A variant of the Archimedes' screw can also be found in some injection molding machines, die casting machines and extrusion of plastics, which employ a screw of decreasing pitch to compress and melt the material. Finally, it is also used in a specific type of positive displacement air compressor: the rotary-screw air compressor.
Jul 3, 2019 · Given an Archimedes screw pump (shown below) how would you go about calculating the torque required to operate it? I'm assuming a situation where you have to design for a given flow rate, Q (m^3/s) and the diameter, angle of incline and head are known. The fluid to be pumped is water.
Sep 6, 2020 · i want to know if an Archimedes screw pump is more eficent that a modern screw pump to elevete clean waters 4 meters i saw many modern screw pumps smaller and want to now about the efcency of ths two types.
Feb 29, 2024 · An Archimedes screw requires rotational power to turn it. A water wheel provides rotational power. In principle it should be possible to make it work. There are a few practicalities: Waterwheels and turbines work best when there is a height difference between the inflow and outflow. Just lowering a paddlewheel into a river won't generate much ...
Feb 1, 2016 · I can't imagine an Archimedes screw ( figure) being effective moving air/ gas. If you want to get work out of high pressure air , A reciprocal machine, ie a "steam" engine would be about the only effective mechanism.

Dec 14, 2018 · Currently, I am using a screw pump, which can pump up to the full length of 5-6m. But with some issues. The flow often stops, for which we had to reverse the motor few rotations and then run forward. But this operation is not acceptable. The materials flown out of the pump was heating up by 8-10 deg.C.
Jul 14, 2022 · $\begingroup$ Thanks. Not quite. When you have a couple (two opposing forces with an offset), the resultant 'turning moment' is the same irrespective of your selected reference point (try it yourself by sketching it out - test moment around a point in between the forces and for a point somewhere remote from both forces).
May 26, 2019 · I have two no of motors connected in parallel of 7.5 kw max current capacity 30Amps. The load is about 18Ton is the motor sufficient to lift this load. The mechanical arrangement of screw jack system. The current now taken by motor is as such, Up movement: 37amps initial current and normal 33Amps.
