Separation and characteristics of drilling mud sedimentation centrifuge
Drilling mud sedimentation centrifuge is mainly for the characteristics of oil drilling fluid in the process of operation. It is mainly designed for solid-liquid separation equipment during operation. Drilling mud sedimentation centrifuge can complete feeding and centrifugation at full speed. Sedimentation, unloading and other processes are mainly used to recover barite, remove fine solids, reduce the solid content of drilling fluid, control the density and viscosity of drilling fluid, ensure the performance of drilling fluid and play an important role in rapid drilling.
The drilling mud sedimentation centrifuge mainly uses the principle of centrifugal sedimentation to separate the drilling suspension. During the operation, the suspension is effectively passed by the feeding pipe through the liquid outlet hole of the screw ejector into the rotating drum, and the centrifugal force acts. The lower solid phase particles are pushed toward the inner wall of the drum, pushed through the blades on the auger to the small end of the drum, and the liquid phase overflows through the overflow hole at the big end of the drum. This cycle continues to achieve continuous separation. The mud centrifuge belongs to the category of horizontal screw centrifuges, and is called the horizontal spiral sedimentation type mud centrifuge.
The drilling mud decanter centrifuge can use manual or mechanical method to discharge the sediment at the end of the separation. The solid particles will effectively follow the liquid flow during the process of sedimentation to the drum wall. Movement, when the feed amount is too large, the liquid flows to the overflow port, and the fine particles that have not settled to the drum wall are discharged to the drum with the separation liquid, so that the separation liquid is turbid.
