Sprinklers

The sprinklers are rotating devices consist of a single tube or double, with one or more orifices calibrated whose rotary motion is provided by an arm that moves due to water pressure, the jet has a rotary motion that is conferred through the sprinkler arm after returning to the starting position by the action of a spring.
These devices can be used directly to pressures from 1.5 to 4 bars or constitute an element of a sprinkling system of large capacity, its range will normally not exceed 25m.

The Irrigation Cannons

The designation of cannon attaches itself to a large spear that rotates slowly around a vertical axis and can deliver up to about 130m3 / h of water at a pressure of 3-6 bar and at a distance of about 50m, which corresponds to an area of more than 1ha.

Irrigation Fixed Cannons

The successive displacement of a cannon is a time consuming operation so that it can choose to install a network with multiple elements, arranged in a square, linked together and running one at a time; starting and stopping are controlled by varying the water pressure power that causes impulses that are detected by an electrical device that allows you to establish a irrigation program and its duration or so detected by a hydraulic device which drives the metering, opening or closing the alimentation valves of the cannon.

Mobile irrigation cannons of continuous advance

The mobile irrigation cannons of continuous advance are equipment mounted in a support with wheels or skids, moving in a straight line and circular surface which corresponds to an irrigated area of about 2400.
On the quantity of water distributed, this depends on the flow of thewater cannon, the reach of the jet and the forward speed and allows to the fixed cannons, a more regular water distribution and a decrease in erosion resulting from successive irrigation impacts in the same area.


Considering the mobility of the support of the cannon and the coil winding hose (or cable) we have:
    - Mobile Irrigation Cannon and table with fixed winding system;
    - Irrigation Cannon mounted on a mobile table towed;
    - Mobile Irrigation Cannon mounted on a automotive table;

Mobile Irrigation Cannon and  framework with a fixed winding system

In this type of equipment, relatively small and lightweight, the cannon is mounted on a stand with wheels or skids, making the distribution of water according to the following schedule:

Irrigation Canon Mounted on a Towed Mobile Board

In these cases, the irrigation canon is mounted on a towed mobile board drawn mobile  where it’s the winding system, the traction can be performed:

      - cable;

      -The hose itself.

For the first, the cannon is mounted on a mobile board that has a towing winch hydraulically actuated and one drum for winding the hose. To start the irrigation is necessary to roll out the cable, setting up the end, and unroll the hose, which length should be half of the cable, connecting to the water source that is half the journey. When the board, pulled by the winch moves the hose due to friction with the ground tends to drag to is front, some volume of earth; so, to avoid this situation generally use another towed board through the hose by the previous one  that has a ‘polie’ which changes the direction of that.
Considering the traction by the hose itself, the irrigation canons are mounted on a legged board that has a coil winding of the driven plumbing by a hydraulic motor and a system of ‘polies’ to guide the advancement of hose before it’s rolled. To start the irrigation unrolls completely the hose, binding to its end at the mouth water then proceeding to its winding by the traction of the hose, passing this by the guide system; the hose, in this situation is subject to a huge tension, however, any friction with the ground. This system can provide a hose up to 600m long and 20m apart have two cannons mounted on a crossbar articulable.

Mobile Cannon mounted in a Automotive Board

This equipment (auto driver cannon) consists of a framework which is mounted self driving a hydraulic motor to drive the wheels and the coil winding of the hose and a steering system to guide plunger hydraulic hose.
Regarding the distribution of the water cannon has a turnover of about 2400, except that the context in which it is mounted to be moved about 400m, the time taken to cover that angle varies from 1 to 1.5 mt.
After the unrolled the hose, which it end connects to water source, the board (cannon) moves towards the water source due to the drive wheels by a piston or a hydraulic motor, which allows the winding of the hose in the reel which had rotation, so there is not any friction of the hose with the ground and there are no traction by the hose. The piston consumes as the energy to develop and apply a dose, about 1.5 to 4% of output and the motor does not consume water but uses some of the pressure circuit of about 0.5 to 1 bar. The pistons are suitable for situations where the pressure available is limited, example of collective networks, and the engines for the larger equipment and the water has more pressure. Regarding the width of the work is about 80% of the maximum projection distance (about 50m) to make an overlay that allows a regular transversal distribution.
