GN Solids Control LTD and GN Solids America LLC’s VFD (variable speed drive) decanter centrifuge it allows oil well drilling service contractors or drilling mud service contractor company to perform the barite recovery, fine/ ultra fine solids filtrations and water-removal centrifuge. GN Solids Control LTD has the decanter centrifuge from 9 inch bowl to 22 inch bowl available for different solids-removal applications. GN Solid Control’s decanter centrifuge bowl length and diameter ratio is over 3 times and it gives the best result for the drilling fluids cleaning.
Purposely to make drilling fluid decanter centrifuge parameter to perform adjustment according to the drilling stratum, depth of the oil well and drilling technology evolved through times, the development of the variable-control speed and the closed-looped solids control system which basic on the main electric current to be as sending the control signal.
The oil-field application shows that drilling fluid decanter centrifuge matched frequency control speed closed-loop control system can use the different drilling fluid viscosity and density according to technology used and oil field’s physical condition.
Using decanter centrifuge main electric current signal, it automatic adjust the feeding pump displacement and high speed centrifuge actual parameter to realize drilling fluid centrifuge closed-loop control, ensure the de-slugging quantity and decanter centrifuge handing capacity always be in the condition at the fullest.
Drilling fluid decanter centrifuge frequency control closed-loop control system parameter can be automatic adjustment and realize self-awareness, also can efficiency avoid decanter centrifuge overload the fluid feeding and blocking. It can improve the reliability of centrifuge operation; reduce the uncertain operation surprise because of sudden failure.
By using frequency control speed closed-loop centrifuge can automatic and manual adjust decanter centrifuge’s rotary speed, make it can be as the middle speed centrifuge(1000-2000 rpm), also can as the high speed centrifuge( 2000-3000 rpm) to achieve efficiency control drilling fluid solid phase content and improve drilling fluid solid control condition.
