How Does a Backpack Sprayer Work?
There are mainly two types of backpack sprayers, one is a manual sprayer, and the other is a motorized one. Manual sprayers are best at spot treatment and combatting invasive pestilence. In contrast, motorized functions the same way, but it is more suitable to be used in large swathes of land.
Even though there aren’t any particular advantage nor disadvantage to using any of them, but they still got their differences. For a start, motorized varieties tend to be expensive, require extra maintenance, and have more weight than manual sprayers.
The next step is to consider choosing a diaphragm pump of the piston. Pistons help to pump powerful pressure as much as 90psi to dispense the liquid. Their swaying motion makes it very distinct and easy to differentiate.
Alternatively, a diaphragm pump also acts similarly in regard to the pressure in the tank. However, the biggest difference between these two is that diaphragm variety tends to be more powerful. They are best at handling harsher chemicals, so making them more capable of dealing with a wide infestation.
These ones also have better pest control ability through the special particles they dispense, making the process more effective. Overall, they come at a higher price than piston varieties. So, before splashing all your money on the latest one with extra gadgets, weigh in your options and consider what you require.
What Is Spray-Pattern and Spray Quality?
If your backpack lacks nozzle, then the solution discharges in a singular stream. However, with the help of a nozzle, the outflow is transformed into minuscule droplets. Depending on the nozzle design, the droplets make shapes unique to the nozzle. This is what a spray pattern is.
Typical spray patterns include flood, full or hollow cone, and flat fan, including its even and prolonged varieties.
Whereas, spray quality concerns the size of droplets that dispenses out from the nozzle. The droplets can be fine, medium, or coarse. Normally, you would be able to tell the size of the droplets when you spray it on plants.
If you want to change the size, then you can adjust the nozzle and pressure to come to a preferred size. And if the droplets come out too fine, then they can easily shift, while coarser variety doesn’t spread evenly, nor does it travel far away.
In other words, you can simply call this process of adjustments: calibration.
