In the private sector, most owners prefer to take care of the water supply of their homes and not to overpay for the centralized supply of this resource. Moreover, the cost of such a service clearly does not match the quality of what follows from the cranes. One of the main elements of the scheme is a hydraulic accumulator.
By the way, it is often confused with an expansion tank, although there are some differences between these products.
To understand how to properly and according to what scheme to connect the accumulator, you should remember why it is needed. Already from the name of this device it is clear that it is intended for accumulation of liquid. If you do not mount it, the pump will turn on every time the tap is opened at the point of water extraction, and taking into account the non-absolute tightness of the circuit, it also works for a while in idling mode( until the pressure rises to the nominal value).
Regardless of the design of the housing( vertical or horizontal installation), there are certain rules for connecting accumulators, which are shown in the diagrams:
But if you look closely, you see that the principle of connection, the scheme is the same. Consider this for an example of a simplified scheme:
Pump( H) is designated pos.1 , after which the dry-running relay( 2) and always return the valve( 3) . Pressure switch( 4) "controls" the on / off "H", that is, together with the accumulator( 6) provides the most favorable operating mode for it. For the visual inspection of the status of the water supply circuit, manometer( 5) is installed.
Whatever configuration the route has, from whatever manufacturers all the components of the water supply system are purchased, the scheme for including the GA in it remains unchanged.
What to take into account
-
For sealing( sealing) threaded joints, it is better to use a FSM tape. Secondary use of the old material( of any type - tow, the same tape, thread) is not allowed. This will entail not only water leaks, but also cause a malfunction in the operation of the automation, and as a consequence, a violation of the operating mode of the pump. - It is necessary to correctly select the optimum volume of the tank GA - it must correspond to a specific contour, the intensity of water flow and a number of other conditions. Acquire the device on the principle of "the neighbors are the same" is not only wrong, but also unacceptable. Here we need a preliminary calculation of the parameters of the circuit.
- The location of the accumulator must be selected in such a way that it can be easily serviced, and the temperature in the room must never fall below +5 ° C under any circumstances.
- The nuances of the connection depend on the GA model. In some products( usually small volumes) there is no bleeding valve.
- A hydraulic accumulator for cold water is placed in the water supply system. This should be paid attention at the point of sale.
