These issues involve the intricate mechanical, electrical, and hydraulic systems of submersible slurry pumps. Without adequate expertise, seeking professional pump equipment maintenance services or contacting the manufacturer’s technical support is advised to ensure proper and safe resolution of problems.

Troubleshooting Common Issues with Submersible Slurry Pumps
  1. Blockage or Obstruction:

Issue:

Submersible slurry pumps might experience reduced flow or complete stoppage due to blockage at the inlet.

Solution:

Cleaning the pump body: Conduct regular maintenance by inspecting the pump internals to clear any blockages. Utilize high-pressure water for flushing to eliminate residual particles.

Mesh screens and filters: Install appropriately sized and precise mesh screens or filters to prevent large particles, thereby anticipating blockages.

 

  1. Leakage from the Pump:

Issue:

 Pumps may leak due to aging, wear, or improper installation of sealing components.

Solution:

Inspecting the sealing system: Regularly examine the integrity of seals, including O-rings, packing seals, and mechanical seals, and replace or reinstall them as necessary.

 

  1. Unusual Noise or Vibration During Operation:

Issue:

 Anomalies in noise or vibration could stem from incorrect installation, imbalanced impellers, bearing faults, or foreign objects within the pump.

Solution:

Balancing impellers and calibrating bearings: Utilize specialized equipment to balance impellers and assess bearing wear, replacing them if required.

Cleaning and inspecting pump internals: Conduct routine cleaning to ensure the absence of foreign objects or damaged components within the pump.

 

  1. Decreased Performance:

Issue:

Reduction in flow rate or head could result from impeller wear, pump body erosion, or changes in the materials being processed.

Solution:

Check impeller condition: Regularly inspect impeller wear and replace it as needed to restore performance.

Internal pump inspection: Periodically check wear on internal parts like the pump casing, bearings, and seals, performing necessary repairs or replacements.

 

  1. Electrical Issues:

Issue: Difficulty starting, frequent shutdowns, or unstable operation of the electric motor.

Solution:

Motor inspection: Check the electric motors condition, including insulation, bearings, and windings, and conduct necessary maintenance or replacements.

Control circuit inspection: Examine control components and sensors within the circuit to ensure secure connections, stable voltage, and rectify any potential short circuits or open circuits.
