[0002] At present, there are only a few large companies in the world that can develop and develop large-scale turbogenerators. At the same time, most of the axial flow fans used in the development process are entrusted to other companies for development, or traditional axial flow fans are used in various new types of steam turbines. In the turbine generator, there is no proprietary model test device for targeted development

The invention relates to an axial-flow fan model testing device of a steam turbo-generator, which is formed by a simulate section device and a supply air pipeline, the simulate section device is formed by arranging shaft coupling at the a main shaft output end of a frequency control three-phase asynchronous motor, the shaft coupling is connected with a torque sensor, the other end of the torque sensor is connected with the shaft coupling, a guide bearing is located in a wind tunnel, and a wind guide ring is mounted in the front of a testing blade. By mounting a new designed model axial-flow fan in the wind tunnel via the device, measuring the flow rate, pressure difference and efficiency of the fan in working sites and nearby the working sites, selecting the optimal blade shape, operation requirements of the steam turbo-generator can be met, and the efficiency is enabled to be the highest simultaneously, thereby obtaining an optimal axial-flow fan which is engaged with the steam turbo-generator, and increasing the efficiency of the turbo-generator.
Description
Technical field: [0001] The invention relates to a model test device for an axial flow fan of a steam turbine generator. Background technique: [0002] At present, there are only a few large companies in the world that can develop and develop large-scale turbogenerators. At the same time, most of the axial flow fans used in the development process are entrusted to other companies for development, or traditional axial flow fans are used in various new types of steam turbines. In the turbine generator, there is no proprietary model test device for targeted development. Invention content: [0003] The object of the present invention is to provide a model test device for measuring the pressure head and flow characteristics of the fan, and simultaneously measuring the efficiency of the fan operating in different working conditions to achieve the purpose of optimization. The technical solution of the present invention is: a turbo-generator axial flow fan model test device, whic...
