    M3o6peTeHkfe relates to pump compressor construction and concerns the improvement of the working bodies of the plates of rotary plate machines operating without lubrication of the working chamber with oil. A rotary plate machine is known, comprising a cylindrical body, end caps with inlet and outlet openings and an eccentric rotor in the body with radial grooves in which movable plates are placed, each of which has a coating in the area of contact with the inner surface of the housing, including polymer and solid lubricant l1. ; The disadvantages of this machine are the low durability and wear resistance of its plates due to intensive wear of the plate sections that come into contact with the body. Most rotary to the present invention is a rotary-plate car tire containing a cylindrical body, end caps with inlet and outlet openings and an rotor with radial grooves eccentrically located in the body, in which movable plates are placed, each of which has at least three layers , at least two of which are made of reinforced polymer, and at least one layer at least in the zone of contact with the inner surface of the housing contains inorganic solid lubricant C2l To the disadvantages The known machine refers to the low strength and wear resistance of its plates, which are subjected to intensive chipping during the operation, especially at high rotor speeds. The purpose of the invention is to increase proc. durability and wear resistance of the plates. This goal is achieved by the fact that in a rotary-lamellar machine containing a cylindrical body, end caps with inlet and outlet openings and a rotor with radial grooves eccentrically located in the housing, in which size 1: 1 there are flexible plates each of which has at least three layers, at least two of which are made of reinforced polymer, and at least one layer at least in the zone of contact with the inner surface of the housing contains inorganic solid lubricant, each reinforced layer is made of fluorocarbon polymer, a glass fiber reinforced or carbon fiber layer containing an inorganic solid lubricant placed mezhduarmir9vannymi layers, a solid lubricant is formed on the metal. Solid lubricant made of lead or its oxide. The layer containing the lubricant may be made of a film of a fluorocarbon ethylene propylene polymer or of a polyfluoroalkoxy polymer film. Figure 1 shows the proposed rotary plate machine; figure 2 - section aa in figure 1; Fig. 3 shows an embodiment of a plate having three layers, two of which are made of reinforced polymer, and the layer between them contains an inorganic solid lubricant; Fig. 4 is an embodiment of a plate in which the inorganic solid lubricant in the middle layer contains only in the contact zone with the inner surface of the housing; in fig. 5 - wah-
    a design of a plate having LAYERS; from reinforced polymer, between which layers are placed, containing in the contact zone with the inner surface of the housing inorganic solid lubricant; Fig. 6 is an embodiment of a plate having layers of reinforced polymer, containing an inorganic solid lubricant and bonded directly to one another; Fig. 7 shows an installation for the manufacture of reinforced layers; Fig. 8 shows an apparatus for producing laminated plates;
    The rotary plate machine contains a cylindrical case 1, end covers 2 with inlet and outlet openings 3 and 4, and a rotor 5 with radial grooves 6 located eccentrically in case 1, in which movable plates 7 are placed, each of which has at least three layers, at least two of which are made of reinforced polymer, and at least one layer at least in the zone of contact with the inner surface of the housing 1 contains an inorganic solid lubricant. In addition, each reinforced layer is made of a fluorocarbon polymer reinforced with glass or carbon fiber, a layer containing an inorganic solid lubricant is placed between the reinforced layers, and the solid lubricant is made on the basis of metal, and the solid lubricant is made of lead or its oxide.
    In addition, the layer containing the lubricant may be made of a film of fluorocarbon. Of ethylene-propylene polymer or of a film of polyfluoroalkoxy polymer.
     . Plate 7 (FIG. 3) contains reinforced layers 8-I 9 obtained, for example, by impregnating glass fiber mats 10 with polytetrafluoroethylene, and placed between reinforced layers 8 and 9, a layer 11 containing an inorganic solid lubricant made mainly of lead or its oxides. In addition, the layers 11 contain glass in the form of a powder or pieces of glass fiber for imparting resistance to the polytetrafluoroethylene material together with the solid lubricant. Layer 9, which is in contact with the rotor 5 and with corus 1 during the operation of the die, contains grit to reduce friction with the latter. Layers 9 and 11 are bonded to each other through films 12 of a fluorocarbon OR or a fluorocarbon or polyfluoroalkoxy polymer.
    In the embodiment of the plate (Fig.4) layer.
    11, containing inorganic solid lubricant, is made shorter than the others, and is located in the contact zone with the inner surface of the housing 1. In addition, such a plate 7 contains several reinforced layers 8 bonded to each other by means of films 12, and a reinforced layer 9 with graphite .
    The plate 7 shown in Fig. 5 contains several reinforced layers 8, bonded to each other by means of films 12, and the inorganic solid lubricant, mainly lead or its oxide, is in the form of a dispersion on these films
    12. For this, films 12 are coated with lead powder or its oxide, heated, after cooling, an excess amount of powder is removed. In this case, by changing the thickness of the film. ki 12 or lead size
    or its oxides can be. provide a different concentration of inorganic solid lubricant in the plate 7. In addition, lead powder or its oxide can be applied not to the entire surface of the films 12, but only to areas in the zone of contact with the inner surface of the housing 1,
    An embodiment of plate 7 (Fig. 6) provides for (the presence in it of several reinforced layers B bonded directly to one another. Layers 8 are made of a mixture of polytetrafluoroethylene and an inorganic solid lubricant, mainly lead or its oxide, reinforced with mats 10 of interlaced glass However, layers 8 can be made of a mixture of phenolic resin and organic solid lubricant, then the reinforcement mats 10 should contain the interwoven cotton.
    The plant for producing reinforced layers (Fig. 7) contains feed and take-up reels 13 and I, a tank 15 filled with an aqueous suspension of polytetrafluoroethylene and inorganic solid lubricant powder, a vulcanization chamber 1b, a mixing device 17 and guide rollers 18. An installation for producing laminated plates (Fig. 8) contains feeding and receiving reels 19 and 20, heater 21, rollers 22 and 23, press 2 and receiving hopper 25. The reinforced layer can be made as follows. A woven glass or carbon fiber cloth (or Kevlar fiber) from the feed reel 13 is guided by rollers 18 first to a tank 15 filled with water suspension of polytetrafluoroethylene and an powder of inorganic solid lubricant, mainly lead or its oxide. grease can be removed). In the tank 15, a mixing device 17, for example an impeller, ensures an even distribution of the particles in the suspension. The web impregnated with the slurry passes the drying and vulcanization chamber 16 and enters the receiving reel I of the Laminate Plate is made as follows. Several layers are placed on the feeding reels 19 in the required order, providing the necessary sequence of layers in the plate 7. The layers are heated to 300®C by the heater 21, are compressed by hot rollers 22 (with a temperature. Between the rollers 23 the tape thus obtained is cooled and fed to press 2. The finished plates are assembled in the bunker 25. These methods of making layers and plates of them do not exhaust all possible options and can be modified depending on the type of layers, the features of their arrangement in the plates Rotational-plate machine works as follows: When the rotor 5 rotates, the plates 7 placed in its grooves 6 and separating the sickle-shaped space between its outer surface and the inner surface of the housing 1 into variable volume chambers, provide sequential suction, compression and injection of the pumped working medium and moving it from the inlet 3 to the outlet (there may be several outlets). At the same time, the presence of a solid organic lubricant in the plate-organic grease made on the basis of a metal, mainly lead or its oxide, not only provides favorable friction conditions, but also (due to the additional mass) increases the contact pressure between the plate 7: and the housing 1, ensuring effective sealing of the working chamber . The effectiveness of the invention is to increase the strength and wear resistance of the plates.
