Homemade foam generator for car wash drawing. How to make a foam generator for car washing using improvised materials with your own hands? Homemade unit from an old sprayer

A foam generator is a device that is actively used in many areas. For example, car owners use it for non-contact car washing. The main task of the device is to form foam by creating pressure. Buying such a device for use is the desire of many, but the foam generator is very expensive, and not everyone can afford it. It’s another matter if you make a foam generator with your own hands.

Structurally, the foam generator is very similar to a conventional sprayer; the basic circuit is almost identical. But there is one caveat: the foam generator is high-pressure equipment.

The main components of this equipment are:

cylinder (from 25 to 100 l);
mixer;
a gun;
hose.

Large size equipment with large capacity balloon can be installed on the transfer cart to ensure easy movement.

Since the equipment operates under high pressure, the cylinders are made of stainless steel or metal with an integral anti-corrosion coating. In some industrial modifications, a straight ruler is installed on the cylinder, which makes it possible to control the flow and timely filling.

The foam converter cannot work on its own. The norm is operating pressure for a foam generator 5 - 6 bar. For monitoring, a pressure gauge is installed in the tank; pressure monitoring is carried out by the existing pressure regulator.

Purpose and principle of operation

Foam sprayers are very popular devices. They are used at technological service stations, in the fire, pharmaceutical and food industries.

The active composition of the foam promotes excellent cleaning:

production equipment;
road transport;
premises after renovation;
swimming pools.

The action of the foam is aimed at cleaning the surface, removing dirt, and disinfecting.

The main component of the device is the so-called foaming tablet. In fact, this is a grille with a small mesh, closed in several layers and made of corrosion-resistant wire. It is defined in a housing mounted on the cylinder. And it is connected to the supply hose. This tablet guarantees the delivery of foam in a fine-grained fraction with a high frequency.

And then the foam goes into the gun, which is applied to the plane. This hand gun is equipped with a feed regulator, which makes it possible to set the jet parameters.

Do-it-yourself washing unit

Considering the equipment system, you can see that the main component is a foaming tablet, which can be purchased separately. This means that you can make a homemade foam generator without any problems. The easiest way to make a contactless device is to take an ordinary sprayer as a base and modify it a little.

Thus, you need:

stabilizer;
two half-inch drills and nuts for them;
check valve;
air duct;
foam and adapter;
metal tube.

It is worth considering one of simple designs foam generator, which can be made from improvised means. It is important to follow the instructions.

Work order:

you need to disconnect the valve and connecting hose from the sprayer;
insert bushings into the holes and secure them with nuts on both sides and with spacers;
install a pipe on one of the drives so that it almost reaches the bottom of the tank, a check valve and an air supply connection;
adapter on the second disk;
the pump must be damped as needed.

All that remains is to connect the hose to the outlet. Thus, the product is ready. Working with the device is not as convenient as with factory equipment, but acceptable.

For washing you will need:

fill the container 2/3 full with cleaning solution;
connect the compressor and supply air to the cylinder (it is important to monitor the pressure and not exceed the norm);
after opening the spray valve, the air squeezes out the solution, passes it through the tablet, and the output foam is of quite acceptable quality.

Among the disadvantages of the foam generator is the need to periodically pump pressure, since the controller does not have a regulator. There is also no regulation of exhaust flow.

But the described design can always be improved by installing optional equipment to eliminate shortcomings and improve the ease of use of the foam generator.

Apparatus made from a plastic canister

This method is even easier than the last one. It makes it possible to collect a source of foam for cleaning appliances at minimal cost. You don't need much for the product. It’s not difficult to make a foaming agent for washing with your own hands.

For this you only need:

set of wrenches;
Bulgarian;
gun;
plastic containers;
nozzles;
compressor;
flushing hoses.

You need to take a tube 70 cm long. Both ends must be blocked with special plugs. The plugs must be placed on the threaded holes.

On one of the plugs of the foam generator you need to place an adapter in the shape of the letter T. On the second, fix the connection. Connect the hoses to the 2 outlets of the T-adapter. Don't forget about shut-off valves.

One arm of the foam generator for washing will lead to a reservoir with liquid, and the other to the compressor. This kind of method makes it possible to create a generator at home with my own hands at the lowest cost.

If you turn on a homemade foam generator to wash a car for the first time, you need to supply plain water with a small amount of dye. This will help determine weak sides structures, if any.

Alternative tank view

When assembling a foam generator with your own hands, choosing the right tank is of particular importance. Simple ways were shown earlier. There is another option.

