Pipe 2 installed with the possibility of swinging in the receiving hopper (not shown) between the outlet openings of the working cylinders 1 and the inlet ot. There is a version of the injection pipeline (not shown) and has, at its end facing the working cylinder I, a portion of the cylindrical guide surface 4 and an annular projection 5 in the form of a flange. Switchgear also includes wear resistant
    . a ring 6 mounted with a gap on the guide of the cylindrical surface 4 of nozzle 2 (or removable part 3) and axially displaced relative to nozzle 2 and interacting with the support plate 7 fixed on the ends of the working cylinders 1 and having openings 8 aligned with the hole working cylinders 1, and installed between the ends of the wear-resistant ring 6 and the annular protrusion 5 of the nozzle 2 and cover the 1st cylindrical guide surface 4 of its elastic ring element 9 made of elastic rubber-like podzhiuprugogo material for the annular element 9 in its longitudinal direction of several successive concentric layers (1-5), each
    30 a layer of reinforcing wire 12 can be made in the form of a cylindrical helix or in the form of successively installed rings. At the ends of the elastic ring element 9
    25 protrusions 13 for sealing the mating in the contact zone of this element with a wear resistant ring 6 and an annular protrusion 5 of the nozzle 2, respectively (Fig. 4).
    The annular elastic element 9 can be sealed along the ends by elastic rings 14 of the 0-shaped cross section (FIG. 3), in this case the rings 14 are placed in the annular grooves 15 and 16, filled respectively in the wear-resistant ring 6 and the annular protrusion 3 of the nozzle 2, while Steel backing rings 17 and 18 are vulcanized to the annular elastic element 9 along the ends in the location area of the rings 14.
    The means for limiting the radial deformation of the elastic annular element 9 can be embodied in the form of a sleeve 19, completely covering the elastic annular element 9 and partially the outer surface of the wear-resistant ring 6, while the sleeve 19 can be installed with the possibility 45

    55
    wear-resistant ring 6 to the base plate 7.
    Wear-resistant ring 7 has an internal ring unchanged in height.
    matching diameter
    the diameter of the cylindrical guide surface 4 of the nozzle 2, and the elastic element 9 is mounted on the nozzle 2
    (or on its removable part 3) with the formation of a guaranteed gap 10 between its inner surface and the cylindrical guide surface 4 of the nozzle 2, communicated with
    the internal cavity of the pipe 2 with the aid of the gap 1I between the wear resistance of the CIM ring 6 and the pipe 2, and the switchgear is equipped with means for limiting radite 9.
    The means for limiting the radial deformation of the elastic element 9 can be made in the form of reinforcing
    wire 12 placed in the body
    elastic annular element 9 in its longitudinal direction in several successive concentric layers (figure 1-5), each
    a layer of reinforcing wire 12 may be made in the form of a cylindrical spiral or in the form of successively installed rings. At the ends of the elastic ring element 9
    protrusions 13 for sealing the interface in the contact zone of this element, respectively, with a wear-resistant ring 6 and an annular protrusion 5 of the nozzle 2 (Fig. 4).
    The annular elastic element 9 can be sealed along the ends by elastic rings 14 of the 0-shaped cross section (FIG. 3), in this case the rings 14 are placed in the annular grooves 15 and 16, filled respectively in the wear-resistant ring 6 and the annular protrusion 3 of the nozzle 2, while Steel backing rings 17 and 18 are vulcanized to the annular elastic element 9 along the ends in the location area of the rings 14.
    The means for limiting the radial deformation of the elastic annular element 9 can be embodied in the form of a sleeve 19, completely covering the elastic annular element 9 and partially the outer surface of the wear-resistant ring 6, while the sleeve 19 can be installed
    contact with the end of the annular protrusion. 5 nozzle 2 (Fig.7) or can be made in one piece with the annular extract 5 of nozzle 2, (Fig.6).
    When assembling the switchgear between the end of the wear-resistant ring 6 and the end of the nozzle 2 or its removable part 3, a guaranteed annular gap 20 is formed that extends into the internal cavity 21 of the nozzle 2.
    When the pump is operated, the wear-resistant ring 6 is pressed against the plane of the support plate 7 due to the elastic properties of the annular elastic element 9, while the reinforcing wire 12 or sleeve 19 (depending on the distribution node version) limits the radial deformation of the elastic element 9, ensuring its preferred axial deformation and thereby the tightness of the mating support plate 7 - wear-resistant ring 6 (the forces in the elastic element are schematically shown by arrows 22-24).
    The pressure of the pumped medium: from the cavity 21 of the nozzle 2 through the gaps 20 and 11 spreads to the zone of the guaranteed gap 10, where it acts on the elastic ring element 9. Due to the elastic properties of the material of the ring element 9, the hydrostatic force from the pressure in the guaranteed gap 10 decreases in the radial direction over the cross section of the annular element 9, as schematically shown by arrows 25 in FIG. 2, with the resulting forces providing additional preload of the wear-resistant ring 6 to the base plate 7, together with the efforts 22 and 23 from the pre-deformation of the elastic element g between the ends of the wear-resistant 9, are shown by arrows 26 and 27. At the same time, there is a decrease in the hydrostatic pressure in the annular gap 20, which is shown schematically by arrows 28, resulting in gustifying these killers in the radial gap. the direction of the forces is shown by arrow 29. FIG. 3 schematically shows a state in which, as the pump operates, the annular gap 20 at the inlet of gg cavity 21 of nozzle 2 is clogged with fine solid particles, which leads to a drop in pressure in this Ore virtually to zero. Since the roundabout
    ring and annular protrusion of the nozzle and an elastic annular element made of rubber-like material covering a cylindrical guide surface for pressing a wear-resistant ring to the base plate, characterized in that, in order to increase reliability and durability, the wear-resistant ring has a uniform fitting ring diameter of the cylindrical guide surface of the nozzle, and the elastic element is mounted on the nozzle with
    the gap I1 between the cylindrical guide surface 4 of the nozzle 2 and the wear-resistant ring 6 is open, the pressure in the gap 10 under the elastic annular element 9 drops and the wear-resistant ring 6 is pressed against the base plate 7 only by force 22 equal to, as indicated, the loading force from the preliminary deformation an elastic annular element 9, which, however, ensures the tightness of the mating wear-resistant ring 6 - support plate 7.
    Similarly, the tightness of the interface ensures wear-resistant ring 6 - base plate 7 in all versions of the pump distribution unit.
