How to make a foam generator for a car wash from improvised things with your own hands. How to make a car shampoo for non-contact washing with your own hands Do-it-yourself foamer for washing interskol

Hey! Foam generators of various designs are increasingly used in our daily life. On the other hand, almost every vehicle owner strives to keep it clean and tidy, despite weather... It is no coincidence that a DIY foam generator has become the topic of the current publication. Yes, yes, there is no need to purchase this equipment for a lot of money, because you can assemble it yourself much cheaper. Next, I'll talk about how to do this.

A non-contact car wash causes less damage to the paintwork of the car and we talked about earlier. And to increase the efficiency of its use, it is necessary to use a foam-generating device. First, why exactly foam? This composition boasts of its soft and loyal effect on the body and paintwork - this is extremely important when it comes to contactless washing. At the same time, it is able to qualitatively protect metal, plastic, glass from the most resistant and corrosive types of pollution. Thus, the car foam generator became popular due to its complex effect.

The design of such equipment usually includes several basic elements:

  • directly the container (cylinder) filled with compressed air;
  • a device that provides a feed (such as a gun, a spray gun);
  • fittings, hoses, etc.

A little about the principle of work

So that you understand how a foam generator works from a sprayer or even a factory type. Compressed air is supplied to the working container under pressure, due to which the foaming process begins. Further, this mixture must pass through the so-called "foam tablet".

It is she who starts the process of active foaming, as a result of which a stable composition is formed, which is needed for cleaning a car or other object. Due to the presence of plates in the regulator, placed at a special angle, the washer can adjust the feeding power and the area of ​​\ u200b \ u200bthe foam composition.

How to make equipment with your own hands

Now we will talk about the most ingenious equipment, which is quite enough for washing in a domestic environment. But before it is necessary it is his high-quality washing.

First, we will prepare the toolkit - it can be found in almost any garage or home workshop: pliers, a set of keys, a knife, a tape measure, a grinder.

Take a 0.5-meter piece as a spray metal-plastic pipe with a diameter of 1 inch. We also need a sponge like a mesh, which is used for washing dishes and other cases - we push it as much as possible into the pipe. It is used for foaming. We plug the other side of the tube with a plug, then a tee and a tap for opening.

The compressed air produced by the compressor will be supplied through the faucet. The opposite end of the pipe is connected to the foam hose. It can be equipped with a large mesh filter element. Next, we need to find a container in which the foaming liquid will be located. The material does not play a primary role - if only it is able to withstand the working pressure (some craftsmen take as a basis the tank from a former fire extinguisher, see the video).

Factory version - manufacturing differences

You can assemble an alternative generator, which will be closer in functionality to the factory designs. We take a hose or tube, fill it with a foam rubber sponge, which is pulled with a thin wire (fishing line) for secure fixation. We put a mesh stopper at one end so that the material does not penetrate into the nozzle.

Air must be supplied from the bottom of the receiver - for this the tube must be of the appropriate length. To regulate the power of the jet, an adapter cuts into the tank. The foam tablet can be placed at the exit point of the finished composition. Next, the air supply hose is connected to the compressor.

We check the tightness of all connections, in particular, threaded ones. To be able to control the pressure, it makes sense to embed a pressure gauge into the structure. Thus, a conventional compressor for pumping up and controlling tire pressure will help to build a foam generator close to the factory one. A handle with a nozzle or a pistol is purchased in the gardening departments of supermarkets and department stores. Then it all depends on the user's imagination and his ability to handle the tools at hand.

In principle, the most inexpensive foaming nozzle from Karcher will cost from 1,500 rubles and more. However, you can save even these funds by assembling a simple structure on your own and with improvised means. Some even manage to make a sink from a garden sprayer. Today you could be convinced of this. Using such a device, you can even wash the engine and the inflated space, naturally observing

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

The main components of this equipment are:

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

Large equipment with a large balloon capacity can be mounted on the transfer cart for easy movement.

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

The foam transformer cannot work on its own. The normal operating pressure for the foam generator is 5 - 6 bar. For control, a pressure gauge is installed in the tank, pressure control is performed by the existing pressure regulator.

Purpose and principle of operation

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

The active composition of the foam contributes to 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 lattice with a small mesh, closed in several layers and made of corrosion-resistant wire. It is defined in a housing mounted on a cylinder. And it is connected to the supply hose. This tablet ensures that the fine grain foam is delivered at a high frequency.

