When choosing painting equipment, first of all, you should decide on the scope of future work, as well as how often you will have to use this equipment. The type of equipment needed and its power will directly depend on these parameters. In principle, most models of this equipment can be conditionally divided into professional and household.

Naturally, if you plan to use the device a couple of times a year, and even then only to paint a bench or a fence in the country once, then there is no point in spending money on an expensive professional option. And, on the contrary, if the equipment is used on an ongoing basis and for professional work, then a simplified household sample simply cannot cope with the loads typical for such volumes. At the same time, the type of consumables used (paints) and general working conditions (weather, permanent power supply, etc.) should be taken into account. Thus, various spray guns are suitable for domestic use, and for professional work it is better to use high-pressure paint equipment or airless equipment. With the help of the latter, it is easy to paint surfaces over a large area, because this technique has high performance indicators. In general, professional installations are mostly used in mechanical engineering, construction, and in the restoration and architectural business.
Household models usually work with paints and varnishes of a low degree of viscosity, and therefore do not need to issue particularly high powers. They work from a standard electrical outlet and their principle of operation is to simply spray the coloring mixture.They are distinguished by their relative cheapness and the ability to cope with small amounts of work in the field of painting.
Professional models include high-pressure installations, with airless spraying of membrane or piston type. This equipment has a fairly high capacity and is capable of spraying a variety of different materials - from lime whitewash and primer to metal flame retardants, zinc paints, enamels, epoxy compounds and putty. In addition to standard building mixtures, professional equipment can spray stains, varnishes, impregnations. Even in agriculture, they can be used: they can also be used to treat plants with chemicals.
Modern types of painting machines can be used to perform the following operations:
Airless spray painting equipment has established itself as the most economical, user-friendly and productive group of devices. With their help, large volumes of work are easily performed, although they can also be used for minor cosmetic repairs.The main advantage of this category of devices lies in the fact that, despite their efficiency, they give out a high quality of object coloring - the result of the work will be a uniformly applied layer of paint. All this is achieved by supplying the dye under high pressure.
Various variations of airless equipment can adjust the saturation of the spray, which will allow you to control the flow of the coloring substance, set the pressure level and control other parameters. From this it is clear that by adjusting the settings it is possible to paint both a large and long fence and a small and narrow window frame equally well.
As a special advantage of airless technology, professional painters highlight the possibility of its work with materials of increased viscosity. A standard spray gun, for example, is not adapted to work with such materials and its design will easily become clogged with consumables and become unusable. An airless machine, using high pressure, will properly spray the viscous mass, creating a thick and even layer on the surface to be painted.
Airless models may differ in:
Such devices have a special diaphragm pump and are mainly used to work with not too viscous or completely liquid paints, oriented to the treatment of any surface (concrete, brick, wood, metal).The pump of these machines has a special design: the motor sets the rotation of the shaft, which is equipped with an eccentric, and as a result, the rotational movement of the shaft is transformed into the translational movement of the piston. The piston, in turn, pushes the membrane, which creates a rarefied atmosphere in the pressure chamber, whereby the dye is drawn. Further, the paint is fed through the valve to the spray gun, but if the trigger on it is not pressed, then the paint returns to the collection container.
Membrane equipment has become popular due to its low price, technical simplicity and overall reliability. Even a novice painter with minimal experience is able to work on such a device. Depending on the conditions of future work, the membrane apparatus can be equipped with a fuel or electric motor. Naturally, if you have to work in a fire-explosive production, then it is preferable to use equipment on an electric motor (such samples are marked with the letters "EX"). Fuel models are suitable for work in areas where there are no power sources.
The advantages of membrane machines for painting include:
At the same time, the disadvantages of membrane devices include:
Immediately it is worth mentioning the qualitative advantages of piston machines, which include:
At the same time, this technique also has a number of disadvantages:
Electric piston devices are excellent for working with viscous and medium-viscosity substances. If in membrane machines the intake of the coloring matter was carried out by a membrane, then in this case the piston serves as a working element. It produces forward-return movements, thereby sucking the beauty out of the intake tank.The electric motor is connected to a piston mechanism, which transforms the energy from the rotation of the engine axis into forward and backward manipulations of the piston.
