【摘要】:管道檢測器利用管道內(nèi)介質(zhì)產(chǎn)生的壓力實現(xiàn)自運行,完成對管道缺陷的檢測。為保證檢測器的檢測精度,要求其運行速度不高于5 m/s。由于天然氣管道介質(zhì)流速過快,提出了搭載速度控制裝置調(diào)節(jié)檢測器運行速度的方法,介紹了速度控制裝置工作原理,研制了扇葉型和錐筒型兩種通過控制泄流通道面積來調(diào)節(jié)檢測器運行速度的速度控制裝置,通過將里程輪提供的速度信號與控制程序預設(shè)速度區(qū)間進行實時對比,利用電機提供的驅(qū)動力控制速度控制裝置的運行,實現(xiàn)對檢測器運行速度的實時調(diào)控,將速度調(diào)節(jié)至預設(shè)區(qū)間內(nèi)。該裝置通過了試驗與工業(yè)化應(yīng)用,工作正常,可滿足工業(yè)現(xiàn)場工況條件。
[Abstract]:The pipeline detector realizes self-operation by using the pressure generated by the medium in the pipeline to complete the detection of pipeline defects. In order to ensure the detection accuracy of the detector, the running speed of the detector is not higher than 5 m / s. Because the medium velocity of natural gas pipeline is too fast, the method of carrying speed control device to adjust the running speed of detector is put forward, the working principle of speed control device is introduced, and two kinds of speed control devices, fan blade type and cone tube type, which adjust the running speed of detector by controlling the area of discharge channel, are developed, and the speed signal provided by odometer is compared with the preset speed range of control program in real time. The driving force provided by the motor is used to control the operation of the speed control device to realize the real-time control of the running speed of the detector and adjust the speed to the preset range. The device has passed the test and industrial application, and works normally, which can meet the working conditions of the industrial field.
