Industrial Centrifuge FAQ --- Troubleshooting Common Faults

Q1: What causes poor separation performance (e.g., cloudy supernatant, high moisture content in the solid phase), and how can this be resolved ?

Key causes and solutions:

1. Rotational speed below setpoint (VFD fault or speed sensor failure): Inspect the electrical control system and calibrate speed parameters;

2. Filter screen/cloth clogged, damaged, or incorrectly selected: Clean or replace the filter medium and re-select based on material particle size;

3. Excessive or uneven feed rate: Reduce feed speed and maintain a steady flow;

4. Fluctuations in material properties (e.g., increased viscosity, finer particles): Increase rotational speed and/or extend separation time;

5. Imbalance due to material buildup on the inner drum wall: Shut down the machine and clear out residual material.

Q2: What causes the centrifuge to vibrate violently or the machine body to shake severely, and how should this be addressed?

Common causes:

1. Uneven material distribution or accumulation of solid residue inside the drum;

2. Bearing wear, aging, or lubrication failure;

3. Loose anchor bolts or improper leveling during installation;

4. Deformation of the drum or main shaft, or imbalance due to component wear;

5. Off-center loading or excessive fluctuations in material concentration.

Solutions: Immediately shut down the machine, clear residual material from the drum, tighten anchor bolts and re-level the equipment, replace worn bearings and replenish lubricant, inspect drive components, and optimize feed uniformity.
