The relationship between different spray angle and coverage of nozzles and the advantages and characteristics, precautions
There is a close relationship between the spray angle of the nozzle and the coverage area, in general, the smaller the spray angle of the nozzle, the smaller the coverage area, but the spray liquid is more concentrated and can form a stronger impact force. On the contrary, the larger the spray angle of the nozzle, the wider the coverage, but the liquid will be more dispersed and cannot form a strong impact force.
Some common nozzle spray angles and advantages are as follows:
15-30 degree spray angle nozzle: With a small spray angle and a strong impact force, it can be used for applications such as cleaning, flushing and decontamination.
45-65-80 degree spray angle nozzle: With a large spray angle and moderate impact force, it is suitable for cleaning and flushing applications with large coverage areas.
95-110 degree spray angle nozzle: With very large spray angle and weak impact force, it can be used for a wide range of coverage applications such as cleaning, flushing, and spray wetting.
When selecting a nozzle, note the following:
The nozzle spray angle and coverage should match the application.
Make sure the flow and pressure of the liquid is appropriate for the selected nozzle.
Pay attention to the choice of nozzle material, should choose the material that can withstand the liquid chemical composition.
Ensure that the nozzle is matched to equipment such as pipes or pumps to ensure continuity and consistency of liquid flow.
The flow rate is proportional to the spraying pressure:
The greater the spray pressure, the greater the flow rate.The flow rate is proportional to the spraying angle: the smaller the spraying Angle, the smaller the area swept by the nozzle, and the corresponding flow rate is smaller.
The spraying Angle is inversely proportional to the spraying pressure: the greater the spraying pressure, the smaller the resistance to the flow, and the smaller the deflection Angle of the flow.
In practical applications, the flow size, spraying Angle and spraying pressure of the nozzle need to be selected according to the specific spraying requirements and occasions.
Under normal circumstances, a smaller spraying Angle can improve the density of the droplets, making the spraying uniformity better, suitable for occasions where fine spraying is required. The larger spraying angle can cover a larger area, which is suitable for occasions where rapid spraying is required.
The spraying pressure needs to be selected according to the specific spraying distance and the viscosity of the liquid. At the same time, it is also necessary to pay attention to the corrosion resistance and material selection of the nozzle.
