Performance indicators of Decanter Centrifuge

The working principle of the Decanter Centrifuge is that the drum and the spiral rotate in the same direction at a certain differential speed, and the heavier solid phase is deposited on the drum wall and discharged out of the machine, while the lighter liquid phase forms an inner liquid ring, which continuously overflows the drum from the overflow port at the large end of the drum, thereby completing the solid-liquid separation.
 
The Decanter Centrifuge can continuously feed, separate, wash and unload at full speed. It is suitable for separating suspensions containing solid phase particles greater than 0.005mm and a concentration range of 2-40%. It is widely used in drilling solid control systems, industrial production, pharmaceuticals, environmental protection and other industries.
 
Choosing a suitable Decanter Centrifuge can not only solve production problems and improve work efficiency, but also avoid the occurrence of failures, save production costs, and reduce safety risks. In oil drilling and industrial production, choosing a suitable Decanter Centrifuge should mainly be considered from the following aspects.
 
The first is to distinguish the speed of the centrifuge. Generally, the speed of the Decanter Centrifuge should be above 3000 rpm. The higher the speed, the higher the separation factor of the centrifuge, and the better the separation effect.
 
Secondly, the material of the centrifuge should be considered. Different application scenarios have different requirements for the performance indicators of wear resistance and corrosion resistance of the centrifuge. If only from the perspective of service life, centrifuge equipment with relatively high wear resistance and corrosion resistance should be selected. The general minimum material of the Decanter Centrifuge is 316L or duplex stainless steel, and the abrasive elements must be made of ceramic synthetic materials.
 
The differential control of the centrifuge also has a great impact on the performance. Different differentials have different control accuracy, which will affect the service life and maintenance cost of the centrifuge. Generally, the higher the differential accuracy of the Decanter Centrifuge, the better its adaptability to the material, so it is advisable to choose equipment with high differential accuracy.
 
The aspect ratio of the Decanter Centrifuge is an important performance indicator. Generally, the larger the aspect ratio of the Decanter Centrifuge, the greater its processing capacity and the lower the moisture content.
 
The control system is the key to ensure the normal operation of the equipment, and it is also a performance indicator that needs to be focused on.
 
The energy consumption control of the Decanter Centrifuge is crucial to saving production costs. When choosing a centrifuge, you should choose equipment with relatively ideal energy consumption control.
 
Finally, the most important thing is to observe the processing and manufacturing process of the decanter centrifuge. The decanter centrifuge is a separation equipment that requires high-precision processing. Products produced by companies that do not have the ability to fine-process have a high maintenance rate and limited processing capacity, so they need to be carefully identified.
