Mechanical Engineering

if you really need help, then tell us in more detail what this help should be. Do you need to send a pump calculation, a pump model, or suggest literature on the calculation and design of the pump?

I need to design an Archimedes Screw Pump which has an inverse threads in a solid shell. I have have to come up with all the parameters of Archimedes screw pump which are Diameter of the screw, Diameter of the tube, Wall thickness of the tube, The length of the screw, Angle of inclination, Speed of the screw pump and the flow rate of the screw pump. The length of the screw must not be longer than 1 meter.

I also need to come up with the Pitch between the screw thread/blades. Because the current screw pumps have been having failure due to Thermal Expansion, Tube Cracking and Bottom bearing.

what you need is called a screw pump in modern technology. Have you been looking for a method for calculating a screw pump?

Yes a modern Archimedes screw pump, Yes I am looking for a method to calculate all screw pump parameters.

maybe it will be better

Thanks Tim but this journal is for Twin Screw Pump not an Archimedean Screw Pump.

Here is the info of what I need to design.

Outer shell tube design

               Support bearings on outer shell

               Approximate dimensions 8” pipe, 1m long (variable)

               Material: steel or PVC

               Hand driven initial but drive to be designed as well.
