Pay attention to the仪表display parameters, ensuring that the current and voltage are within the normal range.

2. Be aware of any vibration or increased noise in slurry pumps, look for leaks, and check if there's any belt reversal at the slurry pump operation site.

3. Regularly check the pressure and flow of shaft seal water during operation and adjust the packing gland or replace the packing promptly. This ensures that a small amount of clean water always passes through the shaft.

4. Regularly inspect the operation of the bearing assembly. If the bearing heats up upon startup, it is advisable to shut down the pump and wait for the bearing to cool down before restarting. Prior to shutting down, the pump should be operated for a while with clean water to flush out the sludge passing through it, followed by closing the pump, gates, and stuffing box water seal in sequence. If the bearing continues to overheat severely and the temperature keeps rising, it is necessary to disassemble and inspect the bearing assembly to identify the cause. Generally, bearing overheating is due to excessive lubricating oil or impurities in the oil. The amount of bearing grease should be appropriate and clean, and it should be added regularly.

5. The performance of the slurry pump varies and efficiency decreases as the gap between the impeller and the shroud increases. Therefore, it is necessary to adjust the impeller forward in time to maintain a certain gap, ensuring the pump operates properly. When the pump wears down to the point where it no longer meets the system requirements, replace the wear parts.

6. Keep the slurry pump operating area clean to prevent operators from slipping or scraping and getting injured.
