All you need to know about spray paint guns
Thanks to spray painting, the old laborious and time-consuming ways of paintwork can now take a back seat. Paint brushes, buckets, the messiness, these guns could not have come at a better time. These gadgets have helped to apply coats more even and also less paint is involved as the system minimizes wastages. Spray guns today have found application in different places, including furniture industry, automotive realm. For whatever job it is, you will need a spray gun. Here are some of the things you should know.
Spray guns in Perth basically consist of a gun system, a pressurized paint cup, compressed air system and a flexible system for connection. The gadgets are made of three basic controls that ensure effective performance. These include a micrometer that adjusts the air pressure, the fluid adjustment for adjusting the quantity of fluid, and a fan control that is instrumental in regulating the pattern with which spraying is done. Spray guns contain two passageways one for air that is blocked by an air valve and another for paint that is blocked by the fluid needle, which fits in the orifice at the tip of the nozzle.
When the trigger on a spray gun gets pulled, the air and fluid needle, both retract to open the orifice. Fluid from the cup then is pulled into the nozzle as air rushes in the air passageway. The fluid simultaneously rushes towards the orifice on the tip of the nozzle. Atomization will then occur at the tip where the paint and air will mix up to form mist spray that will be released.
Types of guns
Below are the most common Perth spray guns available in the market.
Pressure feed guns – These guns use an external source for fluid pressure and are connected by a hose. These are commonly found in industries for it’s here that huge amounts of liquids are moved through the paint systems.
Siphon feed guns – Fluid in these guns is drawn from a cup located below the gadget. It uses atmospheric air pressure that is compressed to create a strong vacuum at the nozzle tip to pull the fluid through the feed tube. An orifice at the lid of the cup allows in air that sends the fluid up the feed tube. This is effective in lowering the overall pressure and reducing siphon effect. They are best for fluids with low viscosity like dyes.
Gravity feed guns – Here the cup holding the paint is located above the gadget. The process is aided by use of gravity. These guns are great for use with high viscosity fluids.
It’s with no doubt that spray guns have made painting of automobiles and other paint jobs far less messy and tedious as well. While you can find spray guns in Perth with siphon feed, pressure feed and gravity feed designs, available are also more technologically evolved guns like HPLV, LVLP and airless spray guns. With the above knowledge, you can purchase one gun fit to accomplish your task.
