The pressure is converted into fluid kinetic energy to form a high-speed moving liquid column jet or liquid film jet, which meets the surrounding low-speed gas medium, and the liquid column or liquid film is broken under the action of crushing force and anti-crushing force, and then complete atomization. Mainly include direct current sprinklers, single centrifugal sprinklers, etc. Let's follow the editor of Cheapest water fog machine to take a look at the relevant knowledge of water mist nozzles!
1. DC nozzle
Under the action of the pressure difference, the spray liquid is sprayed through the nozzle and atomized under the action of fluid power and surface tension. The nozzle diameter of the direct current nozzle is generally 2 to 4 mm. If the diameter is too small, it is easy to be blocked, and the atomization effect is too poor if the diameter is too large. The jet cone angle is generally between 5° and 15°. The droplets are mainly distributed in a narrow range near the nozzle axis.

2. Single centrifugal nozzle
There are typically two types of centrifugal nozzles. One is a centrifugal nozzle with a tangential inlet. The liquid enters the centrifugal chamber through a tangential hole on the nozzle shell, and then is ejected from the orifice. One type is a centrifugal nozzle with a swirler. The liquid enters the spiral groove and moves downward while rotating. After leaving the nozzle, the liquid cluster is no longer restricted by the inner wall, and thus moves along the axis and tangential direction to form A tapered film, the so-called jet cone. The spray cone angle is generally 60°～120°.
The above is the editor of Cheapest water fog machine: a brief introduction to the relevant knowledge of water fog nozzles.
