Precautions for Operating Mixing Equipment (Overhead Mixing, Side-Entry Mixing)

The vertical mixing tank must contain at least one-third liquid material (or a liquid level approximately 0.5 meters above the lowest agitator) before starting the agitator to prevent shaft bending.

1. The vertical mixing tank must contain at least one-third liquid material (or a liquid level approximately 0.5 meters above the lowest agitator) before starting the agitator to prevent shaft bending. Before operation, connect cooling water to the mechanical seal and flush with water (some side agitator bottom covers are equipped with water flushing ports; the liquid level for side-entry agitators must cover the mechanical seal position). Verify that the sealant is fully filled.

2. Lubricate the frame bearings with grease at regular intervals (preferably weekly, especially for side agitators). During operation, monitor the reducer, motor, and frame bearings for abnormal noises. If detected, promptly investigate the cause and perform maintenance. Regularly inspect motor wiring for tightness, particularly if the motor experiences sudden, unexplained temperature increases. Check the wear condition of the shaft sleeves in the bottom bearings.

3. Regularly inspect the output shaft and bearing oil seals of the reducer for oil leakage or seepage. Check the reducer oil level and replace the lubricating oil in the reducer housing according to the reducer manual (excluding belt reducers). Switch to winter lubricating oil during cold seasons.

4. Periodically inspect the wear condition of the agitator and check for loose bolts.

5. Special Precautions: Never start the motor when the material is fully loaded or the agitator blades are buried in solid phase sediment. If a sudden power outage stops the agitator or if the agitator blades become buried in solid phase sediment after prolonged disuse, do not directly start the motor. Manually rotate the shaft or use other methods to suspend the solid phase layer before performing a variable frequency start or soft start on the motor. Failure to do so may damage the motor, reducer, and other critical components (for which our company assumes no liability).
