Product Overview
YOTZH series variable-speed fluid couplings drive the conventional-island main feedwater pumps of 1,000 MW-class nuclear generating units. The series comprises YOTZH46/400, YOTZH51/450 and YOTZH46/450, combining a gear transmission with hydrodynamic speed control.
Design and Speed Control
The YOTZH series is an adaptation of the YOTZ design. It combines a gear transmission with hydrodynamic speed control, adjusting the output speed by varying the working chamber's fluid fill. The control cabinet, piping and housing form a complete hydrodynamic variable-speed drive assembly.
Selection and Ordering
Please provide the main feedwater pump model, drive motor power and speed, pump unit operating range, mounting interfaces and control requirements so that the model and configuration can be matched to the application.
