Opis:
The article describes the results of experimental research concerning a prototypical hydrodynamic clutch controlled via changes in flow rates of the working fluid. The aim of the research was to collect experimental data to confirm the practical possibility of using such a control method of the hydrodynamic clutch and to compare this with other currently used methods. A change in flow rate of the working fluid was obtained by increasing the distance between rotors. The experimental research was conducted on a test rig built specifically for this purpose. On the basis of the research, the influence of the clutch filling level, the direction of rotation and the temperature of the working fluid on the clutch torque were determined. The experimental research shows that the transferred torque is significantly influenced by the width of the gap between rotors, the rotational speed of the input shaft, the clutch filling degree and the temperature of the working fluid. Thus, these values may be used to control the torque transferred by the hydrodynamic clutch. The temperature of the working fluid is not recommended as a control value due to the fact that it is dependent on the working conditions of the hydrodynamic clutch. On the basis of the test results, it was proven that hydrodynamic clutches controlled by increasing the distance between rotors can be successfully used, for example, in drive systems of wind farms.

Opis:
The article presents experimental and theoretical studies concerning the possibility of using a controlled hydrodynamic clutch in a wind power plant’s drive system. The hydrodynamic clutch is controlled by changing the distance between the hydrodynamic clutch rotors. The control system is supposed to maintain a constant angular velocity of the electric generator shaft. The considered method of control has not been used so far in power plant's drive systems. The advantages of using a controlled hydrodynamic clutch is simple structure, high durability and low weight of the entire drive system. The equations of the mathematical model for the drive system are formulated on the basis of: the balance of torques and the equations of the hydrodynamic clutch with retractable rotors. The equations are based on the one-dimensional flow of the working fluid along the mean line of the stream. The model calculations are conducted numerically. In order to be able to determine the coefficients of the mathematical model, experimental research is conducted on a test bench designed specifically for this purpose. The research determines how the rotation direction and size of the gap between rotors influences the torque transferred by the hydrodynamic clutch, for selected values of the clutch’s filling degree and the working fluid’s temperature. On the basis of the model calculations results it was determined that a hydrodynamic clutch controlled by increasing the distance between rotors may be successfully used in drive systems of wind power plants to maintain a constant angular velocity of the electric generator shaft.
