Twin-screw pumps and rotor pumps are two common fluid conveying equipment, both of which use rotating parts to push liquid flow.
First, the twin-screw pump has a more complex structure than the rotor pump, and requires two intermeshing spiral blades to rotate relative to each other to start the pump. The rotor pump uses a set of inner and outer rotors to rotate relative to each other, so that the liquid in the gap is pushed to flow. Therefore, the twin-screw pump requires higher manufacturing skills and process levels when working, and the product cost is relatively high, but its operation stability and delivery flow are well guaranteed.
Second, the twin-screw pump has a stronger conveying capacity than the rotor pump. It has a strong conveying capacity advantage when conveying media with high viscosity, high temperature, easy frost, easy precipitation, solid particles and other high requirements. Although the rotor pump also performs well in conveying liquids, it will have certain restrictions when the medium viscosity is high.
In addition, the maintenance and operation management of the twin-screw pump are relatively complicated, and lubricating oil, seals, etc. need to be replaced regularly. However, its service life is also relatively long, and professional operators and maintenance personnel can provide it with full protection and maintenance services. The rotor pump is relatively simpler, and the maintenance and daily management costs are lower
