介绍了一维表面温度分布的非接触测量仪器——扫描光电高温计的基本原理、结构、性能以及实用情况。扫描光电高温计的研制成功,使烧蚀模型表面温度测量从点温度测量拓展到一维温度分布测量,解决了突缩管壁面热分布的研究问题,测量了各种材料烧蚀模型驻点区温度分布曲线和不同材料平板模型在烧蚀试验中沿射流流向和径向的温度分布,并利用弓型导管装置对不同开槽型的石墨平板模型和喷有氧化锆隔热涂层的平板试件进行了温度场的测量。同时,还介绍了偏转装置与扫描光电高温计配合使用,一次开车试验可以测量不同位置上一维温度分布。
The non-contact measuring instrument of one-dimensional surface temperature distribution is introduced. The basic principle, structure, performance and practicality of scanning photoelectric pyrometer are introduced. The successful development of scanning photoelectric pyrometer makes the ablation model surface temperature measurement from point temperature measurement to one-dimensional temperature distribution measurement, solves the research problem of the heat distribution on the wall of the shrink tube, and measures the stagnation point area Temperature distribution curves and temperature distribution along the jet flow direction and radial direction in the ablation test of the slab model with different materials. By using the bow-shaped conduit device, the different slotted graphite slab model and the flat plate test sprayed with the zirconia thermal insulation coating The temperature field was measured. At the same time, the deflecting device is also described in combination with the scanning photoelectric pyrometer. A driving test can measure the one-dimensional temperature distribution in different locations.
