摘　　要：管道内检测中具有速度控制功能的内检测器至关重要,然而在内检测器控速测试环节,由于全域实验环境难以建立,导致内检测器速度精准测量受限,进而影响了速度控制系统的深入研发与应用。文中提出了一种替代方案,即通过测试推力模拟测试速度,设计了一套管道内检测器速度控制系统测试装置。该装置通过空压机向进气口注入特定流量和压力的压缩空气,以模拟管道介质对内检测器的推力。利用该测试装置,对采用2种控制算法的速度控制系统进行了测试。测试结果表明:该装置能够有效评价速度控制系统的动态调节过程、气动推力和响应时间等关键性能指标,反映了速度控制系统的性能,并验证了该测试方法的有效性。文中为内检测器速度控制系统的测试提供了一种实验方法,有助于推动相关技术的研发和应用。In the field of internal inspection,internal detectors with speed control capabilities are crucial.However,during the speed control testing phase of the internal detectors,the establishment of a full-domain experimental environment is challenging,which limits the precise measurement of detector speeds,thereby affecting the in-depth development and application of speed control systems.This study proposed an alternative approach by testing thrust to simulate speed and designed a testing device for the speed control system of pipeline internal detectors.The device simulated the thrust of the pipeline medium on the internal detector by injecting compressed air of specific flow and pressure into the intake through an air compressor.Using this testing device,speed control systems with two control algorithms were tested.The test results indicate that the device can effectively evaluate key performance indicators such as the dynamic adjustment process,aerodynamic thrust,and response time of the speed control system,reflecting the performance of the speed control system and validating the effectiveness of this testing method.This research provides a experimental method for testing the speed control systems of internal detectors,which is conducive to promoting the deve-lopment and application of related technologies.
