I am a 4th chemical engineering student. I am haveing issues designing a suitable pump that will be able to handle an extremely fibrous substance, such as alginic acid. The slurry contains 80% fibre solid, 20% water and therefore will be extremely difficult to pump. However, I am wanting validate this reasoning through design. I have selected screw or gear pump as they can handle really low flowrates. I was wandering if someone could give me some guidance on how screw pumps operate, as they will be ideal as it won't affect the integrity of the substance being pumped. Can someone direct me towards where I could find design equations for screw or gear pumps?
I have identified this list below as being key specs on the pump, am I right? diameter, flowrate, head loss, back pressure , viscosity of fluid
Capacity of Screw Pump: Diameter of screw, Speed of screw, no. Of flights mounted on screw ,Angle of inclination ,motor speed ,
efficiency of gear pump: Fluid Density, Pressure rise ,Displacement Volume (Q) , Rotational speed (n) ,Driving torque (T), Efficiency
thanks in advance.
