Cam rotor pump

Rotor pump is also named rotary lobe epump,

 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 revolves to position a,only housing I is filled with medium;

when it revolves 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 II are interlinked and the medium is transported to the outlet.

As this process is repeated,medium(material)is transpor-ted continuously
