Szkrúszivattyú

Szkrúszivattyú refers to a screw pump, a type of positive displacement pump. It typically consists of one or more screws that rotate within a housing, creating cavities that move fluid from the inlet to the outlet. As the screws turn, the fluid is trapped in these cavities and propelled forward. This mechanism allows for a continuous and relatively pulsation-free flow.

Screw pumps are known for their ability to handle a wide range of viscosities, from low-viscosity liquids to highly viscous sludges and pastes. They are often used in applications where gentle handling of the fluid is important, as the pumping action is less turbulent compared to some other pump types. This makes them suitable for pumping materials like oil, grease, food products, and sewage.

The design of screw pumps can vary. Single screw pumps, also known as Archimedes screws, are common, as are twin-screw and three-screw configurations. The number and type of screws, along with their pitch and diameter, are designed to match the specific application requirements and the properties of the fluid being pumped. The materials used in construction also depend on the fluid's corrosiveness and temperature. Due to their robust design, screw pumps are often employed in industrial settings for tasks such as oil transfer, chemical processing, and waste management.
