I. Daily Inspection and Cleaning
1. Operational Status Inspection: Before starting the machine each day, listen for abnormal noises from the motor and reducer, and check the temperature of the casing (motor ≤ 60℃, reducer ≤ 70℃). A sudden increase in vibration may indicate stuck rake teeth or worn bearings; stop the machine and inspect.
2. Cleaning and Maintenance: Clean residual dirt from the slag discharge trough and scraper promptly to prevent fermentation, odors, or blockages.
Wipe the equipment casing and motor surface clean with a dry cloth to easily observe for oil leaks.
II. Lubrication Maintenance (Once a Month)
1. Bearing Lubrication: Add lithium-based grease to the bearing housings at both ends, filling them only 1/2 to 2/3 full. Adding too much grease can cause overheating.
Clean the grease fittings of dust before adding grease to prevent impurities from entering.
2. Chain Lubrication: Apply lubricating oil (e.g., 40# machine oil) evenly to the chain pins and rollers with a brush. Run the machine for 1-2 minutes to allow the oil to penetrate.
In humid environments or corrosive wastewater, it is recommended to use rust-preventive lubricating oil.
3. Reducer Lubrication: Regularly check the oil level. If insufficient, add the same type of gear oil (e.g., 220# medium-load industrial gear oil).
Change the oil after the first 3 months of operation, then every 6-12 months. The interval can be shortened in environments with heavy wastewater or poor environmental conditions.
III. Inspection and Replacement of Wear Parts (Monthly)
1. Rake Tooth Inspection: Check for breakage, deformation, or wear. If more than 3 teeth in a set are broken, or if wear causes increased mesh gaps, the entire set must be replaced.
When replacing, ensure proper tooth alignment and a tight fit with the mesh.
2. Chain and Sprocket Inspection: Check the chain for breakage or deformation, and the sprocket for wear. Replace any faulty parts immediately.
IV. Other Precautions
Safe Operation: Wear protective clothing, gloves, and a mask during cleaning. Operate in a location away from water sources and residential areas to avoid contamination.
Regular Cleaning: Clean the dyeing vat and filter screen frequently to prevent dye buildup.
