    4 WITH
    The invention relates to a compressor engineering, principally a high-pressure centrifugal blower.
    A high-pressure centrifugal blower is known, comprising a housing and an impeller located thereon on the shaft, on the drive disk of which radial vanes are fixed on its rear wall, and in the gap between the case and the drive disk there is a regulating element made in the form of a ring mounted to move along the axis of the impeller
    However, this blower has a complicated manufacturing technology.
    The aim of the invention is to simplify the manufacturing technology.
    This goal is achieved by the fact that in a high-pressure centrifugal blower, comprising a housing and an impeller located on the shaft, on a drive disk of which radial vanes are fixed on its back wall, and in the gap between the housing and the drive disk The shape of a ring mounted for movement along the axis of the impeller is mounted on the housing or on radial blades.
    The ring is fixed to the body with the help of adjustment screws and placed in an additionally installed guide ring fixed to the body.
    In addition, the diaphragm is made on the case with the formation of a cavity, is made of an elastic material, and the ring is installed in the cavity of the latter on the adjusting screws.
    Figure 1 shows a blower, a longitudinal section; 2 shows a variation of the blower when
    fixed on the roof; in FIG. 3 - the same, the ring is installed in the cavity of the diaphragm, in FIG. 4 - the same, the ring is fixed on the radial blades.
    The centrifugal blower includes a housing 1 and an impeller 3 located on the shaft 2, on a drive disk 4 of which radial vanes 5 are fixed on its rear wall, and an element made in the form of a ring is mounted in the gap between the case 1 and the drive disk 4 6 mounted with the possibility of movement along the axis of the impeller 3 and mounted on the housing 1 or on the radial blades 5, the ring 6 being fixed to the housing 1 by means of adjusting screws 7 and placed in an additional direction ring 8, fixed nnom also on the housing 1 (figure 2).
    In addition, on the housing 1 is fixed with the formation of the cavity 9, the diaphragm 10, made of elastic material, and the ring 6 is installed in the cavity 9 of the latter on the adjusting screws 7 (fig.Z). The shaft 2 of the impeller 3 is mounted in bearings 11.
    When the centrifugal blower operates at low revolutions of the impeller 3, the pressure in the gap between the casing 1 and the drive disk 4 is small and the axial force is sensed by the bearings 11.
    As the speed of the impeller 3 increases, the pressure in the gap between the housing I and the drive disk 4 increases, the axial force also increases, and the ring 6 compensates for the axial force by moving it along the axis of the impeller 3.
    The proposed blower allows one to simplify the technology of its manufacture by fixing the ring on the housing or on the radial blades.
