Electric spray gun for all types of paint, its optimal use in everyday life

 

Paint Sprayer Information

The electric spray gun for all types of paint has long been widely used, both in industry and in everyday life. To understand how to choose an electric spray gun for walls and ceilings, you should understand the principle of its operation, varieties, positive and negative characteristics of individual types, and specific models of devices.

Design features and operating procedure of a standard device

The device of a typical spray gun includes the following main elements:

  • container for coloring agent;
  • spray gun;
  • pressure control device;
  • nozzle with filter for coloring agent;
  • the head is air.

In addition to all these units, individual models can be equipped (or assume the purchase of them) with a compressor with a receiver or an electric pump, a battery or a conventional power cord with a plug.

Despite some differences in design, the work of all sprayers is identical – blowing paint and varnish materials out of the container for the coloring substance in the form of a continuous cloud of spray. This is the task of a piston, pump or compressor, squeezing the substance through the nozzle by means of pressure.

There are two channels in the spray gun:

  • for air (closed by a valve);
  • for paint (closed with a needle).

A slight pull on the trigger leads to the release of compressed gas. A deeper pressing moves the needle and releases a coloring substance, which, mixing with the blown air streams, is sprayed by a cloud.

Releasing the trigger triggers the return spring and closes the paint supply hole with a needle. Then the air injection stops. This sequence leads to uniform spraying of paint and varnish substances even in the first and last moments of work, preventing the occurrence of drips and droplets.

Types of spray guns

Before choosing a spray gun, it is advisable to familiarize yourself with their types in order to understand their fundamental differences.

Mechanical principle of operation

They are characterized by low accuracy and performance, therefore they are recognized as the weakest in the family. For this reason, such models will be significantly cheaper than their analogues. They are often purchased to solve a simple one-time task (for example, whitewashing).

The mechanical spray gun uses the principle of a conventional pump. A few clicks on the trigger force the air, and when the desired pressure is reached, the valve opens, releasing the coloring substance.

Strengths:

  • elementary design;
  • satisfactory color quality;
  • the application does not require special knowledge and skills;
  • cheapness.

Weaknesses:

  • we need constant manual air pumping;
  • strong dispersion of the suspension, a large loss of material.

Pneumatic principle

The operation of such a spray gun is based on the use of a compressor for pumping air and releasing paint under pressure. Therefore, they are made mainly of light and durable materials (aluminum). The container for the dye can be internal (with a volume of up to 2 liters) and external, which is connected using a hose. In the latter case, the volume is practically limited only by the litre of used containers with paint (bucket, barrel).

Strengths:

  • good color quality;
  • the use of any paint materials;
  • use of external tanks of any volume;
  • simplicity and convenience.

Weaknesses:

  • average dispersion of the suspension, average loss of material;
  • quite a high cost, since this is a professional type of equipment.

Electric air principle

The spraying of substances with such a device does not occur with the help of pressure, but with the use of a pump. The electric spray gun for painting works from a conventional outlet, is quite compact and easy to use, disassemble and assemble. The weight of the device without paint ranges from 1.5 to 2.5 kg. The capacity for paintwork does not exceed 1L. These qualities make such a device a leader among home craftsmen.

Strengths:

  • easy to use, thanks to its portability and light weight;
  • fairly simple maintenance;
  • it is equipped with a large number of nozzles;
  • it has a good performance;
  • low cost.

Weaknesses:

  • high noise level when using;
  • the quality of the paint is slightly inferior to pneumatic sprayers.

Electric plunger (airless) principle

The operation of such models is based on pushing the emulsion out with a special piston (plunger). The absence of an air component minimizes excessive spraying and overspending of paint, but the quality of coloring will not be the highest.

A huge number of models with different characteristics allows you to use these devices in home and industrial conditions. Their main advantage is the ability to take paintwork directly from the can by means of a special hose.

Strengths:

  • ease and convenience of use;
  • easy to clean and maintain;
  • good performance;
  • economy;
  • the average cost.

Weaknesses:

  • the quality of the paint is not high;
  • limited use of paint coatings (only synthetic and acrylic).

Battery principle

In essence, this is the same electric spray gun for all types of paint, only it is not powered from the mains. In terms of convenience and compactness, it is similar to a manual screwdriver.

Strengths:

  • ompactness;
  • ease of use;
  • a large number of attachments;
  • not perfect, but satisfactory color quality.

Weaknesses:

  • the need for periodic recharging;
  • the cost is higher than network analogues.