Making a foam generator for a car wash with your own hands is not difficult. To form a foam generator with your own hands for washing a car from a propane cylinder, you need to use welding. You need to weld all the old holes and make 2 new ones: one at the lower point of the end, the second in the middle. Weld pipes with fittings.

Both collet adapters and couplings can be used. The main thing is that this DIY component of the foam generator installation can withstand the pressure generated by the compressor.

For maximum convenience, the hatch can be made for a foam generator. The container must be completely airtight. The bottom connection of the tank is connected directly to the compressor, the top connection is connected to the atomizer. As you can see, the principle of turning on a tank from a propane cylinder is the same. However, the operating period and reliability are many times higher.

Conclusion

Creating a device similar to a foam generator for washing a Karcher with your own hands takes time and effort. However, the result fully compensates for all costs. Now any car wash will be practically free.

Each car owner uses various car care products. Among the many types, the most common is car shampoo. Quality option allows you to make your car look beautiful appearance, clean from dirt and dust. Today we will look at how to create a car shampoo with your own hands, which will not contain harmful substances and chemicals.

Cosmetic treatment of a car is a rather responsible procedure that requires certain knowledge and skills. Let's explore which shampoo for contactless washing is more profitable to buy? Of course, car owners want their car to be in well-maintained condition, but not to suffer from negative influence chemicals that destroy paint.

Features of car shampoos

Using low-quality car shampoos can lead to such negative consequences, How:

Cloudiness of bodywork and glass.
Remains of dirt and grease stains.
Stains and stripes.

Incorrectly chosen cosmetics can lead to damage to the bodywork. Many car enthusiasts prefer to make car shampoos with their own hands. However, to give examples of various recipes, you need to know the features of car washes.

Car wash technologies

Today, there are two options for bringing your iron horse back to normal appearance:

Special car shampoo

Use car wash services.
Use detergents and wash the car yourself.

In any case, professional contactless car washing is necessary and irreplaceable. This is due to the following factors:

Foam is provided in large quantities.
You can easily wash away dirt, oil and other contaminants that car shampoo cannot remove.

Please note that there are several washing options: manual or touchless car wash.

Advantages of professional car care products

Using a foam generator

The use of professional branded cosmetics has a number of advantages. Their recipe, properties, foam and consistency combine perfectly with each other and make it possible to:

Ensure the highest quality cleaning of the car body, glass or headlights from dirt.
Cause minimal damage to the bodywork, as well as to all metal or plastic parts.

Types of car shampoos

All car shampoos are divided into the following types:

For contact washing, which is used for washing with a rag.
Contactless. Designed for washing using high water pressure.

There are various nozzles on the automotive market that are designed primarily for contactless washing. Their design, shape and quantity contribute to the formation of intense foam.

According to the recipe and consistency, car shampoos are:

Powdery, which must be dissolved in water until foam appears.
Paste-like, which are applied to the surface or dissolved in a small amount of water.
Liquid.

A gentle option - do-it-yourself car shampoo

If purchasing shampoo at a car dealership doesn’t suit you for some reason, you can learn how to make it yourself. To do this, you just need nothing: a bottle of high-quality shampoo, where its composition is indicated. The recipe is simple and clear. To create cosmetics we take the following steps:

We exclude all chemical components that are not always available in stores.
We make a list of elements that are most accessible.
We find the most common hair shampoo.
We add the necessary elements and get car shampoo for contactless washing.

This simple method is the safest and most inexpensive when compared with buying a ready-made mixture. You can do your own auto chemicals in no time, but you still get good foam.

Let's look at a detergent that you can make yourself from available ingredients. It contains substances from one of the following categories:

Natural base: animal or fish fat, vegetable oil, wax.
Synthetic materials: propylene, paraffins, ethylene.
Substances that reduce water hardness and increase fluidity detergent.
Formers, thanks to which the foam improves the quality of washing and increases the speed of removal of contaminants.
Various anti-corrosion additives that foam contains.

In addition, to make your car shampoo as similar as possible to the industrial shampoo found in stores, you can add some polishing or deodorizing ingredients to it.

