Spray Nozzle

What is a Spray Nozzle?

 

 

A spray nozzle is a component designed to disperse a liquid into a fine mist or spray pattern in a controlled and in a predetermined manner. Nozzles are used in various industrial processes to control the flow, direction, and pattern of liquids, such as water, chemiclas, or other fluids, within a specific time interval. Droplet size is also of great importance for certain industrial processes to work efficiently and to achieve a desired result.

How the Spray Nozzle is created
 

The spray is created in a process that involves liquid passing through the nozzle and in that process the liquid is transformed into small droplets exiting the nozzle as a spray in a controlled manner. Flow and pressure are two important parameters in this process. Here is a simplified explanation of how a spray is created in a spray nozzle:

Inlet: Pressurised liquid (water, chemicals, or other fluids) enters the spray nozzle through an inlet opening.

Passage: Inside the nozzle, there is often a narrow passage or constriction. The narrow passage accelerates the flow of the liquid and increases its velocity.

Pressure drop: As the liquid flows through the narrow passage, there is a drop in pressure. This drop in pressure is a critical factor in creating a spray.

Droplet creation: The pressure drop, together with the high-velocity liquid being forced through a small orifice or opening, causes the liquid to break up into small droplets. Different types of nozzles create droplets in various size ranges. Droplet size can be crucial for certain processes to work efficiently and effectively.

Exit: The spray exits the nozzle orifice and is directed toward the intended target. The design of the exit opening also determines the direction of the spray and how wide the spray angle will be for a specific nozzle model.

Spray patternThe design of the nozzle and its components, such as shape, size and insert, determines the spray pattern. The spray pattern can for example be a fine mist, a solid stream, a fan-shaped spray, or a cone-shaped spray.

It is important to note that spray nozzles come in many different designs, each optimized for specific applications. Spray pattern and droplet size are crucial to ensure the effectiveness of the spray in various industrial processes. Desired flow rate, spray angle (between 0° and 360°) and droplet size are determined by the type of nozzle model chosen, as well as the pressure of the liquid entering through the nozzle's inlet hole. The composition of the liquid (eg viscosity) and the presence of particles also affect the spray.

 

Spray Nozzle Patterns and Classifications

Spray Nozzles come in various spray nozzle designs and can be classified by their spray patterns.
Spray patterns are influenced by the following factors:
Geometric design of the nozzle outlet
Internal geometry design of the nozzle (swirl part, swirl chamber)
Transfer of the liquid (axial or tangential)
Liquid properties (specific gravity, viscosity)

Hollow Cone Nozzles
Hollow cones produce the smallest droplet size of any purely hydraulic nozzle. The spiral grooves in the swirl inserts ensure an efficient rotation of the liquid, which creates uniform droplets in a ring pattern.

In the axial flow design, the rotary motion of the liquid is generated by the swirl insert or vane. The axial design produces the finest droplets even when compared to tangential. The tangential design contains no inserts and the liquid flows at a right angle, which creates a spiraling rotation inside the nozzle chamber. These nozzles are less prone to clogging.

Full Cone Nozzles
Full cone nozzles spray completely within the interior of a circular area and provide full coverage.
Axial full cone nozzles achieve a uniform distribution of liquid over a circular area. The high precision of distribution is achieved by orienting the liquid inlet to the center of the swirl chamber of the nozzle.
Tangential full cone nozzles have no internal vanes so they are less prone to clogging. The atomizing fluid is tangentially supplied to a swirl chamber, where it is put into rotation.

Flat Fan Nozzles
Flat fan nozzles provide uniform coverage in a narrow line of spray. Typically, the spray is concentrated in the center and tapered at the ends. This axial design is the first choice when a sharply defined spray is needed for concentrated impact and cleaning power.
The flat fan deflector tongue-type nozzle is a unique design. The flat fan pattern is generated by a solid stream, where the liquid exits the orifice upon an external deflector plate ( "the tongue” ). The deflector design produces the highest impact force even at lower pressures in comparison to the axial design. Tongue-type nozzles are clog resistant and produce a sharply delimited flat fan pattern.

Solid Stream Nozzles
Solid stream spray nozzles provides the highest level of impact due to the solid jet concentrating its total flow in a smaller surface area.

