摘要
传统的投产前管道测径方法存在检测周期长、人力物力消耗大、可靠性差等问题。为此,研发了一种新型投产前管道智能测径检测器,该设备的机械主体由筒体、皮碗、变形探头臂及里程轮组成,电气主体由记录仪、电池组、标记器及变形传感器组成。投产前管道智能测径检测器主要依靠空压机作为动力源,在不建立背压的管内环境下运行,并需解决不稳定的运行状态造成的检测数据丢失、信号失真等问题。现场实际应用结果表明:该装置能够在较短时间内快速发现、量化和定位站间管道存在的变形,从而大大缩短管道的施工工期,为管道验收提供科学依据。(图3,表1,参8)。
Traditional caliber method for Pre-commissioning pipeline has shortcomings such as long caliber period, high manpower and material resources consumption and low reliability. To solve this problem, a new smart calibre detector for Pre-commissioning pipeline has been developed. The main mechanical part of this device consists of cylinder, rubber cup, deformation probe ann and odometer wheels, while the main electric part is composed of recorder, battery array, marker and deformation sensor. This smart calibre detector, mainly using air compressor as power source and operating under the environment of non-back pressure in pipeline, has to overcome problems like loss of detection data and signal distortion caused by unsteady operation. The practical application in field shows that this device can quickly find out, quantify and locate the deformation points in pipe in a short time, and thus greatly reduce the construction period and provide a scientific basis to the pipeline's acceptance.
