利用水电相似原理设计了一种防砂筛管过流能力模拟试验装置,使筛管过流能力评价方法科学化、简易化。该装置可以实现不同筛管间过流能力对比试验、其他因素对筛管过流能力的影响试验、筛管周围压力场分布的测试试验。为防砂筛管过流能力测试、防砂筛管优选、防砂筛管优化设计提供了一种有效手段。
Based on the similarity principle of hydropower, a simulation test device for the overcurrent capacity of sand control screen was designed to make the evaluation method of screen overcurrent capability scientific and simple. The device can realize the comparison test of the over-current capacity between different screens, the influence test of other factors on the over-current capacity of the screen, and the test of the distribution of the pressure field around the screen. For the sand screen over-current capacity test, sand screen optimization, sand screen optimization design provides an effective means.
