Экспериментальные исследования крутящих моментов на лопатках направляющего аппарата обратимой гидромашины

Abstract

Reversible hydraulic reliability largely depends on the intensity of the hydrodynamic forces acting on the blades NA. Experimental determination of the torques on shoulder blades allows you to obtain reliable information for a wide range of operating modes of the hydraulic machine, including-pump, turbine, counter-braking mode and return pump, which is necessary for the development and design of the blades NA and the rotation mechanism, as well as to improve the theoretical methods of their determination. The results of studies of static and dynamic components of the torque on the blades NA reversible hydraulic machine in the universal characteristic for the conditions of the Dniester PSP conducted in GTL BAT "Turboatom". The analysis of the results obtained in order to identify the mode operating range of hydraulic machines in which there are high vibration blades NA defined limit line capacity based on the analysis of static and dynamic components of the hydraulic torque on the blades NA. The article provides an analysis of the frequency of the hydraulic torque.
