The whole matter is in the vials of
At present hydromassage baths in the Russian market are offered by unlimited number of the companies. These are the Italian companies JACUZZI (that which has given the name to all commodity ruler!), ILMA, TEUCO, ALBATROS, French TES, NEOMEDIAM, Austrian PAMOS, German VILLEROY&BOCH, HOESCH, DUSCHOLUX, CALDEWEI, American RADOMIR, Finnish IDO, NOVITEC, SCANPOOL, Swedish CADAZZO and some other. The method of installation of a finished article on a place, in principle, everywhere is identical, but each producer can have nuances, which perfectly specify in advance.
The main difference of a hydromassage bath from the usual — existence of system of pumping. The centrifugal pump directs water on the pipeline, creating pressure of a stream. It settles down from the outer side of a bowl and submits water to each water jet (the special device for creation of streams in day of a bowl and its walls) or a nozzle. The capacity of the pump is defined by number of l., pumped over in a minute.
The centrifugal fan submitting air on the pipeline to each spray, forces there working pressure. From time to time instead of it establish the compressor. The volume of mixed air can be changed by means of a throttle and an entrance zaslonka. Situation of the last regulate or from a control panel, or manually. Thin streams of air which in water will be transformed to vials go to air jets under pressure (0,5–2 atm). Their nozzle often put on a cover with openings (jets with such covers are called as sprays), after all than more than vials and less their size, massage action is better than subjects. As air always подымается up, sprays have in day of a bath.
Nozzle call a jet which mixes water and air. It is capable to give out to 800 vials in a second. The volume of arriving gas can be reduced to zero, and then she will play a role of a water jet. Pressure of water does a stream in length to 6 m therefore nozzles establish only in walls.
Universal baths contain nozzles and sprays, their design foresees the pump, the fan. That they did not idle, from the outer side of a wall of a bowl the sensor of a water level which blocks these devices at its missing quantity is established.
The most part of producers when manufacturing similar adaptations for water supply and dispersion of air prefer strong plastic: the polymeric material is cheap, he does not carry out an electric current and is not subject to corrosion.
