1. What Characteristics Must Be Considered When Designing a Spray Nozzle? Typically, spray nozzles are designed to work effectively under different spraying conditions. It can be possible that more than one type of nozzle can meet the requirements of one application. Whether you need to create spray nozzles for agricultural, cosmetic applications, pharmaceutical, or other applications, there are key characteristics of sprays that play a great role in designing the right nozzle for spray equipment. Spray imaging characterization can help you determine each characteristic of spray and come up with the right fit for the intended application. So, today, we will discuss the characteristics of a spray that you must consider before designing a nozzle. 1.Spray Pattern Though you can spray surfaces with any spray pattern shape, results are largely dependent on the type of spray pattern used. If the surface you need to spray is fixed and doesn’t move, you may prefer a full cone nozzle as it can cover more area than other styles. However, for spatial applications where you don’t want to focus on a surface, you need specialized spray characteristics. In such cases, one can achieve desired results based on different factors like drop size and spray velocity. Different types of spray patterns include solid stream, hollow cone, full cone, flat spray, and multiple plume spray. 2.Nozzle Capacity The capacity that a nozzle can have varies with spray pressure. Typically, most spray nozzle manufacturers calculate nozzle capacity based on water. For this, one must remember that the specific gravity of a liquid can change the flow rate of liquid. Thus, it is something that you should not ignore.

2. 3.Spray Impact, Pressure, or Impingement Spray impact depends on two things. The first is spray pattern distribution and the second is the spray angle. If your application requires high impact, you should consider solid stream nozzles or narrow spray angle flat fan nozzles. When a nozzle is used for cleaning equipment, the impact or pressure of spray is referred to as impingement. In general, for all spray patterns, the unit impact of spray on a surface reduces as the distance from the spray nozzle increases. 4.Spray Angle and Coverage Area Depending on the distance from the orifice of the nozzle, the spray angle either diverges or converges with respect to the vertical axis. In general, the spray angle is believed to remain the same throughout the entire spray distance. Liquids with a higher viscosity than water form smaller spray angles or solid streams based on different factors like nozzle capacity, spray pressure, or viscosity. Liquids with a lower viscosity than water tend to form wider spray angles. Spray angles are crucial, especially in coating applications to avoid over-spraying, in combustion engines to prevent wetting of cylinder walls, and fire sprinklers to provide sufficient coverage. 5.Drop Size of Spray The drop size refers to the size of spray drops that form a spray pattern. The size of spray drops is not the same for all drops even within a given spray. You can describe drop sizes within a spray through the fineness of a spray or the diameter of a drop. If you are a nozzle manufacturer and need to create the perfect nozzle for a particular application, spray imaging characterization will help guide you throughout the process.
