Reasons that affect the effect of the spray nozzle

Under normal circumstances, the spray nozzle will only achieve the desired atomization effect when the standard pressure is reached. If the pressure is lower than the minimum required for the nozzle, the atomization effect will be discounted, and the pressure will also affect the nozzle. Flow rate, increasing the pressure without increasing the nozzle parameters can increase the flow rate of the nozzle. In general, a booster pump or the like can be used to increase the pressure of the liquid, and an air compressor or the like can be used to increase the pressure of the gas.

Spray angle

The spray angle refers to the angle at which the atomized liquid is dispersed. Even if it is the same spray nozzle, it can have a variety of spray angles to choose from, depending on customer needs, and at different pressures, the spray angle will also have Minor differences. Under normal circumstances, the larger the spray angle, the greater the coverage of the installation height and pressure.


The flow rate is mainly affected by the pore size and pressure of the orifice. Under normal circumstances, the larger the orifice diameter, the larger the flow rate; the same pressure, the greater the pressure, the flow will increase. In addition, the flow rate will also be affected by the spray medium. Under the same pore diameter and the same pressure, the flow rate will decrease as the viscosity of the medium increases.


The coverage of the spray nozzle is mainly restricted by the spray angle and the nozzle installation height. When the other parameters of the nozzle are fixed, the larger the spray angle of the nozzle, the wider the coverage; the higher the nozzle installation height, the wider the spray coverage.


 Due to the different temperature resistance of spray nozzles of different materials, the temperature mainly affects the choice of nozzle materials. The temperature of the liquid (spray medium) does not exceed the temperature resistance range of the nozzle itself, and does not affect the spray performance of the nozzle itself. However, since the temperature affects the viscosity and specific gravity of the liquid, the result of the spray will be slightly different.
