OPERATION PRINCIPLE
Rotor pump is also named rotary lobe pump, three-lobe pump, sole pump, etc. When the 2 simultaneous reverse rotating rotors（ with 2-4
gears）revolve, it produces suction force at the inlet（vacuum）， which intakes the material delivered. The 2 rotors divide the rotor housing into many smaller parts and revo- Ive in the sequence of a→b→c→ d When it revoles to position a, only housing I is filled with medium； when it revoles to position b, housing B encloses part of the medium, when it goes to position c, housing A encloses medium, and finally it goes to position d, then housing A, B and ll are interlinked and the medium is trans to the outlet. As this process is repeated, medium（materialis transpor-ted continuously.
