Decanter centrifuge is a commonly used drilling mud processing equipment. The decanter centrifuge has the advantages of good separation performance, strong adaptability, continuous automatic operation, small exercise intensity, small footprint, and low maintenance cost, so it has won the recognition of customers.
Decanter centrifuges are more suitable for the harsh on-site working conditions of oil field drilling. The centrifuge uses the principle of centrifugal sedimentation to separate the drilling suspension. The suspension enters the drum from the feed pipe through the liquid outlet hole in the screw pusher, and the solid particles are pushed to the inner wall of the drum under the action of centrifugal force and pushed by the screw. The blades on the feeder are pushed to the slag discharge port at the small end of the drum, and the liquid phase overflows through the overflow hole at the large end of the drum. Such continuous circulation, in order to achieve the purpose of continuous separation. Centrifuge is used in the drilling mud treatment process to work reliably and have a long life.
The screw propeller, the key component of the centrifuge, is made of thick steel plate. The thickness of the wear-resistant layer on the surface is twice as thick as before, and the surface is sprayed with tungsten carbide. Ensure the ultra-long life of the centrifuge. The main bearing adopts imported high-quality bearings, and the differential adopts high-precision hardened gear transmission. The use of a decanter centrifuge to process drilling mud is based on the characteristics of petroleum drilling fluids. Special equipment for solid-liquid separation is designed to complete various processes such as feeding, centrifugal sedimentation, and unloading at full speed. It is mainly used to recover barite , To remove fine solids, reduce the solid content of the drilling fluid, control the density and viscosity of the drilling fluid, ensure the performance of the drilling fluid, and play an important role in rapid drilling.
