Hydraulic Externally very similar to the expansion tank flange heating systems. However, the appointment and service conditions have other, hence there are structural differences.
First, the mode of operation over the accumulator loaded. In normal operation, its frequency response ranging from 5 to 15 times per hour in a properly-chosen volume of the accumulator. If the volume is chosen correctly, this quantity can increase up to 20-30 times per hour. Of course such an operation requires a robust, resilient membrane that can withstand a large number of loads.

Secondly, hydraulic accumulators are used in household plumbing, so the material must be non-toxic and approved for use with clean drinking water.
Third, the water supply system in most cases comes from a well or wells. It is saturated with oxygen, which is released and accumulates in the membrane. Therefore, the large accumulator at the top of the diaphragm and the valve sleeve is to vent the air. The appearance of the accumulator presented earlier in Figure 5.
Fourth, the accumulators are usually placed on cold water line in the water system, so in terms of the temperature at which they are being more benign regime. Typically, the water temperature in the system can not exceed 30 ° C.
As Boilermate and indirect water heater systems, hydraulic accumulators are filled with water is not full. The volume of "issued" when using water accumulator is less than the useful volume of the expansion tank heating system.

Other features of the expansion tanks
Expansion tanks may be used to prevent damage to the system from water hammer. This phenomenon occurs in the pipeline at the sudden turn off or turn on the pump, quick opening or closing the valve. Loads can be many times greater than static and it can lead to the destruction of pipelines, threaded connections or plumbing devices. To avoid this, and given that the volumetric changes in the pressure variations are small, are encouraged to use expansion tanks of small capacity 0.2 liter

Also, tanks can be used as a tank with a fire liquid fire suppression systems, and as back-up tanks in those cases where the electricity is turned off. Hydraulic tanks are used not only in domestic but also in industrial and agricultural water supplies. At the same household series is designed for working pressures up to 6 bar and the Professional Series - up to 16 bar.

Before proceeding further to the detailed description and principles of selection of tanks, you need to say a few words about the main elements of these devices the membrane.

Choosing energy-efficient pumps for water wells and other needs
In the water supply borehole Circulating Taco 007 pumps play a major role in Tacoity consumption. Currently, their market is represented by numerous companies pumping near and far abroad. The bulk of the downhole Circulating Taco 007 should be allocated Grundfos, Taco, Espa, Little Giant, Pedrollo, Speroni, Dab et al.

Members of pumping equipment have a choice, and often, considering proposals analogues, preferred option with a lower initial price, paying no attention to the cost of subsequent maintenance. At the same time selecting the best option must be done from a position of minimizing the total amount of expenses for the period of the equipment. In this method of analysis will help the consumer life cycle cost of equipment, in which the main role belongs to the cost of the pump life. The amount of energy and materials used by the system depends on the type of pump, the type of installation and operation method of the system. These factors are interrelated.
Moreover, they must be carefully matched to each other, providing for its work, the lowest energy consumption, the lowest operating costs, other benefits. The initial purchase price is a small part of the cost of "life cycle" for commonly used pumps. Analysis of the life cycle cost is a management tool and can help companies minimize the amount of costs, maximize energy efficiency of pumping systems and determine the most effective solution. Components of the life cycle cost analysis typically include: initial cost, installation costs, fees, energy costs, maintenance costs, repair costs, downtime costs, environmental costs, the cost of recycling.

National and global markets become more competitive, organizations must continually look for ways to cut costs to improve profitability of their activities. Work equipment company deserves special attention as a source of cost reduction, especially as a source to minimize energy consumption and reduce the downtime of the enterprise. As an example, consider two alternative pumping equipment for installation in the borehole. The first option - the pump Little Giant 10-120-100, second option - the Grundfos pump 26-99.

Based on the high degree of reliability, due to reliable protection against surges and voltage fluctuations, overheating, overloading, "dry run", etc., the service life of Grundfos pumps more than two times higher than that of pumps Little Giant. To begin to compare the cost of the designed equipment: Little Giant 10-120-100 - 1493 Euro, and the SP 125-5-A - 7940 Euro.

PEX tubing pipe and household use
PEX polymer is a material obtained by cross linking the carbon atoms using three different methods. These methods result in PEX-a, PEX-b, PEX-c. Even though the same material is obtained by using these manufacturing processes, the difference is in PEX costs. It costs a lot less to fabricate PEX-a and PEX-b than it costs to make PEX-c.
Many times when using PEX tubing people can see that the resistance of this material is not quite as good as it should be. Used in bathrooms PEX has a major disadvantage.
When the cold pipe is placed next to the hot pipe, water will start forming on the cold pipe, and it will eventual fall on the floor. When living in a building, this means that the neighbors living downstairs will get a permanent wed wall from the pipes used above. The problem is usually solved with isolation on top of the polymer pipe. This means additional costs and additional work. If the bathroom has in wall pipes, the walls will have to be removed so that the plumber can reach the pipes.
Even so, PEX supply stores still have a lot of good things to say about the material they are selling. PEX supply companies have an increased demand for this product only because it is much cheaper than traditional metal pipes, and it is a lot easier to install and use, requiring far less fitting tools.
But costs can reach the same amount, when thinking of permanent replacements of the tubes. If the pipes work perfectly for the cold water installations, in hot water these pipes can cause a lot of problems.
What polymer pipes are really good for is electrical cabling. Some cables need to be placed on the exterior walls inside the hose, thus representing a danger to children or even to adults. Polymer tubes can hold the cables together in an isolating layer.
