What is the maximum operating speed of the screw pump? What are the disadvantages of knoll screw pump?
2023-09-21 15:54:23
Depending on the fluid and its viscosity, screw pumps can operate at speeds ranging from 500 rpm to 3,600 rpm. The frequency converter can be used to change the shaft speed, allowing the user to control the flow as needed.
Disadvantages of knoll screw pump:
As with all engineering equipment, screw pumps have a design range that, if used outside of this range, will produce disappointing performance and/or shortened service life.
Having a long meshing screw makes this pump completely unsuitable for solid or abrasive media, except in some very special cases where screw pumps are really only suitable for fluids with at least some inherent lubricity.
• Screw pumps rely on precision clearance and have multiple rotating elements. This makes them more expensive to produce than centrifugal pumps.
• Their ability to generate high pressure can also be a problem! If there is any risk of a "valve off" situation, a pressure relief valve and/or pressure switch must be used to prevent a potentially dangerous situation in the pump that results in excessive discharge pressure.
• The mechanical design of screw pumps means that fewer material choices can exist compared to centrifugal pumps.
