Sanitary Rotor Pump

Sanitary Rotor Pump

Operation Principle

• Rotor pump is also named 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 revolve in the sequence of a→b→c→d. When it revolves to position a, only housing I is filled with dedium; when it revolves to position b, housing B encloses part of the medium, when it goes to position c, housing Aencloses 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) transported continuously.

Transmission Of Rotor Pump

• Motor + fix velocity ratio speed reducer: this form is simple that the rotor speed is constant. So the flow is not adjustable. If frequency transformer is allocated, the speed adjustment can be achieved.
• Motor + mechanical friction type stepless speed variator: the speed variator of this speed variator is realized through manual adjustment. It is characterized by safe and reliable operation, as well as stepless adjustable flow. The flaw is that  it is non-automatic adjustment, which is different. The speed adjustment can be available only when it works.
• Frequency conversion motor + frequency converter: automatic adjustment of rotation speed can be realized in this way, and also stepless adjustment of flow can be realized. The advantage is a higher degree of automation and easy to operate. The drawback is the highter price and smaller low-speed torque.
