When many people use low-pressure atomizing nozzle, they will feel that the effect of atomization is not the same as expected. That's where the problem comes in. We are according to the instructions to install, how spray can not meet the requirements?
So what is the principle of low-pressure atomizing nozzle, and how is the spray effect of low-pressure atomizing nozzle?
Low pressure atomizing nozzle principle and spray effect
Low voltage micro spray nozzle has a unique internal vortex blade, low pressure spray nozzle principle only depend on the liquid pressure can jet out very small droplets, form fine spray effect, using liquid pressure can produce very small droplets and droplet ejecting the average particle diameter of only about 40 microns, minimum atomized particle size can be up to 25 microns, Low pressure micro atomizing nozzle spray effect, and air atomizing nozzle can be comparable.Low pressure atomizing nozzle spray effect is very good, and can be comparable to the air atomizing nozzle
The spray effect of low-pressure atomizing nozzle is not good. According to the principle of low-pressure atomizing nozzle, first of all, we should think about whether the liquid pressure of injection meets the requirements, and then whether the viscosity and surface tension of liquid will affect the atomization quality? When the liquid is compressed to the nozzle mouth through the interior of the low-pressure atomizing nozzle, the spray flow is transformed into spray flow, which depends on the Reynolds number of the fluid.
The spray effect of low-pressure atomizing nozzle is not good. We need to improve the pressure and surface tension
The principle of low-pressure atomizing nozzle is that if the viscosity of liquid is reduced, the swirl strength of liquid in the low-pressure atomizing nozzle is increased, the tangential force and radial force are increased, and the atomization effect will be much better. In the middle stage of atomization, surface tension plays a major role. When the surface tension is reduced, it is easier for the liquid to split through the surface tension. In the late atomization stage of the low-pressure atomizing nozzle, the viscous force, surface tension, inertia force and aerodynamics of the liquid rub against each other, making the droplets further split. The farther the nozzle goes, the better it atomizes.
The greater the tangential force and radial force, the better the effect will be
Therefore, in the hope that the principle of low-pressure atomizing nozzle to get the best atomization effect at the same time, understand the principle of low-pressure atomizing nozzle. We also need to test the filtrate body and viscosity, how its surface tension, pressure Settings and so on can do a good analysis and adjust it to achieve the best effect, then the use of low-pressure atomizing nozzle is very easy.
