VFD Variable Frequency Centrifuge

The XBSY VFD variable frequency centrifuge separates particles of 2 ~ 5 µm, and the barite recovery rate of LW355 can reach over 90%. This equipment is mainly used in applications where the mud density varies greatly and the working conditions are complex, and the operating parameters of the centrifuge need to be adjusted to achieve the desired treatment effect, such as shale gas wells, high temperature, and high-pressure wells.

Features
  • Adopt a frequency converter to control the motor start and stop, and adjust the rotating speed of the drum and pusher.
  • Centrifuge speed, operating current, torque, and other parameters can be viewed in real-time.
  • The recovery rate of barite can reach over 90%.
  • It is widely used in complex working conditions such as shale gas wells and high-temperature and high-pressure wells.
