How to cut a galloon grid along or across. Types of home -made filtering devices for wells

Do.it.yourself filter with your own hands plastic pipe 125 mm for a well

The main purpose of the filter is to clean water from mechanical impurities: sand, small particles of clay and limestone. The quality of the water and the durability of the well depend on it. Not for every well you need a filter. Whether it is needed or not. depends on the composition of the rock of the aquifer. Water can pass through various soils: shell.to.be, sand, clay, chalk, limestone and others.

In stable rocks, such as limestone or gravel, the filter can not be placed, enough holes or thin slots in a casing pipe. But if the aquifer lies in the sand or shell, then you can’t do without a filter.

Types of filters

There are two main options for the filter for the well: polypropylene and home-made filter of stainless grid of the galloon weaving brand P48 or P52 GOST 3187-76.

Such a filter has high mechanical strength and is not subject to corrosion, and also has a good filter speed. This filter is suitable for both gravel-teddy deposits and sand.

It has been widely used in shallow wells for water supply, where underground waters have great mineralization and aggressiveness. In fine.grained sands, a polypropylene filter is used with quartz or gravel sprinkling.

You can buy it in plumbing stores.

For its manufacture, the net of galloon weaving is most often used. Slots in it look like oblique triangles. Grains of sand, however, have the shape close to the square and close the holes in the grid. They will not work.

Иногда вместо нержавеющей сетки используют полимерную галунного плетения, например, польская SP12 или П52 производства. Such a grid is hard enough and designed to filter medium sand. But, as practice has shown, it can break at the time of the casing of the pipe into the well trunk.

To improve water purification from mechanical impurities, it is recommended to carry out gravelly sprinkling the casing. Gravel of a small fraction is poured into the space between the walls of the drilling trunk and the casing pipe.

Such a sleeping will act as an additional natural filter, which will affect the capacity of the mesh filter well, since it will be somewhat protected from clogging with sand.

Gravel sprinkling is mainly arranged if the aquifer is located in the fine.grained fraction of the breed.

How to make a stainless grid filter.

For its manufacture, a stainless grid of galloon weaving brand P48 or P52 is used. The smaller the number, the less often weaving and, therefore, is more free space between wires. The smaller the number, the greater the capacity of the grid and it is more difficult to score with clay sludge.

Galuna weaving grid.

We mark it.Cut off by marking.

The edges will be fastened with each other with the help of the so.called roofing lock. To create such a lock, it is necessary to bend the edge of the grid by about 2-3cm. This can be done with your hands without the use of tools.

We bend the edges for the formation of a roof lock.

Drill holes in the casing. Holes diameter approximately 16-20 mm. The distance between the holes in a row is 100-120mm. Total 5-6 rows in diameter of the pipe.

The rows of holes must be drilled with a displacement so that the holes are located in a checkerboard pattern.

There is a very important point here: there should not be too many holes, otherwise the pipe will lose its strength, and there should not be few, otherwise the filter throughput will be small.

On the casing, it is necessary to retreat 60cm from the edge and start the marking of the holes from this place. The unprofitable part of the pipe 50cm will act as a sump. Mechanical impurities will be collected in the sump, which managed to go through a filtered net. And another 10 cm will be busy with the filter winding.

The holes can be drilled with feathers on wood or a stepped drill for sheet metal. Before drilling, it is necessary to check so that the holes do not go beyond the working surface of the grid.

As a result, the holes should be drilled along the pipe at a length of not more than 1940 mm. Two cutting of the grid with a length of 1 m should completely block the holes in the pipe.

Some masters instead of holes with a diameter of 16-20mm drill a lot of holes with a diameter of 2-2.5mm. This option has the right to life, but then there should be really a lot of such small holes, since their area is very small. I will give an example: the area of ​​one hole with a diameter of 16mm is equal to the total area of ​​63 holes with a diameter of 2mm.

Holes can be replaced with thin slots. They can be made with an angular grinder (corner grinder).