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

Do-it-yourself washing machine

Considering the hardware system, you will notice that the main component is an expandable 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 rework 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:

  • it is necessary to disconnect the valve and the connecting hose from the sprayer;
  • insert bushings into the holes and fix them with nuts on both sides and with gaskets;
  • install a pipe on one of the actuators so that it almost reaches the bottom of the tank, a check valve and an air supply connection;
  • on the second disk adapter;
  • the pump must be cushioned as needed.

It remains only to connect the hose to the outlet. Thus, the product is ready. The device is not as convenient to work with as with the factory equipment, but it is acceptable.

For washing you will need:

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

Among the disadvantages of the foam generator, one can single out the need for periodic pumping of pressure, since the controller does not have a regulator. There is also no exhaust flow regulation.

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

This method is even easier than the previous one. It makes it possible to collect a foam source for cleaning from appliances with minimal cost. Not much is needed for the product. It is not difficult to make a foaming agent for washing with your own hands.

This only requires:

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

It is necessary to take a tube 70 cm long. Both ends must be closed with special plugs. The plugs must be fitted over the threaded holes.

On one of the caps of the foam generator, you need to put an adapter in the form of the letter T. On the second, fix the connection. Connect the hoses to the 2 outlets of the T-adapter. Do not forget about the stopcocks.

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

In case include homemade foam generator for washing a car for the first time, you need to supply plain water with a small amount of dye. This will help identify weaknesses in the structure, if any.

Alternative tank view

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

An article on how you can make a car shampoo with your own hands - recipes, ingredients, nuances of work. At the end of the article - a video about what will happen if you wash the car "Fairy".


The content of the article:

In the warm season, a private car has to be washed more often. For this purpose, they call in at a car wash or to the nearest reservoir. But you can clean it yourself at minimal cost if you prepare the detergent yourself.


It is important for the car owner to keep their vehicle clean and tidy. Until some time ago, many drivers used tap water and an ordinary rag from an old T-shirt for washing. Nowadays, such methods are not suitable for expensive and, in a certain sense, "delicate" cars. To get a high-quality and long-lasting effect, it is recommended to comply with the following conditions:
  • Do not wash your car in the wind or in direct sunlight;
  • Use appropriate detergents;
  • Follow the sequence of actions.
Cleanliness experts advise against using household cleaning products that are intended for washing laundry.

There is a wide range of car wash shampoos on the market today. Every interested car owner has the opportunity to purchase for regular use car shampoos of the following consistency:

  • Liquid;
  • Pasty;
  • Powder.
The liquid soap is already ready for use, and the powder or paste must be diluted in water.

However, if there is no way to get to the outlet, then you can, without much doubt, prepare the detergent mixture at home or in the garage. The main thing is that you have the right dishes and basic ingredients on hand.


I must say right away that it is folk remedy does not cope with serious pollution. Bituminous spots on the body cannot be washed completely. The soap solution is good for use after driving on dirt roads, when the car is simply covered with dust. For manufacturing, you will need a briquette of laundry soap and warm water.

First you need to shave or cut the soap into small wedges. Then dissolve it in water, stirring or shaking vigorously. One quarter of the briquette will be enough for three liters of water. You can take half. When the solution is ready, you can start the procedure.


Soap solution is used for both contact and non-contact washing. In the first case, homemade shampoo is poured into a bucket and applied to the car body with a rag. In this case, foam should form intensively. After a few minutes, it is easily washed off with clean water. Places with sticky dirt are carefully brushed so as not to damage the paintwork. Instead of a rag with a non-contact procedure, a simple liquid spray is used. It is convenient to use a spray bottle that sells glass cleaner. Or you can buy a suitable tank in advance at a hardware store.


The practice of recent years shows that the wrongly chosen shampoo contributes to the destruction of the paintwork of the machine. But this is a long process, and if you wash the car a couple of times with a product that has come to hand, nothing terrible will happen. A high-quality car shampoo is easy to make with your own hands from the following ingredients:
  • Caustic soda;
  • OEDP acid;
  • Surface-active substance.
All components dissolve in plain water from the tap in the order shown in the list. One liter of water is taken 200 g of caustic soda, 250 g of acid and surfactant.

