The turbine-driven feed pump coupling is a key transmission component connecting the steam turbine and boiler feed pump in power-plant turbine systems. It not only transmits power between the turbine and feed pump, but also effectively compensates shaft misalignment, absorbs shocks and dampens vibration during operation to ensure stable system performance.
Its performance directly determines efficiency, reliability and safety of the turbine unit, making it an indispensable part of power-plant equipment.
Product Features
High-precision Power Transmission
Adopting advanced manufacturing procedures and high-precision machine tools, the coupling meets stringent transmission-accuracy standards
Transfers turbine power to the feed pump efficiently and precisely, minimizing energy loss and improving overall system efficiency
Precision-fit connecting components guarantee stable and reliable power transmission over long-term service, preventing equipment failure or abnormal operation
Excellent Misalignment Compensation Capacity
Compensates radial, axial and angular misalignment between turbine and feed pump shafts
Accommodates various misalignment conditions arising from installation and thermal operation in power plants
Reduces vibration and abrasive wear to extend equipment service life
Flexible compensation elements permit controlled elastic deformation for automatic misalignment adjustment
Eliminates need for frequent re-alignment of equipment, simplifying installation and maintenance
