CENTRIFUGES
DE-7200 VFD |
||
 |
The DE-7200 Variable Frequency Drive (VFD) centrifuge offers the high flexibility in system control, permitting it to handle a wide range of feed slurries. Its automatic startup and shutdown routines permit safe, consistent, unattended operation. Automatic load sensing and feed pump control facilitate automated performance optimization. The bowl can be operated at up to 3000 RPM, resulting in centrifugal acceleration of 2750 G’s. To accommodate low levels of agitation and rapid solids removal, the conveyor can operate at differential speeds ranging from 1 to 80 RPM. The DE-7200 drive system consists of two explosion-proof inverter-duty motors. A 150 HP motor drives the bowl, and a 60 HP motor operates the conveyor. |

DE-1000 VFD Smart Centrifuge
DE-1000 VFD Optional Control Cabinet |
The DE-1000 Variable Frequency Drive (VFD) centrifuge offers maximum flexibility in system control, ability to handle a wide range of feed slurries, and suitability for use in Class I, Division 1, Group D areas. A windows-based PC monitors and controls operation of the bowl and conveyor drive motors, as well as the feed pump. The control system is capable of both local and remote control. A user-friendly graphical interface provides the operator with current system status information, as well as concise operating screens. The PC provides the operator with critical machine status information. Electronic load sensing and feed pump control permit automatic optimization of feed rate, bowl speed, and differential conveyor speed. Direct readouts of RPM and torque are provided for the bowl and conveyor drive motors, and a GPM indication is provided for the feed pump. Bowl speed is variable from 0 to 4000 RPM for an internal acceleration of more than 3000 G’s, and conveyor speed is variable from 1 to 100 RPM. Its stainless steel bowl and hardened conveyor tiles ensure that the VFD centrifuge requires minimal maintenance. |

 |
Operating at bowl speeds from 0 to 3400 RPM, with internal centrifugal acceleration exceeding 2300 G’s, the DE-1000 Full Hydraulic Drive (FHD) centrifuge can process 20 pounds per gallon of weighted mud, as well as flocculated ultra-fine solids slurries. A self-contained hydraulic system supplies pressure to the hydraulic motors that drive the bowl and the differential conveyor that operates at 3 to 90 RPM. |

DE-1000 GBD |
||
 |
The DE-1000 Gearbox Drive (GBD) centrifuge operates at bowl speeds up to 4000 RPM and is driven by a 50 HP electric motor connected by a drive belt to a gearbox through a fluid coupling. A spring-loaded torque-out assembly with manual reset protects the gearbox and motor in case of overload. A drive belt transfers motion from the gearbox to the bowl assembly. Control is provided by starters installed within explosion-proof boxes. The start/stop buttons and manual switches are within easy reach of the operator. The GBD centrifuge is designed for minimal maintenance. It includes the same stainless steel bowl as the FHD and VFD centrifuges. |
