Description
Technical field
The utility model relates to field of thermal power, is specifically related to a kind of vapour, electric hybrid drives boiler feed pump.
Background technique
Feed water pump in station boiler subsidiary engine is very important equipment, is directly connected to normal start and stop and the operation of boiler.Feed water pump needs the driving arrangement of large air horsepower to drive, and generally adopts Steam Turbine Driven, but the deficiency that sometimes originates from; vapour source problem cannot be solved when starting and shut down; the feed water pump of Steam Turbine Driven cannot work, and needs the feed water pump separately establishing startup motoring, causes cost to increase.
Model utility content
The utility model object is to overcome the deficiencies in the prior art; providing a kind of vapour, electric hybrid drives boiler feed pump, not having enough vapour amounts or vapour source to cause the problem that cannot operate to solve thermal power plant for adopting when the startup of the feed water pump of Steam Turbine Driven, shutdown.
For achieving the above object, the utility model by the following technical solutions:
A kind of vapour, electric hybrid drive boiler feed pump, and comprise steam turbine, motor, clutch, gear-box and feed water pump, described steam turbine is connected with feed water pump respectively with motor, realize a feed water pump and adopt steam turbine and electric motor dual-power to drive.
Further, described steam turbine and motor are separately positioned on and feed water pump two ends, and steam turbine is connected by the input shaft of clutch with feed water pump one end, and motor is connected with the input shaft of clutch with the feed water pump the other end by gear-box.
Further, described steam turbine and motor are separately positioned on and feed water pump two ends, and steam turbine is connected by the input shaft of clutch with feed water pump one end, and motor is connected by the input shaft of fluid coupling with the feed water pump the other end.
Further, described steam turbine and motor are connected with same one end of feed water pump respectively, described gear-box adopts double input list to export multi-shaft gear box, the output shaft that double input list exports multi-shaft gear box is connected with the input shaft of feed water pump one end, and two input shafts that steam turbine exports multi-shaft gear box with motor respectively by clutch and double input list are connected.
Further, described steam turbine is condensing steam turbine or back pressure turbine.
The utility model has the following advantages compared with the prior art:
(1) at present boiler feed pump substantially all adopts steam turbine or motor single power to drive, and does not also have vapour at present, electricity pair drives configuration.
(2) adopt vapour, electricity is two drives feed water pump, solving feed water pump cannot the normal operation of feed water pump under steam supply or abnormal condition at steam turbine.