Drill holes in the casing.

After drilling, the pipe and all holes must be cleaned of chips.

We wrap a stainless wire or fishing line for a trimmer with a diameter of 1 on a casing.7 to 2.3mm. This wire will create a distance between the net and the pipe. As a result, water will be filtered through the entire area of ​​the grid, and not just opposite the holes in the pipe.

We wrap a wire or fishing line for a trimmer for a pipe.

Install a stainless grid on the pipe. It turns around the pipe, and its edges are applied by means of a roof lock (the bend clings to the bend). Keep in mind one important point: its edge must completely cover the wound wire and protrude about 2 cm for it. Subsequently, this edge of the grid will be wrapped with wire from above.

We put on the net on the pipe and connect its edges into the roofing lock.

Squeeze the lock with pliers. Pupply should be done smoothly, without jerking. The net must tightly tighten the pipe.

The first clamp must be made about two centimeters from the edge of the grid. Then you need to squeeze the edge and continue to squeeze the entire grid. Such a compression sequence is necessary so that the mesh is more tightly adjacent to the pipe along its edge.

The device and purpose of the well filter

For the receipt of water from the well, a pump is required to be immersed in it. often it cannot regularly function in an environment in which large or small mechanical impurities are present. They negatively affect the device, reducing its resource, increasing the risk of breakdown. To avoid such consequences, the well is equipped with a filter.

All cleaning devices of this type have a similar design. They are installed in one- or multi-level systems. The main function of filters for a water well is to eliminate mechanical contaminants of different sizes. The main structural elements of the product are the following:

The presented products increase the service life of the well. Since you need to choose it correctly, you should consider 2 main options:

• With additional cleaning. A gap between the well pipe and a layer of soil is provided, which is covered with selected gravel. For the same purpose, marble baby is used. This arrangement extends the service life of the filter.
• Without an additional cleansing layer. The walls of the device and liquid have direct contact.

Such a device for cleaning water in the country prevents the siltation of the well.

How to understand which filter is needed for your well

The design of the filter on the well from the well is different. Its choice is influenced by the operating conditions and characteristics of the aquifer. If an artesian well is equipped on solid rocks or stable soils, then a coarse water cleaning filter is not required.

On clay soils or sand, it is better to mount a wire type or a cleaner equipped with a net: if the garbage is large. woven, and if small. with galloon weaving. The slotted well filter is suitable in cases where the aquifer does not differ in stability or contains a large amount of pebbles, turning on gravel.

Stainless grid of the Galuna Weave P-100, GOST 3187-76

To date, there are several methods of weaving nets that are used as water filters and others. substances. This is a sargot, linen and galloon method.

Linen grid is indicated by the letter “P”. It is made of stainless steel wire of the AISI 304 or 12x18N10T brand, by weaving “through one with wires duck”.

Sarge grid (C) is also made of steel, while it differs in a way of weaving wire. “after two”. They are used to dry bulk substances and solutions, water and air filtration.

The most popular of them is galloon weaving. Such a filter mesh can be made from various metal such as:

For the first time, such a grid was released in production back in the middle of the twentieth century specifically for filtering wells. It is weaved from several threads of wire, which twisting among themselves, form zero cells. The wire of the duck has a smaller diameter than the main wire, thus, the clearance will not be visible even if you put the net into light.

Galong weaving got its name from the methods of manufacturing galloon. stripes that are used in military forms.

The use of nets

The use of galloon nets is especially effective when installing holes with a diameter of 20 to 25 mm in a well barrel with a density of holes for each linear meter of pipe from 90 to 100 units.

Under this condition, the maximum possible filtering and performance of the well is achieved. Such a result is achieved with the redistribution of excess pressure in the well trunk through the oenic openings N the entire area of ​​the galloon grid.

With the correct conduct of penetration and the correct installation of the filter, the most effective option for operating the aquifer and the entire well is ensured.

