Szívószivattyúk

Szívószivattyúk, also known as aspirators or suction pumps, are devices used to draw fluids or gases from one location to another. They are commonly employed in medical settings for procedures like wound suction, pharyngeal suction, and surgical aspiration. In laboratories, they are used for various tasks such as liquid transfer, filtration, and vacuum creation. Industrial applications include dewatering, chemical transfer, and pneumatic conveying.

There are several types of szívószivattyúk. Mechanical pumps, such as piston, diaphragm, or rotary vane pumps, utilize moving parts to create a pressure difference that draws fluid. Venturi pumps, a type of ejector pump, use a high-velocity fluid stream to create a low-pressure area, thereby drawing in the desired substance. Another common type is the water jet aspirator, which uses a stream of water to create suction, often used in laboratories where electricity may not be readily available.

The selection of a szívószivattyú depends on factors like the type and viscosity of the fluid being moved, the required flow rate, the pressure differential needed, and the operating environment. Medical aspirators are designed for sterility and precise control, while industrial pumps prioritize durability and high volume transfer. Safety features, such as overflow protection and antibacterial filters, are crucial in many applications, particularly in healthcare. The maintenance of these devices is also important to ensure their reliable and effective operation.
