Industrial Centrifuge FAQ --Daily Operations

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.

Q2: Can the feed rate and rotational speed be adjusted arbitrarily during centrifuge operation?

No. Frequent or drastic adjustments to feed rate and rotational speed while the equipment is running stably are strictly prohibited. Excessive feed rates can cause material accumulation, uneven drum loading, and incomplete separation, leading to severe vibration. Sudden changes in speed can damage the VFD, bearings, and drive system, thereby reducing the equipment's service life. If parameter adjustments are necessary, make only small, incremental changes and observe the equipment's operating status.

Q3: Can production continue if slight vibration or abnormal noise occurs during operation?

Continuing operation is not recommended. Slight vibration and abnormal noise serve as early warning signs of equipment malfunction, often caused by uneven material loading, solid accumulation, bearing wear, or loose components. Continued operation exacerbates component wear and increases vibration amplitude; consequences range from reduced separation efficiency and higher energy consumption to major safety incidents—such as drum imbalance, component fracture, or equipment damage—requiring immediate shutdown and troubleshooting.
