From the high flow nozzles used for aerospace to the low
pressures nozzles that are widely used in pharmaceutical industry, there are
many different types of nozzles available in the market. Also, nozzles can be
custom built according to some specific requirements. The type of nozzle is
very crucial to the result you desire to yield. So it becomes inevitable to
choose the right. Here is in this blog I will try to shed light on various aspects
of the nozzles including spray pattern – a kind of nozzle testing in which the
pattern of nozzle and other vitally important things are examined.
Before I talk about other vital considerations that you
should make when it comes to choosing a nozzle for industrial use, let me take
a look at the spray pattern – the method used for nozzle pattern testing.
What it is spray patternation testing?
Patternation testing is a method used for examining the
pattern of a spray nozzle. The SETScan optical patternator is used for nozzle
testing. A nozzle of any size can be tested. And there is a certain technique
used to test the nozzle of a fixed size. Take for example, OP – 600 Model that
is used to test a spray with diameter of 7 inches.
Spray pattern is also used for spraying frequency, nozzle
pressure, spraying fluid. Check below the kinds of details this testing method
provides you:
·
Cone angle
·
Presence of streaks and voids from color-coded
contour maps of the spray cross-section
·
Local surface area of drops per unit volume
·
Asymmetry ratio
·
Patternator number
So when you want to get a nozzle used in a spray for
painting, then you should make sure the nozzle you want to buy pattern tested.
And it has been found ok for the kind of work you want to do with that.
There are various kinds of industrial nozzles. And each is
built to do a certain work. You should choose a nozzle keeping in mind what you
want to do. For example, if you need a nozzle for the machines used for
pressure cleaning, you need high pressure nozzles that can allow you to throw
water with high pressure.
High pressure nozzles are widely used for automated cleaning
systems that have made cleaning a piece of cake. The most common nozzles are
simple pressure nozzles, air assisted nozzles, impact nozzles, etc. So when you
need to buy a spray nozzle, make sure the nozzle is spray pattern tested, and
has the pressure you required. And the most importantly, it fits your budget.
