Abstract

The invention relates to a novel feed water pump system and an operation method thereof. The novel feed water pump system comprises a feed water pump turbine, a high-speed clutch, a steam-driven feedwater pump, a hydraulic coupler and a motor; one end of the high-speed clutch is connected with the feed water pump turbine; the steam-driven feed water pump is connected with the other end of the high-speed clutch, when the high-speed clutch is engaged, the feed water pump turbine is connected with the steam-driven feed water pump through the high-speed clutch and drives the steam-driven feed water pump to rotate, and when the high-speed clutch is disengaged, the feed water pump turbine is separated from the steam-driven feed water pump, and the feed water pump turbine stops driving the steam-driven feed water pump to rotate; one end of the hydraulic coupler is connected with the steam-driven feed water pump; and the motor is connected with the other end of the hydraulic coupler, and whenthe hydraulic coupler is engaged, the motor is connected with the steam-driven feed water pump through the hydraulic coupler and drives the steam-driven feed water pump to rotate. According to the novel feed water pump system, water feed pipelines and valves of a water feed system are reduced, the system configuration is simplified, and the safety of the water feed system is improved.

Description

technical field [0001] The invention relates to a shaft coupling device, in particular to a novel feedwater pump system and its operating method. Background technique [0002] The basic configuration of the new feedwater pump system is as follows: the feedwater pump steam turbine is connected to the steam-driven feedwater pump through a high-speed clutch, and the motor is connected to the steam-driven feedwater pump through a hydraulic coupling. All devices are on one axis. [0003] It involves the settings of the feedwater pump steam turbine and the electric motor as the driving equipment, switching between normal working conditions and fault working conditions, and adjusting the speed of the feedwater pump. This patent integrates the advantages and disadvantages of the conventional feed water pump system operation mode, and sets the operation mode of the new feed water pump system to ensure the normal operation of the system. [0004] In the process of realizing the pres...
