Important part of oilfield drilling mud decanter centrifuge - drum Nov 12, 2018

In the structural composition of the oilfield drilling mud decanter centrifuge as an important component - the drum can be designed in different forms, such as cylindrical; conical; cone combination. In comparison, the cylindrical shape facilitates the clarification of the liquid phase; the conical shape facilitates the dehydration of the solid phase; and the combination of the cone and the cone has both advantages.


In the process of designing the structure of the oilfield drilling mud sedimentation centrifuge, the length to diameter ratio of the drum is usually selected from 1 to 2 (or 1 to 1.5), and the cone angle of the cone is generally 10 to 11; Generally 5 ° ~ 18 °. The drum material is generally stainless steel, high strength stainless steel, titanium steel, and glass steel. The drum is integrally cast or welded.


In order to ensure the structural design requirements of the oilfield drilling mud decanter centrifuge, special attention should be paid to the parameter design requirements of the drum. The main structural parameters include: drum diameter, drum length, drum cone angle, overflow diameter, and slag outlet. diameter. These parameters directly affect the separation capacity, processing capacity and slag transfer capacity of the oilfield drilling mud sedimentation centrifuge.
