Abstract
The utility model relates to a kind of transverse core Structure of RCP, and this core Structure of RCP is made up of stator, end socket, drainage tube, damage in impeller ring, nut, key, impeller, rotating shaft, stator wear ring, a harness fastener, kingbolt, mother nut, taperliner, motor, pressure vessel wall etc.This transverse core main pump can realize reactor coolant is circulated with the flow of regulation under the driving of motor, and the heat that reactor core produces is passed to secondary circuit by steam generator.This pump is the constituent element of reactor coolant loop pressure boundary, can ensure the structural integrity of reactor coolant pressure boundary, can simplify the structure of whole nuclear power plant system simultaneously.
Description
Technical field: the utility model relates to a kind of transverse core Structure of RCP.
Background technique: the small-sized heap of modular type being satisfied different demand, safe, reliable, the viable economically and anti-nuclear proliferation of the positive encourage growth of International Atomic Energy Agency.The Nuclear Power developed country is while development large nuclear-power unit, and also all actively researching and developing multipurpose modular type Small reactor, these small-sized heaps comprise light water reactor, high temperature gas cooled reactor, liquid metal cooled fast neutron pile, MSR etc.
In recent years, external a lot of nuclear power technology developed country comprises the states such as the U.S., Russia, Argentina, Korea S, Japan, South Africa and is all being devoted to research and develop the middle-size and small-size multipurpose reactor that Security is good, have again economic competitiveness, be mainly used in generating, also can take into account thermoelectricity, water power alliance and other specific use etc., a part of middle-size and small-size reactor has entered the engineering research stage.External such pump in recent years drives to maturity stage soon.A lot of nuclear power technology developed country is being devoted to research and develop the middle-size and small-size multipurpose reactor that Security is good, have again economic competitiveness.
At present, single development coastal large nuclear-power unit can not adapt to the requirement of the wide model application of nuclear energy completely.From the nuclear power market demand, the power supply of developed country and medium-developed country has been tending towards saturated.Following nuclear power demand will transfer to the developing countries gradually and energy starved is national and hinterland, these countries and regions, by the restriction of geographical position, geology, meteorology, water source, economic capability and net capacity, are not suitable for building large nuclear-power unit.And the design object of small-sized heap also focuses on the generation from the former upper elimination accident of root, eliminate primary Ioops main pipeline, thus eliminative reaction heap cooling system loss of-coolant accident (LOCA), and can effectively at minimizing off site emergency measure and human intervention when running into emergency episode.At present, because this small-sized used by nuclear reactor core main pump technology still belongs to blank at home, therefore the core main pump technology be directly positioned on pressure vessel wall of Small nuclear power plant transverse lacks especially.
Summary of the invention: the purpose of this utility model is to provide that a kind of structure is simple, stable performance, reliable, safe a kind of applicable Small nuclear power plant designing requirement transverse core Structure of RCP.The technical solution of the utility model is: a kind of transverse core Structure of RCP: the ingress of pump is provided with a drainage tube (3), and drainage tube is fixed on stator (1); Damage in impeller ring (4) is fixed on drainage tube (3), and stator wear ring (9) is fixed on stator (1); Impeller (7) is arranged in rotating shaft (8) by key (6), and is fixed on axle (8) by nut (5) by impeller (7); Together with stator (1) puts together on the support of motor (14), stator near waterexit end bottom adopt end socket (2) seal; Motor (14) is fixed on pressure vessel wall (15) by kingbolt (13), mother nut (11), taperliner (12).
Working procedure of the present utility model is: motor (14) impeller (7) rotates, impeller (7) by intrasystem medium through pump drainage tube (3) import after, after impeller (7) rotational energy increases, medium is after stator (1) water conservancy diversion, then the exhaust port on stator (1) is discharged in the pipe-line system outside pump.
Technological merit of the present utility model is:
1, core main pump of the present utility model does not have special pump case, and stator plays the effect taking into account pump case simultaneously.Because this small cores reactor eliminates the main pipeline of primary Ioops, save the space of modular small nuclear reactor pressure container, for core main pump, also save material simultaneously.
2, core main pump of the present utility model is the constituent element of reactor coolant loop pressure boundary, can ensure the integrity of reactor coolant pressure boundary system architecture.
3, core main pump of the present utility model pumping section to be divided and after the independent installation of drive unit, more overall be inserted in pressurized container, and install and keep in repair convenient, the withdrawal space is little.
4, core Structure of RCP feature of the present utility model is that delivery side of pump is opened on the barrel of stator cylindrical shell side.
Accompanying drawing illustrates:
Fig. 1 is a kind of core Structure of RCP of the utility model schematic diagram
Embodiment:
As shown in Figure 1: a kind of transverse core Structure of RCP, puts together on the insulator of motor 14 by stator 1, be fixed on stator 1 by stator wear ring 9 simultaneously; Impeller 7 is positioned in the rotating shaft 8 of motor by key 6, by nut 5, impeller 7 is fixed in the rotating shaft 8 of motor; Damage in impeller ring 4 is first fixed on drainage tube 3, then is fixed on by drainage tube on stator 1; Stator 1 near waterexit end bottom adopt end socket 2 seal; Motor 14 is fixed on pressure vessel wall 15 by kingbolt 13, mother nut 11, taperliner 12.Drainage tube 3, as the entrance of pump, can require to make corresponding amendment in ingress according to the difference in power station.Motor 14 rotates impeller 7 and rotates, and by intrasystem medium after the drainage tube 3 of pump imports, after after impeller 7 rotates, energy increases, medium is again after stator 1 water conservancy diversion, and the water outlet of the pump on stator 1 is discharged in the pipe-line system outside pump.
The water outlet of pump is positioned on stator 1, the water outlet of pump and the as a whole structure of stator 1.
Claims (2)
1. a transverse core Structure of RCP, is characterized in that: the ingress of pump is provided with a drainage tube (3), and drainage tube is fixed on stator (1); Damage in impeller ring (4) is fixed on drainage tube (3), and stator wear ring (9) is fixed on stator (1); Impeller (7) is arranged in rotating shaft (8) by key (6), and is fixed on axle (8) by nut (5) by impeller (7); Together with stator (1) puts together on the support of motor (14), stator near waterexit end bottom adopt end socket (2) seal; Motor (14) is fixed on pressure vessel wall (15) by kingbolt (13), mother nut (11), taperliner (12).
