Decanter centrifuge is a settlement device. It has characterizes of compact, continuous operation, stable operation, adaptability, large capacity, easy maintenance and so on. It is widely used in chemical industry, light industry, pharmaceutical, food, environmental protection and other industries. To ensure stable operation of the decanter centrifuge for long-period, we must do routine maintenance work to the decanter centrifuge.
Centrifuge maintenance methods
Firstly, it is important to wash the drum regularly in order to reduce vibration of the decanter centrifuge when we take the idea of maintaining equipment into consideration. It will always deal with viscous solid-liquid mixture. As a result, a long-running of the decanter centrifuge will make drum and the wall of spiral attached thick sediment. If we do not rinse it clear, the balance rotate of the drum will be destructed due to the uneven force. Thereby, the decanter centrifuge will vibrate, which is very damaging. Rinse interval due to the nature of materials. Generally, sludge washed once a month is appropriate.
Secondly, in the production run, if the supernatant after sludge dewatering contains many solids, it is likely to cause the supernatant reflux tube blockage. This will result in decreased rates of dewatered sludge solids and the centrifugal pump will therefore vibrate. Therefore, according to the actual operating conditions, we must clean the supernatant reflux tube periodically.
Finally, a routine periodic inspection is essential in the management and maintenance of equipment. Daily maintenance: use the oil to refuel bearings of the decanter centrifuge drum to ensure lubrication.
Biweekly maintenance: clean the supernatant tube and check the flocculants dosing device.
Every 20 days to maintain: grease spindle bearings with grease gun. By maintaining centrifuge according to the above-described, we can keep the equipment in good operating condition.
In short, maintaining the decanter centrifuge has a great significance to ensure its long-term and stable operation. According to the characteristics of the operation, we must focus on doing the cleaning, lubrication and other work.