The advantages of stainless grid

Low.carbon steel grids are demented to the formation of corrosion. The composition of non.ferrous metals includes expensive alloys, such as aluminum with copper or brass. For the manufacture of stainless nets, a special highly alloy steel is used.

It should be borne in mind that such nets can be produced in different sizes, and also have a different thickness. When choosing the material from which the galloon mesh is made, it is necessary to take into account its price, as well as resistance to corrosion. After all, if you purchase a low.carbon mesh over time, it will be covered with rust. When choosing a grid from non.ferrous metals, it will be necessary to pay a considerable amount for it.

The most suitable option remains stainless steel, which is cheaper than aluminum or copper wire at the same time has high strength, as well as the ability to withstand corrosion.

The stainless grid of galloon weaving, due to high quality and strength, is in great demand, both in industry and in agriculture. After all, stainless steel is characterized by a long service life. To destroy it or damage, it is necessary to make a lot of effort.

Advantages of galloon weaving nets

The main advantages of this type of weaving of nets include:

• Providing good filtration, regardless of the type of breed adjacent to the filter.
• Creation of the required volume of well design.
• Ensuring the maximum area in contact with the surface filter.
• High well, exceeding 40-50%, the well-stroke of the nets made by other types of weaving.
• The use of galloon weaving nets for wells guarantees the correct supply of water through the penetration to the well barrel.

How to choose a mesh filter for wells

It is important that after the installation of the unit pumping water, the sand does not damage the entire system. To select a suitable grid, you need to take bulk material from the layer under water, and let it through different samples of the grid. For example, if a particle of a bulk mixture is approximately equal to the cell, it will clog the filter. Smal particles will be able to pass through cells, and coarse.grained particles will be eliminated. Additionally, a grid protecting the pipe from large stones can be used. It has ducks in size from two to three centimeters.

If we are talking about water filters that are used in wells or wells, then you should choose, given the features of the aquifer. When choosing an inappropriate filter, water can slightly seep or have negative impurities.

For wells, different types of nets are used:

The main advantage of the stainless grid over everyone else is resistance to the aquatic environment.

Weave the grid with a galloon method from almost any material. But since filter nets are subjected to high mechanical loads, manufacturers are more inclined to choose a strong steel stainless wire. These are usually such brands as: 10x17n13M2T, 12X18N9T, 12X18N10T.

Having a relatively low cost, such wire is reliable and high.quality material even with prolonged operation.

Filters in which casing pipes are used are made of polyethylene pipes and stainless grids. The mesh for casing pipes extends the service life of this installation. Pipes for filters have insignificant weight, which allows you to easily transport them and install them.

Also, thanks to its smooth surface from the outer and inside, hydraulics improves during pumping water, and deposits or precipitation do not remain on the surface. Filters for casing pipes are great for installation in wells with water, because they are environmentally friendly and not dangerous for health.

Holey (oral) cleaning system

Due to the simplicity of the design, such a system is widely used. The main structural element is an ordinary peoral pipe, usually from PND. In industrial production samples as a material, stainless steel (stainless steel) can be used as a material. The main advantage is high efficiency at low cost. The main elements of this design are presented below.

Such a solution can be used both for the Abyssinian well and an artesian well, especially if the latter does not hit as a geyser, that is, it has a small pressure and/or an unstable layer of aquifer limestone.

How to make a homemade oenceous filter?

First of all, it is necessary to get a pipe of the corresponding diameter. The oil and exploration to this purpose is ideal for this purpose. In extreme cases, you can use a plastic product, provided that it is made of material safe for the human body.

We also need a drill with a drill of the corresponding diameter. It must be selected depending on the granulometric properties of the breed at the drilling site. Having prepared everything you need, you can proceed to the process of manufacturing a home.made system of rough water cleaning. The algorithm of actions is as follows:

• We measure the length under the sump. To do this, put the pipe horizontally and apply the appropriate marking. We note that at the following points:

• The site in which the holes will be drilled at least a quarter of the length of the pipe.
• The oenic zone should be located in such a way that when installing the filter, it falls on the place of water fence (water layer).

