The invention discloses a spherical
flue element
equivalent model thermotechnical waterpower experimental apparatus comprising a pressure-bearing component, an
electric heating component, an insulation component, a seal component, a
pressure measurement component and the like, and field
assembly and disassembly can be realized between the components. According to the spherical
flue element
equivalent model thermotechnical waterpower experimental apparatus, a banded fin thin rod bundle electric element is taken as an
equivalent model structure of the spherical
flue element, electrical heating method is realized, single-phase
water flow and
heat transfer experiment can be developed, and thermal-hydraulics of the spherical flue element can be reflected. The
pressure measurement component can be assembled and disassembled on spot,
consumables such as an O-shaped seal ring and a lead
pressure pipe are convenient to replace, thereby reducing loss and cost. A grid spacer plays a role in
transverse orientation for the banded fin thin rod bundle electric element, and a single-cone structure of the grid spacer can guide a plurality of the banded fin thin rod bundles to assemble, thereby reducing the difficulty of assembling and improving the efficiency of assembling.
Copper braid is adopted to connect a lower conducting element and a lower conductive contact to realize flexible connection, so that the problem caused by electric component
thermal expansion is effectively solved.
