Embodiment Construction

[0010] Such as figure 1 The present invention shown is a static fluid test device for a turbogenerator. The entire device is based on the base plate 1, and the rotor model 2 is positioned on the base plate 1 through the seam. This positioning method ensures the relative position of the rotor model Consistency between the relationship and the real machine. In the length direction, one end is sealed with a sealing plate 3, the other end is fixed with the rotor fan connection section 4 with bolts, and the other end of the rotor fan connection section 4 is connected with the rotor fan 5 with bolts. Such a connection method provides a pressure source for the rotor model 2, which simulates the pressure generated by the real fan and rotor rotation, and provides conditions for the rotor test. After the stator model 6 is assembled, two side plates 8 are welded on both sides of the stator model 6 in the width direction of the stator simulation base 7 for positioning and sealing in the ...

Abstract

The invention relates to a turbogenerator static fluid testing device. The whole device adopts a foundation plate as basis; a rotor model is positioned on the foundation plate through a stop opening; one end of the rotor model is sealed by a sealing plate, and the other end of the rotor model is fixed with a rotor fan connection section by a bolt; the other end of the rotor fan connection section is connected with a rotor fan by a bolt. The stator model is positioned on the rotor model through the stop opening; then a baffle plate at the end of the stator model is welded by the drawing; finally, two ends of the stator fan connection section are respectively connected with wind inlets of the stator fan and the stator model by bolts. The turbogenerator static fluid testing device simulates the structure and flow field features of a real machine, keeps the consistency of the characteristics of solid surface materials contacted with fluids in runners with the real machine, and realizes the innovation of the cooling manner of turbogenerators.

Description

Technical field: [0001] The invention relates to a static fluid test device for a steam turbine generator. Background technique: [0002] Domestic large-scale nuclear power half-speed turbogenerator technology mainly relies on foreign technology transfer, and the design of the ventilation system is quite difficult, especially the selection of cooling methods for the rotor will become a difficult point in the design. The existing rotor wind path has complex structure and relatively large resistance. The present invention carries out the research on the static fluid test device of the steam turbine generator, simulates the characteristics of the flow field of the cooling medium of the motor, and selects a better ventilation and cooling structure than the current one through the comparative analysis of the test data, which is the development of the ventilation system of the large nuclear power half-speed steam turbine generator Play an effective guiding role. Invention conte...