The proportions of components are chosen by each car owner independently, through trial and error. After mixing the composition, you get a high-quality car shampoo that can be used for contact or contactless washing. In the first case, the solution is applied to contaminated surfaces with a brush, and in the second, it is filled into a foam generator, after which foam appears ()

How to properly use homemade car chemicals

There are no beneficial differences between homemade and homemade chemicals. Shampoo for contactless washing, which you prepare yourself, just needs to be diluted in water. Then we perform the following simple steps:

Apply shampoo and water to the car body with a washcloth, without rubbing too much.
We wait a couple of minutes for the shampoo to remove the dust.
Again, we wash off the shampoo with a brush, only now along with the dirt.

You can also polish your car, but not more than once a year. Doing this is somewhat more difficult and responsible, so it is better to buy high-quality cosmetics. After rinsing off the shampoo, just wipe the surface with a rag, which will get rid of unwanted marks on the body.

After preparing your own shampoo, you can immediately begin washing. Depending on the consistency, it is necessary to dilute it with water. It is better to add less car shampoo, as a high concentration may damage the coating.

Apply the diluted product carefully, shaking before foaming. After washing, be sure to use special wipes or a dry soft cloth.

Do not let the water dry out as this can cause a lot of streaking. Do not overuse chemicals that contain wax. In just a couple of days, from such treatment the body will be covered in dust, and it can only be washed at a specialized car wash.

Ignoring these tips can lead to destruction of the surface, as well as negative side effects. Contactless chemistry is the best way to clean your car and maintain its shine without any streaks or marks.

Contactless washing For many car owners it is a luxury, as it costs up to 300 rubles. Not everyone will allow themselves the next time they wash their car. Buy a mini-wash, spending up to 15 thousand rubles. Not many people solve it either.

But it is quite possible to afford a foam generator for washing with your own hands from a sprayer, spending minimal funds, by making it yourself from an old sprayer and several simple details. Such a foaming agent will provide constant, almost free, but fast and effective car washing at home.

Principle of operation

The main purpose of the foam generator is foam formation from shampoo and water, which after generation is evenly distributed over the surface.

The sprayer as a foam generator is based on mixing two foaming components under compressed air pressure and delivering foam to the surface.

In practice, this is realized by mixing water and detergent in a container, compressed air pushes the solution through foam tablet with the formation of dense active foam.

Necessary materials

For the future foam generator to operate efficiently, the purchase of expensive components, as well as the use of new parts and devices, is not necessary. When making a device with your own hands, you will need the following parts and materials:

container from a garden sprayer. Containers from sprayers, garden ones, as well as “Quasar” or “” models are suitable for this.

For these models, the pump or pump is dismantled;
pressure gauge with scale up to 10 atm;
nipple with a shut-off valve that allows air to flow in one direction; two 0.5-inch fittings with four nuts and gaskets;
valve that regulates the supply of foam;
metal tube and;
reinforced hose that can withstand pressure up to 8 atmospheres;
hose adapter;
clamps for connecting fittings with hoses;
foam tablet.

When selecting materials, the first step is to determine a container that can withstand pressure up to 6 atmospheres. Undamaged tank garden sprayer fits these requirements quite well. You can buy a foam tablet in a store or make it yourself.

The basis for the functioning of the foam generator from the Zhuk sprayer is a metal mesh, which can be easily made from a metal brush intended for washing dishes, or a tightly knitted lump of fishing line.

Safety precautions

When making a foam generator, you need to take into account that the container in the sprayer can withstand pressure up to 4-5 atm. When pumping air into it, be sure to monitor the pressure gauge reading or control the pressure with the relief valve.

Do not use the device for other purposes than for its intended purpose by pouring toxic or flammable substances into the container.

How to make a foam generator from a sprayer with your own hands? If you have previously made your own for a snow blower, made one, assembled it yourself, or for a walk-behind tractor, then it will not be difficult for you to make a foam generator yourself from a sprayer.

If the necessary parts and components are available, the foam generator is assembled in the following order:

in a sprayer container deleted hand pump and the holes are plugged;
a pair of 1.27 cm (0.5 inch) squeegees are installed in the upper part of the tank. The parts are fastened with nuts on both sides, and their tightness is achieved using gaskets;
A T-shaped adapter is placed on the air supply, a pressure gauge and a shut-off valve are placed on it, and a tube with a length slightly less than the height of the tank is attached inside. This is necessary so that air enters from below. Thanks to this, the liquid foams;
the second drive is designed to release foam. A tap, a foam tablet are installed on it, and for quick connection of the hose, it is easily removed. A metal tube is connected to the hose, and a nozzle or sprayer is connected to it. The foam generator is ready.

To automatically adjust the pressure in the tank, it would not hurt to install fittings for air injection control in the form of a valve that releases excess atmosphere.

