When a centrifugal pumps impeller rotates in the inverse direction, the flow of fluid through the pump isn’t reversed. However, the pump’s efficiency will drop significantly and you’ll notice that the flow is hindered.
The Archimedes screw pump, also known as the Archimedean screw pump, is a simple yet effective device that has been used for centuries to lift water and other fluids. This ingenious invention is attributed to the ancient Greek mathematician and inventor Archimedes, who lived in the 3rd century BC. The design of the Archimedes screw pump has stood the test of time and is still used today in various applications.
In the modern world, Archimedes screw pumps are widely used in wastewater treatment plants and for dewatering low-lying regions. Run in reverse, Archimedes screw turbines act as a new form of small hydroelectric powerplant that can be applied even in low head sites. See more
What is an Archimedes Screw?
The Archimedes screw consists of a screw - a helical surface surrounding a central cylindrical shaft - inside a hollow pipe. The screw is usually inclined at an angle, allowing it to rotate within the pipe. As the screw turns, it scoops up water or other fluids at the lower end and carries it to the higher end of the pipe. The fluid is then discharged at the top, using the principle of displacement.
What Does Archimedes Screw Do?
The primary function of the Archimedes screw pump is to lift water or other liquids from a lower level to a higher level. This makes it an essential tool for irrigation, drainage, and water supply systems. The screw pump is capable of handling a wide range of fluid viscosities and can be used in both industrial and agricultural settings.
Archimedes Screw Today
Even in modern times, the Archimedes screw pump remains a popular choice for various applications. Its simplicity, reliability, and efficiency make it a preferred option for lifting and transporting fluids. The screw pump is often used in wastewater treatment plants, aquaculture facilities, and renewable energy systems.
Screw Pump Archimedes
The design of the Archimedes screw pump allows for continuous and smooth operation, making it ideal for pumping large volumes of water over long distances. The screw pump can be powered by various means, including manual cranking, electric motors, or hydraulic systems. Its versatility and adaptability make it a versatile tool for various industries.
Archimedes Screw Used Today
One of the most common modern uses of the Archimedes screw pump is in wastewater treatment plants. The screw pump is used to lift sewage and other liquids from lower to higher levels, facilitating the treatment process. The gentle handling of the fluids by the screw pump helps prevent damage to the delicate microorganisms involved in the treatment process.
Diagram of Archimedes Screw
A typical diagram of an Archimedes screw pump shows the helical screw inside a pipe, with one end submerged in the fluid to be lifted. As the screw rotates, it creates a continuous flow of fluid along the length of the pipe, ultimately discharging it at the top. The design of the screw pump can vary depending on the specific application and requirements.
How Does Archimedes Screw Work?
The operation of the Archimedes screw pump is based on the principle of displacement. As the screw rotates, it traps a certain volume of fluid between the helical flights and the pipe wall. This trapped fluid is then carried upward as the screw turns, eventually reaching the top of the pipe. The continuous rotation of the screw ensures a steady flow of fluid, making it an efficient pumping mechanism.
The Archimedes' screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, is one of the earliest hydraulic machines named after Greek mathematician Archimedes who first described it around
Variable speed pumping is often used to optimize pump performance and minimize power use. Several types of variable-speed pumping equipment are available, including variable voltage and frequency drives, eddy current couplings, and mechanical variable . See more
