The principle of operation and scope of the high-pressure spray gun

The use of a spray gun is a necessity in many types of production, repair or construction work. Manual painting takes a lot of time, requires too much paint consumption. Of course, it is optimal to apply the paintwork composition by spraying with a special tool. It is best to use a high pressure spray gun for this.

Where you can’t do without a device

There are many areas where a spray gun is used:

1. In furniture production, as well as in woodworking, an airless spray gun is used to apply antiseptics, paints and varnishes to the surface.
2. Auto repair shops and service stations often use a spray gun to paint a car body or to apply an anti-corrosion compound.
3. During construction or repair work, a gun is simply needed for painting and whitewashing surfaces.
4. In private workshops, an airless device is needed for decorative work. It is better to apply the drawing with a spray gun through a stencil; it must also be used in airbrushing.

Sometimes during repair it is necessary to cover a fairly large area with stain, varnish, paint. If compared with manual painting, then, of course, spray painting takes less time and effort. All that is required of the user is to direct the spray gun at the surface to be painted. The result is a perfectly even coating. With this type of staining, there are no stains and streaks, the products acquire a beautiful appearance.

Therefore, it makes sense to acquire this particular tool. But before buying, you need to find out which painting gun is right for you, make a choice. Now there are many spray guns, different in cost, quality and performance.

There are two types of spray guns:

• airless;
• pneumatic.

Consider exactly an airless gun with an electric motor. It has well-balanced engine and gun parameters. And in the pneumatic spray gun you have to choose the parameters of the compressor and the spray gun yourself, and this, of course, is not so convenient.

What does labeling mean?

Low-cost spray guns use HP technology. A feature of HP is a very high pressure, which during operation rises to 5-6 bar, and in a small air flow rate. Using the HP gun, you can easily and efficiently paint even the largest surfaces.

Technical parameters of spray guns

When choosing a spray gun, it is important to know its purpose, that they can be sprayed:

1. There are spray guns created specifically for working with materials based on an aqueous solution, and there are universal guns that can work with absolutely all types of paint and varnish products, any solutions and compositions.
2. It is important that the spray gun has the ability to adjust.Airless spray guns always have at least a few adjustments. Typically, the volume of paint supply is adjusted and the shape of the torch is adjusted. More modern and expensive models have an electronic adjustment of the material supply, it is necessary to have a spray mode adjustment, you can even adjust the piston speed, there is a pressure setting.
3. The type of container where the paint, solution or composition is poured is also important. The most convenient are the tanks, which are located below and are made of transparent material. This allows you to see how much paint or solution is left.
4. It is desirable that the tank was of maximum capacity, since for large volumes of work the small built-in tanks are simply not enough. It is best to choose a spray gun that can pump paint from a separate tank next to it.
5. Some spray guns have fairly long pistols with a special device for turning at different angles and convenient extensions. Thanks to these devices, it’s much more convenient to work, you can paint surfaces without using a stepladder. For example, when painting the ceiling, the spray gun needs to be kept close to the surface, and the use of the above devices will help a lot here.
6. Now there are already spray guns with a laser target pointer. The laser target pointer facilitates the work of novice painters, showing them the working distance.

Principle of work and scope

In the process of spraying, material flows through a hose into a spray gun under high pressure. The airless spray gun has a special nozzle in which the holes have a very small cross section. These openings are much smaller than air-spray guns. The material is economically distributed through small holes using high pressure, which forms a good outline of the spray torch.

Advantages of an airless gun:

1. The main advantage of high-pressure spray guns is that almost any viscosity paint can be used in the airless spray process. Other spray guns, for example, pneumatic ones, have significant limitations during air spraying - the material must be quite liquid.
2. In the process of working with an airless gun, paint flies out under pressure, easily overcomes air and neatly lays on the surface. Therefore, the amount of useful paint transfer using an airless gun is much larger. The productivity of painting work performed by airless spray guns is several times greater than the same indicators when using a pneumatic gun.

Spray guns are used in the following industries:

• in industrial production, in the manufacture of large products of simple forms;
• during repair and construction works at residential and industrial facilities for painting large volumes of surfaces.

High-pressure spray guns are always in demand in the following enterprises:

1. Car building and car repair plants use airless paint sprayers for the production and repair of cars.
2. Repair and construction organizations use this tool for painting various surfaces.
3. Often used spray guns organizations that apply flame retardant coatings having significant viscosity.
4. In enterprises engaged in the manufacture of doors and windows, soil is applied with an airless spray.
5. In shipbuilding, container ships, tankers, bulk carriers, passenger ships are painted using a spray gun.

High pressure atomizer has a low price and is very easy to operate. With its help it is easy to perform any work associated with the application of paints and varnishes.If you need high quality with a large amount of work, then the best choice is an airless spray gun.
