The spray device of the air atomizing nozzle has two types: a pressure spray device and a siphon/gravity spray device. A pressure spray device is a spray of air and liquid that can be mixed internally and externally to produce a complete atomization, in which simply the liquid is delivered to the nozzle by pressure. The siphon/gravity transfer spray device is a liquid transfer through a siphon or gravity transfer. It is said that the liquid can be sucked through the transfer line into the air flow and atomized therein.
Each series of air atomizing nozzles is provided with a pressure spray device or a siphon spray device. Each spray unit provides a specific spray shape, flow and spray coverage. The spray unit can be replaced with one another in different nozzle series. Each spray device includes an air cap and a liquid cap.
Internal mixing characteristics: Liquid and air are mixed internally to produce a fully physicochemical spray. The liquid and gas flow are not independent, and changes in the air flow can also affect the flow. The internal mixing uses a pressure device that provides the following spray forms: ring spray, fan spray, deflecting fan spray, round spray, wide-angle round spray and oval spray.
External mixing characteristics: The liquid and air streams are mixed outside the nozzle. Air and liquid flow can be controlled separately. Effective spray high viscosity liquids and suspended abrasives. External mixing enables the use of pressure devices and siphon devices. A circular spray is sprayed using a siphon. A fan spray is sprayed using a pressure device.
