Hydraulic driven speed adjusting centrifugal machine

The utility model discloses a hydraulic driven speed adjusting centrifugal machine, and belongs to the field of the petroleum drilling industry. The hydraulic driven speed adjusting centrifugal machine comprises a hydraulic pump which is driven by a motor, an inlet of the hydraulic pump is communicated with an oil tank, an outlet of the hydraulic pump is communicated with an inlet of a hydraulic motor, and an outlet of the hydraulic motor returns to the oil tank. A drive shaft of the hydraulic motor is connected with a roller through a drive device and a belt transmission gear sequentially, and the motor, the hydraulic pump and the hydraulic motor are fixed on a base. According to the hydraulic driven speed adjusting centrifugal machine, a hydraulic system drives the roller of the centrifugal machine to rotate, and the rotating speed of the roller can be adjusted, the functions of high rotating speed, large treatment amount and stable performance are achieved, and the demand for a slurry treatment technology
