Csigaszivattyúknál

Csigaszivattyúknál, more commonly known as Archimedes' screw pumps, are an ancient and effective method of moving water from a lower elevation to a higher one. The design consists of a helical screw, typically made of metal or plastic, that rotates within a stationary cylindrical tube or trough. As the screw turns, its flights trap and lift volumes of water along its inclined axis. The efficiency of the pump depends on factors such as the pitch and diameter of the screw, the speed of rotation, and the angle of inclination.

Historically, Archimedes' screw pumps were powered manually, often by humans or animals turning a crank. This made them suitable for tasks like irrigation in agricultural settings, draining low-lying areas, and supplying water to towns. Modern versions can be much larger and are frequently powered by electric motors or other mechanical means, allowing them to handle significantly greater volumes of water for industrial, municipal, and large-scale agricultural applications. Their simplicity, reliability, and ability to handle solids without damage make them a continued choice for many water-lifting needs. The operation is continuous, providing a steady flow rather than the intermittent bursts seen in some other pump types.