This will free the operator from constantly monitoring the pressure gauge when pumping air, and guarantees the safety of the device, eliminating the possibility of the tank exploding under pressure.

Multifunctional high-quality motorcycle equipment. He will help you in those places where the snow is higher than the roof.

Motoblocks are a necessary tool for summer residents and farmers. get acquainted with the advantages of the Niva walk-behind tractor.

A home snow blower is a device with relatively low power for domestic use. - This is what you need.

After checking the reliability of all connections and the tightness of the tank, water is poured into it through the neck in an amount of 2/3 of the total volume and concentrated shampoo is added according to the instructions (usually up to 2 g/l of water). The neck is securely tightened and the outlet valve is closed.

By pump or compressor through a shut-off valve pump air to the required pressure. The hose with the nozzle is directed to the surface for applying foam and the tap is slowly opened. The density of application can be adjusted using a nozzle or nozzle.

Conclusion

Self-assembly foam generator It is done quite simply and does not require special knowledge and skills. The cost of its production will be 10-15 times lower, than the factory device. To do this, you need to draw up a product diagram and a sequential action plan, as well as correctly select all the necessary materials.

When assembling the device, safety requirements must be taken into account: since the foam generator tank operates under pressure, its permissible value is controlled with a pressure gauge, and all parts and connections must be functional and reliably assembled.

According to the latest census (2010), 26% of the population in Russia lives in rural areas. This is more than 37 million people. These Russians have many cars, but few or no car washes or facilities to visit them. In small towns the situation is similar. Most of these car owners prefer to wash their steel horses with a contactless car wash. high pressure"Kärcher" type.

With this washing option, the paintwork of the car body is not damaged. And the body is about half the cost of the car. Another reason for using this modern technology- small amount of water consumed. You can wash your car with almost two buckets of water.

About factory foam concentrates

If a car enthusiast bought a branded car wash for 8,000-40,000 rubles, then the box with it will almost certainly contain a high-quality foam generator. The cost of such a foamer is 1600-2000 rubles (depending on the model). Compatibility with sinks from other manufacturers is not guaranteed. The set of cheap car washes for 3000-8000 rubles also (purely nominally) contains a foam generator, but of such quality and performance that these devices are simply thrown away after the first attempt to use them for their intended purpose due to complete unsuitability. In the store, such a “dummy” steam generator costs 500-700 rubles.

Why foam shampoo?

This article is intended for owners who did not have effective foam generators in their kit. It is known that dense and abundant foam with the use of a special shampoo, applied to a dry body, significantly improves the quality of its washing.

An important parameter when washing is the exposure time of the foam to the dirt: if you wash off the shampoo too early, it will not have time to react and the dirt will not be completely removed. If you overexpose the foam, then when the composition dries, the dirt that has turned into foam will again fall onto the body in the form of a whitish sediment, which will inevitably lead to the formation of unsightly stains. Therefore, the foam must be on the surface paint coating body for about 4-5 minutes.

Taking into account the above, car enthusiasts are trying to make a foaming agent for washing with their own hands. Some of them are looking at large and expensive garden sprayers, spray guns, which, after conversion, can theoretically be used to spray shampoo, but the cost of such devices and the necessary air compressors, as well as other spare parts and components, often exceeds the cost of a branded pressure washer.

What and how to make a foaming agent for

Let's consider the cheapest and simpler option, which has worked well for many car owners. So, we make a foaming agent for washing with our own hands from a sprayer. We take an ordinary cheap hand-held garden sprayer, which looks approximately like the picture above, and consists of a pump, a container with a volume of 0.75 to 2 liters and a nozzle.

Its special nozzle allows you to spray the solution and adjust the spray pattern, but such a device will not create foam. Similar sprayers from different manufacturers have differences in size and design, so in this article we will look at the idea of conversion. It makes no sense to indicate specific sizes.

Sprayer - almost ready-made foam generator

Drawings of a foaming agent for washing with your own hands are very simple and do not present any difficulties. A little modification will allow you to use a store sprayer. To do this, you need to unscrew the plastic tip of the nozzle and place 2-3 cubic meters inside. see foam rubber, glass wool, foam tablet or the material of a regular metal grater used to wash dishes. The volume of these foaming elements is selected experimentally. In the upper part of the solution supply tube, use a needle to make a hole with a diameter of 0.3-0.5 mm to mix the liquid with air.

