DCLW Decanter Centrifuges for oilfield applications
Decanter centrifuge is a important equipment in solid control system. It is widely used in drilling waste management system and oilfield mud circulation system.
Decanting centrifuge key part is screw conveyor and transmission. When centrifuge work, drilling fluid will flow into centrifuge through drilling fluid input. Then the roll bowl will increase speed and fluid will flow into centrifuge through one fixed input pipe. Since rolling bowl rotate at rather high speed.
Drilling mud decanter centrifuge are designed specifically to remove unwanted solids and fine particles from virtually all kinds of used drilling mud, including those based on water/synthetics and conventional oil-based drilling fluids.
Features of DCLW355 VFD Decanter Centrifuge:
1. Designed with high speed. The max speed can reach to 3400RPM
2. Made of selected material. The main body and main parts of the decanter centrifuge are made of selected stainless steel material. So, our centrifuge can resist rust or erosion.
3. Stainless steel with the tungsten carbide alloy protection can ensure a longer service life of the centrifuge
4. High quality and competitive price
5. Fast delivery and good package
DCLW Decanter Centrifuges for oilfield applications are often introduced to deal with drilling mud within active solids control system or waste effluent of drill cuttings. With middle speed decanter in operation, barite can be recovered and high speed decanter for the removal of undesired ultra fine solids.
Our purpose-built oilfield decanters are abrasion resistance, combine long life with capacity and performance, require less maintenance time and reduce down time. Top rated explosion proof motors with approvals of IEC Ex, ATEX, UL for option for hazardous area, wired with 460V / 60Hz, 380V / 50Hz.
LW355×1257-N drilling decanter centrifuge from China supplier
LW355×1257-N drilling fluid solid phase separation centrifuge is widely used in the drilling fluid solids control system of the petroleum industry to perform solid- liquid separation of drilling fluid, remove harmful fine solid particles such as cuttings in the mud, or recover recrystals Valuable and heavy materials such as stone can save mud cost.
The drive form of LW355×1257-N centrifuge is divided into power frequency drive and variable frequency drive. The drum speed of the power frequency drive is fixed, and the speed can only be changed by replacing the drive pulley; the variable frequency drive centrifuge can easily achieve a wide range of stepless speed regulation, and can display the speed, working current and other parameters.

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.

Our decanter centrifuge used for different Application:
Decanter centrifuge is widely used in industries as municipal and industrial waste water treatment, food processing, pharmaceuticals and chemicals, etc.
1. Decanter centrifuge solid phase dehydration: dehydration effect for processing materials of solid particles.
2. Decanter centrifuge particle size classification: used in the removal of material of large diameter solid particles.
3. Decanter centrifuge liquid clarification: used for removing solid particles in the suspension liquid are clarified.
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.
Drilling fluid centrifuge produced by DC Solid control
Drilling mud decanter centrifuge is the fourth stage equipments for a drilling mud system.Drilling mud cleaning first stage uses drilling fluids shale shaker ,then second stage uses desander,third desilter,(now drilling mud cleaner is widely used to replace desander,desilter).
The drilling mud decanter centrifuges can separate fine particles well,for separating 5～7μm particles in drilling mud,usually use medium speed decanter centrifuge,for less then 2μm,usually use high speed decanter centrifuges.
The drilling fluid centrifuge is mainly used for the separation of the suspension containing fine/ medium particles, and the solid particles of granular, crystal or fiber, especially for the separation of material whose viscosity is high, with fine fineness, it’s poisonous or inflammable. It is widely used in the industries of chemical, pharmaceutical, food, light industry and environment protection, etc.
Tangshan Dachuan Machinery Co., Ltd has a mature technology and complete product line, involving filtration, centrifugation, drying and crushing granulation and other products, the follow-up will be relying on its own technical strength, the introduction of more talents, and constantly develop new products, with more and better products and services to customers.
