opening the valve in a country house, which is rarely the owner thinks about where it takes water.Of course, everyone knows that the source of life-giving water supply system - borehole and that of her water enters the house with the help of a hydraulic pump.But one of the main elements of the system says not everyone.Meanwhile, for the uninterrupted supply of water and extend the life of the system are essential for water supply accumulators.
function accumulators in the water system ↑
storage for water supply systems, orpressure vessel for water storage and maintenance required for the proper functioning of the system pressure and acts water hammer absorber, resulting starting the pump or opening of valves.It is this structure is responsible for creating the necessary pressure for correct operation of the water system.
Interestingly hammering terrible not only "spitting" from the tap.They can seriously damage not only the elements of the water supply system, and plumbing.
Of course, the use of accumulators is not a prerequisite.In an open system, which serves as the basis for a large water capacity, located on an elevated, this device is generally unnecessary.
But for a country house usually used closed circuit water with accumulator.This avoids a large number of problems.
Important: the device significantly increases the service life of the pump by reducing the number of short-term inclusion of the system.Besides installing the accumulator compensates for expansion of water in the pipes, avoiding excessive pressure.
Design and Function accumulators ↑
Pressure tank consists of a sealed enclosure, made of metal and rubber membrane, like a balloon, but it is highly durable.All space between the flexible membrane and the housing is filled safe for living organisms inert gas.Accumulators are installed on the pipe and attach it to the flange connection.
How valid pressure vessel?First, the water enters inside the elastic membrane and stretches it, whereby the gas, located between the housing and the membrane is compressed, increasing the pressure on the membrane.It is due to the elasticity of the elastic membrane and the gas pressure in the supply line is supported by the right level of pressure.Upon reaching the required value of the pressure inside the rubber tank pump shut off by a special relay.When the valve opens, the pressure decreases and the pump is actuated again.
permanent supply of water in the accumulator to avoid short-term pump starts, leading to its rapid wear.Typically, the amount of the headbox adjusted so that it contains not less than the fourth part of the maximum minute water consumption in the building.Of course, much of this time do not have time, but rinse your hands or dial a cup of water for fifteen seconds is quite possible.Moreover, the situation is when the house is a maximum withdrawal of water, is extremely rare, so the supply of water in the accumulator can be enough even for washing dishes.
types of accumulators: how to make the right choice ↑
accumulators are divided into two types:
type name of the device is fully consistent with the method of installation.The choice is easier if the room allows you to use only one type, but if the size of the room make it possible to use both vertical and horizontal pressure vessel, it is very difficult to stay on any one.
In this case, you should pay attention to the way vented from a rubber membrane.Probably everyone knows that water always contains dissolved air, which eventually released and forms air pockets in different parts of the water system.
cavity membrane - is no exception.So, to vent this air for each accumulator for water instruction provides for an additional pin.
Vertical accumulators accumulate air in its upper part and it can be easily derived using such a simple device, but in the pressure tanks horizontal type requires installation of an additional section of the aqueduct, including a ball valve, airnipple and discharge into the sewer.
Tip: bleed the air from the hydraulic accumulator should be at least once a month.
Bleeding true only for tanks with a capacity of more than 100 liters, the choice of a smaller volume of the accumulator is limited to easy installation model.Trapped air pressure in the tanks of small capacity removed periodic full discharge.
Tip: bleed the air from the hydraulic accumulators small volume can be through the faucet washbasin or any other point of the draw, but you first need to disconnect all electrical installation.For best results, this procedure should be repeated several times.
roller introduces the opinions of experts about the functionality and benefits of equipping the water supply system accumulator:
Unfortunately, the majority of pressure tanks imported into practice are totally adapted to the peculiarities of our water systems.Therefore, this equipment is very quickly fails.Accumulators JEELEX for water supply made by a Russian company that developed the excellent equipment, ideal for domestic conditions.In addition, these devices have a lower rate in comparison with foreign analogs.
