Classification of equipment

The main factor from which it is worth repelled when choosing painting equipment - what volumes you have to do. If you are going to paint the fence or shop in the country, you will use the unit several times a year, it makes no sense to spend a large amount for a professional model. And, on the contrary, if you plan to regularly use the technique, then the budget unprofessional model may simply not cope with high load. Also, the choice depends on the materials used (type of paint), the deadlines of the end of work and conditions at the construction site (there is electricity, the scale of the surface to be painted, etc.).

All types of painting devices differ in target destination, technical parameters and manufacturer. For purpose, they are household and professional (than they differ, you already know). For domestic needs, inexpensive and varied paintopults are perfectly suitable, and professionals are better to purchase a painting device of high pressure or airless technique. The latter is designed for painting large surfaces, and therefore is characterized by high performance and is used in large engineering, construction and for the restoration of industrial structures.

Airless technique

In this article, we will consider in detail the painting devices of airless spraying, as they have proven themselves as the most productive, comfortable and cost-effective devices. They are not only suitable for carrying out large volumes of work, but help to quickly cope with small cosmetic repairs. The main advantage of this class of technology is that with its economy, the devices give the impeccable quality of the surface to be painted - smooth and evenly scrolling layer. This is ensured by a special principle of high pressure operation.

Various models allow you to adjust the spraying intensity, thereby controlling the paint consumption, pressure and other parameters. Thus, you can paint with the same success with the same tool and high fences, and window frames, and more compact products.

Specialists celebrate another important advantage of airless painting devices - the ability to work with high viscosity materials. While other tools can be clogged and not cope with such paints, the high pressure of airless technology reduces the complexity of the work and creates a smooth and fairly thick layer on the surface.

When choosing airless equipment, pay attention to the specifications. The devices differ by the type of actuator and the type of the working item. In the first case, the work can be carried out due to the engine of internal combustion, pneumatic reception or electric motor. Depending on the working element there are piston and membrane machines.

Membrane painting devices

The membrane devices are equipped with a special diaphragm pump and are used mainly to work with liquid and not too viscous paints, regardless of the type of surface (wood, metal, brick, concrete, etc.).

The pump of such machines has a special design: the engine sets the rotation of the shaft equipped with an eccentric, as a result of which the rotational movement of the shaft is converted to the progressive course of the piston. He, in turn, pushes the membrane, and she creates a sparse atmosphere in the discharge chamber, and the paint fence occurs. The paint passes through the valve to the sprayer of the pistol type, and if the trigger is not pressed, returns back to the intake capacity.

The popularity of membrane apparatuses is due to low cost, reliability and unpretentiousness. Even inexperienced person will cope with such a technique after a short practice. Depending on the conditions created on the construction site, you can choose a model with a gasoline or electric engine. If you have to work on a dangerous production, use explosion protection models with an electric drive, on which there is an EX marking. Gasoline machines are designed to work on non-electrified objects.

Electropore painting machines

Electropore devices use electrical appliances to work with medieval and viscous paints. If in the previous case, the paint fence was carried out with the help of a membrane, here the working part is the piston. It performs reciprocating manipulations, sucks the paint from the intake cylinder. The electric engine is associated with the piston mechanism transforming the rotation energy of the axis of the motor in the reciprocating movements of the piston.

Important: Piston devices are not intended to work with high viscosity paints, but this does not prevent them from using them for applying plaster and putty. When choosing a model, be sure to take into account the viscosity of the composition used.

Piston hydraulic painting devices

Hydraulic equipment is designed to work with thick compositions in difficult operating conditions. The basis is based on the hydraulic pump, driven by electric or benzoid.

Such a system of work allows the piston to perform no more than 40 cycles per minute, which increases productivity and allows you to apply trexotropic high-viscosity paints. Pulsation during operation is minimized, and stable pressure is constantly observed in the system.

