MICRO-SPRINKLERS/EMITTERS ASSORTMENT
A particular case
At times farmers are faced with situations that require choosing the most suitable solution, e.g. when
irrigating in tunnels wider than 8 meters or in a greenhouse with spans up to 12 meters and the grower
wants to use only two micro-sprinkler distribution pipes per span.
Therefore, we offer two alternate solutions for situations in which the
span/tunnel to be irrigated is 8 to 12 meter wide:
A)
One way is to use SpinNet™ micro-sprinklers in full-overlap between
adjacent distribution pipes. Thus, at the center between the two
distribution pipes, there is full-overlap, but on the other side of the
two distribution pipes the micro-sprinklers are not "assisted" by micro-
sprinklers on an adjacent distribution pipe.
In such a case increase the distance between the two distribution pipes
(according to the type and performance of the selected micro-sprinkler)
as a means to utilize the overlap at the center, while reducing the area in
which the micro-sprinklers are not "assisted".
B)
Another way is to utilize the advantages
offered by SpinNet™ SD micro-sprinklers.
Consider the area to be irrigated as two
separate strips. Place a distribution pipe
above each strip.
Consider that in this case, one of two effects
will occur depending on the emitter wetting
area diameter (the micro-sprinklers wetting
area is not razor-sharp, it is a blur) and the
distance between adjacent distribution pipes.
The center between the two irrigated strips
(usually serving as a pathway without crop)
may be over- or under-irrigated while on-strip
overall distribution uniformity is high.
