Adjusting the spray gun - video material is supplemented with a portion of the theory
There are manual and electric sprayers. Classify the presented mechanisms can be on different grounds: the pressure of the nebulizer( low and high pressure), according to purpose( semi-professional and professional), according to the principle of operation( manual and electrical).With regard to the principle of paint supply, it can be fed from the upper or lower tank, by forced pumping of material, or by using airless or combined spraying.
For home use, it is better to choose an electrical tool that can operate from an ordinary electrical network. It is cheap and practical. Typically, users choose pneumatic devices. The device of the spray gun is not complicated. It consists of the base on which the suction and discharge valve, the pump, the pressure hose, the fishing rod, the lid and the hose with the suction filter are located.
The scheme of the paint spray gun is also easy to understand, and any examples can be found in the worldwide network. With regard to consumables, some users do not really recommend acrylic and latex paints( for electric models).Although for these cases there are also different versions of the devices.
Let's analyze the principle of the
spray gun. One can single out the general principle of the spray gun: the finish is applied using a jet passing through the nozzle. This air breaks the lacquer or other consumables into very small particles, after which a spray "spray" is formed. Naturally, the surface must necessarily be cleaned of any dirt, dust and grease. All shortcomings, cracks, scratches and other damages must necessarily be primed, and the surface itself must be ground.
Before you finish the surface, you need to adjust the spray gun. Only a few parameters are regulated: the air pressure, the feed of the working material, and the width of the torch. The quality of the device and the quality of the finish depend on how well the finishing liquid is diluted.
First of all, the substance is mixed with the activator proposed in the instruction. The proportions must be strictly maintained. However, the paint with the activator is not yet ready for use. Therefore, the solvent must be added to the mixture. After that, you need to try how well the device works, and how smoothly the finishing layer falls.
Adjusting the spray gun - how to bring the device to perfection?
When everything is ready for operation, the device is assembled, the composition is fed to the sprayer, then the spray gun is adjusted based on how well the device will work. The substance must not be viscous. It must be liquid enough that the nozzle does not clog. Acrylic lacquer is diluted in the same way as paint.
Now, before adjusting the spray gun, you need to understand the width of the torch. In some cases, if the surface is large enough, it is necessary to use the maximum width of the torch, and in other cases a small enough width. When the width of the flare is reduced, the air pressure must be taken into account.
The next step in the instruction is "how to set up the spray gun" - adjusting the supply of varnish or other finishing agent. To do this, it is sufficient simply to completely open or partially close the hole through which the composition is fed. After you have adjusted the spray gun according to the previous parameter, you need to adjust the air supply.
To do this, you need a sheet of paper, attached vertically. It is customized for each type of finishing material in different ways.
You've found out how the spray gun works. After some workouts, you can get the hang of setting up the device, and this will happen quickly. If you need to visually see how the spray gun is adjusted, the video can be found in the framework of our article.