• We begin to drill holes, their lower row should be located at a distance of at least a meter from the edge. The location of the holes does not play a large role, but it will be correct if you place them in a checkerboard pattern. So it is better to control the distance between them. It should be in the range of 10.0-20.0 mm.

The holes can be made straight, but ideally the drill must be directed in such a way that an angle of 40 °.60 ° is formed, as shown in the figure

• Having completed the process of the penetration, it is necessary to clean the pipe, the easiest way to do this is if you install it vertically. After that, we clean the holes and the burr formed on them.
• At the final stage, the lower edge of the pipe set the plug. After that, the filter is ready for operation.

We draw attention to the fact that you can slightly increase the effectiveness of the design by closing the peeration zone with a net or organza.

Slit design

The main difference from the previous design is that the water fence is not carried out through holes, but specially cut.out cracks. This is positively reflected in the throughput. But this type has a significant drawback, which is expressed in the loss of the strength of the structure. In order to slightly reduce this factor, several whole areas are left in the oenic zone, they play the role of stiffness belts.

Making this type of structure is somewhat more difficult than a hole system. It is almost impossible to cut out uniform cracks by hand, this will require special equipment, ideally a milling machine.

The manufacturing algorithm does not make sense, since it does not particularly differ from the previous option. As for the size of the cracks, they depend on the breed. Their width is usually from 3.0 to 6.0 mm, length-25.0-80.0 mm. The location order can be a waist or chess. After the cracks are cut, they must be cleaned. Next, do not forget to remove the garbage from the pipe, how to do this described above.

Since this type of filter system is mainly used for sand wells, an additional external filter is required. For this purpose, a grid with galloon or square weaving is great. The width of the cells can be from 0.1 to 1.0 mm, it is selected depending on the structure of the sand.

Galuna type well grid: application, types

Well for filter

Private houses as source of water are equipped with wells. So that drinking water does not contain various impurities, treatment devices should be used when installing the source. For these purposes, a mesh for a well filter is suitable. Water enters the well due to the casing of the oenic type, which is buried at the water.bearing level. The pipe is equipped with holes on which the net is wound for filtering.

Varieties of material for the manufacture of mesh. To create a high.quality mesh filter in the well, you should determine the material that has suitable parameters for maximum liquid cleaning.

Various options for filters from the grid are distinguished, they differ in the type of material from which they are made.

General information

Metal mesh filtering devices

The borehole filter of galloon weaving, made of metal material, is considered a classic option for arranging a filter. Its quality has been tested for many decades. The material is durable, durable, you should choose a grid that has the optimal characteristics for operation.

Attention! Wapes with this type of weaving were invented in the fifties of the twentieth century. They were specially developed to clean water from large particles. The grid is a kind of fabric, it is based on a strong wire with zero.sized cells.

A distinctive property of the grid is the type of weaving: the base is made of material that has a great thickness than the main material. “duck”. Filter abilities are given due to special weaving. Cleaning occurs evenly, while the net has a high level of throughput.

Metal melting

The filter grid has many varieties, each type can be used in certain conditions:

one.Designation P 64, P 73 or more indicates that the net will cope with cleaning from sand, similar to dust, or in the form of fine grain. Marking shows that this material has the smallest cell diameter.

2.Designation P 60 is used for sources with impurities in the form of fine.grained sand, without dusty type.

3.P 56 is considered a universal option in the presence of source of small sand particles in the water, or medium diameter.

four.P 48 are suitable for sources with large circuits from sand.

What particles of sand are equated to a certain fraction

Many builders are interested in how sand is divided into fractions depending on the size of the grains of sand. The following components are distinguished:

one.Sand particles with diameter 0.ten.26 millimeters are attributed to the fraction of fine.grained sand. In the presence of dusty inclusions, the water also needs to be cleaned.

2.particle sizes 0.25. 0.5 millimeters are classified as an average fraction. This option is the most common.

