    The invention relates to compressor units with a screw compressor, which are connected to drive engines by means of a clutch with the possibility of transmitting drive force and adjusting the screw drive of the compressor (adjustment by intermittent operation).
    The purpose of the invention is to provide the ability to control the performance of a screw compressor by increasing the accuracy of the clutch.
    This regulation provides the ability to turn off and re-turn on the compressor units without the danger of thermal overload of the drive engine.
    Figure 1 shows a diagram of a compressor unit with a compressor unit connected with an. drive motor through a clutch; figure 2 - clutch, axial section; on fig.Z - node I on. figure 2.
    Compressor unit contains. a drive motor 1 connected to a drive compressor 2 by means of a centrifugal clutch 3, connected respectively to the driving and driven shafts 4 and 5. The screw compressor 2 is equipped with a suction pipe b, in which a check valve 7 designed as a damper and an air filter 8 are installed.
    From the screw compressor 2 to the pressure tank 9 leads pressure pipe 10, in which the oil trap I) is built. From the pressure tank 9 leaves the pipeline 12 consumption. Feed current to drive motor 1. through an electrical switch 13, which is activated through a pressure switch 14, which is connected to the pressure reservoir 9 via an adjusting pipe 15.
    The clutch contains the drive 16 and the half coupling that surrounds its driven 17 and the friction disks 18 and 19 mounted between them, alternately connected to each of the coupling halves with the possibility of movement in the axial direction, the pressure plate 20, the support ring 21 and placed between the latter centrifugal weights 22C Ma facing ends of the support ring 21 and the pressure plate 20, the guide surfaces for centrifugal weights 22 are made. The pressure disk 20 is mounted With the possibility of movement in the axial direction. In the coupling parallel to the axis of the installed return spring 23, one end of each of which is connected to the clamping disk 20, the other with the support ring 24.
    The coupling has at least one ring spring 24 with one additional support ring.
    the electrical switch 13 is again in the open position (Fig.). The drive motor 1 loses its torque ц at first for a - a short period of time rotates more slowly with the screw compressor 2. In the event that a certain frequency is not reached, turn the centrifugal loads 22 by the action of the reversed-stroke | Q req 23, they are reversed (Fig. 2), with the presser disc 20 simultaneously moving away from the friction discs 18 and 19. The connection between the drive motor, | 5 I and the screw compressor 2 are quickly disconnected, the screw compressor 2 stops quickly, the check valve 7 is closed and the drive engine 1 is turned off. As 20, only the pressure in the pressure tank 9 drops below a certain arbitrarily chosen level, the electronic switch 13 again closes - | s, and another 25 cycle runs.
    A centrifugal clutch 3 located between the drive motor I and the screw compressor 2 provides the ability to start the compressor unit at a full supply pressure in the tank 9. In this case, it is not necessary to remove air from it before starting the screw compressor 2. Neither the screw compressor 2 nor the centrifugal clutch 3 requires any other control operations, and the clutch is automatically closed and opened at the right time. Since the drive motor 1 will drive up the drive force only to the screw compressor 2, as soon as the compressor is driven, it has a rather large torque, as a result of which the thermal overload of the drive motor 1 is prevented by means of a centrifugal clutch 3 the unit can be re-enabled and disconnected with short breaks of the CQ vamp in time without damaging the drive motor 1.
    Since switching on and off due to the special design of the proposed centrifugal clutch occurs quickly, the friction discs 18 and 19 are under load only for a short time, as a result of which the centrifugal clutch 3

    subjected to slight nchposu. Such a short turn-up time of the coupling and a relatively large acceleration pressure mixture is provided, j) in particular, by the presence of ring springs 24, which press the driving disk 18 through the friction lining 32 against the pressing-gnome disk 20 so that the support ring 21 when the driving hole starts 1 is quickly turned into rotation. The recoil springs 23 also contribute to this. The constant circulation of air contributes to the cooling of the drive discs 18 provided. Under the action of centrifugal force, the air from the vent holes 29 in the drive discs 18 flows radially outward, and is sucked through the axial grooves 28 and vent ducts 30 from the open channels 31. , high thermal load on the 2B heavy coupling is prevented
