The development of centrifugal- solid control

Now, abroad strengthen the research of the throughput and the speed of the centrifugal, increase the separation factors of the centrifugal, the most of the material of the centrifugal use the stainless steel, increase the corrosive. in order to increase the throughput of the centrifugal, improve the separation factors, a lot of details are amended and innovated.

The sand removing effect of many domestic centrifugal, because the separation factors is small, the separation of many foreign manufacturing is with in500-1000, it is appropriate for fresh water drilling fluid, overall vibration of the centrifugal is big, there are two main reasons;

1 The solid phase in the drum is not washed, have a part of residual sediment, destroyed the balance.

2 The bearing is abraded, the revolve of the drum is unbalance, the throughput of the centrifugal can’t reach the design requirements, the life time is lower recognition of the manufacture.

From the view of the reaction, we need a kind of centrifugal with large displacement, frequency control and speed regulation, so it can aggravate the drilling fluid and dispose the not aggravate drilling fluid. This kind of centrifugal is called all-around centrifugal, the whole system is frequency control and speed regulation, the rotation of speed can be regulated, the most high speed is above 3000r/min, as a high speed centrifugal , the separation factors F1 can reach 3050, as the mass flow centrifugal, the biggest through put is 100m3/h.

DCLW horizontal type helical-conveyer centrifuge is a mechine to separate the soild particles and liquid or separate the liquid and mixture mixed in the liquid by centrifugal force. The main function of centrifuge is to separate the liquid and solid particles in the suspension, or to separate the two kind of different liquid with different density which can not dissolve in each other in the emulsion. And also, can be used to remove the liquid from the mixture of liquid and solid. Some sedimentation centrifuge also can classificate the solid particles in the fluid with different density or granularity by identify the different sedimentation velocities.

DCLW horizontal type helical-conveyer centrifuge is special for theseparation of liquid and solid in oil drilling fluid, can finish the percedure of feeding, centrifuge sedimentation, unloading when it is fully operated. The main function is to recover the barite, clean the small solid, decrease the quantity of solid in the fluid, control the density and viscosity of drilling fluid to guarantee a good performance of the fluid.

The centrifuge is widely used in chemical industry, oil mining, food industry, pharmacy, minerals, coal mining, water treatment and shipping.
