Hydrocyclonde desander and desilter manufacturer from China
Hydrocyclones is an important part of desanders and desilters. Hydrocyclones have a wide variety of applications in many industries, particularly in oilfield application processing. The hydrocyclone is a continuously operating classification device with no moving parts. It utilizes fluid pressure to cause rotational forces that accelerate the settling of particles according to their size, shape and density.
According to the size of the cone diameter, they are divided into Desander and Desilter. Usually the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation. We commonly used 5 “and 4″ cone to separate solid-phase particle size 15-47μm in the drilling fluid. Based on customer requirements and capacity, we can select groups of cone into Desilter. DC Desilter works very well with Solids control system other equipments.
Usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. We commonly used 8 “and 10″ cones desander to separate solid-phase particle size 47-76μm in the drilling fluids

If you do have interest or any question, please contact DC Solids Control to get more puzzles solved. DC will give you more professional solution through experienced solids control engineer proposal
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.

Mud agitator is an important part of the drilling-fluid solids controling system. Drilling fluids agitator can be installed on drilling fluid tank, with the impeller submerged into certain depth under fluid surface to stir the fluid directly. During this process, the drilling fluid can be mixed even, and the solid particles are eliminated. In this way, it can improve solid phase dispersion, and increase the viscosity and gel strength, thus to make drilling fluid keep accordant with the requirement, provide needful fluid for drilling process, and ensure the smooth going of drilling work.Drilling mud agitator is the same as mud agitator.
DC solid control provide vertical and horizontal mud agitator. Horizontal mud agitator is divided into coupling type and direct type agitator. If you need a horizontal mud agitator, we recommend you use a direct type agitator. drilling mud Agitator is an ideal device for stirring, mixing liquid and preventing the solid-phase precipitation in the mixture.
The classification of hydrocyclone used for solid control system
Hydrocyclone is divided into drilling fluid desander, desilter and miniature swirler according different diameter.
The drilling fluid desander: The diameter is 150-300mm swiler is called drilling fluid desander. The throughput of desnader is exceed 20-120m3/h in the pressure of 0.2MPa. In the normal condition of drilling fluid desander can eliminate 95% is bigger than 74um drilling cuttings and 50% is bigger than 30um drilling cuttings. When choose drilling fluid desander, the throughput should be 5 times of maximum discharge.
The desilter: The diameter is 100-150mm swire is called desilter. When the input pressure is 0.2Mpa, the throughput can’t be less than 10-15m3/h. The normal working sate of drilling fluid desander can eliminate 95% bigger than 40um
drilling cuttings and 50% bigger than 15um drilling cuttings. The licensing throughput of desilter should be 1.25-1.5times of the maximum displacement.
We should add the right amount water in swire, decreasing drilling fluid density and viscosity and increasing the separation efficiency of swire.
Design hydrocyclone must base the minimum liquid loss provide the maximal solid phase eliminating efficiency. And it accords to well field physical truth, installation the appropriate number hydrocyclones to increase the treating capacity to meet the requirements of all drilling fluid performance in the whole drilling system.

Checking and installation of the drilling fluid shale shaker
The maintenance of shale shaker is easy, but has some stoppages and need know which common stoppages of shale shaker’s and how to solve it.
1. The rotation of drilling fluid motor is slow and bearing is fever.
The condition shows that the daily maintenance is bad, the bearing lack lubrication grease. If the new lubrication grease, the oil grease must have problem or adding too full, the inferior oil make the bearing is blocking and labyrinth seal is blocking stuff, so the quality of lubrication grease is very important.
2. Screening quality of shale shaker is not good
The reason is shale shaker operation is not reasonable may block shaker screen holes, the fine particles of screen material is increase and the moisture is increase make the material layer is too thick. Maybe the two sides of shale shaker pull not tight, if the eccentricity is vibrating, the belt drag don’t have strength, the belt is too loose, after this problems are disposed may have a retrograde rotation to improve screening quality.
3. The beam of shale shaker screen straining box is breakage
If the strength of screen box is not enough, the crosswise horizontal can’t find may cause the beam is breakage. If it still operation make the material flow is unusual. May be the operation is not reasonable. The material flow of shale shaker screen is unusual, one is the screen box strength is not enough exist critical frequency, attachment bolt has already shake loose even all shaker loose. The other is screen box crosswise horizontal can’t find right. We should find the faults in supporing seat of supporting spring or the spring, we should replace the spring or change the supporting seat size.
4. Shale shaker can’t start or the amplitude is too small
We should check the electric whether have accumulate, if it arouse we should eliminate the accretion on the shale shaker. We also check the coupling bolt in the exciter whether has drop, the lubrication whether change into ropiness, we should clean and check the exciter and adjust the eccentric shaft aggravating lump or the place of vice eccentric.
