The right operation of drilling fluid centrifuge
Using centrifuge dispose drilling fluid, is using proper, the economic benefit is very considerable, such as it can decrease the cost of drilling fluid allocation, transportation and decrease the pressure difference and jamming drilling.
How to use proper
When use not water-based to drill, the viscosity of liquid phase is hypersensitive to temperature, but viscosity is the one of most important factor of effecting sedimentation, the high viscosity drilling fluid decrease the centrifugal rate of centrifuge, so to oil based drilling fluid, the viscosity is more high, we often use heating methods to decrease viscosity.
Correctly use centrifuge
When centrifuge is used with other solid control equipments, we must monitor the using of centrifuge. We should check volume and components of discharge fluid and ensure the separated solid phase particles volume of low and high density is simple. Sometimes we should analyse the particle size of feeding, bottom and overflow particles.

The main advantags of use decanter centrifuge in solid control system
Mud contains a certain fine particles and suspension fluid. The features of mud are decided by its material and local geological condition. If construct mud is misconduct can pollute environment. So the use technology of centrifuge can solve the problems, but the advantages of horizontal screw centrifuge process mud are very notable.
The capacity is big of single machine
Mud has output big and difficult to store, but the capacity is big of horizontal screw centrifuge single machine, horizontal screw centrifuge can process 60 cm3 mud per hour, it has the enough “measure” to eat the mud and digest it. So solve the problem that is the output is big and difficult to store. Compared with other mud processing equipment, horizontal screw centrifuge has the higher processing effect adapting bad field.
Centrifuge is a set at the construction field, but it can adapt the bad requirements.
It not fear expose to the weather; the change of field environment temperature is big, there is large dust in the air.
It not fear the overload impacting; the change of mud componential, the fluctuate of feeding flow, centrifuge has the enough power margin and the impeccable protection measures.
It not fear mud wear; the solid phase particles in the drum abrade every contacting part, but centrifuge has the enough wearing resistance ability. It not fears the electric interference; the big power motor frequently open and stop in the field, when all kinds of machine operate produce the electric arc led to electric source pressure has a big substantially fluctuate, but the centrifuge use the antiriot motor, so the conditions can’t appear. It not fears misoperation; the electric operation parts is less of horizontal screw centrifuge, the process is easy and easy to operate. Characteristics of differential mechanism.
The characteristics of differential mechanism:
Small speed ratio: the size of differential depends on the demanding sand, when the differential is too higher the time of remain is decrease make the moisture filter is increase, but the slip speed is too low will amplify the pushing momental of spiral,. In order to get rid of large desilting by centrifuge, differential speed must bigger than common sewage treatment centrifuge. The horizontal screw centrifuge is the small speed ratio.
Big torsion; the differential mechanism operate in the bad condition of high speed, heavy load and constantly bear impact cyclic loading, so demanding the resistance overload impact and torsional vibration isolation performance of differential is very good. The horizontal screw centrifuge can meet the requirement.

The optimum scowling speed is selected in each case according to solids load, required separation efficiency and required underflow density.
Actually, in drilling rig solids control system centrifuge is the most complicated one. It is rather difficult for operator get leagal operation, etc. However, in long term its important position is following shale shaker subsequently.
Key benefit of oilfield centrifuge from DC Mud equipment company
An oilfield centrifuge is one of solid control equipment which has a capability to remove solid which is larger than 10 micron.The oilfield centrifuges have limitations on feed rate, solid discharge, power of motor, etc. Therefore, it cannot handle the entire solid in the mud.
The best way is to place shale shakers and/or hydrocyclones upstream of the centrifuges in order to remove large solid particles and let the centrifuges remove large portion of small particles which cannot be separated by shale shakers and hydrocyclones. By doing that, you will be able to effectively eliminate both large and small particles.

Complementary use of hydrocyclones and centrifuges
DC Machinery offers solutions for all of your Classification needs from hydrocyclones and centrifuges to classifiers and heavy media separation.
Hydrocyclones are related to centrifuges in that both are intended to separate heavies and lights by application of centrifugal force. The key difference is that hydrocyclones are passive separators capable of applying modest amounts of centrifugal force, whereas centrifuges are dynamic, spinning separators that are generally able to apply much more centrifugal force than hydrocyclones.
Another key difference between hydrocyclones and centrifuges is cost. Centrifuges are expensive precision rotating machines that often need sophisticated control, whereas hydrocyclones have no moving parts and usually no controls at all, so they are lower cost devices.
Hydrocyclones and centrifuges are complementary rather than competing devices. If gravity alone will settle a significant portion of your solids in a minute or two using a quick bottle test, you should investigate hydrocyclone separation. If settling takes much longer than this, then you may need a centrifuge or other separation method.
