What are the types of air atomizing nozzles
Air atomizing nozzles are one of the types of industrial nozzles. They are also alternative and special types of industrial nozzles. Air atomizing nozzles have high cost and complicated processing procedures. The same product will vary greatly due to different processing effects. This is also At present, there is chaos in the air atomizing nozzle industry, and the trend of professional development will improve this chaos in the near future. The air atomizing nozzle is also called two-fluid atomizing nozzle. The nozzle is divided into a body and a cap. The body of the body is mainly divided into the following 6 types according to different working conditions. The air atomizing nozzle is automatically controlled. Needle air atomizing nozzle, air atomizing nozzle with flow regulating valve, body-connected air atomizing nozzle, mini air atomizing nozzle, ultrasonic air atomizing nozzle. Liquid caps are divided into gas cap and air cap The spray forms of air atomizing nozzles are divided into fan spray and solid spray, 1 / 4SUC13A SUC13 SUNC13 SUC14 SUC11 SUC12A, etc.
Air atomizing nozzle The principle of air atomizing nozzle: The atomizing nozzle uses the friction of air and liquid to produce a very uniform and fine atomizing effect. The average atomizing particle diameter reaches 50 microns and below.
The structure of atomization is divided into pressure atomization and siphon atomization. The spray device has two modes: internal mixing type and external mixing type.
Internally mixed atomized gas liquid is mixed and atomized inside the air cap and liquid cap. The principle of atomization is air rupture and impact. The atomization effect is ideal, and it is not suitable for liquids with viscosity.
After the externally mixed atomized gas liquid is sprayed out of the nozzle hole, the liquid is frictionally atomized by high-speed airflow. The principle of atomization is the tangential stress generated by friction, and the atomization effect is general. Suitable for comparing liquids with viscosity.
Pressure atomization system: liquid on-off valve, liquid filter, hydraulic regulator and pressure gauge, nozzle, air regulator and pressure gauge, air filter, air on-off valve, pressure atomization system water requires a certain pressure, atomization effect Ideally, it is recommended for common and common atomization methods.
Siphon atomizing system: liquid container, siphon height, siphon tube, atomizing nozzle, air regulator and pressure gauge, air filter, air switching valve, air inlet. Siphon atomization sucks water by the negative air pressure formed by high-speed airflow, and the atomization effect is general.
