What are the irrigation nozzles and how to choose them?

In order to organize the water supply system to the garden or lawn, nozzles are most often used. It is a necessary element in an irrigation system that allows the supply and spraying of water in a specific area. But before choosing equipment for these purposes, you should understand the main characteristics, types, reliability and efficiency of such devices.

Irrigation nozzles are an element of the system for supplying water to a specific area. They are also called sprinklers or microjets. Such devices are used for irrigation by microspray or in aeroponics systems.

Such devices are used in order to:

• provide appropriate care for plants, supplying them with the right amount of water;
• facilitate human labor and exclude him from the irrigation process;
• prevent soil erosion, since fine droplets do not wash out the soil and do not form specific depressions in it, which are observed with other methods of irrigation;
• deliver water to a fairly large sector of the site.

Currently, equipment for automatic irrigation of a vegetable garden or lawn includes a hose system, a motor, a pump, sprinklers and nozzles directly. But the characteristic of water supply does not fundamentally affect the choice of diffusers, which have certain technical, design and operational parameters.

There are the following nozzle options on the market that are used for the irrigation system.

1. Fan design It is used as a garden sprinkler only when it is enough to raise the water from the ground level using a pressure head and a nozzle to a height of 10 to 30 cm.This option is chosen by those users who need to organize an irrigation system at a certain length of the site.
2. The second type is umbrella nozzles. In this case, the sprayer is fixed directly to the pipe, which is buried inside the soil to a depth of no more than 40 cm. During irrigation, water jets are formed, which in shape resemble an open umbrella. Thus, such a system has certain characteristics.
3. Rotary nozzles, or the so-called circular nozzles, exist in several versions. The consumer has the opportunity to choose equipment that can ensure the delivery of water over a short, medium or long distance. On average, the length covered by the jet hits 20 m. The angle of inclination of the rotary nozzles is adjustable. It can be between 10 ° and 360 °.
4. Pulse variation suitable when you need to cover a large enough area of ​​the site. Most often, impulse nozzles are chosen when it is necessary to provide a directed delivery of water. The irrigation radius in this case is 7 m.
5. Oscillating nozzles also called swinging or pendulum. Their main characteristic and distinctive feature is irrigation of a rectangular area. If we compare them with other products, then we can say that they have absorbed some of the characteristics and parameters of fan and rotary varieties.But it should be borne in mind that here several nozzles are built into the design at once, which work as one unit. The distance between them is on average 5 mm.

In addition to the fact that it is necessary to navigate in all the variety of designs, it is important to choose a well-known brand that values ​​its name. After all, it depends on the manufacturer how well the equipment will work and how long it will last without changing its main characteristics and features.

Experts recommend paying attention to the following popular models and brands.

• Fiskars 1023658 Is a well-known manufacturer of construction and garden equipment. And a particular model has a pulse-like nozzle. Differs in high-quality performance, but the design works only in one mode.

• Gardena 2062-20. The model belongs to the rotary varieties and is capable of covering an area of ​​310 m² with a jet of water. There is a special stand for secure fixation of the sprayer. It is also worth considering that such a design from the Gardena trademark works quite quietly, which allows it to be placed in the immediate vicinity of the house and windows. No noise will disturb the calm.

• Another model from Gardena - 2079-32, which belongs to oscillating devices. This option should be chosen by those who plan to control the amount of fluid discharged.

• Green Apple GWRS12-04. The design refers to sprinklers of a circular type. Therefore, it is perfect for a site of the same size and parameters. 16 nozzles quickly enough to irrigate the desired area.

Before choosing a system for irrigation with water for a specific area, the following recommendations of specialists should be taken into account.

1. Be sure to consider and take into account the area on which this equipment will be fixed. The shape and dimensions are taken into account.
2. It is also important at the time of purchase to take into account which plants need to be watered. Indeed, for low-growing crops or tall trees, it is necessary to choose different models.
3. If the section is long and narrow enough, fan structures are used. They are especially popular for garden paths or a plot of land along a fence. In this case, water, if properly set, will only hit the ground, leaving the asphalt dry.
4. Watering systems that are suitable for use in a greenhouse are umbrella or oscillating options.

It is also important to correctly adjust the irrigation equipment in terms of the radius and length of the jet.

• On some models, the jet angle varies from 10 ° to 360 °. Thus, it is possible to provide irrigation either at the maximum distance of up to 30 m, or at the minimum distance of 3 m.
• Also, adjustment is carried out according to the throw distance. But before buying, it is important to note that these parameters cannot be configured for every equipment. Therefore, if there is a need to really change the characteristics of the water supply, then only those designs and varieties should be chosen where it will be possible to change the values ​​of the angle of inclination and throw distance of the jet.
