Here are 10 reasons how you can review and update your center pivot irrigation for more return on your investment:
- Add pressure regulators to compensate for changes in pressure and flow stabilizing
- Replace old technology to improve the efficiency of your irrigation
- Improve the uniformity of distribution
- Operate at lower pressure to save energy
- Increase the yield and the net per hectare
- Adjust the flow rate requirements of the soil and crop
- Change worn sprinklers and nozzles
- Minimize operating expenses
- Take advantage of local programs to minimize the cost of electricity
- Ensure efficient capacity and yield by having your center pivot routinely inspected
Facts to know:
- Jump height, measured vertically from the upper level to the lower level, or pressure available (MCA)
- Flow rate in LPS (liters per second).
- If there is a penstock (length and diameter), the different sections (the lengths and diameters of each), and the material and thickness thereof. In the case of long pipelines, it is best to know the approximate profile thereof which is sensitive to the lengths and heights of the various sections.
- Being a high jump in which there is still driving, be aware of the water pressure aka gross head, length and diameter for that measure.
- Height above sea level, the ground where you want to install the mini-turbine.
- Height existing or desired from the floor of the installation of the mini-turbine until the water level in the outlet channel.
- Which projects give energy, that is, whether it is absorbed by the plant (should know that power and intensity need) or if we provide it to any third party individuals or distributors.
There is no way to determine the price of your pivot irrigation system without knowing the exact design needed for your system.
That is why ensuring the proper pivot irrigation system design is crucial. These are the keys to ensuring proper design:
- Know the shape of the plot and your plot’s exact measurements.
- Have a scale drawing with dimensions level. Be sure it identifies the point of making water and electricity to meet the flow and pressure available, soil characteristics, area and crop (soil type, slopes, wind zone, type of crop).
- If the surface is rectangular, a linear system is the most optimum.
- If the surface is more square, these systems work best: pivot, circular or sector fixed or removable.
- Identify the following (depending on the machine size and flow rate to apply):
(a) The diameter of the main pipe (ranges from 4 “, 4.5″, 5 “, 6 5/8″, 8 ” etc);
(b) The 14.9 Wheel type (X24, X38 … 11.2);
(c) Whether it should be standard height or high profile;
(d) The type of spray (issuers) and end gun;
(e) The automation necessary or special options: stop position, closing barrel end, or
(f) head autorreversa last tower, remote, dry track, downspouts or drops, etc.
There is methodical planning that needs to go into selecting, designing, and using a pivot.
Here is some information on how to use a pivot irrigation system. For irrigation, you will need to know:
1. The available flow and water quality.
2. The characteristics of the farm soils, especially with respect to depth, absorption capacity of irrigation water (infiltration rate), salinity and alkalinity.
3. Irrigable research and identify outstanding reviews.
4. Determine the water needs of crops and relate storage capacity and soil permeability.
5. Choose pivot irrigation machine and optional accessories according to the above information.
6. Designing the infrastructure (underground pipe, etc..) And select the appropriate pumping equipment.
