Oilfield Drilling Mud System SS304 Screw Conveyor Horizontal Decanter Centrifuge
Horizontal spiral discharge sedimentation centrifuge (referred to as decanter centrifuge) is an effective separation equipment which use centrifugal acceleration generated by high-speed rotation into the acceleration of gravity to shorten thousands of times of the settlement time of solid particles than in the gravity field. The solid particles are discharged from the drum through the screw conveyor continuously and without interruption.
LW serial centrifuge has 3 control models of variable frequency and fixed frequency and Fully hydraulic type, and has abovementioned various centrifuges devoted for ocean drilling platforms.

The work frequency-driven centrifuge can change its speed through pulley and belt change, and the variable frequency centrifuge can realize infinite speed variation in a large scope and its control cabinet can directly display the parameters of work rev., work current and torque.
The engine may be suitable for power grids of 50Hz and 60Hz.
The roller and helix stowing tool, as the major components of the
centrifuge are designed independently by the company, and are made
of stainless steel (American Steel No.: 304). All the welding lines
are inspected and treated with certificate of conformity or record.
And the gyrator will have the resistance to wearing and erosion,
and the roller shield, segregation box, main transmission shield
and auxiliary transmission shield are all made of stainless steel.
The helix vanes are made through bead welding, spray welding and
modules to ensure the resistance of the centrifuge to wearing and
erosion, greatly improving its service life.It is equipped with
dual overload protective devices for machinery and electric
appliance for safe operation.
And it is equipped with the vertical or horizontal fluid-supplying
pump designed and produced by the company, with the tools and
reserves for equipment use and routine maintenance, with Chinese
and English Users Manual and block diagram and explosion diagram,
for users to choose the appropriate model, delivery, operation and
maintenance.
The maximum speed reaches 4000 rpm. Its fine seperation, advanced quality and technology have reached the international level.
LW serial Decanter centrifuge has been granted 7 patents including a flow controller for adjusting and controlling the feed quantity of the centrifuge (ZL200720079860.4) and a main bearing seat of the centrifuge used for drilling fluid-solid-phase control system (ZL200720080219.2)
