Professional Manufacturer of Sanitary Lobe Pump

Rotor pumps are also called colloid pumps, lobe pumps, three-lobe pumps, universal transfer pumps, etc., and rotor pumps are positive displacement pumps. It achieves the purpose of transporting fluid by means of the periodic conversion of multiple fixed-volume transport units in the working chamber. The mechanical energy of the prime mover is directly converted into the pressure energy of the conveying fluid by the pump. The flow rate of the pump depends only on the volume change value of the working chamber and its change frequency per unit time, and (theoretically) has nothing to do with the discharge pressure; the rotor pump is working In the process, a pair of synchronously rotating rotors is actually used to achieve the purpose of conveying materials.

The coupling is assembled as a whole to make the volume smaller (the length can be shortened by 100-250mm), reduce the footprint, compact structure, stainless steel outsourcing, mirror polishing, beautiful appearance, high-grade, and avoid the peeling of the original paint. Performance optimization: the use of the coupling as a whole is assembled to reduce the power consumption of the elastic coupling, noise and wear replacement to improve work efficiency, and obtain the highest efficiency, the smallest internal sliding and a longer service life.

The rotor pump relies on two synchronous and counter-rotating rotors (the number of teeth is 2-4) to generate suction (vacuum) at the inlet during the rotation, thereby sucking in the material to be transported. The two rotors divide the rotor chamber into several small spaces and run in the order of a→b→c→d. When running to position a, only chamber I is filled with medium; when reaching position b, part of the medium is closed in chamber B; when reaching position C, chamber A is also closed with medium; when reaching position d, chamber A and chamber Ⅱ The chambers are connected, and the medium is delivered to the outlet. In this way, the medium (material) is continuously transported out.
