FIELD: machine building.SUBSTANCE: in air-blast atomizer, comprising a housing with the supply of atomized fluid and gas, a jet guiding device and a sprayer, the housing is made in the form of an inverted bucket, the bottom of which is provided with a threaded hole to fasten the central cylindrical insert (axi-symmetric to the housing) with a central axial passage of the jet guiding device for the supply of atomized fluid, and perpendicularly to the housing axis the lateral surface of the housing is fitted by at least one hole for the supply of air (gas) under pressure, which is connected to an annular chamber formed by the external surface of the central cylindrical insert and the internal surface of the housing, and to the internal lateral surface of the housing, in its bottom part there attached is the cylindrical bush of the jet guiding device for the supply of gas under pressure to the sprayer via the annular gap formed by the external surface of the central cylindrical insert and the internal surface of the bush, the annular gap is connected to the annular chamber, a fluid flow swirling chamber and a diffuser are placed inside the central cylindrical insert on its internal surface coaxially and sequentially, the diffuser cut plane coincides with the annular gap plane at the output from the cylindrical bush of the jet guiding device for air supply.EFFECT: higher efficiency of liquid atomizing.1 dwg |
