atomizing nozzle is a device that can atomize liquid and suspend it uniformly in the air. Its working principle is through the internal pressure, the internal liquid is squeezed into the nozzle, the nozzle is placed inside a piece of iron, the high-speed flow of liquid impact on the iron sheet, after the rebound to form a diameter of 15-60 microns or so atomized particles, and through the nozzle outlet. So whether the atomizing nozzle is good depends on whether the effect of the nozzle atomization is in place, the effect of the atomization is not only affected by the nozzle unilaterally, there are many other reasons, you can improve the atomization effect through the following points.
1. Air pressure: Increase the relative velocity difference of the gas-liquid two phases to pressure power, so that the droplet is broken more finely under the action of larger aerodynamic force.
2. Increase the gas-liquid speed: increase the gas-liquid outlet speed to enhance the collision, so that the relative spray droplets can be further broken during the collision. The experiment found that if the droplet exit velocity is small, it will converge into large droplet, and the spray will cause humidity in the room. If the droplet exit velocity is large, the degree of atomization can be improved. However, this will reduce the relative degree of gas-liquid, so that the aerodynamic atomization droplets become worse.
3. Overall performance changes: the geometry and scale of the nozzle and mixing tube have a great impact on atomization performance. Therefore, in the design of the model, in addition to considering their influence on atomization separately, we should also consider the change of the overall performance after they are combined.
4. Water supply system: the relationship between the flow, pressure and nozzle geometry and structure shape of the spray water supply system can improve the atomization effect. In particular, the water pressure of the municipal water supply system has a greater impact on the atomization effect, and the higher the water pressure, the finer the water mist particles. However, high water pressure often brings some problems, such as high pressure on all parts of the water supply system, easy to fail, short life, especially the spray system is more vulnerable. In addition, when adjusting the water pressure, do not adjust the pressure of the machine to a large value, in order to avoid the machine can not reach the ideal pressure value because of the initial start of the machine and make the machine heat, reduce the service life of the main engine of the atomized water supply system.
If you want to achieve the atomization effect of the atomizing nozzle, first of all to buy a good quality high pressure washer, by adjusting the water pressure to improve the atomization effect, it is recommended to slowly increase the pressure value, high quality high pressure washer atomization effect will make everyone satisfied.
