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. Read More

Q1: What are the standard operating procedures for starting, running, and stopping industrial centrifuges? 1. Pre-start: Check the condition of seals, bolts, screens, and bearings; ensure there are no obstructions; inspect the power supply, variable frequency drive (VFD), and lubrication system; and perform a no-load test run to ensure normal operation. 2. During operation: Start at low speed and gradually increase to operating speed (direct full-speed startup is strictly prohibited); feed material at a steady rate (overloading or uneven feeding is strictly prohibited); and monitor vibration, noise, and discharge status in real-time. 3. Shutdown: Stop feeding first and allow the material to separate and discharge completely before shutting down the machine (emergency stops with material inside are strictly prohibited); after shutdown, clean out residual material and take measures to protect the equipment from dust.

Centrifuges achieve solid-liquid, liquid-liquid, and three-phase separation through centrifugal force. In the chemical industry, horizontal decanter centrifuges are mainly used for wastewater treatment. In cases with oil content, disc centrifuges are more commonly employed. They are mainly used in the pre-treatment, intermediate treatment, and sludge processing stages and cannot be directly used as end-point compliance equipment. Read More
