Introduction
The product with the help of the working cavity in a plurality offixed volume conveying unit periodic transformation to achieve the purpose of conveying fluid.The original motivation of mechanical energy through the pump directly into the conveying fluid pressure energy the pump flow rate depends only on the working chamber volume change value as well as its in unit time changes in frequency and (in theory) and discharge pressure independent;rotor pumps rely on the two synchronous reverse rotation of the rotor (rotor blade number is 2-8 in the process of rotation)in the entrance to generate suction(vacuum)two rotor rotor chamber is separated into several small spaces in is driven by the trans mission shaft are rotated in the opposite direction medium is conveyed to the discharge port.Thus poses a higher degree of vacuum and discharge pressure so move in circles particularly suitable for high viscosity medium conveying.
