At the same time, in order to protect the solder from oxidation, the device can be equipped with a protective casing mounted on the nozzle in the form of a cylindrical element surrounding the nozzle, partially immersed in the solder, with a lid in which a central hole is made, while the gas distributor is installed in the form of a ring-shaped tubes with openings connected to inert gas sources.
    The drawing shows the proposed ycTpoifcTBOo.
    In the device under the bath 1 with liquid solder 2 and electric heaters (not shown) there is a single-phase magnetohydrodynamic pump for liquid metals with winding 3, core 4 and supercharger. A device is inserted into the bottom of the bath, into which a paddled rotor 5 is inserted, a connecting nozzle 6, which is a hollow cylinder, has a lower end
    Rennei the surface of which is beveled relative to its axis at an angle of less than 90, the sleeve 7 and the sleeve 8, rigidly connected between each other. The sleeve 7 is a hollow cylinder, the upper end of the inner surface of which is joined at an angle of less than 90 relative to the axis of the nozzle 6. The sleeve 8 0 is a hollow cylinder with a conical bottom, the upper end of the outer surface of which is beveled and parallel to the canted upper end of the inner surface bushings 5 7. The heartbeat 4 is covered at one end by a winding 3, and at the other end by a supercharger. Above the beveled part of the nozzle 6 are evenly spaced at the same height of the orifice 9. Lower end 0 6 The sleeves 7 are sloping and parallel to the lower conical part of the inner surface of the nozzle 6. The sleeve 7 and the nozzle 6 are connected by means of a movable tip. He contains
    tube 10 and a cylindrical vessel. The cylindrical vessel consists of the upper П and the lower 12 disks and the lateral surface 13. The upper 11 and lower 0 12 disks are located close to each other and have central holes that are connected respectively to the core 4 and to one end of the tube 10. The other end of the tube 0 is connected to the lower end of the nozzle 6. The bottom of the bath 1 is connected to the upper disk 11 by means of one or more metal pipes 14. The tube 10 and the upper disk 11 are made of ferromagnetic material. Concentric to the winding 3 and the side surface 13 there are two or more external magnetic leads 15, connected at one end to the core 4, and at the other to the top 5 disk 1. The IO tube concentrically covers the core 4. To the top of the nozzle 6 a protective cover is fixed, made up of a cylindrical part 16 and a cover 17, tightly attached to it. The cover 17 has a central opening 18. The cylindrical part 16 is partially immersed in the solder 2, covers the nozzle 6 and is rigidly fixed to it by means of supporting devices 19. Under the cover 17, the gas distribution is located around the central opening 18. a hinge 20, which is an annular tube with holes,
    connected by means of a valve-reducer with an inert gas source. Between the nozzle 6 and the use of 8 is confuser 21. The upper bevelled ends of the sleeve 7 and the sleeve 8 form an annular channel 22.
    The device works as follows.
    The initial melting of the solder in the bath 1 is carried out by electric heaters and induction by a single-phase magnetohydrodynamic pump. After melting, the solder nozzle rises to the upper position (in accordance with Archimedes law), and the sleeve 7 rests on the cover 17. Thus, a closed space defined by the nozzle 6, the surface of the liquid solder 2, the protective casing and the sleeve 7 is formed. By means of the gas distributor 20 This space is filled with a protective gas (for example, nitrogen) with a low pressure. Liquid metal 2, sucked from the bottom of the bath 1, passes through the metal pipes 14, the blower, the holes 9 and returns back to the bath 1, DST:, T1 of the atmospheric air to the solder is interrupted. When the rotor 5 is inserted into the socket of the sleeve 8 of the FSC, the pump is loaded under the influence of its weight and closes the openings J, Solder 2 flows out of the annular channel 22, at the same time pours all the collector's feathers and back, returns to the bath 1. When the nozzle doubles down, the sleeve 7 is separated from the cover 17 and the protective gas begins to pass between the flow ;; gnzky pr.gncho 2 and the cover 17, forming the tach of the safety cushion G23ovuk. After the completion of the process, the rotor 5 is taken out of the heel 8, with which the working cycle is carried out, and the installation causes its resting position.
    In the case of when it is necessary to retract rotors with different collector diameters, 5 of the sleeve 8 is replaced with a new diameter of the socket with a diameter of 1 cm. Then the described duty cycle is repeated.
