我們通過相應(yīng)的理論計算和大量的工程實踐，**雙密封液壓聲測管。**雙密封液壓聲測管在承口端端部設(shè)計了兩個凸槽，凸槽內(nèi)配有密封圈，安裝時將聲測管的插口端插入承口端10cm，然后用**液壓鉗同時對兩個凸槽進行擠壓，被擠壓部位的管材受力后收縮變形，兩個凸槽之間的外層管材深陷入內(nèi)層管材，從而有效實現(xiàn)了聲測管的可靠連接；同時橡膠材質(zhì)的密封圈在受擠壓后變形貼服在兩層管材之間，起到了極為良好的雙保險密封作用。**雙密封液壓聲測管的優(yōu)點主要是充分考慮到聲測管在使用中所涉及的各種要素，從各方面達到國內(nèi)乃至世界前列的性能。指標(biāo)標(biāo)準(zhǔn)密封性連接可靠性抗扭矩性能套接長度內(nèi)壓外壓行業(yè)標(biāo)準(zhǔn)1mpa保壓1min4mpa保壓1min接頭處能承受3KN的拉拔力接頭處能承受扭力矩120N·m≥8mm企業(yè)標(biāo)準(zhǔn)2mpa保壓1min4mpa保壓2min接頭處能承受6KN的拉拔力接頭處能承受扭力矩180N·m≥10mm。

style="text-indent:25px">聲測管材質(zhì)的選擇，以透聲率較大、便于安裝及費用較低為原則。聲脈沖從發(fā)射換能器發(fā)出，通過耦合水到達水和聲測管管壁的界面，再通過管壁到達聲測管管壁與混凝土的界面，穿過混凝土后又需穿過另一聲測管的兩個界面而到達接收換能器。因此，聲測管形成4個界面，每個界面的聲能透過系數(shù)可按下式計算：式中：——某界面的聲能透過系數(shù)；——界面兩側(cè)介質(zhì)的聲阻抗率發(fā)射和接收換能器之間4個界面的總透聲系數(shù)為聲阻抗率較低，用做聲測管具有較大的透聲率，通?？捎糜谳^小的灌注樁，在大型灌注樁中使用時應(yīng)慎重，因為大直徑樁需灌注大量混凝土，水泥的水化熱不易發(fā)散：鑒于塑料的熱膨脹系數(shù)與混凝土的相差懸殊，混凝土凝固后塑料管因溫度下降而產(chǎn)生徑向和縱向收縮，有可能使之與混凝土局部脫開而造成空氣或水的夾縫，在聲通路上又增加了更多反射強烈的界面，容易造成誤判。聲測管的直徑，通常比徑向換能器的直徑大l0mm即可，常用規(guī)格是內(nèi)徑50-60mm。管子的壁厚對透聲率的影響很小，所以，原則上對管壁厚度不作限制，但從節(jié)省用鋼量的角度而言，管壁只要能承受新澆混凝土的側(cè)壓力，則越薄越省。云南聲測管廠家，云南貿(mào)軒商貿(mào)有限公司。昆明鉗壓式聲測管廠家直銷13888426708</p><p