3.particles 0.5. 1.0 millimeters and more belong to large sand. It is easiest to clean the water from him.

To independently measure the diameter of the grain of sand, you need a magnifying glass with millimeter paper. Board sand is poured on paper, particles are considered through the magnifying glass. What size sandstones prevail, sand and wells include sand.

Attention! A preferred option for a well is a stainless steel grid, the material is not corroded from water, without distinguishing any impurities into it.

When buying a grid, you should check the high quality of products so that the water is filtered well. For mesh, materials of increased strength, anticorrosive, during their manufacture, must be observed in GOST 3187. 76 during their manufacture. The marking of the wire is indicated on the marking.

Pros of metal filter nets

Metal grids have many positive characteristics. These include:

one.A wide range of materials that can be used in different soils.

2.high degree of filtration and capacity of the grid.

3.The nets are durable because the material is resistant to negative factors.

four.nets are not torn, resistant to deformation.

Attention! When saving the filter with your own hands, you can use a solder with tin, you cannot use lead, because it should not get into the water.

Synthetic mesh

The grids from this material appeared not so long ago, but became popular among buyers, because the material has special properties. These include:

one.Synthetic grid does not form blockages, siltation due to surface smoothness. Sand cannot cling to it.

2.resistant to corrosion, without secreting impurities into the liquid.

3.The filter grid has a high throughput indicator.

four.the grid costs less than metal products.

Synthetic materials are made according to TU, not GOST, like metal. Each enterprise develops its own production technology. It is better to purchase nets of famous brands.

Classification of mesh filters

There are several types of filter nets for wells and are classified according to different signs.

Types of nets by weaving method

• Standard. with square cells.
• Kiper. multilayer weaving.
• Galunna. with small and difficult cells. Such a grid allows you to get water of the highest quality.

In different types of soils, nets of all types of weaving can be used. Conventional and bicepor weaving is well suited for wells punctured in coarse.grained and gravel sand. Galuna weaving grid for wells- ideal with a medium and fine-grained rock.

Metal mesh filter

The canvas looks like a fabric, but it is made of thin metal wire. Such a filter began to be used several decades ago and he always justified himself. The metal mesh is very durable, durable and it has excellent throughput. Its cells are easy to clean from sand. Out of disadvantages. can be deformed during installation.

Since most metals are prone to corrosion from water, a stainless steel grid is the best option for wells for wells. In addition to its durability, it has another indisputable plus. it does not give the water a metallic taste and does not allocate any substances into it. Also, the filter’s borehole grid for casing pipes can be made of copper or brass.

Metal filter mesh on the casing of the well

Important: if you are going to mount the filter yourself, then it is better to use a tin solder for soldering. The use of lead is unacceptable if the water is used in food.

Synthetic materials grids

Carbon filament grids, polyamide or fiberglass appeared on the market relatively recently, but already managed to conquer home masters with their advantages:

• A very smooth surface, for which silt and sand do not cling.
• Not exposure to deformation and corrosion.
• The water has no extraneous taste.
• The highest throughput.
• Available price, which is several times lower than for metal nets.

If you have a plastic filter pipe, then the answer to the question of which grid to use for a well filter suggests itself. Of course, polymer! Although the metal is also suitable.

When buying a synthetic grid, choose trusted and popular manufacturers, because these products do not do it according to GOST, but by that. Unscrupulous manufacturers can grossly violate standard production standards.

In installation, the polymer mesh is completely simple. Its edges can be sewn elementary. But the thread needs to be selected appropriate so that the strength of the connection is not violated.

Tip: In order for protection from a synthetic grid to hold better, it must be wrapped on top with stainless wire.

Each type of grid has its own advantages and disadvantages. But you need to pay attention to the durability of the material, because the well is installed for not one year. Synthetics are not afraid of rot and rust, but it can easily tear. And the metal is more durable, but is more prone to corrosion.

