Accumulator with own hands: device, principle of operation, connection

Living in your own home or at the dacha should be as comfortable as possible. Therefore, the construction of all life support systems is paid special attention during the construction phase. Some owners, wishing to save money, do it on their own. When all water lines and pumping equipment are installed, it is necessary to think over the installation of the storage tank.

This device will save considerable energy. The pump will turn on much less often. It is quite possible to mount a hydraulic accumulator in the water supply line. It can also be made independently from various improvised means. If there is enough free time and minimal skills in working with the tool, it will be possible even for a beginner master.

The structure of the tank

The device of the accumulator is quite simple. It consists of a container. It has a certain volume. Inside this tank there is a membrane or a rubber pear. As a supplement to the capacitance, measuring devices are connected, but they are not necessary.

The main functions are assigned to the membrane. It prevents mixing of air and liquid, which allows creating the necessary pressure in the system. The rubber partition divides the tank into two compartments. In the first one there is air, in the second - water.

If the amount of water increases, the air is compressed. When the tap is opened, it will push the liquid out of the container. This forms the pressure when running a water pipe in a private house.

In addition, the described principle of operation of the accumulator allows maintaining a uniform pressure, and also eliminates water hammering while the pump is running. This significantly increases the duration of equipment operation, reducing the number of failures of the component parts of the system. Therefore, installing a storage tank will be the right solution.

General recommendations of experts

Many owners of suburban real estate have the desire and the opportunity to make a hydroaccumulator for water supply systems with their own hands. To do this, you need to understand the issue of the water supply system. Thus, in the city, the pressure in the system is maintained at a level of about 1.5 atm. But for the private sector it will be sufficient to maintain this figure in the region of 1 atm. This will help pick up the right equipment in the store or create it yourself.

Experts say that it will be quite easy to make a storage tank independently. In its functions, it will not yield to its purchased varieties in anything.

Hydroaccumulators for water supply, the price of which starts today from 700 rubles, will cost much less. The more components there are in the household of a home master, the less you will have to pay for capacity. It is necessary to follow all the recommendations of experts so that the result is good.

Necessary materials

Hydroaccumulators for water supply, the price of which does not hit the family budget, is quite simple. For this, it is necessary to prepare several components of this equipment. First of all, you need a capacity. It can be plastic or aluminum. Its internal walls should be smooth and smooth. If this condition is not met, the pear or membrane will tear when stretched.

The volume of the tank should be at least 30 liters. But it is better to choose a capacity even more. Everything depends on the consumption of water in a particular house.

Further, a pressure switch, as well as any manometer, is required. From the fittings you need to buy a quarter and a tee, as well as a stopcock. Usually, a ¾-inch armature is used for this purpose. Also need a half-inch and a ball valve.

A normal bicycle chamber (nipple) will serve as a membrane or pear. For the manufacture of all necessary gaskets you will need a sheet of rubber, as well as a sealant. Fasteners are nuts and washers.

How to choose the tank volume

Knowing the device of the accumulator, you can create this equipment yourself. But before you start, you need to correctly choose the volume of the tank. On this depends the correct functioning of the water supply of a dacha or a country house. Typically, for these purposes, a capacity of 30 to 50 liters is suitable.

But this amount must be coordinated with the capacity of pumping equipment. If the power supply is often turned off (this happens in holiday villages), a larger amount of accumulator is required. Water will fill about 1/3 of the tank.

Also, remember that if a powerful hydraulic pump is installed in the system, a larger tank will be required. This will reduce the number of short-term inclusions of equipment.

However, too much capacity will not be a good solution. Water inside will stagnate, and its quality will decrease. Therefore, to give a tank of 50 liters is almost the maximum permissible option.

Work instruction

The principle of operation of the accumulator is quite simple. It is easy to recreate in self-made equipment. To do this, it is necessary to drill holes in the selected tank at the bottom, on the side and on the lid. At the top, a 1/2 "tap is installed. It is fixed with washers, installing gaskets and blowing with foam. This will avoid leakage.

When this part of the work is finished and the sealant dries, a quarter must be attached to the tap. A nipple, a pressure switch and a pressure gauge are attached to this part. At the bottom of the tank, a ¾-inch tap is installed. To it the tee is fastened.

The side opening is retracted for the ball valve. The nipple is fixed with a plug. It must have an internal thread. Also all connections must be sealed. It's a tank without a membrane.

First start

After the operation, it is necessary to start the pump with accumulator. For this, several important principles must be observed. First the pump starts. Then a ball valve opens on the side surface. Water must flow from it.

If this condition is met, the valve is closed. By means of a conventional bicycle pump, air is pumped through the previously installed nipple into the tank. The vessel must be provided with the necessary pressure. It is checked using a barometer and is from 1 to 1.5 atm.

If the pressure does not meet the requirements, with the help of the relay, regulate its value. This trial first run is necessary. When the system is tested, it can be fully exploited.

Tank type

There are two basic types of fixing the tank. On this depends and its adjustment. There are vertical and horizontal accumulators. The fact is that in the part of the container in which the liquid is located, a small amount of air will accumulate over time. It must be removed from time to time. This will save the system from unfavorable air congestion.

If the container has a vertical arrangement, it requires a special nipple. Air in a tank of this type accumulates at the top. It will be easier to remove it.

The horizontal type of tank differs in this from its vertical counterpart. Not only the nipple is required here. To bleed out excess air, a ball valve is required. Also, the system provides for draining into the sewage system.

How to bleed air

When creating a hydraulic accumulator with your own hands, you must also know the rules of its operation. For small tanks, there is a certain system that allows you to simply remove excess air from the tank.

Some systems assume to bring water from above. This happens quite rarely. It is better not to build such a system on your own. For her, as experts say, you do not need to bleed air from the tank. But such a system is complicated by the presence of special filters.

For a homemade small tank there is a simple procedure for eliminating air. In this case, the power supply is cut off. The mixer tap opens, the tank is emptied. Then the valve is closed and the pump is turned on again. The container is filled with water. Excess air exits with the liquid. This must be done at least once a month.

A new tank from the old

You can create a new tank from old non-working equipment. Most often in them out of order is the membrane. A new punch for a hydro accumulator will solve the problem of creating a new tank.

In tanks for cold water supply special food rubber is used. It is safe to operate, it does not harm human health. Also the operating pressure threshold for such products is quite large and can reach 8 bar. Therefore, before creating a new tank, you need to buy a pear or a membrane with the same characteristics as the previous tank element.

You can use the same technology that was presented above, but provide the tank with this part. But in this case, the calculations will have to be given more time. Therefore, it is more suitable for repairing an old, failed tank.

Pear changing

By creating a hydraulic accumulator with your own hands, you can repair the old tank. This is a fairly simple process. After buying a new pear, you can start working. The tank must be untwisted. For this, the bolts of the connections are unscrewed. After that, the old membrane can be easily removed.

The new pear is installed in place of the old part. The accumulator is collected in reverse order. Bolts must be tightened evenly. If the action is not accurate enough, the membrane can slip and fall inside the bulb. In this case, you will have to repeat the procedure again. To prevent this from happening, the bolts are tightened first easily, and then evenly tighten the fasteners in all places.

Having considered the technique how to make a hydro accumulator by one's own hands, each owner of a dacha or a country house will be able to create this element of the water supply system. It will allow to extend the work of all equipment. Enjoy the water will be comfortable.
