因暖氣管道的水溫較高，一般在60－90度，所以漏水必然導(dǎo)致排水溝內(nèi)的水溫或地面的水溫升高，測溫法就是按照這個原理進(jìn)行的。通常以為一旦漏水，排水溝上就會冒熱氣，其實(shí)不盡然，只有排水溝有落差或排水溝污水表面無油污覆蓋時才會出現(xiàn)。只有通過測量污水的溫度或地面溫度才能準(zhǔn)確發(fā)現(xiàn)溫度的變化。測量時首先測量排水溝里的污水溫度，然后用紅外線測溫儀沿小區(qū)管道的走向測量地面溫度，進(jìn)行普查，找出可疑點(diǎn)。測量污水溝的污水溫度可以按照先主排水溝，后支排水溝的原則進(jìn)行。正常華北地區(qū)排水溝的水溫在20度以下，如超出此范圍證明有異常，可以沿水流的方向查找，越接近漏水點(diǎn)溫度越高。因?yàn)槲覈煌貐^(qū)的室外溫度相差較大，所以不同地區(qū)排水溝里的污水溫度也不同，差別較大。對地面的溫度普查也很重要，因?yàn)橛械穆┧灰欢魅肱潘疁?，如果測量地面某一位置的溫度與其它位置的溫度差別較大，就可以將探頭插入土內(nèi)（路面較硬的地方可以用沖擊鉆打孔），根據(jù)埋地管道的深度確定探頭插入的深度。越接近漏水點(diǎn)處的水溫越高，基本接近暖氣管道里的水溫。根據(jù)測量暖氣管道周圍土的溫度的高低來決定打孔的位置和打孔密度，找出準(zhǔn)確的位置。</p><div

工作原理如下供水管道產(chǎn)生漏水時，噴出管道的水與漏口摩擦，以及與周圍介質(zhì)等撞擊，會發(fā)生不同頻率的振動,供熱管道查漏儀，由此產(chǎn)生漏水聲。在管道破損處，水漏損時會構(gòu)成聲波并以正弦曲線的方法向管道兩側(cè)流傳，并引起管道振動，同時，在決裂處急速噴出的水流，沖擊管道周圍的介質(zhì)，從而產(chǎn)生存在特別頻率的漏水音，由四周介質(zhì)及管道傳布到地面。查明供水管網(wǎng)中的漏水點(diǎn)，個別用探測漏水點(diǎn)的漏水聲法，這就是檢漏的根本原理。漏水聲的品種通?？煞譃槿N：①漏口摩擦聲：是指噴出管道的水與漏口摩擦產(chǎn)生的聲音，其頻率通常為300～2500Hz，并沿管道向遠(yuǎn)方傳播，傳播間隔通常與水壓﹑管材﹑管徑﹑接口﹑漏口外形大小等有關(guān)。在必定范疇內(nèi)，可在閘門﹑消火栓等裸**聽測到漏水聲。②水頭撞擊聲：是指噴出管道的水與周圍介質(zhì)撞擊產(chǎn)生的聲音，并以漏斗情勢通過泥土向地面擴(kuò)散，在地面可用檢漏儀或聽音桿聽測到，其頻率通常為100～1500Hz之間。自來水漏水檢測儀③介質(zhì)摩擦聲：是指噴出管道的水帶動周圍粒子(如土粒，沙粒等)彼此碰撞摩擦產(chǎn)生的聲音，其頻率較低，當(dāng)把聽音桿插到地下漏點(diǎn)鄰近時，可聽測到，這為漏點(diǎn)***確認(rèn)供給了根據(jù)。當(dāng)初常用檢漏裝備就是捕獲這三種聲音。</p></p><br
