Ⅰ. Overview and Applications
The medium-speed series centrifuges produced by our company are of the sedimentation type. As a machine that uses centrifugal force for solid-liquid separation, they rely on centrifugal force generated by the centrifuge’s high-speed rotation to make high-density solids in drilling fluid settle and separate under centrifugal action. These centrifuges can separate solids larger than 5 μm, effectively solving the problem that cyclone devices cannot separate ultra-fine harmful solids, and thus serve as key solid control equipment on drilling platforms.
The medium-speed series centrifuges are mainly used to control the density and viscosity of drilling fluid, reduce the solid content in drilling fluid, remove harmful solids or recover barite, and perform secondary recovery and utilization of cyclone underflow. These functions ensure the excellent performance of drilling fluid and improve drilling speed. After treatment by the centrifuge, the drilling fluid not only has controlled density and viscosity, but also significantly reduced sand content—this reduces equipment wear, extends equipment service life, and delivers remarkable economic and social benefits.
With rational design, strong adaptability, large processing capacity, simple operation, and convenient maintenance, this centrifuge is suitable for the fifth-stage solid control treatment of mud and liquids to be processed in projects such as onshore and offshore oil and gas drilling, coalbed methane extraction, trenchless directional crossing, piling engineering, and waste sewage/mud treatment.
In the medium-speed series centrifuges produced by our company, cemented carbide blocks are inlaid on the conveyor blades to enhance the conveyor’s wear resistance. Additionally, all bearings in key parts are imported, which extends the service life of the entire machine.
