Abstract
The invention relates to an auxiliary impeller hydraulic model testing device which is composed of a suction casing, a discharge casing, an auxiliary impeller assembly, a shaft sleeve, a locking nut, a key, a main bolt assembly, a pump cover, packing, a packing gland, a shaft sleeve, shafts, a bearing suspension component, a set of fasteners, a coupling assembly, a motor and a base. By the adoption of the device, an efficiency test, a cavitation test, various hydraulic performance tests and force characteristic tests for an auxiliary impeller hydraulic model of a matching shielded motor of a novel small-sized nuclear power station main pump set can be completed, and an important technical base and a powerful guarantee are provided for model selection of an auxiliary impeller of the shielded motor and optimization design of hydraulic parts.
Description
Technical field: the present invention relates to a kind of auxiliary impeller hydraulic model test device.
Background technique: International Atomic Energy Agency proposes the concept of innovation type reactor and modularization construction the beginning of this century, the reactor of definition electric power below 300,000 kilowatts is small-sized heap.Small-sized heap and large nuclear-power have their own characteristics each in technology and applying, complement one another.For satisfied different demand, the small-sized heap of modular type of safe, reliable, the viable economically and anti-nuclear proliferation of the positive encourage growth of IAEA.The Nuclear Power developed country, while development large nuclear-power unit, is is also all actively researching and developing multipurpose modular type Small reactor.
In recent years, 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, 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 closely drives to maturity stage.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 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 full and has closed.Following nuclear power demand will transfer to the developing countries and energy starved countries and regions gradually, and 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.The Pump for Medium and Small Power Generating Set simply reduced from capacity and size is then difficult to the demand meeting user due to the reason such as Security and the economical efficiency of scale.Because this small cores main pump technology small-sized still belongs to blank at home, therefore small cores main pump unit necessary electromotor is inner extremely urgent with the R&D work of auxiliary impeller.
Summary of the invention: the object of this invention is to provide and a kind ofly test the auxiliary impeller hydraulic model test device that the inner auxiliary impeller hydraulic model of Small nuclear power plant main pump motor carries out efficiency test, cavitation experiment, total external characteristic test and force characteristic test, to test every hydraulic performance of water pump hydraulic model.Technological scheme of the present invention is: a kind of auxiliary impeller hydraulic model test device suction casing (1) and pump cover (10) are fixed on Spit Section (2) by rod bolt assembly (9); Impeller assembly (3) is fixed on axle sleeve (4) by junction of the edges of two sheets of paper screw (8); Axle sleeve (4) is positioned on axle (14) by axle sleeve (7) and key (6), and impeller assembly (3) and axle sleeve (4) are fixed on axle (14) by locking nut (5); Bearing suspension parts (13) are arranged on axle (15), and bearing suspension (16) is fixed on pump cover (10) by suspension bolt fastener (11); Gland (13) adopts gland bolt fastening piece (14) to be pressed in the chamber of pump cover (10) by filler (12); Be connected by coupling assembly (17) between axle (15) and motor (8).
Working procedure of the present invention is:
Motor (18) is rotated through coupling assembly (17) band moving axis (15), axle (15) rotarily drives auxiliary impeller assembly (3) and rotates, rotated by auxiliary impeller assembly (3) and the suction casing (1) of water from testing apparatus is sucked, then discharged outside testing apparatus by the Spit Section (2) of testing apparatus.
Technological merit of the present invention is:
1. feature of the present invention is: this testing apparatus structure is simple, and the component that pumping section is divided are considerably less, and the suction casing of the pump housing and water exit end and pump cover are respectively split manufacture, and machining process is simple.
2. feature of the present invention is: as shown in Figure 2, and what the survey of this testing apparatus was is small flow, high-lift auxiliary impeller hydraulic model, therefore if any similar Parametric Pumping, namely this apparatus structure can be used as product structure and use.
3. feature of the present invention is: the bearing suspension parts (13) of this testing apparatus are the bearing suspension structures applying ripe petrochemical process pump, structural stability, good reliability.
Accompanying drawing illustrates:
Fig. 1 is a kind of auxiliary impeller hydraulic model test apparatus structure schematic diagram of the present invention
Fig. 2 is the parameter list of auxiliary impeller hydraulic model