During preparation, after adding each substance, the solution must be thoroughly mixed. This is done with a mixer or small spatula. Caustic soda and HEDP acid are used in boiler houses and heating networks for descaling. The drugs are readily available in stores.


The easiest surfactant to find is AC-1. As a result of mixing all the components, a concentrated shampoo for washing cars is obtained. When used, the concentrate is diluted with water in a 1: 1 ratio.


Shampoos for non-contact cleaning have a lower viscosity and higher chemical activity. Within 5-10 minutes, the foam retains the specified properties. During this time, the dirt dissolves and is absorbed by the detergent composition, after which the dirty foam is removed from the surface with a stream of water.

To obtain a shampoo with such parameters, isopropyl alcohol and sodium cumene sulfonate are added to recipe number 2. Only 2% by volume of water. Isopropyl alcohol, or in other words, butyl glycol, is a catalyst that accelerates the foaming process. Cumene sulfonate - on the contrary, an inhibitor that slows down the settling and drying of the foam.


When mixing caustic soda and HEDP acid, heat is generated. You should not be afraid of this - the process is proceeding normally. It is not necessary to wait until the solution cools down, the surfactant AC-1 can be added without fear. Once again, it must be reminded that it is very important to thoroughly stir the composition after adding the next component. When the mixture is uniform in color, the shampoo concentrate is ready.

Practice shows that it is not worth storing such a product for more than a month. After this period, the detergent mixture begins to lose its quality. The shelf life can be extended by adding preservatives to the shampoo, but this is a different, more complex technology.


Cars domestic production like our tanks, they are not afraid of dirt. However, vigilant traffic police officers will not miss the opportunity to talk to the owner of the "dirty".

Road users also glance disapprovingly at the unwashed car.

Given these and similar circumstances, the driver it is advisable to have a suitable detergent in the glove compartment or trunk... Some car owners use regular hair shampoo to wash their car "hastily". They choose and buy a cheap product that brings quite tolerable results. The main thing is no additional ingredients add to the shampoo, as advised by "sophisticated experts", is not necessary.

Another ready-made product that is used instead of car shampoo even in commercial car washes is liquid laundry soap. It even removes bitumen stains on the vehicle's paintwork. For Lada, a 500 ml bottle is enough for two washes. The soap is diluted with water in the same proportion as the shampoo from the store. Retail chains offer to buy a 5 liter canister, and then there will be enough soap for the entire warm season.


The car owner has to monitor the cleanliness of his vehicle, regardless of desire or mood. Experienced drivers know that a freshly washed car improves its aerodynamic parameters. The air resistance decreases, and the fuel consumption per unit distance decreases.

This does not mean that the car should be “bathed” every other day or every day. It is advisable to clearly define the conditions and time when you need to start up your own car shampoo. It is important to wash your car according to the rules, so that the negative consequences are minimal or absent altogether.

On the shelf next to the shampoo canister, it is advisable to have the following accessories:

  • Hard and soft brush;
  • Microfiber cloths;
  • Cotton towels.
This list can be expanded. The main thing when washing your car is to complete the procedure correctly. Otherwise, all efforts and car shampoo will be wasted. Thoroughly wipe the surface of the body and glass so that no streaks remain.

It is imperative to check whether water has entered the interior. Often, some moisture builds up under the rug in the driver's seat. Over time, a corrosion center will necessarily form in this place. For half an hour, you can leave the car with the doors open to ventilate the cabin.

Video about what will happen if you wash the car "Fairy":

A touchless car wash is still considered a luxury for many car enthusiasts. During a crisis, spending 200-300 rubles to wash your iron horse is not the most practical solution.

Of course, you can buy a mini car wash, but it the price often reaches 10-15 thousand rubles... But there is a way out! Assemble your own washing foam maker. Moreover, its cost will be several times lower than if you bought a finished product.

The only expensive element of a foam generator for washing is the compressor, which is responsible for air injection. But it can be purchased on the secondary market for relatively little money (low-power model).

Purpose and principle of operation

Before you start assembling a foam generator for washing with your own hands, you need to understand the principle of its operation. The device has two functions: it creates foam and distributes it evenly over the entire surface of the car.

The jet of water passes through a special solution in the tank and mixes with the air jet. The result is foam. However, this is not the whole process. Inside the foam generator for washing, the blown substance must obtain the required density. To do this, soapy water is supplied to a special foaming tablet.

Important! The expandable tablet is corrosion-resistant, so you don't have to worry about its safety.

