Problems solved by technology
[0002] In the field of biological extraction, the extractor is the core equipment of the production process. The stability of its speed directly affects the extraction effect of the material. Due to its technological characteristics, the transmission speed of the equipment is slow and the power is sufficient. The traditional power comes from the motor driving the gear. The huge reduction ratio results in a relatively large design of the reduction gear, which takes up a lot of space and is inconvenient to maintain; the hydraulic motor is an executive component of the hydraulic system, which converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy of its output shaft (torque and Speed), its small footprint, low cost, and easy maintenance are its characteristics
[0003] At present, the hydraulic motor mainly relies on the mechanical structure in controlling the speed stability. The mechanical structure is relatively complicated, which is inconvenient to maintain and the maintenance cost is high; the hydraulic motor is used in combination with the extractor, which requires high speed regulation stability of the extractor. There is a good way to solve this problem
