WATERING SYSTEM WITHOUT THE USE OF SPECIAL CONTAINERS

Send

As a rule, large water tanks located in the corner of the site are used for irrigation systems in the area. A pump is connected to a tank of 3-4 cubic meters. The pump power also depends on the number of nozzles. In order to connect several nozzles to irrigation at the same time, you cannot do without a special tank. But there is a way to connect the irrigation system directly to the water supply or well.
First of all, for the coordinated operation of the nozzles and the system as a whole, a minimum pressure of three atmospheres is required, therefore, the usual automation for water supply from the well should be adjusted to 3-4.8 atmospheres for sufficient water pressure.
Pipe laying is carried out by the beam method.

From the main pipe d. 32 mm. for each nozzle there is a separate pipe f.20.

In place of the nozzle, a column is placed, and the nozzle itself is screwed to the key of this column. This design is innovative. Of course, it is more complicated and expensive, but in practice it has proven itself perfectly. And the money that you risk spending in the future on repairs every now and then failing nozzles, it is better to invest in the installation of a reliable design. In addition, the configuration of the site is constantly changing: old plants are replanted, new ones are planted, and after a year you may need to put, for example, a one and a half to two meter hose between the key and nozzle. The nozzle itself will be bolted to a tripod of a certain height. Changing the location of the tripod with the nozzle and the height of the tripod, you move the nozzle in three planes. In the caisson, a collector is installed with the number of nozzles corresponding to the number of nozzles, an electromagnetic valve is placed on each nozzle (better than direct action). The relay that controls the activation of the valves is located in a drier place outside the caisson. A good option is the PR-110 relay.
Here is an example of a watering system with 12 nozzles. At 23 o’clock the first nozzle turns on and runs for 15-30 minutes with a break of 1 minute. The entire cycle time is 3 hours 18 minutes (with a 15-minute nozzle operation). The advantage of this work is that you can use any nozzle and easily change their places. The best nozzle in terms of price and quality is mechanical. Its only drawback is inaccurate irrigation area, watering where it is not needed. In places where more precise irrigation is needed, it is better to put rotary nozzles.
