Decanter Centrifuge is Solids Control Industry

Decanter Centrifuge's usage in solids control industry

Since the lats 1980s, Decanter centrifuge has been widely used in the national oil industry(especially in deep wells and horizontal wells ). It is the dispensable solids control equipment. Decanter centrifuge includes spiral subsidence type, sieve water type, hydraulic turbine type and so on. In the oil and gas drilling industry, the most commonly used is Horizontal spiral sedimentation type centrifuges. And this horizontal decanter centrifuge also has low speed, middle speed and high speed.

Decanter Centrifuge's Structure: Main motor, Back drive motor,Hydraulic couplings, Drum bowl, Differential mechanism and Feeding pump etc.

The main motor drives the roller by driving the pulley on the roller through the belt wheel on the hydraulic coupling. The drum bowl is supported on two bearings. In the drum bowl, there is a screw propeller, the screw propeller is supported on the middle of shaft of drum bowl.  The differential is installed on the bigger side of drum bowl, it is a planetary gear reduction mechanism structure. The output shaft of the differential connects with the propeller and then make the propeller spiral. The input shaft at the right end of the differential is equipped with a pulley, which is driven by the auxiliary pulley to provide the differential input speed.  

The Decanter Centrifuge's Drum bowl is installed in a stainless steel box. The stainless box has two cabins, the left cabin collects the discharged fluid of centrifuge, and the right cabin collect the discharged solids from centrifuges.