IMPORTANT! Electric piston technology is not intended for super-viscous paints, but this does not prevent it from being used for applying putty and plaster. For appropriate operations, the viscosity of the substance used must be taken into account.
Hydraulic driven machines are designed to operate in difficult conditions and can handle very thick formulations. The basis of their design is a hydraulic pump, which can be driven by an electric motor or a fuel engine. This functioning system allows the piston to perform no more than 40 cycles per minute, and this significantly increases productivity and allows the application of texotropic paints of increased viscosity. At the same time, operating pulsations are reduced to a minimum level, which ensures constant pressure throughout the system.
IMPORTANT! With permanent manual adjustment, premature wear of the working elements of the structure may occur. In hydraulic samples, this situation can be avoided due to the operation of the automatic adjustment system for the movable seal pack, as well as due to the coating of the intake tank with a wear-resistant composition. All bases that come into contact with paintwork materials are made of stainless high-quality materials and are resistant to the negative effects of chemically aggressive and abrasive substances.
With piston hydraulic models it is possible to apply anti-corrosion protection, epoxy resins, refractory and bituminous mixtures.
Pneumatically driven equipment is used for industrial work with thick and liquid substances. The main advantage of such devices is that they can be used at hazardous facilities with a high degree of fire and explosion safety.
The working part is presented in the form of a piston pump operating on the efforts of a pneumatic drive. When compressed air is supplied through the reducer, it is supplied in turn to the upper and lower compartments of the air motor. As a result, the pump plunger together with the piston rod produce translational-return movements. The plunger and valve system form a discharged atmosphere and the paint is fed into the body. When moving in the opposite direction, the clan is closed, and the coloring substance under high pressure passes through the hose to the spray gun. Thus, thanks to such a system, it is possible to use piston pneumatic devices with both liquid and superviscous consumable coloring materials.
IMPORTANT! For pneumatic models, in order to improve the quality of painting, it is recommended to adjust the spray pattern with air flow.
These machines also belong to the group of airless painting equipment and are used for marking the roadway. Most often they are bulky devices installed on the basis of ordinary heavy vehicles, but today there are also small-sized mobile variations that cost much less. The latter, as a rule, have a gasoline internal combustion engine, have a wheel frame with a control console and a pistol-type sprayer.
Their nozzle can be different in diameter, which makes it possible to apply different marking lines.Through airless spraying, the pattern on the road is smooth and clear. Depending on the selected sample, you can apply different types of markings - from the usual two-lane to curly. The machines described are commonly used for road marking, football field processing, parking lot markings, and in large shopping malls (to indicate the direction of travel).
In addition to the painting installation itself, additional work items will be required for full-fledged work. They are able to increase the functionality of the device, increasing its productivity, while facilitating the work of the operator. These include:
As professionals say, the selection of a painting installation cannot be reduced to a completely clear and harmonious algorithm, because different manufacturers include various options in their models that can either be duplicated or simply absent in seemingly similar devices. The same can be said about completely simple machines and highly specialized installations.
However, the purchase of a painting installation must be preceded by a thorough analysis of future working conditions. High-altitude painting can be called work with difficult operating conditions, because in this case the machine will need to have an appropriate range of paintwork supply and it will not be superfluous to provide it with a set of additional nozzles.
Another important factor will be the intensity of future work, its overall frequency, as well as the type of coloring consumable used frequently. From this it is clear that under certain conditions the apparatus may need a device for heating the consumable mass, a device for mixing several components for spraying, etc.
It will not be superfluous to take care of the quality of the brand-manufacturer. Semi-professional models from a little-known brand are hardly suitable for permanent and intensive work.