Tank Cleaning Nozzles
Tank cleaning nozzles are either rotating or static sprays. Rotational sprays are either free-spinning or gear driven and can produce flat fan or solid stream spray patterns. When free-spinning nozzles are used at the optimal pressure, they provide good spray impact for cleaning but in some cases, higher pressures can cause atomization of the spray. The gear driven or controlled rotation gives more impact at higher pressures.
Static sprays produce a concentrated solid stream spray, which is typically used for rinsing applications.

Pneumatic Atomization Nozzles
Pneumatic atomization uses the twin fluid principle, which combines both air (gas) and liquid inside a mixing chamber. The air (gas) is used to break the liquid into finer droplets, which creates the atomization. Pneumatic atomizing nozzles come in two variations: internal and external. The external design is typically used for viscous liquids.

Pneumatic atomizing nozzles can produce two types of sprays. Pneumatic flat fan atomizing nozzles produce a flat spray pattern with extremely fine droplets and spray angles up to 80°. Pneumatic full cone atomizing nozzles are preferably used for applications demanding uniform circular impact patterns or larger spray distances.

Compressed Air Nozzles
Air does not have the same spray characteristics as liquids and these nozzles are used for dispersing air or steam in a concentrated area. Generally, air nozzles have a flat fan or solid stream spray pattern. Lechler's multi-channel air nozzle is designed to blow air through multiple channels, which provides a targeted and powerful airflow.

How to Spray Nozzle selection

 

 

Nozzle type
Each nozzle type is designed for a specific type of target and application. For example, a nozzle designed for broadcast spraying is not good for spraying pesticides over a narrow band. Luckily, most nozzle manufacturers' catalogs have charts showing which nozzle type will be best for a specific job. Check the websites of nozzle manufacturers to reach their catalogs. For more information, contact your county Extension office.

Nozzle size
Nozzle manufacturers' catalogs provide tables and charts showing application rates (gallons per acre or gpa), given a nozzle's flow rate (gallons per minute or gpm) delivered at various pressures (psi) and travel speeds (mph). These tables are useful tools for selecting the appropriate nozzles, pressure and speed to spray chemicals at application rates prescribed by product labels. However, the charts are only for a limited number of travel speed and nozzle spacing situations. There may be situations where the charts will not provide information associated with your sprayer setup (nozzle spacing) and operating conditions (travel speed and spray pressure).

The Apps developed by most of the major nozzle manufacturers can provide you the exact nozzle flow rate required for any given set of application parameters, and identify a specific set of nozzle recommendations for the given application parameters. To find these Apps, simply visit the App Store in your smart phone or tablet and do a search under "Spray Nozzle Calculator” , or some other key words related to nozzle size selection. You may also want to do a search under the name of the nozzle company from which you are interested in buying the nozzles. However, some Apps are not user friendly and sometimes they do not take into account the droplet size requirements when recommending nozzles. Although the Apps and tables in catalogs may expedite the nozzle size selection process, it is best to understand the procedure and the math nozzle manufacturers use to generate the values listed in tables and to recommend nozzles in their Apps.

The procedure used by the nozzle manufacturers to generate numbers in tables and in their Apps is explained below. By following the steps mentioned below, you should be able to determine the exact nozzle flow rate (gpm) required for your spray application parameters. Once the exact nozzle flow rate is determined, you can then look at the catalog to select the nozzle that will provide you the flow rate at a practical pressure setting.

Steps to select the proper nozzle size:
The following steps must be taken to determine the nozzle flow rate (gpm):
Step 1. Select the application rate in gallons per acre (gpa). This is a management decision you will have to make based on pesticide label recommendations, field conditions and water supply.
Step 2. Select a practical and safe ground speed in miles per hour (mph).
Step 3. Determine the spray width per nozzle (W).
For broadcast applications, W = nozzle spacing (distance between two nozzles on the boom) in inches.
For band spraying, W = band width in inches.
For directed spraying, W = row spacing in inches (or band width) divided by the number of nozzles per row (or band).

FAQ

 

Q: What is a spray nozzle used for?

A: A spray nozzle is a simple device used to break apart a fluid flow into a spray pattern. Despite the apparent simplicity of nozzles there are a very large number of different products in our range reflecting the multitude of ways different industries need to spray various fluids.

Q: What are the 3 main types of nozzles?

A: Different types of spray nozzles
Flat Fan Nozzles.
Hollow Cone Nozzles.
Full Cone Nozzles.
Solid Stream Nozzles.

Q: What is water spray nozzle?

