Insufficient Traffic

Propeller blade angle too small; solution: re-adjust the blade angle from scratch.

2. Debris around blades, guide vanes, or trash racks; solution: remove the debris.

3. Blade Outer Diameter Wear and Damage; Countermeasure: Replace Blades.

Abnormal Noise and Vibration

1. Intake air produces cavitation; solution: increase water intake level.

2. Severe wear on guide bearings or sleeves, and damage to rolling bearings leading to failure; Solution: Replace the guide bearings or sleeves and rolling bearings.

3. Incomplete pump foundation. The motor shaft and pump shaft are not concentric or the drive shaft is bent; Solution: reinforce at the base, realign from the start, and straighten the drive shaft.

4. Insufficient water level, poor immersion depth of the impeller; Solution: Reduce the height of the device or increase the water intake level.

5. Loose or poorly anchored fasteners and drive nuts; Solution: Inspect and tighten all bolt fasteners to reinforce the foundation.

No leaks.

Axial Flow Pump Optional Direction Not Addressed: Adjust the prime mover's rotation direction.

2. Blade Fixation Issue; Solution: Inspect the blades. Adjust the blade assembly angle of the impeller seat fixture from the beginning.

3. Siphon export height too high; Solution: Reduce height.

4. Import Blockage; Solution: Clear import debris.
