Pipeline pit cavitation erosion test device

The invention relates to a pipeline pit cavitation erosion test device, which comprises an experiment pipe made of transparent materials. The two ends of the experiment pipe are connected into a liquid circulation mechanism through a first reducer pipe and a second reducer pipe respectively, the two ends of the experiment pipe are connected with the small-diameter ends of the first reducer pipe and the second reducer pipe respectively, a pore plate is arranged in the experiment pipe, and the hole surface of a through hole of the hole plate is provided with a pit. The test device can be used for researching the development and collapse conditions of cavitation bubbles at a pit. 本发明涉及一种管道凹坑空蚀实验装置，包括由透明材质制成的实验管,实验管两端分别通过第一变径管和第二变径管接入液体循环机构，实验管两端分别与第一变径管和第二变径管直径较小的端部连接，所述实验管内设孔板，孔板的通孔的孔面上开设有凹坑，本发明的实验装置能够研究空化气泡在凹坑处的发展和溃灭情况。
