防砂筛管水压试验装置
摘要：
本发明提供了一种防砂筛管水压试验装置，用于测试防砂筛管抗外压强度，所述防砂筛管水压试验装置包括：试验筒，具有容纳防砂筛管的密闭空腔；承力组件，包括：包围在所述防砂筛管侧向的弹性密封套、以及封闭所述防砂筛管两端的筛管堵头；应变测试组件，包括：设置在所述防砂筛管内侧面上的应变传感器。通过防砂筛管水压试验装置，防砂筛管整个管体受到均匀径向力作用，测试方法十分科学；所测得的液压数值就是筛管实际抗外压强度值，不需要换算。本发明结构简单、科学合理，能有效的测量防砂筛管抗外挤强度。
摘要（英）：

The invention provides a sand prevention screen tube hydraulic test apparatus. The apparatus is used for testing the outer pressure resistance of a sand prevention screen tube, and the sand prevention screen tube hydraulic test apparatus comprises: a test cylinder having a closed cavity for accommodating the sand prevention screen tube; a bearing assembly comprising an elastic sealing sleeve surrounding the side direction of the sand prevention screen tube, and screen tube plugs sealing two ends of the sand prevention screen tube; and a strain test assembly comprising a strain sensor arranged on the inner side surface of the sand prevention screen tube. The sand prevention screen tube hydraulic test apparatus allows the uniform radial force to be applied to the whole sand prevention screen tube and a test method to be highly scientific; and a hydraulic value obtained in the invention is the practical outer pressure resistance of the screen tube, and does not need conversion. The sand prevention screen tube hydraulic test apparatus has the advantages of simple, scientific and reasonable structure, and effective measurement of the outer pressure resistance of the sand prevention screen tube.
