The invention provides a rod bundle channel flow pressure measuring test device, which comprises a
water storage tank, a pressure measuring body, and a
centrifugal pump, a regulating valve and a
thermometer sequentially connected with the
water storage tank through a pipeline, wherein the pressure measuring body comprises a rod bundle channel
barrel, a rod bundle channel formed by rod bundles arranged in the rod bundle channel
barrel; the upper ends of the rod bundles are connected with a high-accuracy rotating disk arranged on a rotating table support through a coupler; two body pressure ports formed up and down are formed in the rod bundle channel
barrel; a pressure guiding port is formed in each rod bundle of the rod bundle channel; a sealing rubber plug is arranged at the lower end of each rod bundle; a fast adapter is arranged at the upper end of each rod bundle;
pressure difference transmitters are respectively arranged between each pressure guiding port and each fast adapter as well as between the two body pressure ports. The rod bundle channel flow pressure measuring test device provided by the invention can simulate single-phase flow in a reactor rod bundle channel so as to research a resistance characteristic of the rod bundle channel, and is simple in structure, low in cost, accurate and convenient to acquire data, and wide in research working condition range.
