Working principle of rotary pump

The rotary pump relies on two synchronously rotating rotors (with 2-4 teeth) to generate suction (vacuum degree) at the inlet during the rotation process, thereby sucking in the material to be conveyed. Two rotors divide the rotor chamber into several small spaces and operate in the order of a → b → c → d. When operating to position a, only chamber I is filled with medium; When reaching position b, a portion of the medium is enclosed in chamber B; When reaching position C, the medium is also enclosed in room A; When reaching position d, chamber A and chamber B are connected to chamber II, and the medium is transported to the discharge port. In this cycle, the medium (material) is continuously transported out.
