Electrical Faults in Centrifugal Pumps

Some electrical faults from the centrifugal pump can also cause problems. Pump failures may not be due to fluid or mechanical problems only; electrical problems can be one of the main causes of failure of many things. Electrical faults in centrifugal pumps may be as follows;
• If the pump draws excessive power, its speed may be too high.
• If the pump draws excessive power, its speed may be too high.
• The pump may be operating below the label pressure.
• There may be a problem due to system height. For example, pressing too much fluid.
• Mechanical damage to the motor and pump may have occurred. This mechanical damage can be caused by a bent shaft, friction in rotating parts, or packing that is too tight.
• The lubricating fluid may be too heavy. Incorrect lubrication of the drive element can also cause a malfunction.
• Voltage may be low, electrical connection clamps may be loose.
There may be no problem with the operation of the pump. It may not be a sign of malfunction. However, the pump may stop after a while. Stopping or not flooding the pump may be due to the following reasons;
• There may be an air leak in the suction part. If there is a possibility of such leakage, the packing and suction line should be checked.
• There may be an air leak in the suction part. If there is a possibility of such leakage, the packing and suction line should be checked.
• If there is not enough water in the suction chamber, the water in the chamber will decrease when the pump starts to suck. Therefore, the pump will suck air. To prevent this, the water needed by the pump should always be available.
