How to Select the Best Rotor Type Sprinkler. The webs mother lode of free irrigation information In order to make good decisions about which sprinkler products will work best for you it is necessary to have some basic knowledge of how sprinklers work and what the various options available to you are. Therefore the following is intended to give you the background necessary to understand the terminology used in my reviews. Sprinklers fall into one of two types based on the method they use to apply water to the ground spray type sprays or rotor type rotors. Spray type sprinklers are the type of sprinkler that spray a fixed water pattern similar to how a shower head works. Rotor type sprinklers use a rotating stream or multiple streams of water to apply the water to the ground. Spray type sprinklers also called spray heads and sprays are typically used for smaller areas. Rotor type sprinklers most often simply called rotors are used for larger areas generally more than 1. Rotor Type Sprinkler Basics. Rotor is the term used to describe the various sprinklers which operate by rotating streams of water over the landscape. The example which most people are familiar with is the impact rotor sprinkler often improperly called a rainbird, Rainbird is the actually the trade name of a sprinkler manufacturer. The impact sprinkler is mounted on a bearing that allows the entire sprinkler body to spin in circles. It is rotated by the impact of a swinging arm which repeatedly strikes the body of the sprinkler, causing it to rotate slightly each time. You probably know the impact sprinkler best for the distinct sound it makes when operating tooka, tooka, tooka, tic, tic, tic, tic, tic, tooka, tooka, tooka, etc. You may run into rotor type sprinklers called cam drives or ball drives. These are also impact sprinklers, however the impact is caused by either a cam or a ball bearing inside the body of the sprinkler. With ball and cam drive rotors only the nozzle moves. Most of these ball and cam drive sprinklers are no longer sold, but a few, like the Rainbird R 5. While impacts do an acceptable job of irrigating, the jerky motion of the impact drive tends to make them rotate in a less than uniform manner. Thus the impact rotors have now been almost completely replaced by gear driven rotors, which are very quiet, rotate smoothly, are lower maintenance, and much smaller in size. As with cam and ball drives, only the nozzle on a gear drive moves. The water moving through the sprinkler spins a turbine, this turns a set of gears, which turn the nozzle. These gear drive rotors have one or more streams of water which rotate silently across the landscape. The prettiest of these are the multi stream rotors or stream rotor where multiple streams of water rotate over the landscape one after the other. Multi stream rotors are fascinating to watch but tend to be higher maintenance than the other types of gear drive sprinkler heads. Most rotors now come with a set of nozzles rather than a single nozzle. Oblivion Walkthrough Pc. Often these nozzles come attached to what is called a nozzle tree.

Save the rest of the nozzles, you may need them later. Multiple nozzles are a big advantage, as you can change to a different size nozzle if needed to help balance your system. Say you have a dry spot between rotors. You might be able to green it up by installing a larger nozzle in the rotors surrounding the dry spot. Some rotors, however, still come with a single, pre installed nozzle, and some come with stripped down nozzle trees with only a few of the available nozzle sizes on them. If you want the whole set of nozzles with these less expensive models, you must purchase them separately. A preinstalled nozzle or limited nozzle tree is common with many of the prepackaged rotors sold at discount stores. I need to mention a new type of sprinkler, which I am classifying as a rotor since it utilizes a moving stream of water. However, it operates a little different from a traditional rotor. Sometimes called robot sprinklers, these sprinklers direct a stream of water to fall on specific spots. This works something like when you use a hose to water the yard, and you move the nozzle of the hose around to make the stream of water fall on different spots. The size and shape of the area to be watered is programmed into a computer, the computer then controls the sprinklers, telling them where to move the stream and how much water to apply in each spot. Typically they use an electric motor to move the nozzle. What situations work best with rotor type sprinkler heads Typically rotors are used for sprinkler spacings from 1. There are rotors available that can be spaced closer than 1. There are also rotors available for spacings farther apart than 5.

When selecting a rotor keep Strykers Rule in mind the water pressure at the rotor head in PSI must exceed the distance in feet between the heads. Thus if you want to space rotors 3. PSI of pressure at the rotor. Caution you will actually need more pressure than 3.

Designing with larger sprinklers requires specialized knowledge as many unique factors must be considered in the design process. How a Typical Gear Drive Rotor Works. Master Pdf Editor 1.9 Serial Key. Water enters the base of the sprinkler. From there it passes through a filter screen and then through a turbine. The water turns the turbine, which powers a set of gears, which rotate the sprinkler nozzle. TIME 2 hours COST Starts at 40 DIFFICULTY Easy In most parts of the country, trying to keep yards watered throughout the summer requires an open tap. The water then passes up through the body and exits through the nozzle. Generally the nozzles can be removed and there are numerous nozzle sizes available. At the nozzle there is a radius reduction screw. With most rotors this screw also doubles as the set screw that holds the nozzle in place. Reducing the Radius and Dealing with Coverage Problems.

Cost To Install In Ground Sprinkler System' title='Cost To Install In Ground Sprinkler System' />As the radius reduction screw is turned clockwise the end of the screw comes into contact with the stream of water exiting the nozzle. This distorts the water stream and results in a reduction of the radius. Many people in the irrigation industry refer to this screw as the break up screw because it breaks up the water stream. There is a temptation to play around with this screw setting in an attempt to create a better water pattern. However, most modern rotor type sprinklers are designed to give optimum uniformity with the radius reduction screw not in contact with the water stream. Therefore you should only turn the screw so that it contacts the water stream if you need to reduce the sprinkler radius. Be warned most people look at the stream of water exiting the nozzle and feel it is not giving a uniform pattern. So they mess with the radius reduction screw trying to get a better pattern. Unfortunately, this most often hurts rather than helps. The fact is that without training the average person cant tell when the water pattern is best by simply looking at it. The moral is if you dont need to reduce the radius of the stream, then leave the screw in a position where it does not contact the water streamIrrigation Systems Toronto Lawn Sprinkler Systems Toronto.
