Mehrlochdüsen

Mehrlochdüsen, also known as multi-hole or multi-orifice nozzles, are devices designed to spray a liquid through multiple small openings. These nozzles are distinguished from single-hole nozzles by their construction, which incorporates a plate or a series of channels with numerous perforations. The primary function of a Mehrlochdüse is to atomize a liquid stream into a finer spray pattern, increasing the surface area for evaporation or improved mixing with a gas.

The design of a Mehrlochdüse can vary significantly depending on its intended application. The number, size, shape, and arrangement of the holes are critical parameters that influence the spray characteristics, such as droplet size distribution, spray angle, and flow rate. Some Mehrlochdüsen are designed to produce a conical spray, while others may generate a flat fan or a more complex pattern. The pressure at which the liquid is forced through the nozzle also plays a crucial role in atomization.

Applications for Mehrlochdüsen are diverse. They are commonly found in industrial processes such as cooling, humidification, cleaning, and coating. In agricultural settings, they are used for spraying pesticides and fertilizers. In combustion systems, Mehrlochdüsen can be employed to improve fuel atomization and efficiency. The ability to generate fine droplets and control spray patterns makes them a versatile tool in many engineering fields. Their efficiency and effectiveness are directly related to the precise manufacturing of the multiple orifices.
