Choosing the Best Nozzles for Your Sprayer

29 January 2021

Many industries today maximise water trucks in carrying out numerous functions. One of these functions is dust control. With appropriate water trucks, construction and mining companies can easily eradicate dust so that the site will be free from health risks. Water trucks are also used in controlling and extinguishing the fire. These special types of trucks are likewise utilised in soil compaction, farming, and delivery of potable water. Some of these functions are possible thanks to the presence of spray units.

Spray units or sprayers are often attached on water trucks so they can be effectively used for the projection of substances. From pest control to spraying lawns, spray units become much more efficient whenever they are paired with suitable nozzles. Choosing the best nozzles for your sprayers allow you to convert the substances in your tank into droplets, regulate their flow, and disperse the spray without fail.

To select the best nozzles for your sprayer, here are some elements that you must consider.

Nozzle Spray Pattern

Nozzle spray patterns are normally dictated by the spray angle and the shape of the pattern. For a more direct and penetrating spray, one should opt for nozzles with narrow spray angles. Wide-angle nozzles, alternatively, can provide overlapping coverage. Nozzles used for agricultural or farming purposes have spray angle between 65 and 120 degrees, allowing them to effectively provide water to the site.

As with the shape of the spray pattern, there are three basic options that you can choose from. The flat fan has a spray angle of 65 degrees, while the hollow cone has a spray angle of 80 degrees. A full cone can effectively spray at an angle of 120 degrees, covering everything within that said angle.

Nozzle Size

Aside from the spray angle and the shape of the spray pattern, a specific nozzle can easily distribute water to a specific site if it has the correct size.

In selecting the correct nozzle size, you must identify your nozzle flow rate at gallons per minute (gpm). Finding the nozzle flow rate can be done by determining the application rate in gallons per acre (gpa), the efficient and safe ground speed in miles per hour (mph), and the spray width per nozzle (W). Multiplying all these elements and dividing the answer to 5,940 can get you your needed gpm.

Specific Applications

There are notable nozzle patterns that can work well for herbicide, fungicide, and insecticide applications. For broadcast spraying, spray units with extended range flat fan nozzles, drift guard flat fan nozzles, and turbo flood wide-angle nozzles can all work on the previously mentioned applications. As for band and directed spraying, spray units with even flat fan nozzles and hollow cone nozzles are great for herbicide, fungicide, and insecticide applications.