The adjustment plates are arranged in parallel. As a result, the fluid flow becomes flat. The long hose of the device allows you to comfortably wash your car with high quality. Since everything is more or less clear with the principle of operation, you can start assembling a foam generator for washing with your own hands.

Comment! As detergent the foam generator uses a special car shampoo.

Assembly methods

There are many methods for assembling a foam generator for do-it-yourself washing. In most cases, the components that are in any garage are enough to create this device.

Drawings of a foam generator for washing are not particularly complex. It is not surprising that most car owners decide to make this unit with their own hands.

Simple and fast

Attention! First, you need to buy a compressor.

It is most convenient to make a foam generator for washing with your own hands from a sprayer. The design of this device is almost identical to the factory tank, except, of course, some differences.

Important! Please note that the walls of the sprayer must be thick enough to withstand a pressure of 5 atmospheres.

Remove the valve and the fitting from the sprayer. As a result, you should get two through holes. The hand pump must be disassembled and shut off. Next, you will need the following elements to create an effective foam generator:

  • two half-inch squeegees and four nuts;
  • check valve;
  • air fitting;
  • barrel of pipe connection;
  • foam tablet;
  • hose adapter;
  • gaskets.

Screw the squeegees into the plastic tank and tighten them with the nuts. Do not forget to use spacers when doing this. They are needed for tightness. Choose one of the squeegees and screw on the check valve with the fitting. Place the barrel on the other to connect with the tablet fixed inside. That's it, the foam generator for washing is made by hand.

Important! A tube must be attached to the squeegee through which air is supplied. It is necessary that the air enters from below. Due to this, the liquid will foam.

True, you still have to tinker a little with the hose, but it won't take long. Just attach a garden sprayer to the end of it.

After the foam generator for washing with your own hands is made, you need to pour water and a special cleaning agent inside. The proportion is 10 to 1. During operation, the neck must be tightly tightened. Turn on air supply and activate sprayer. Average consumption of car shampoo is 20-50 grams per wash.

Important! The compressor must create a pressure in the range of 4-5 atmospheres.

As you can see, the device of a steam generator for washing from a garden sprayer is not particularly complicated. On average, the unit can be assembled in 2-2.5 hours.

How to make a foam generator from a plastic canister

This method is even simpler than the previous one. It allows you to assemble a foam generator for washing from available tools at minimal cost. To do this, you will need:

Take a 70 cm long tube. Fill it with different sizes of fishing line. As a result, a homemade mesh should form. Both ends are closed with special plugs. The plugs must have threaded holes.

Install the T-shaped adapter on one of the foam generator plugs. On the second, fasten the fitting. Connect the hoses to the two outlets of the T-piece. In this case, do not forget about the stopcocks.

One hose of the foam generator for washing will lead to the reservoir with the foam liquid (canister), the other to the compressor. This method allows you to assemble a foam generator with your own hands at home with minimal cost.

Important! The first time you turn on your hand-made washing steam generator, fill the tank with plain water with a little dye. This will determine weak spots constructions, if any.

Alternative type of detergent reservoir

When assembling a foam generator for do-it-yourself washing, the selection of the correct tank is of particular importance. The simplest techniques have been described above. Nevertheless, a propane cylinder is considered the best blank for a tank. It can withstand almost any pressure. With it, you can implement strong flow without fear of damaging the structure.

To create a full-fledged tank from a propane cylinder, you will have to apply welding. First, weld all the old holes and make two new ones: one at the bottom point of the end, the second in the middle. Weld pipes with fittings to them.

You can use both collet adapters and couplings. The main thing is that this structural element of the self-made foam generator for washing can withstand the pressure generated by the compressor.

For greater convenience, a hatch can be made on top of the foam generator. To make it convenient to refill the washing liquid through it. The main thing is not to forget about the seal. The container must be completely sealed.

The lower tank connection connects directly to the compressor, the upper one connects to the spray gun. As you can see, the principle of connecting a tank from a propane cylinder is the same as that of a spray. But the service life and reliability are many times higher.

How to save on materials

First, you don't have to buy new components. Secondly, practice shows that half of the necessary spare parts for assembling a foam generator with your own hands can be found in the garage.

Nevertheless, even a used compressor will cost at least 2-3 thousand rubles. But there is one trick here. This part can be removed from an old truck. On the Internet bulletin boards, you can find hundreds of offers from tractor owners selling their cars for spare parts.