Important: With permanent manual adjustment, premature equipment wear takes place. It is possible to avoid it here, thanks to the automatic control system of the moving package of seals, as well as due to the wear-resistant coating of the intake cylinder. All surfaces in contact with paint are made of high quality stainless steel and are not afraid of contacts with abrasive and chemically aggressive materials.

Piston hydraulic drivers can be used to apply anti-corrosion substances, epoxy resins, bitumen and refractory mixtures.

Piston pneumatic painting devices

The equipment on the pneumatic drive is intended for industrial work with liquid and thick mixtures. The main advantage of such equipment is that it can be used on dangerous objects where strict explosion safety requirements are installed.

The working element is represented by a piston pump working at the pneumatic reception. When compressed air is fed through the gearbox, it falls into the upper and lower compartment of the pneumotor. As a result, the piston rod and the pump plunger make reciprocating manipulations. The plunger with the valve system creates a discharged atmosphere, and the paint enters the body. When the reverse move is carried out, the valve overlaps, and the coloring composition under high pressure goes along the hose to the spray gun.

Thanks to such a device, piston pneumatic devices can be used as for conventional liquid paints and for high viscosity compositions.

Useful Tip: To improve the quality of the color, use the torch correction system with air flow.

Marking machinery

Placement technique also refers to the category of airless devices and is used to organize a safe movement. Speaking of similar equipment, most recalls bulky and expensive cars, but besides them there are also more mobile and cheap models. They, as a rule, are constructed on the basis of a gasoline drive, have a wheel frame with a console and a sprayer of a pistol type.

Nozzle can change the diameter, which allows you to apply different lines of markup. Airless paint spraying gives a smooth and clear picture. Depending on the selected model, you can get different types of marking, for example, two-band or curly. Such devices are actively used to work on football fields, parking and parking lots, in large trading complexes, etc.

Accessories for the painting machine

In addition to the most painting equipment, you will need various accessories. They significantly increase the multitasking of technology, improving productivity and facilitating your work.

Types of accessories for painting equipment:

the nozzle holder - allows you to securely fix the nozzle, is sold complete with a seal to seal the compound;
checkbox - nozzle operating in spraying and cleansing mode. To switch, you must rotate the 180 ° checkbox. It has three-digit marking indicating the angle of spraying and the diameter of the nozzle. The diameter should be selected depending on the viscosity of the paint (the thick paint, the greater the diameter);
the extension cord is a special nozzle used to proscure of hard-to-reach places. It looks like a fishing rod (long aluminum tube, at one end of which the fixing nut is on the other - the nozzle holder);
the nozzle for painting pipes is a device for staining pipes from the inside. Has special centering guides inside the pipe;
the heater is necessary for working with highly viscous compositions;
filters - allow to obtain high-quality spraying of the composition, differ in the degree of purification;
hoses - lengthen high pressure housing on the required length. Usually airless equipment can supply paint to a horizontal distance of up to 100 m.

Popular manufacturers

So, you already know which airless painting devices are and have already managed to choose the appropriate look. However, now it is necessary to decide on the manufacturer and model. The cost also plays the last role - any owner will be happy to save. Prices for such equipment vary from 30,000 to 350,000 rubles, and several factors affect this: the manufacturer, technical characteristics and purpose. The cheapest devices are produced in China. Domestic products are also relatively inexpensive - from 60,000 to 100,000 rubles, and foreign manufacturers of Wagner and Graco are most popular.

Useful advice: It should be understood that the service life of any painting equipment will depend on the quality of the composition used, the scale of the work performed, as well as the experience of malaria. If you buy expensive American technique, you should not pour in it cheap paint of dubious quality. After completing the work, always rinse the equipment with a solvent designed specifically for the paint used, and periodically carry out maintenance.

Wagner painting machine

American manufacturer Wagner supplies high-quality and fairly expensive airless paint sprayers.

Coloring machine Graco.

Graco is leading in the production of airless painting equipment, since the inventor of this method is inventor. The quality of the highest class products, but also the cost is appropriate, so the painting devices Graco are more often used for professional and industrial works.
