Kraskopult for vacuum cleaner: Description

A vacuum cleaner sprayer is designed with a coloring product tank atop, supplying a consistent amount of paint. The paint is deposited onto the sprayer through a unique aperture. Its spraying is caused by the airflow exiting the vacuum cleaner.

A homemade vacuum cleaner nozzle is constructed from a standard can lid, which covers the existing capacity and increases the volume to one liter. If the lid’s hole isn’t 30 millimeters in diameter, you can use an adapter specifically made for that purpose. This design is easy to make and works well for painting projects.

The principle of operation of the air sprayer

It helps to understand the basic principles of how a factory spray gunner operates in order to facilitate the construction of a vacuum cleaner sprayer. Compressed air is what powers the spray gun, so having a device that generates this movement is necessary. In this instance, a specialized compressor performs this function; gasoline or the power grid powers it.

Pneumatic spray guns are classified as semi-stationary equipment and are powered by strong compressors. They typically have large receiver volumes, up to 30 liters. Options with a smaller receiver volume that are conveniently attached to the shoulder are also available for purchase. The lightweight second option is ideal when it comes to a compressor that looks like a vacuum cleaner because pneumatics requires a higher pressure while vacuums have a lower pressure span.

Speaking about the device of the spray itself, it must be said that it consists of a case with a trigger, a needle, nozzles, a spray part and lower capacity. By pressing the trigger, the master shifts the needle, the tip in the form of a cone of which closes the flow of paint from the nozzle. Two tubes are placed in the container: short and long. The first is necessary to penetrate the air, the second to supply the coloring agent. Due to air pressure, the liquid is pushed out of the container and exits through the nozzle, part of the air is in the air head channels, subsequently going beyond the liquid and dividing it into smaller fractions.

Varieties of spray guns for vacuum cleaners

Vacuum cleaner sprayers were sold in the Soviet era; nowadays, it is nearly impossible to find such a useful rarity for sale. But contemporary equivalents started to be available.

Thus, you will need to buy a vacuum cleaner spray. Such a part, designed for an electric spray with a remote compressor, is available for purchase.

These parts are sold under the two trademarks "Wagner" and "bison" in total. Apart from these companies, no one else manufactures ready-made dispersion options.

Which vacuum cleaner to use

Prioritize power when selecting a vacuum cleaner that can be used for staining tasks such as air injection. The spraying won’t go through sufficiently if the power is out. Additionally, the vacuum cleaner needs to have a dedicated channel; if one doesn’t exist, users must seal off all of the holes in the appliance to limit absorption to the location where the hose is connected.

Options for vacuum cleaners, where the required hole is already present, include the vintage Soviet "Ural," "Pioneer," and other models. Samsung SC4140 stands out among the new models.

However, you can use the available device—this will be explained subsequently.

The advantages of a home -made device

The affordability of such a device is undoubtedly a plus. They don’t need to buy a lot of materials; you can make it with homemade supplies. The do-it-yourself method works well for the task and can make staining much easier. Such a vacuum cleaner nozzle can also be used for whitewashing. Furthermore, if the device is constructed correctly, it will be able to spray well acrylic and water-based paints, which are sometimes difficult for factory spray guns to spray.

How to make

This is the quickest and easiest option if a special nozzle that was attached to the Soviet models of vacuum cleaners turned out to be available. She’s just placed atop a liter jar. The output is then modified to reflect the intended parameters. Additionally, the vacuum cleaner’s hose edge is adjusted to the sprayer’s air intake location; if necessary, an adapter is used to fit the holes in each other. Below is a description of additional manufacturing options.

Preparation of a vacuum cleaner

It doesn’t matter which vacuum cleaners are in the apparatus; you must first remove them. The device’s remaining components must be cleared of debris and wiped. Wet cleaning should also be done in the space where the vacuum cleaner’s sprayer will be assembled.

Necessary details and tools

You’ll need the following equipment and tools to make this unit:

  • Vacuum cleaner;
  • A receiver, a rubber car chamber or a ball is suitable for this purpose;
  • The container where the paint will be poured;
  • Reduction valve;
  • Fasteners.

Production process

In the old apparatus, the direction of traction needs to be changed. Turn the engine the other way to accomplish this. The terminals leading to the rotor and stature are passable. Nonetheless, the thrust strength will still be influenced by the impeller blades. It is preferable to swap them out for an option with symmetrical blades if they have an asymmetrical shape.

Next, set up the sprayer to the necessary pressure. To accomplish this, you must carry out one of the following actions to get any kind of vacuum cleaner ready for use:

  • All available holes need to be closed, for this purpose, mounting foam, heat -mushrooms, epoxy resin and other products are used that can provide reliable sealing. At the place of jacket, a round hole suitable for the hose should be made. Next, a piece of PVC pipe is placed in it, you should leave it outside about seven centimeters. This option is suitable for the old apparatus, which is not a pity;
  • A more humane method in relation to the apparatus. It is necessary to prepare a tight bag of large sizes and the second hose. The vacuum cleaner itself is placed in a package, and the hose from it is excreted out, it closes tightly, for this the island is suitable. Thus, the air will run in the package, and then go down the second hose. For the process to pass without problems, the package should be reliable, and all holes should be qualitatively stacked up.

Following a thorough cleaning of the equipment, 150 grams of solvent are added to the container, and the vacuum cleaner is turned on for ten minutes.

Testing and operating rules

The gadget must first be tested out. In order to achieve this, it is best to stain a small portion of the street’s surface, and it must be kept 20 cm away from any objects. The nozzle’s diameter should ideally be kept to a minimum.

  • The coloring product must be filtered;
  • The conductive channels are washed before and after work;
  • The spraying block should not be turned over during the staining process.

Tips for use

To enable the user to become accustomed to the device, small portions of a painted surface must be worked with initially. The outcome will be better if more layers are created and the thinner they are. When painting the majority of the surface, you must work quickly in a horizontal direction to make shade avoidance easier.

Using a vacuum cleaner nozzle for painting can greatly simplify the process; doing it by hand is not as tough. This process won’t take long if you have an appropriate vacuum cleaner. And the owner will be happy with the outcome.
