A hose is the most efficient tool for watering a large number of plants at once, quickly cleaning a dirty car, or filling a paddling pool for summertime fun. Water can be transported quickly and easily with a hose, saving you time and the strain of carrying heavy containers. In addition, they are adaptable to your specific needs by way of a wide selection of nozzles and accessories. You may not need to buy separate tap fittings if you buy a hose that has them built in, but you should verify this before making a purchase. The tap-to-hose connection is crucial, and most hose connectors are interchangeable between different accessory brands with the same diameter hose. Consider whether or not the hose you buy can withstand the cold and sunlight. While the vast majority are, you may want to store any hoses that fall into the more budget-friendly category somewhere out of the elements this winter, such as in a shed or garage. A word of caution before you stride out, hose in hand: be sparing with your watery jet. A hose can waste a lot of water in a short amount of time. Use water faucets sparingly and immediately after using them so as not to waste any of the precious resource.
A spray nozzle is a basic tool for creating a spray pattern from a fluid flow. Despite nozzles’ apparent simplicity, we have a vast selection of devices to accommodate the many ways in which different industries need spraying. We are the Spray Nozzle People because we have established our company on providing advice on and selling the simple nozzle, which is why our product catalogue has hundreds of different nozzle designs. Flat fan, solid stream, complete cone, hollow cone, and mist/fog are the five primary varieties of spray pattern. In order to achieve these results, several types of nozzles are used, and the sections that follow will go into further depth about each of them. Since air atomizing nozzles may be adjusted to produce a wide variety of patterns and function in a fundamentally different manner from hydraulic nozzles, they warrant their own subsection. Similarly, all of the tank cleaning nozzles and heads have been neatly categorised in their respective space. Finally, there is a category for nozzles that provide a unique role but don’t fall under any of the other categories.
Flat fan nozzles
The spray pattern looks like a line if you look at it from above, but it’s actually a flat fan. When compared to solid stream nozzles and full or hollow cone spray patterns, this spray has a significant impact. Although very fine droplet flat fans can be produced by some air atomising flat fan nozzles, the droplet sizes produced by this type of nozzle are larger than those produced by cone nozzles. Using a flat fan nozzle to cover ground necessitates some sort of relative motion. Typically, a conveyor belt will move the product under a series of flat fan sprays to create this motion. Another option for comprehensive coverage is to set the nozzle in motion.
Design variants of flat fan nozzles
Both elliptical orifice and deflection designs are utilised frequently for hydraulic flat fan nozzles. Pneumatic or air atomizing nozzles can be used to make flat fans with a very small droplet size. If you use the blue navigation bar on the right, you can learn more about the various pneumatic design options available. Please refer to the site’s air atomizing section for information on flat fan nozzles designed for atomizing air. The flat fan nozzle cheat sheet, accessible via the orange tab on the right, contains a summary of all available information on the many different flat fan nozzle designs. If, however, you are certain of the nozzle style you need, you can access the corresponding data sheets by clicking on the boxes below.
Hollow cone nozzles
Droplets are most densely packed in the hollow cone pattern near the spray cone’s outer rim. The central region of the cone collects almost no fluid. In applications like pasteurization, where the target needs to be heated up or cooled quickly, hollow cone nozzles are ideal because they produce the smallest drop size, which gives the spray a greater surface area, allowing for a quicker heat transfer. This spray pattern is medium-impact, having less of an effect than the flat fan or solid stream patterns but more than the misting or full cone patterns. Each of the four nozzle types can create different hollow cone patterns. You can learn more about each of these specific layout options by clicking on the blue links in the sidebar on the right. There, you’ll find detailed descriptions of the salient qualities and advantages of each product family that employs that particular design philosophy. The orange button on the right will take you to a summary of the characteristics shared by all of our hollow cone nozzles, where you may make direct comparisons.
Full cone nozzles
Many different kinds of full cone spray nozzles are available from SNP. In this section of our website, you’ll find specifics on each full cone design variation and how those variations affect spray properties. Click the orange nozzle selection box on the right to get a comparison and overview of all available complete cone nozzles.
Full cone pattern features
The fluid distribution in the entire cone design is very uniform across a given region. Keep in mind that the spray will keep its entire cone pattern for only a limited distance from the orifice before dispersing into a fog or mist. The nozzles described in this section are designed in such a way that, for the longest feasible distance after departure, the whole cone pattern continues to be produced. A misting pattern nozzle should be considered in place of a standard spray nozzle if a consistent mist or fog is desired. Please visit this link for a variety of spray pattern nozzles.
Finely atomized fluid with little velocity characterises fog and mist patterns. The nozzle has little to do with the final shape of the generated fog, which is uniform and follows the paths of the surrounding air currents. This pattern is generated by both impingement and tiny orifice designs.
After a given distance from the orifice, many nozzles’ complete cone or hollow cone pattern dissipates into a fog or mist. In order to achieve the appropriate cone shape, this disintegration into a genuine mist should be avoided. However, there are cases when the spray has to be broken down into a real homogeneous fog. As a result, a variety of nozzles exist for the express purpose of creating this result. Mist is characterised by a slow flow rate and tiny droplet sizes, which have essentially little effect. Evaporative cooling, moistening, and humidifying are typical uses for this pattern.
Air atomising nozzles
In direct pressure nozzles the fluid is broken up (atomised) into droplets by either impact on a surface or by the shearing force caused by passing the liquid through a shaped orifice. In both cases the energy required for the atomisation comes from the potential energy of the fluid itself. Essentially the energy available for atomisation is a function of fluid pressure. In air atomising nozzles pressurised air (or other gas) is used to impact upon the fluid being sprayed. The collision of the gas causes the fluid to split apart into a thin spray. This means that the energy required for atomisation is no longer dependent on fluid pressure because of which very fine sprays can be produced at low fluid pressures. This enables for extremely fine, low volume sprays to be delivered.
Electrically actuated hydraulic nozzles – like the PulsaJet® – enable the fastest operation without the misting produced by air atomizing nozzles.
Electrically actuated air atomizing nozzles feature fast, intermittent operation with the smallest drop sizes and lowest flow rates.
Air actuated hydraulic nozzles are specially designed to precisely disperse and meter pressurized liquids.
Air actuated air atomizing nozzles use compressed air for both on-off operation and liquid atomization
