How Center Pivot Irrigation System Functions

By Steven West


When riding a plane, you might come across a view of agricultural lands above as you made a casual glance outside the plane window. As you may have observed, there are circular objects that you can find. Believe it or not, those are agricultural fields or rice fields.

When you get to see one for the very first time of your life, you might question yourself as to what those things are and how they came to be or what makes these circular figures circular. You might find them surprising. Well, welcome to the fascinating world of the so called center pivot irrigation system. Unlike the conventional method of irrigation, this method or shall they say, system does not need much of a manipulation of human after its initial set up.

It irrigates in a circular motion around the central point or pivot point. It is versatile for it can add fertilizers, chemicals, herbicides, and of course, water. Thus, an irrigation process becomes efficient. It only takes one machine for a number of functions to be performed.

This machine has been used in the agricultural sector for barely ten years or more. Because of its ability to increase yields and lessen the waste of water compared to the traditional ones, it is considered as a one of a kind mechanized irrigation systems invented by man. However, it can be a kind of complex system that relies on both new and old technology.

This writeup explains how its functions are carried out. For them to be carried out, the machinery itself must perform properly with the help of its basic and essential components. Pumps, pipes, or sprinkler, make up the earlier version that was invented many years ago. He gathered these parts and assembled them to raise the whole machine off the sturdy ground.

As time went by, modifications had been made. New components were added to support and add functions to its older version. Furthermore, those changes made it rely much on technologies that develop different functions for new ones.

Basically, this is operated by electrical energy, either a public electrical utility or generator, if you have one. Hence, electricity makes its movement and performance of functions possible. This is made further possible by an alternating current with more or exactly one hundred and twenty volts. There is also a type of circuit that makes the LRDU move by the energy it provides.

Its main uses are performed by its panel. Although there are different types of a control panel in every model, the way how it is used and how it functioned are basically the same. As written earlier that it is operated by an electrical source of energy, a control panel contains a command that will send some sort of signals to the central point or pivot until such signal has reached the LRDU.

The movement of last regular drive unit or for short, LRDU can be forward or the opposite. This leads the pivot which is continuously making movements until the next tower type box is in the process of activation caused by an apparatus that establishes a connection between the last piece of a span and second to last piece of a tower. As a pivot point moves down and continues doing so, all other towers will also move.
