<p>An invention pertains to the heat engineering, in particular it is related to the heat and water supply systems. The superimposed electromagnet offered is predicted for peeling off the salts scale from the interior walls of water supply tubes. An apparatus consists of coil (2), predicted for switching into the industrial or urban electricity supply network, and magnetic core (4) that is not completed on itself as construction but is being completed in actuation time. Besides, the completing part of magnetic core (4) is span of water main (3) under the electromagnet (2, 4). An apparatus is provided with stepwise control device being formed into shape of removable ferric gaskets (5) of different thickness that are installed between a core (4) and a tube (3). In order to form the gaskets (5), the ferric plates are used number thereof being equal to the number of branches of magnetic core (4) stem. Fig. 3 shows one implementation alternative of an invention for descaling the water supply tubes.</p> |