A: Water spray nozzles act as metering devices to control the flow of water and other spray liquids. The spray pattern is also controlled by the orifice in the spray nozzle. The choice of the spray pattern includes, flat or fan, hollow cone, solid cone, straight jet and square, depending upon the application.

Q: Does nozzle reduce pressure?

A: In other words, for the same diameter nozzle, a larger flow rate is required to generate a larger nozzle pressure drop. In addition, the more the number of nozzles, the lower the pressure drop presented. The nozzle with a greater pressure drop can produce a higher velocity jet.

Q: How do I choose a spray nozzle?

A: Selecting Your Nozzle Size
To find that, start with your application rate in gallons per acre (gpa). Next, find an efficient and safe ground speed in miles per hour (mph). Then, determine the spray width per nozzle (W). Different types of spray methods will require different spray width (W):

Q: How do you read a spray nozzle?

A: The first numbers are the spray angle and the other numbers signify the discharge rate at rated pressure. For example, an 8005 has an 80 degree spray angle and will apply 0.5 gallons per minute (GPM) at rated pressure of 40 psi.

Q: What is the problem with nozzles?

A: Spray nozzles may become clogged which can impact the liquid's flow rate, impair the performance of the nozzle, or alter the spray pattern. Clogs may come from solid materials in the liquid or erosion as metal flakes from pipes gets trapped in the nozzle's orifice. Performing regular cleanings can remove many clogs.

Q: What is the difference between a spray nozzle and a rotary nozzle?

A: Application rates are lower resulting in a better absorption rate by the soil. Bigger droplet size doesn't get affected by the wind as easily as the sprays. Lower water usage per nozzle means more nozzles running at the same time. Less water used per nozzle = fewer zones needed = saving money.

Q: Which nozzle is most efficient?

A: Optimal shape
The simplest nozzle shape has a ~15° cone half-angle, which is about 98% efficient. Smaller angles give very slightly higher efficiency, larger angles give lower efficiency.

Q: Can a nozzle increase water pressure?

A: Common high-powered nozzles are fire hose styled with a long, thin tube. This concentrates the water and increases the pressure. Remember to only use a high-powered nozzle for appropriate tasks.

Q: What is the most common spray nozzle?

A: In the U.S., the most common hollow-cone nozzle used in orchard and vineyard sprayers is the disc-core type . The disc is paired with a core to achieve a desired flow rate, spray angle, and spray pattern .

Q: Do nozzles increase pressure?

A: When you use a fixed flow nozzle, an increase in flow means an increase in nozzle pressure. Your nozzle reaction here is proportional to the increase in pressure. Typically, with a fixed flow nozzle, if you double your flow, you will quadruple your exit pressure.

Q: What size nozzle is a garden hose?

A: Hose diameters range from 3/8 inch, 1/2 inch and 3/4 inch. The bigger the diameter, the more water is delivered. The most common garden hose thread size is 3/4 inch.

Q: How do I choose a garden hose?

A: Choosing your best garden hose will depend on several factors such as the size of your yard, your local climate and budget. You'll need to decide what garden hose material, durability and flexibility you prefer. The length, diameter and fittings you select will determine the hose's capacity.

Q: How do I choose a spray nozzle?

A: Selecting Your Nozzle Size
To find that, start with your application rate in gallons per acre (gpa). Next, find an efficient and safe ground speed in miles per hour (mph). Then, determine the spray width per nozzle (W). Different types of spray methods will require different spray width (W):

Q: What are the 3 main types of nozzles?

A: Three designs of nozzle can be made to produce hollow cones: spirals, axial whirls and tangential whirls.

Q: What is a spray nozzle called?

A: A spray nozzle or atomizer is a device that facilitates the dispersion of a liquid by the formation of a spray.

Q: Can you put round up in a hose sprayer?

A: We usually do not recommend applying herbicides or fungicides using a hose end applicator. Applying using a hand held or backpack sprayer offers better accuracy of application.

Q: Can you connect a pressure washer gun to a garden hose?

A: One set of connectors connects your spigot and your garden hose. Another set of connectors connects your garden hose to the pressure washer, then the third set connects your high-pressure hose to your pressure washer pump. Some kits even come with a connector for attaching your spray gun to your high-pressure hose.

Q: Why won't my garden hose sprayer turn off?

A: This problem is typically caused by a damaged trigger or valve that prevents the flow of water from stopping when the trigger is released. To fix this issue, check the trigger and valve for damage. Look for signs of wear, cracks, or other damage.
