High current in axial flow pump
Thread Content
What are the reasons for high current in an axial flow pump? How to handle it?
The reasons for high current in axial flow pumps are: 1. Operating away from the designed operating conditions； 2. Operation with ultra-high throughput ； 3. The drainage level is insufficient to meet the minimum submersion depth required by the water pump, resulting in severe cavitation and an increase in motor power. The solutions are as follows: 1. The actual operating conditions of the pump must match the design conditions ； 2. Reduce flow rate ； 3. The minimum submersion depth of the water pump operates within the allowable range for the pump.
1. Mechanical failure: Are there any issues with the pump bearings?； Problems with the motor itself ； Coupling issue 2. Is the pump clogged?
High temperature of the main shaft flow pump motor: 1. High current; 2. Phase loss; 3. Fault in the motor itself (such as damaged motor bearings). 1. Identify the cause and take action accordingly; 2. Contact an electrician to handle it; 3. Contact an electrician to handle it
Blockage of the tubes in the external cooler, too high a solid-liquid ratio, problems with pump equipment, damaged bearings, motor failures such as damaged bearings, etc；
1. Mechanical failure 2. High solid-to-fluid ratio 3. Electrical failure 4. Increased outlet resistance 5. Impeller failure in axial flow pump
