一、产品简介
SL-5型地下管道防腐层探测检漏仪能在不挖开复土的情况下,方便而准确地查出地下管道的走向、深度和绝缘防腐层的漏蚀点的位置,使整个管道地表面不再屡遭到处开搪破土之苦,是油田、化工、输油、输气、水电等部门为保证地下管道防腐层的施工质量检查和维修检查的一种便捷、率的检测仪器。
二、检测原理
通过向地下管道发送出1KHz的电磁波信号,探测仪利用探头与磁力线地平面垂直相切时,收到的信号小(几乎为零)的原理来测定管道的走向和深度。
通过向地下管道发送一个交流信号源,当地下管道防腐层被腐蚀后,该处金属部分与大地相短路,在漏点处形成电流回路,将产生的漏点信号向地面辐射,并在漏点正上方辐射信号大,根据这一原理就可准确地找到漏蚀点。
检漏方法,我们采用的是“人体电容法”,就是用人体做检漏仪的感应元件,当检漏员走到漏点附近时,检漏仪开始有反应,当走到漏点正上方时,喇叭中的声音响,表头指示大,从而准确找到漏蚀点。

SL-5 underground pipeline leak detection of anti-corrosion layer can be in without digging, convenient and accurate underground pipeline towards, depth and insulating coating of corrosion and leakage point precise position, so that the entire pipeline surface no longer repeated everywhere on soft ground, is the oil field, chemical, oil, gas, electricity and other departments in order to ensure the construction quality of underground pipeline anticorrosion layer inspection and repair inspection as a convenient, efficient detection apparatus.
二、检测原理
In two, the detection principle
通过向地下管道发送出1KHz的电磁波信号,探测仪利用探头与磁力线地平面垂直相切时,收到的信号小(几乎为零)的原理来测定管道的走向和深度。
Through to the underground pipeline to send out 1KHz electromagnetic wave signal, detector using probe and magnetic field vertical tangent, received signal minimum (almost to zero ) of the principle to detect pipe direction and depth.
通过向地下管道发送一个交流信号源,当地下管道防腐层被腐蚀后,该处金属部分与大地相短路,在漏点处形成电流回路,将产生的漏点信号向地面辐射,并在漏点正上方辐射信号大,根据这一原理就可准确地找到漏蚀点。
Through to the underground pipeline to send an AC signal source, when the underground pipeline anticorrosion layer is etched, the metal part and the land phase short circuit, the leakage current circuit is formed, the leakage signal to ground radiation, and at the point just above the maximum radiation signal, according to this principle can accurately locate the leak corrosion spot.
检漏方法,我们采用的是“人体电容法”,就是用人体做检漏仪的感应元件,当检漏员走到漏点附近时,检漏仪开始有反应,当走到漏点正上方时,喇叭中的声音响,表头指示大,从而准确找到漏蚀点。
Leak detection method, we are using the " body capacitance method", is to use human detector sensing element, when the detection member went to the point near, leak detector responses to, when go to the point above, horn of rattles most, header indicating the maximum, so as to find leakage corrosion.
