Why do you need a spraying tank in painting

Using the proper tools is essential to getting a perfect paint finish. The spraying tank is one piece of equipment that both professional painters and do-it-yourselfers need. This adaptable tool ensures a smooth and even application of paint on a variety of surfaces, greatly enhancing the quality of your paint job.

Dripping and uneven coverage are less likely when paint is applied precisely and precisely controlled with a spraying tank. Paint is applied in a fine mist to help ensure a consistent layer that dries evenly and gives the surface a polished appearance. A spraying tank can make painting intricate details, furniture, or walls more efficient and produce more polished results.

The fact that utilizing a spraying tank saves time is another benefit. Conventional painting techniques, such as brushing or rollering, can require a lot of time and work. On the other hand, a spraying tank covers large areas faster and with less effort. As a result, you’ll be able to finish painting projects more quickly, freeing up more time for other projects or just relaxing in the newly decorated area.

Furthermore, spraying tanks are very versatile because they are made to accommodate different kinds of paint and coatings. When working with latex, enamel, or varnish, a spraying tank can easily handle varying viscosities. It’s a great asset to your painting toolkit because of its versatility, which guarantees you can use it for a variety of tasks.

In conclusion, a spraying tank is a necessary tool for anyone trying to efficiently achieve high-quality paint finishes. It makes painting projects easier and more enjoyable by providing accuracy, speed, and versatility. Purchasing a high-quality spraying tank can improve your painting abilities and enable you to produce results that are consistently professional.

Description of the device

Spraying tanks are frequently used to apply paint in a high-quality, consistent manner. One such tool is a hermetically sealed container that is filled with compressed air and used to stain a lot of the surrounding surfaces. The paint can be mixed until smooth in the tank, in addition to being sprayed directly and "broken" into the smallest particles. The device’s pressure regulator lets you precisely stain a variety of surfaces regardless of the outside environment.

Professionals value the spray-off tanks greatly because of their numerous, indisputable benefits.

  1. Large volume. The capacity of the tank can reach 150 liters, while the spray guns include only 500-1000 ml of paint (or a little more). You will not have to regularly fill the container, therefore, it will be possible to work without interruptions.
  2. The presence of a mixer. A pneumatic or manual mixer is included with the device, which works on the action of compressed air. It allows you to mix paint, which improves the quality of the work ongoing.
  3. The ability to adjust the pressure. A special regulator helps set the pressure that is required in a particular situation. Most often, the working pressure of the devices is an indicator of 3.5-4 atm. The paint from the device throughout the work process is supplied with the same speed and intensity, so the coating will have the same thickness on its entire length.
  4. Ease of use and maintenance. The spray -off tanks are compact, they weigh a little, they can be easily transferred to a new place. The cover of the devices closes very tightly, so that the material will not spill. To access the internal elements of the tank, you just need to raise the lid. Removing and replacing the filter is also not difficult.
  5. The possibility of accelerating work. Each tank involves connecting two sprayers, if necessary. Therefore, two masters can work with equipment at once, and staining will occur an order of magnitude more likely.

Spearfrower tanks are frequently used for extensive finishing and repair work both inside and outside of buildings, particularly in industry and during the building and repair of numerous large facilities.

The design of the tank

Tanks come in a variety of models, but they all essentially have the same design. The device case is a mobile, cylindrical vessel that can be moved around the master bedroom and weighs no more than 20 kg. It has a circular lid that closes from above and is equipped with pneumatic equipment such as gearboxes, compressed air inlet valves, safety valves, pressure regulators, and valves.

Examining the spray-enhanced tank’s interior, the following components are visible:

  • lever;
  • mesh filter;
  • grounding device;
  • axis with blades for kneading LKM;
  • a capacity for a filling of paint;
  • manometer;
  • suction pipe;
  • material crane;
  • Descent valve.

A separate component attached to the spray-off tank is a pressurized cylinder with a cord for connecting to a stationary electrical network or compressor. For a manual mixer, the compressor power can be only 300-350 l/min, and at least 400-500 l/min is required for pneumatic mixers.

Principle of operation

After positioning the spray-enhanced tank on a sturdy, level surface and securely shutting the lid, it starts to function. It attaches to the hose that forms the pressure line and the coloring composition. The paint tank should not be positioned near heat sources or exposed to direct sunlight in order to preserve the paint’s structure and temperature. If not, stain quality might deteriorate.

