Audited Supplier Working Principle
This machine operates based on the settling principle and is designed for the separation of solid and liquid phases in a suspension. The suspension enters the spiral pusher through the feed pipe, accelerates after passing through the accelerator, and then enters the drum. Under the influence of centrifugal force, the solid phase is thrown towards the inner wall of the drum. The spiral blades push the solid phase sediment through the slag discharge outlet. The lighter liquid phase is continuously clarified within the drum and flows towards the large end of the drum, exiting through the overflow outlet.
SENZ Oilfield decanter centrifuge is the main equipment of drilling fluid solids control system, mainly used for removing harmful fine particles from drilling fluid, controlling drilling fluid density and viscosity, and improving drilling fluid performance.
It can also be used to recover barite in the weighted drilling fluid, SENZ oilfield Decanting Centrifuge can used widely in the flied of oil drilling mud control, Drilling Waste Manegement, Sludge Dewatering, Dredge Dewatering etc.
We can provide OEM/ODM customized services, For example, we can provide medium-speed centrifuges to remove 5-7μm solid phases. If you need to remove 2-5μm fine solid phases in drilling fluids, you can choose SENZ high-speed centrifuges, and all operating systems can be integrated into the PLC to improve equipment automation and reduce human intervention, improve production efficiency and reduce labor cost investment.
VFD Variable Frequency Centrifuge
The SENZ VFD variable frequency centrifuge separates particles of 2 ~ 5 µm, and the barite recovery rate of LW355 can reach over 90%. This equipment is mainly used in applications where the mud density varies greatly and the working conditions are complex, and the operating parameters of the centrifuge need to be adjusted to achieve the desired treatment effect, such as shale gas wells, high temperature, and high-pressure wells.

Barite Recovery System
SENZ barite recovery system (BRE) is a kind of independent working system with a frequency conversion centrifuge as the core equipment, an integrated mud tank, centrifugal pump, agitator, electrical control system, and corresponding piping valves. The recovery rate of barite of the XBSY BRE system can reach more than 90%.
1.Equipped with high-speed VFD centrifuge, it can efficiently recover barite while effectively removing the fine and harmful solid phase.
2.Complete System Process - In addition to the recycling process, there are processes for mixing, cleaning, and conveying.
3. Highly integrated - All equipment and appliances are skid mounted design.
Oil-Based Drill Mud Treatment System
Senz oil-based drilling mud treatment system is mainly composed of a cutting dryer, centrifuge, screw conveyor, collection tank, shale shaker, and drilling fluid recovery equipment. After treatment, useful oil-based mud can be recovered, while the solid phase water content can be effectively reduced to achieve waste reduction and incineration energy saving.
1.Skid-mounted Unit - Convenient for lifting, transportation, and on-site placement.
2.Low Oil Content - The oil content of the treated drill cuttings is less than 8%, which is convenient for bagging and transportation.
3.Lower the Density of Liquid Phase - The density of the treated liquid phase can be reduced to 1.2g/cm³, much lower than the 1.35g/cm³ of ordinary oil-based drill cuttings treatment equipment, and can be directly returned to the mud circulation system for reuse.
Technical Advantage:
1. Industrial design
Whole machine set design follows concept of advanced industrial design,ensures stability,functionality and safety of whole machine.Also effectively absorbs shear force of dynamic load during operation.
2. Effectively ease resonance during rotating of bi-rotor
When centrifuge works,there is no obvious first-order and two-order resonance regions within designed speed range,meanwhile ,whole vibration intensity of bearing seat is definited within 2mm/s-4mm/s.All of this eliminates extra fatigue damage to components and assembly units from high frequency vibration during operation and sudden vibration when shut down.
3. Thoroughly eliminate phenomenon of liquid ring stalling
Phenomenon of liquid ring stalling happens during heavy duty boot or shutdown process of complete set machine,especially for LW550 and even larger models,It would makes bounce or wild shake,causes extra impact fatigue damage to main bearings,screw bearings and inner parts of rotary bowl.Fortunately ,our engineers have solved this problem thoroughly.
4. Unique technique adopt in main component work-blanks
The manufacturing methods of main component work-blanks are adopt centrifugal casting technique and overall mould-making forging technique,thoroughly avoid risks such as inter-granular corrosion and relaxation of residual stress release in welding joint.
5. Main bearing selection
We use origin bearings of international first-line brands
6. Constant temperature detection
All fashioning components and assembly units are detected in constant temperature condition,to make sure of actual processing quality meets the requirements of designed precision accuracy.
7. Inter-change ability
Whole machine physical design and processing technique adopted in critical position,ensure all assembly units and bowls of the same centrifuge model interchangeable.It is not only easy to maintain ,but also greatly improve the reliability and safety of equipment.
8. Simplyand safely in bearing disassemblement
One layer of oil film is injected into contact surfaces between bearing and work-piece by high-
pressure,during disassemblement bearing from the machine.which would fundamentally eliminate friction within different parts.As a result,it would reduce 90% of pulling force and lower the risk of damage to high-precision parts when disassemble bearing.
