What equipment utilizes the principle of the Archimedes screw?

The Archimedes screw is a device historically used for raising water. It operates on the principle of converting rotational motion into linear motion, effectively lifting water from a lower elevation to a higher elevation. This is achieved through a helical screw that is enclosed within a cylinder; when the screw is turned, water is trapped in the spaces between the screw's helix and lifted upward.

Water pumps, specifically those designed to operate based on the Archimedes screw principle, utilize this mechanism to efficiently move water, especially in irrigation and drainage applications. The design provides advantages in moving large volumes of water with relatively low energy input, making it effective in various practical applications.

In contrast, heat exchangers, compressors, and fans operate on very different principles that involve heat transfer, gas compression, and airflow, respectively, none of which align with the specific operational mechanics of the Archimedes screw. This distinction underscores why water pumps are directly connected to the Archimedes screw principle.
