Description

The invention relates to power engineering, in particular to hydrodynamic neredacham. A hydrodynamic coupling is known, comprising pumping and turbine wheels forming a circle of circulation, an impeller filling chamber with impeller blades mounted on the pumping and turbine wheels, an input shaft connected with a motor driven H11m engine, and an output shaft associated with driven 1. A disadvantage of the known hydrodynamic clutch is that it does not have the technical means to allow it to be used as a means of protecting the drive engine and controlling the load on it MaiHHHbi alone. The purpose of the invention is to expand the functionality of the hydrodynamic coupling by using it as an equator,: 1Н1ОН1, for both the protection of the actuator and its motor, and the control of the load from the driven. This goal is achieved by the fact that in an idly dynamic coupling containing pumping and turbo wheels, forming a circle of circular, ai, impeller filling chamber with impeller blades mounted on the pump and turbine wheels, the input shaft. associated with the motor drive. The shaft connected to the driven machine, the pumping wheel is equipped with a doo-helical camera, which is hydraulically connected to the impeller's backup camera; 1pe P1, an additional tube is installed; 1a a scoop tube that connects hydraulically; 1polarly additional chamber with a circle of circulation and kinematically connected with a lever that is installed with the ability to interact with the controls of a drive motor or driven maple. On 4ig. Figure 1 shows the hydrodynamic coupling, scheme; on fi1. 2 is a section A-A in FIG. 1. The hydrodynamic coupling contains a pump 1 and a turbine 2 track, an impeller filling chamber 3 with impeller vanes 4, an inlet 5 and an output 6 shafts. A donor chamber 7, in which a black plumbing tube 8 is placed, hydraulically connects the additional chamber 7 to the circulation circuit of the working fluid in the pump 1 and turbo food 2 wheels. The ink tube 8 is kinematically connected to the lever 9, which is equipped with a spring 10 and is installed with the ability to interact with the medium 11 of a driving motor and driven by a machine, for example with a jack switch. The additional chamber 7 is hydraulically connected to the chamber 3 of the impeller filling by means of the aperture 12. The hydrodynamic coupling works as follows. When the drive-on device is switched on: 1I, the pumping section 1 accelerates to the rated speed. The working fluid located under the i5 mufflet, under the pressure of the 11th, forms in the cell, in the chamber 7, a liquid ring in which the tip of the scoop tube 8 is immersed. A chuck 8 li is injected into the working cavity of the coupling. In this case, the turbing wheel 2 is kept from rotation by the black (from the output shaft 6, and p1) by 1 step 9 under the action of: oment transferred from the cable) (the tubes 8 are pressed to the final switch. I. The impeller blades 4 lead to rotation of the working fluid, partially immobilized impeller filling chamber 3. As a result, these treads create: the resultant pressure, the effect of which causes the emptying of the working cavity of the coupling to begin. The emptying takes place until the nanor is developed by impeller; 4, mounted on the thrbnny Kcxiece 2, lower 1C, CISH data from pumps Ko; iecoM 1. 11ri slo.M at the output (the shaft 6 has a moment 1. corresponding to the residual effect of MOMtijTa acceleration is driven by the air and the angular velocity of the turbo | | | 1O1 () Ko.icca 2.

a liquid ring, which, acting on the blackened tube 8 ,. creates a moment on it, the node whose action is the lever 9, squeezing the spring 10, presses the limit switch. As a result, the regulator1 turns off (closing), its organ, for example, the gate valve, until the load, and, consequently, the slip, in the clutch reaches permissible flow. Controls 11, such as a limit switch, may be coupled to the drive motor. At the same time, with the load above the load on the input shaft 5, the drive motor is automatically shut off without overheating the clutch. Then the drive, which includes the coupling, can be switched on again without delay to recharge the coupling with a new working fluid.

Thus, the supply of the pump wheel hydrodynamic coupling containing

pumping and turbine wheels, forming a circular circulation circle, an impeller filling chamber with impeller blades mounted on the pump and turbine wheels, an input shaft connected to a drive motor, and an output shaft connected to a drive gear, an additional camera, hydraulically connected with an impeller-filled chamber, and installing a scoop tube in the additional chamber, which hydraulically connects the additional chamber with a circulation circle and is kinematically connected to the lever, installed Coupling with drive engine or driven machine controls allows you to spread fuktsion.: | Ipz1e coupling capabilities and the use of it, as a control, to protect the drive engine, and to regulate the load from the driven machine.