The best electric spray guns

It is impossible to unambiguously determine the electric spray gun, which is better. Each device has its own characteristics, price, and features. Each consumer chooses a specific model of the spray gun, based on personal preferences. Therefore, the rating is based on the frequency of purchase of the device and reviews of customers who have already tested the model in practice.

The best aerial models

A common feature of electric models is high-quality coloring, provided by the breakdown of paint droplets into small elements using an air jet. However, this principle involves the formation of a cloud of dye, so it is necessary to take care of compliance with safety rules.

Painting is carried out over a wide area, so the unpainted parts must be covered with protective materials, fixing them with adhesive tape to prevent blowing off by the air flow.

Bosch PFS 5000E

The pressure of the system is pumped by a motor with a power of 1.2 kW, and the equipment of the device has a four-meter hose. Devices of this brand, made in green, imply that the device is household. However, the existing capacities for the household will be enough in excess. In fact, this is an electric spray gun for painting a house or any other large object.

Strengths:

  • the ability to use thick coatings;
  • high-quality assembly of the device;
  • simplified device management;
  • placement of the engine on wheels for convenient movement;
  • a large selection of nozzles for different paint coatings.

Weaknesses:

  • the container for the coloring agent is small – 1 l;
  • the need to frequently top up the paint, because the paint consumption is 0.5 l / min;
  • very high noise level, approximately comparable to a vacuum cleaner;
  • there is no need to independently configure the device separately for each type of dye, besides, the order of this setting is not spelled out anywhere in the documents.

WAGNER WP 585 Flexio

The device is of universal functionality with a turbine air injection and a power of 630 watts. The location of the motor in the housing makes the device compact. The presence of attachments for use with different materials and a plastic suitcase increases the comfort in working, carrying and storing the device. This design restricts the use of the spray gun only in everyday life, because it requires periodic respites. But he copes with household tasks perfectly and has only high reviews.

Strengths:

  • the use of X-Boost technology allows you to work with viscous compositions despite the low power of the motor;
  • ability to work with a large range of coatings;
  • the ability to adjust the power of the air flow;
  • the presence of a well-developed operating instructions.

Weaknesses:

  • it requires a certain skill to adjust the spray gun while working with dyes of different densities;
  • rather small holes in the nozzle, which leads to rapid drying of the paint during breaks or at the end of work;
  • small size of the power cord, you will need to purchase an extension cord;
  • the package does not contain tools (brushes, brushes) for washing out coloring substances.

Briefly about the main thing

The choice of a spray gun should be based on the following theses:

  1. For one-time work, where the quality is not important (whitewashing), it is better to use a mechanical device.
  2. To reduce the consumption of materials, a plunger device is ideal.
  3. In a large household or a new building, when frequent use of the device is assumed, it is better to stop the choice on an electric spray gun.
  4. For professional purposes (car paint, painting), it would be more correct to purchase a pneumatic version using an external paint tank.
  5. Working in cramped rooms involves the use of battery models with good indicators of autonomy.
  6. Which spray gun to choose each user should decide for himself based on the estimated amount of work and personal budget.

  The main types of  welding Non-arc welding is more often called contact welding. In contact welding, the electrodes that supply current are applied directly to the metal that is being welded. A short, but very powerful current discharge (thousands of amperes) is applied through the metal located between the attached electrodes. In this case, fusion is obtained only between the applied electrodes.  If the electrodes are located directly opposite each other, then the welded joint is obtained point-wise. Although spot welding is not the only type of contact welding, but it is the most common.  Therefore, the concepts of "spot welding" and "contact welding" are often used as synonyms. The voltage of spot portable welding machine is a few volts. Therefore, contact welding is used mainly for bonding sheet metal. For example, in the automotive industry.  In construction, electric arc welding has become much more widespread. In electric arc welding, there is a ...

What should be a spray gun for water-dispersion paint?

Image
  Types of sprayers When choosing the type of tool, it is necessary to take into account the area of the treated surface. Powerful pneumatic or electric spray guns for water-based paint are more often used by professional painters with large volumes of work. Piston hand sprayers are more suitable for home use. Manual (mechanical) Inexpensive tools with a simple design, outwardly resemble old-style automobile pumps. The paint is pumped into them using a piston driven manually. The simplest manual paint sprayer consists of the following parts and assemblies: the housing is in the form of a cylinder, inside which there are 2 valves, the first for pumping air, the second for taking paint; a piston pump enclosed in a cylinder; handles in the form of the letter " T " for manual air injection; a spray gun (pistol) with a trigger, to which 2 hoses are connected: a pressure one that supplies compressed air, and a suction one for collecting paint; the latter is equipped with ...
