Abstract
The utility model relates to a steam extraction back pressure type water feeding pump small turbine system with a high-efficiency hydraulic speed regulating device, which comprises a steam extraction back pressure type water feeding pump small turbine, a high-efficiency hydraulic speed regulating device, a water feeding pump, a small power balance generator and a main turbine; an output shaft at one end of the small steam turbine is connected with the high-efficiency hydraulic speed regulating device, and an output shaft at the other end of the small steam turbine is connected with an input shaft of the small power balance generator; the high-efficiency hydraulic speed regulating device is connected with a water feeding pump, and the main steam turbine is connected with a steam inlet pipe of the small steam turbine through a middle steam extraction pipeline. The utility model discloses can guarantee that little steam turbine admission governing valve keeps full open operation in order to reduce the throttle loss, can improve the design efficiency 4-5% of little steam turbine. In addition, as the hydraulic speed regulation device adopts the internal structures of the hydraulic coupler, the hydraulic torque converter and the planetary gear, compared with the traditional pure hydraulic coupler for transmission speed regulation, the efficiency of the speed regulation device can be greatly improved by 4 percent, the speed regulation range can reach 10 to 100 percent, and meanwhile, the reliability of the whole transmission speed regulation is higher.