The nets for filters wells are equipped with special markings to determine the desired type:

• The designations P-64, P-73 indicate that the mesh is intended to purify water from sand of small fraction. In this material the smallest filter cells.
• The P-60 labeling grid can be used to clean water from slightly larger grains of sands than the previous mesh filter for the well.
• P-56 is the most popular size. It is used for cleaning both from fine.grained sand, and from impurities of medium size.
• P-48 marking mesh captures only large sand.

Learn how to make a filter for a well with your own hands. We have described several possible options.

We talked about the advantages of plastic caissons in this material.

How to fasten a grid on a filter pipe?

Methods of mounting the filter grid depend on which material the filter pipe is made and the net itself is made. There are such mounting methods:

• Welding. This method is applicable to fix the steel mesh on a metal pipe. First, welded one edge of the grid, then it is tightly wrapped around the casing several times and fix the other edge with welding.
• Soldering. The principle of its action is practically no different from welding, but it can also be used for plastic pipes.
• Sewing. The edges of the grid are interconnected by a special thread or thick wire.
• Winding. A dense fishing line for a trimmer or wire is wound on top of the grid on top of the grid. Turns are made using force.

Making your own filter for a well is quite real and easy. The most important thing is confidence in one’s own strengths and the correct selection of the necessary version of the material. If you clearly follow all the instructions, then the outcome of the case will certainly be positive. The correctly executed filter will not be inferior to factory models that are sold in stores.

The device and purpose of the well filter

For the receipt of water from the well, a pump is required to be immersed in it. often it cannot regularly function in an environment in which large or small mechanical impurities are present. They negatively affect the device, reducing its resource, increasing the risk of breakdown. To avoid such consequences, the well is equipped with a filter.

All cleaning devices of this type have a similar design. They are installed in one- or multi-level systems. The main function of filters for a water well is to eliminate mechanical contaminants of different sizes. The main structural elements of the product are the following:

• the suprafilter part (to fix the device on the casing);
• cleansing component;
• sump (lower part of the equipment in which particles that fall into the casing) settled).

The main types of filters in the well for homemade manufacturing

The presented products increase the service life of the well. Since you need to choose it correctly, you should consider 2 main options:

• With additional cleaning. A gap between the well pipe and a layer of soil is provided, which is covered with selected gravel. For the same purpose, marble baby is used. This arrangement extends the service life of the filter.
• Without an additional cleansing layer. The walls of the device and liquid have direct contact.

Such a device for cleaning water in the country prevents the siltation of the well.

Types of nets

Galunnel weaving grids differ among themselves material manufacturing. Depending on the material of the grid, they are divided into two main groups:

Metal grids are produced according to GOST 3187-76 and there are various fractions. Such nets differ primarily by high strength, reliability, excellent filtering qualities and nomenclature variety.

Synthetic nets are produced according to technical conditions developed on the basis of GOST 3187-76. Modern polymeric materials are used for their manufacture. polyester and polyamide ra6. The properties characteristic of polymers prevent siltation and overgrowing of the grid with iron hydroxides and carbonates.

What are the nets in the well for?

Filters equip the water intake of wells, since uninterrupted work often depends on it, which increases well performance. The mesh filter for wells made of polyamide can last up to 50 years. However, when choosing a filter, they primarily pay attention to the territorial arrangement of wells, geological features of the area and the individual characteristics of a water intake. The minimum particle size that the filter captures depends on what size of the mesh cell. It is important to know that it is mesh filters that are less prone to various damage.

The filter consists of the following elements: firstly, an oenic base, secondly, a filtering layer with frames, thirdly, a sump for slag and fourth gravel sprinkling.

From all of the foregoing, we can conclude that the filter synthetic filter is necessary for the durability of wells, since various garbage and impurities can very much clog the well barrel so much that it will no longer function. The filter grid also helps to preserve hydraulic equipment. In a word, synthetic nets of galloon weaving are new generation grids.

The filter grid is realized a multiple of 1 m2.