The device is in the following order:

  • After opening the inlet valve, the paint is filtered with the removal of too large particles;
  • The container for LKM is filled, the composition is mixed with blades;
  • As it reaches the desired level, the pressure discharge valve begins to operate (located inside on the case), the air supply under pressure stops;
  • If the filter is clogged, or serious pressure drops for other reasons occurred, the discharge valve works in an emergency;
  • With normal operation of the filter and valves, the paint enters the paint pistol attached to the tank.

The following guidelines must be followed in order for the device to operate safely and continuously:

  • avoid increasing pressure in excess of 5 atm. (the valve will work at 5-5.5 atm.);
  • do not reconfigure the safety valve;
  • do not change the location of the elements yourself and do not make other changes to the design of the tank;
  • Do not pour abrasive compounds, paint with acids, gasoline, dichloroethane into the device.

How to make a tank with your own hands

Get a compressor first, for instance, by taking an outdated unit out of the refrigerator. A compressor can be purchased at an auto store by selecting a less expensive model. Additionally, the following will be necessary:

  1. Reliable tank-resort. The device is suitable from the brake mechanism of the cargo machine, but not too rusty, otherwise it will not withstand increased pressure.
  2. Copper tube for connecting a tank and compressor. You can take a pipe from a different metal, but copper is better than others.
  3. Contact pressure relay. Will help adjust the pressure at the right level.

After being connected to Baku by a flexible reinforced hose, the existing spray gun is ready to be used for its intended function.

Choosing and the price of the finished tank

It is necessary to choose a tank with consideration for the necessary capacity. There are very large, industrial units for 100-150 liters of LKM on sale, as well as small models that hold as little as 2 liters of paint. 20 liters of paint is typically the minimum productivity for devices, making this volume the most widely used and universal. Although a larger device can be used for more challenging tasks, its cost increases with its size.

When making a purchase, you should consider the following:

  • material of the case of the spray -enchanting tank;
  • type of mixing – manual, mechanized;
  • general dimensions of the device, the convenience of its movement and weight;
  • nominal and maximum pressure when air supply;
  • performance, l/hour/min;
  • paint consumption speed, kg/h;
  • The maximum distance of the end of the paint, m.

In stores, spray-off tanks typically cost between 10,000 and 20,000 rubles for domestic models and between 30,000 and 50,000 rubles for imported models. Certain products come with extra features, like the ability to heat paint before serving, which makes them even more expensive. The most widely used are Italian Walmec devices, domestic SO-12A brands tanks, and Caliber BK-10 and BK-20.

Painting requires the use of a spraying tank because it guarantees a uniform and fluid paint application while requiring less time and effort than conventional techniques. It makes it possible to control the paint flow more effectively and lowers the possibility of drips and uneven coverage. Large surfaces and intricate work benefit greatly from the use of this tool, which produces a polished finish with little waste.

Tank service

During operation, you must ensure that the tank is operating in accordance with the recommended parameters in order for it to function properly. For instance, the paint’s viscosity is 1.88 ° E, or 10.3, and the hose’s maximum length should not exceed 5.5 m. Because of thermal expansion, the material in the LKM expands, leaving about 25% of the container empty when the tank is filled to capacity.

While the machine is operating, the second specialist maintains the tank by continuously checking the pressure and, in the absence of automation, by mixing the paint. The employee also modifies the submitted composition’s consumption and assesses the paint’s sealing capacity’s dependability. The quality of the final coating will deteriorate if you do not strictly regulate every aspect of the device.

In order to ensure the safety of using a spray-enhanced tank, it is crucial to:

  • Before maintenance, dump the pressure to the atmospheric, disconnect the hose from the compressor;
  • regularly check the operation of the safety valve;
  • find out the fixation fortress of all elements of the device;
  • control the work of the manometer;
  • observe the condition of the filter;
  • After completing the staining process, rinse hoses, container, solvent control elements.

When painting, there are several benefits to using a spraying tank that improve the productivity and caliber of your work. It makes it possible to apply paint more consistently and evenly, which lowers the possibility of streaks and uneven coverage. This is particularly significant for intricate shapes or large surfaces where a consistent finish is essential.

Painting is also expedited by the spraying tank. You can work more quickly and avoid having to stop frequently to restock on paint when there is an endless supply available. This guarantees a more efficient workflow and saves time, resulting in a more polished output.

Furthermore, spraying tanks reduce the amount of paint wasted. They ensure that paint is applied exactly where it is needed and give you better control over how much paint is used. This efficiency is more cost-effective and environmentally benign.

A spraying tank is a very useful tool for people who work in professional settings or on large-scale projects. It increases output and makes it possible for painters to complete a job with greater quality and less effort. Purchasing a spraying tank can greatly enhance both the painting process and the final product.
