A sprayer is a device that is a fully integrated, mechanical system, composed of various parts and components that work together to achieve the desired effect, in that case; the projection of the spray fluid. This can be as simple as a hand sprayer attached to a bottle that is pumped and primed by a spring-lever, tube, and vacuum-pressure; or as complex as a 150-foot reach boom sprayer with a list of system components that work together to deliver the spray fluid.
1. A Sprayer, by definition, is a mechanical device, commonly called an "infusion pump," that processes the fluid into the required level of viscosity. With increasing horsepower, and greater effort applied, the liquid flows into the applicator, often over a controlled working orifice, until the desired viscosity is reached.
2. When designing a spray system, the size of the infuser pump and the length of the hose are both key factors in the overall system design. So, when deciding which system is best for the job, consider the pump size and length, and think about the required final spray volume.
3. Another important component of the system is the length of the nozzle or "comb" used to spray the fluid, also referred to as the nozzle's "legs.
Sprayers can be categorized in several ways based on the components used in the construction of the spray mechanism. These types of classification include gravity-driven, flywheel-driven, and pneumatically operated. A gravity-driven sprayer is the most commonly used sprayer type, and this classification is further divided into manual-type and automatic-type. Manual-type gravity-driven sprayers are usually operated by a manual pump with air pressure or hydraulic pressure, while automatic-type gravity-driven sprayers are usually controlled by a servo, pneumatic, or electric pump.
Whether they are gravity-driven or powered by electricity, the parts of a gravity-driven sprayer are meant to produce very high pressure.
In order to be effective, a spray system must be well designed and produced with consistent quality and finish, and have a consistent pressure to deliver fluid to the desired point. For example, if you plan to aerate or apply pesticides, you will need to know that you need a variety of different spray system models and that they each work under different circumstances to produce consistent results. One very effective way to ensure you receive consistent results is to determine which is the best spray system for your needs and preferences, based on the unique circumstances you will be dealing with.
In short, the choice of the proper sprayer for a given application, for any type of liquid, is based on a combination of many factors. For instance, for a paintball marker, one should look at the type of powder you are using. An article from the National Association of Paintball Fields (NAPPS) entitled "Residential Paintball; Paintballs are 50% Surface" describes the differences between modern synthetic, modern gel, and the older halogen class markers. It also describes the features of today's outdoor/indoor sprayers, in particular the differences in the efficiency of conventional sprayers vs. efficient ones.
