一、产品简介
SL-2098型埋地管道外防腐层状况检测仪在不挖开覆土的情况下,能够方便而准确地查出地下金属管道的位置、走向、深度、防腐层破损点、破损点的个数、破损点间的距离、破损点的大小等功能。用途:根据SYJN4029-88和GJJ33089标准对管道进行验收;对新铺设的管道进行竣工验收;根据规程对管道进行定期检测,确定阴极保护效果;对主管线上的分支进行定位;对旧管道进行检测,确定该管段是否需要大修;对施工区段开挖破土前进行地下管线分布检查,防止施工时破坏地下油、气、水、电等管线。
二、检测原理
探测走向和埋土深度的原理及方法:向地下管道发送特定的高频调制信号通过探测地下管道的磁场来确定地下管道的位置、走向和深度。
方法有峰值法和零值法。
检测原理及方法:向地下管道发送特定的高频调制信号,在地下管道防腐层破损点处与大地形成回路,并向地面辐射,在破损正上方辐射信号强,根据这一原理找出管道防腐层的破损点。
采用“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,示值大,从而准确找到漏蚀点。
三、 产品特点
★采用全新数字滤波技术,可设定漏点的范围,自动记录漏点的个数,并显示漏点间距离;
★具有多种探测方式,并可自动转换。发射机电池电压不足及自动关机前, 向接收机发出提示信号,关机时数值自动保存。
★能够自动测出管道的对地电阻,输出信号调制高频报警信号,抗干扰能力。发射机输出功率可随着检测距离增加自动调节,检测完毕发射机自动关机,提高了仪器的检测效果,延长了电池的使用时间和寿命。