The compressor of the required power is equipped with a ZIL-130... Most of these machines have been in dumpsters for a long time. Therefore, you can take the part you need for a purely symbolic fee to the watchman, or even free of charge.

Please check the unit carefully before purchasing. It should be free of oil drips and other defects. Otherwise it is dangerous to work with the compressor. Even if you manage to start a self-made foam generator for washing, but equipped with a defective compressor - 1-2 cleanings and the unit will fail.

Important! Above, a method has already been presented on how to make a grid for bubbles with your own hands. Then the fishing line was used. You can just as well use a foam sponge or a plastic synthetic body washcloth.

Alternative methods of forming a nebulizer

If you do not have fishing line available, you can make a foam generator spray for washing with your own hands from a synthetic sponge. Just cut out the piece you want and place it in the tube. Make sure it is securely fastened. It is necessary that he does not crumple under strong pressure.

Important! Your main task when creating a nebulizer is to securely hold the filter, which will create small bubbles with a high density.

How to make your device more portable

The design of the washing foam generator can be upgraded. Naturally, all operations are easily done by hand. You will need a small aerosol canister and a pressure washer attachment.

The filler tube is replaced by a nozzle, and the propane can is replaced by a canister for an aerosol gun (you can just as well use a sprayer). The weight of the structure is reduced many times. The addition of a welded frame and wheels makes the foam generator completely portable.

Outcomes

Making a DIY foam maker takes time and effort. But the result fully pays for all the costs. Now every car wash will be practically free for you.

Modern equipment for construction works striking in its variety. Manufacturers of equipment are trying every day to develop more and more advanced devices designed for a wide range of jobs. However, it should be noted that in most cases, the purchase of equipment for construction work is a very costly event in financial terms. Meanwhile, a rare builder is ready to question the possibility of full provision of construction activities only because of the need to pay for the purchase of new equipment. In addition, not only the purchase, but even the temporary lease of construction equipment can be too significant a financial loss. Fortunately, a good craftsman can even assemble a foam generator for.

We study the design features of the device

As you know, self-made foam concrete of various categories is very widely used in the modern construction industry. The popularity of these materials is quite justified, because they have a fairly wide range of positive characteristics, which, however, practically does not affect their cost. In order to deal with design features self-made foam generators, it is worth studying the properties and components of the material that must be obtained in the end. In this case, of course, we are talking about foam concrete, which is traditionally made from the following set of components:

  • foaming agent;
  • cement;
  • sand;
  • water.


Foam concrete production scheme: 1 - a container for a foaming agent solution, 2 - a service platform, 3 - a compressor, 4 - a foam generator, 5 - a mixer, 6 - a pressure hose, 7 - tiered molds

It is worth noting that the production of foam blocks with your own hands is a very financially justified event. The cost of such a building material is lower than that of its counterparts on the domestic market. This is primarily due to the fact that the manufacturing technology of factory analogs of foam concrete is significantly higher. If we talk about the price that will have to be paid for a standard set of components for the production of building material, it must be said that the most significant expenses are foreseen in the purchase of cement. The rest of the components in the total amount will not exceed the price of the required amount of concrete.

How does the installation work?

Modern experts have tried to develop the simplest possible technology for assembling this equipment at home. In order to assemble a high-quality and reliable device, it is necessary to understand the principle by which it works. Actually, with the help of this device, foam is produced, which then forms the basis of foam concrete. The production unit traditionally consists of three different modules, which ensure the well-coordinated operation of the entire system and the implementation of its main functions by the machine. This is about:

  • modules that produce foam, as well as transport it. With the help of this module, it is possible to obtain foam;
  • a control element, with the help of which automated dosing of the product is provided.


A pre-prepared concrete solution is launched into the foam generator, which, under the influence of a certain pressure, is converted into foam concrete, pre-mixing with air. As practice shows, equipment of this type can be not only inexpensive, but also very productive. So, it is quite possible to build a unit capable of producing about five hundred liters of material per minute.

For a foam generator with your own hands, you can also make a concrete mixer, which is a tool that works in conjunction with this machine. However, it can be purchased in advance in the store. In addition, in some cases, a concrete mixer can be easily replaced with the most ordinary shovel or other convenient tool for the user, designed for mixing mixtures manually. One way or another, the concrete mixer itself is intended for making a mixture, that is, for mixing the above-mentioned material components.

