1. Daily Inspection and Cleaning
1. Sealing System Maintenance
Check the seals before and after each use (for wear, cracks, or hardening). Clean with anhydrous ethanol or a laboratory-grade detergent, avoiding corrosive solvents.
After cleaning, thoroughly dry the seal to prevent residual moisture from causing material expansion or seal failure.
2. Lubrication Management
Check the bearing temperature rise (≤35°C) every shift and change the lubricant regularly (recommended every 500 hours).
The mechanical seal fluid level should be checked daily to ensure it does not fall below the lower limit mark.
3. Grinding Media Control
Maintain a 40% void ratio in the media filling volume and regularly screen the crushing media (for example, the diameter of the glass beads should be ≥2 times the width of the separation screen slot).
2. Maintenance of Key Components
1. Dispersion Disc and Screen
Replace the dispersion disc if it is worn more than 1/4 of its thickness or if the outer edge thickness is less than 2mm. Clean the screen immediately if it becomes clogged.
Avoid prolonged idling with low-viscosity materials to reduce cylinder wear. 2. Cooling and Sealing System
Maintain cooling water pressure at 0.2-0.3 MPa to prevent overheating due to water outages or blockages.
Regularly replace seals (such as the dynamic and static seals of mechanical seals) to prevent leakage and contamination.
III. Shutdown and Long-Term Storage
1. Pre-Shutdown Treatment
Thoroughly clean the grinding chamber and piping, and drain the cooling water to prevent ice buildup and damage to the equipment.
Seal all openings (such as the feed and discharge ports) to prevent dust from entering.
2. Long-Term Storage
Store the seals in a cool, dry place, away from direct sunlight and extreme temperatures.
Store the equipment in a dry, well-ventilated environment, and apply anti-rust oil as needed.
IV. Safety Operating Procedures
Operation with faults or overload is prohibited. Abnormal vibration or response requires immediate shutdown and inspection.
Operators must be familiar with emergency shutdown procedures and stay away from high-speed equipment.
