filter device. Remove and clean the filter screen to prevent fiber debris and impurities from accumulating and affecting the uniformity of dye liquor circulation.
II. Regular Lubrication and Mechanical Inspection (Weekly/Monthly)
1. Lubricate key components. Apply high-temperature resistant grease to friction parts such as the main pump bearing, guide roller, chain, and gears to maintain smooth operation.
2. Check the condition of fasteners. Confirm that bolts, nuts, and connectors are not loose, especially at the connection between the circulation pump and the frame, to prevent vibration-induced malfunctions. 3. V-belt Tension Adjustment: Check the tension of the transmission V-belt. Too loose a belt will result in insufficient power transmission, while too tight a belt will accelerate wear. Maintain appropriate tension.
III. Periodic Deep Maintenance (Every 3–6 Months)
1. Comprehensive Shutdown Inspection: After shutdown, conduct a systematic inspection of the entire machine, including checking the electrical control system, temperature sensor, pressure gauge, safety valves, etc., to ensure they are functioning properly.
2. Heat Exchanger Cleaning: Disassemble and clean the heat exchanger to remove scale or dye deposits, improving heat exchange efficiency and preventing inaccurate temperature control.
3. Replace Wear Parts: Replace wear parts such as seals, filters, and nozzle bushings according to usage frequency to prevent sudden shutdowns.
IV. Safety and Environmental Management
1. Prohibited Operation Under Pressure: Before starting the cylinder, ensure the pressure has been completely released to prevent burns from hot liquid splashes.
2. Corrosion and Rust Prevention Treatment: When not in use for extended periods, apply surface protection to stainless steel components, drain water, and dry the pipelines to prevent internal corrosion.
3. Record maintenance logs: Establish equipment maintenance files, record the time, content and abnormal situations of each maintenance, so as to facilitate traceability and management.
