I. Equipment Operating Status Monitoring
Processing efficiency decrease: If the dyeing time is significantly extended or the sample uniformity decreases, it may be due to grinding wheel wear or transmission system abnormalities.
Abnormal noise/vibration: Mechanical components (such as bearings, motors) will produce abnormal noises when malfunctioning; the machine should be stopped immediately for inspection.
II. Dyeing Quality Inspection
Sample consistency: Compare with historical dyeing results; if there are color differences, patches, or uneven sand marks, it indicates that the grinding wheel or pressure system needs calibration.
Filtrate impurities: Observe the impurity content at the drain outlet; if the amount of solid particles increases, the filter screen may need cleaning or the sand medium may need replacement.
III. Mechanical Component Inspection
Grinding wheel wear: Regularly check the flatness of the grinding wheel surface; if wear exceeds 1/3, it needs to be replaced.
Lubrication system: Confirm the lubrication status of guide rails, bearings, and other parts; if dry or leaking oil, replenish or replace the lubricating oil.
IV. Maintenance Cycle Reference
Daily maintenance: Clean residual dye after each shift and check fasteners.
In-depth maintenance: A comprehensive inspection of the grinding wheel, motor, and control system is required after 500 hours of cumulative operation.