Upgrading the foaming agent for washing with your own hands to increase foam

This device can be upgraded to increase the volume of foam. Instead of a standard nozzle, you can make a new nozzle from two syringes with a volume of 5 mm. It is necessary to cut off approximately half of its length from one syringe, select the diameter of the washer, or cut off part of a cylindrical plastic tube from a standard nozzle to attach a new nozzle to the sprayer.

After this, it is necessary to connect the cut part and two syringes in any way, after placing the foaming material indicated above inside. It should be located closer to the sprayer outlet. The end of the syringe should remain empty to control the mixing of the foam.

If it is possible to purchase F110 nozzles (015, 02, 03, 04, 05) or flat-jet tips like HYPRO F80-06, then you need to cut off the extreme part of our homemade nozzle and install a flat-jet tip as a nozzle. By changing the tips you can achieve the desired spray pattern.

The air pressure needed for such a foam generator can be created using a foot pump by installing a nipple for a tubeless tire at the top of the tank. The pump should be pumped into the container without fanaticism, no more than 4 atmospheres, otherwise the spray tank will burst. Some sprayer models have a bypass valve. It needs to be adjusted to a pressure of 3.5-4 atmospheres.

After washing, do not forget to treat the body with liquid wax, since its varnish coating has a porous structure. These pores must be closed, blocking the path of corrosion. It’s easy to make such a foaming agent for washing with your own hands from a sprayer. It works for many car enthusiasts and suits them completely. The cost of such a device consists of the cost of the sprayer itself, a pair of syringes, and a car tire nipple and amounts to 300-400 rubles.

This article describes the features of their design, how to make it for washing, how to make a nozzle.

Car washing has a number of features, the main thing is not to damage the paintwork of the car. Modern car washes have low-quality guns that do not wash the car very well and often break. Gels are converted into foam using this device or dispensers. You can wash your car this way at home. It's worth making such a device yourself.

The structure of the device and its specifics

First, you should understand the functions and composition of the device if you want to assemble it. This is a metal tank with a capacity of up to 100 liters, consisting of a filler neck, a drain valve, 2 fittings, then a nozzle for spraying foam is attached. Tank, it's (2/3) filling up special means(10 ml) and 1 liter of water.

The special shampoo contains wax, which protects the car body. When the tank is full, the compressor starts working and compressed air comes out into the tank. The pressure must be at least 6 atmospheres. Also, water and product are supplied separately. It is diluted in a pistol; it is much more difficult to invent such a mixture yourself.

Foam forms in the tank and comes out through the filter, the sprayer is located in the nozzle, the pressure gauge monitors the pressure, and the water measuring tube monitors the degree of filling. Such a device helps a person; he does not interact with chemicals. The washing speed is about 20 minutes.

Pros of the device

no contact with the car body, prevents paint from darkening;
You can remove dirt in hard-to-reach areas;
a thin protective film is formed.

If you buy steam generators, they are expensive (depending on the capacity), so they are made with low pressure for home use.

Manufacturing Features

At self-production the cost will be about a couple of thousand rubles, and if you buy it, then about ten thousand rubles. Basic elements for making the device;

capacity;
reinforced hose;
pressure gauge;
clamp;
stop valve;
a tube.

We select a tank that can withstand up to 6 atmospheres; the volume should be up to 10 liters, so as not to add foam a second time.

Scheme if you make the nozzles yourself

Exist different types nozzles What tools will you need for this:

Roulette;
Bulgarian;
Spanners;
Pliers.

Prepare inch pipe at least one and a half meters, a washcloth. How to assemble - cut the pipe to at least 0.5 meters, the larger the pipe, the better quality foam. But don’t forget, a large pipe also requires a powerful compressor. Next, you need to hammer the pipe with a washcloth and cut a thread at the end, screw a tee onto one end, and filler on the other. Install a large filter, put a plug on one of the terminals of the tee, and connect a source of water with shampoo and a compressor to the remaining ones.

You can also adapt a regular garden sprayer and choose the right compressor. Remove the fitting and valve from it, remove the pump and install the plug. We will get 2 holes in the sprayer, screw in the clamps and secure them, install the gaskets. Screw a check valve with a fitting into one of the pipes and install a tank on the other.

When purchasing a foam sink, be sure to pay attention to the availability foam nozzle, if it doesn’t exist, then you’ll have to do it yourself, maybe this will be a joy for someone, and it will also save significant money. And all the materials can be found at home in the garage, so making a foam generator with your own hands is simple and profitable.