We start production of the production unit

Before proceeding with the direct assembly of the equipment, you must first prepare detail drawing future car. Remember that it is necessary to make a foam generator for foam concrete at the same time simple and, of course, reliable design with maximum performance. The foam produced on the unit must be of high quality and sufficiently dense, otherwise the end result, the building material, cannot be used in the construction of buildings.

The foam generator circuit consists of control valves that set a certain density of the foam produced, as well as locking mechanisms that shut off the system if necessary. Thus, this homemade installation purely constructively works according to the principle known in technical sciences - pair valves. With the help of control valves, in the initial case of device operation, it is necessary to set the desired density of the foam to be produced. In the future, the owner of the device will need to adjust exclusively the shut-off valves.

The following components of the unit must be applied to the drawings:

  • turbulent mixing chamber;
  • nozzle or washer jet;
  • foam entry and exit points;
  • foam cartridge.

So, the turbulent mixing chamber is one of the key components of the machine. It is in this place that the previously prepared solution is immersed. In the chamber, the mixture is properly mixed and then, under the influence of a certain pressure, it passes through a double-truncated nozzle. At the moment of entering the system, the solution used under pressure is significantly compressed, and at the moment of exiting the car, on the contrary, it expands. In the case of expansion of the mixture, the speed of its movement increases significantly. At the exit from the truncated nozzle, the concrete solution enters the foam cartridge, where it becomes a foamy substance.

It should be noted that if the equipment is planned to be used temporarily, and its high performance is not extremely necessary, then the aval nozzle can be replaced with a washer-jet.

Assembling the unit: a beginner's guide

When deciding to build your own foam generator, take care of purchasing the following set of materials, as well as tools in advance:

  • metal sheets;
  • hoses;
  • pipe;
  • welding;
  • pump;
  • compressor;
  • adjustable valves, as well as their shut-off counterparts.


The first step is to assemble the vessel, which will be supplied in the required proportions concrete mix and air. Any iron container, the shape of which is close to cylindrical, is perfect for a tank for this purpose. In order to ensure a continuous supply of raw materials to the machine, you need to install submersible pump and hose. Another hose will supply compressed air to the structure of the foam generator. Using a special valve, it will be possible to adjust the pressure inside the structure. For example, if you want to increase the pressure level in the foam generator, then the valve must be closed.

The Laval nozzle is usually installed separately in the unit body. In addition, one must not forget to place a channel in the structure, which will expand and clamp in certain places. The foam cartridge is the closing element of the system, but its presence is perhaps the most important in the entire structure. This is due to the fact that foaming occurs precisely in it. In order to create foam in the foam cartridge, it must be filled with the most ordinary dishwashing devices - hedgehogs or nets. Drawings prepared in advance by specialists perfectly illustrate the types of connections in the structure, the location of its elements.

The nuances of assembly work

There are no assembly options for any device that do not imply specific features. Due to the specifics of the construction industry, self-production equipment for production building materials has a very significant specificity. So, answering the question of how to make a foam generator with your own hands, they name the following requirements:

  • the inlet diameter of the nozzle and its depth should be no more than thirty millimeters and be related in a one-to-one ratio;
  • the proportion of three to one is suitable for the ratio of the dimensions of the depth of the Lamal nozzle and its outlet diameter;
  • the center hole should be ten millimeters in diameter.

It should be borne in mind that in the case when you want to achieve an equipment performance indicator of the order of two hundred liters per minute, you need to select the appropriate dimensions of the foam cartridge. So, its diameter should vary in the range from 30 to 40 millimeters, and the length should be limited to indicators from 600 to 800 min.

Foam cartridge deserves special attention. For its manufacture, it is worth choosing not a spiral, but a wire mesh. With regard to filling, it is worth giving preference to stacks made of stainless steel. They, like a filter for the release of foam from the structure, can be bought in a regular store in advance. The body of the foam cartridge must be tightly filled with nets, and a ruff with a washer must be installed at its outlet. The ruff may not be installed, however, in this case, splashing of the product at the exit from the structure cannot be avoided. In addition, this will not in the best way affect the operational life of the entire structure. Assembling the foam generator, provided that the average level is theoretically savvy, will not be difficult, and the resulting unit will serve for a long time and with high quality.
