原裝德國(guó)E+H渦街流量計(jì)安裝*要點(diǎn)
德國(guó)恩德斯豪斯E+H旗下產(chǎn)品，使用比較廣，全國(guó)各地都有用到，所以我們要了解下E+H產(chǎn)品的一些知識(shí)，今天，我們給大家介紹的是E+H渦街流量計(jì)安裝應(yīng)注意的10個(gè)要點(diǎn)，希望能對(duì)客戶朋友們有所幫助。
E+H渦街流量計(jì)安裝注意的要點(diǎn)：
1、合理選擇安裝場(chǎng)所和環(huán)境。
避開(kāi)強(qiáng)電力設(shè)備，高頻設(shè)備，強(qiáng)電源開(kāi)關(guān)設(shè)備；避開(kāi)高溫?zé)嵩春洼椛湓吹挠绊?，避開(kāi)強(qiáng)烈震動(dòng)場(chǎng)所和強(qiáng)腐蝕環(huán)境等，同時(shí)要考慮安裝維修方便。
2、上下游必須有足夠的直管段。
若傳感器安裝點(diǎn)的上游在同一平面上有二個(gè)90。彎頭，則：上游直管段≥25D，下游直管段≥5D 。
若傳感器安裝點(diǎn)的上游在不同平面上有二個(gè)90。彎頭，則：上游直管段≥40D，下游直管段≥5D 。
調(diào)節(jié)閥應(yīng)安裝在傳感器的下游5D以外處，若必須安裝在傳感器的上游，傳感器上游直管段應(yīng)不小于50D，下游應(yīng)有不小于5D。
3、安裝點(diǎn)上下游的配管應(yīng)與傳感器同心，同軸偏差應(yīng)不小于0.5DN。
4、管道采取減振動(dòng)措施。
傳感器盡量避免安裝在振動(dòng)較強(qiáng)的管道上，特別是橫向振動(dòng)。若不得已要安裝時(shí)，必須采取減振措施，在傳感器的上下游2D處分別設(shè)置管道緊固裝置，并加防振墊。
5．在水平管道上安裝是流量傳感器zui常用的安裝方式。
測(cè)量氣體流量時(shí)，若被測(cè)氣體中含有少量的液體，傳感器應(yīng)安裝在管線的較高處。
測(cè)量液體流量時(shí)，若被測(cè)液體中含有少量的氣體，傳感器應(yīng)安裝在管線的較低處。
6．傳感器在垂直管道的安裝。
測(cè)量氣體流量時(shí)，傳感器可以安裝在垂直管道上，流向不限。若被測(cè)氣體中含有少量的液體，氣體流向應(yīng)由下向上。
測(cè)量液體流量時(shí)，液體流向應(yīng)由下向上：這樣不會(huì)將液體重量額外附加在探頭上。
7、傳感器在水平管道的側(cè)裝。
無(wú)論測(cè)量何種流體，傳感器可以在水平管道上側(cè)裝，特別是測(cè)量過(guò)熱蒸汽，飽和蒸汽和低溫液體，若條件允許采用側(cè)裝，這樣流體的溫度對(duì)放大器的影響較小。
8．傳感器在水平管道的倒裝。
一般情況下不推薦用此安裝方法。此安裝方法不適用于測(cè)量一般氣體、過(guò)熱蒸汽。可用于測(cè)量飽和蒸汽，適用于測(cè)量高溫液體或需經(jīng)常清洗管道的情況。
9．傳感器在有保溫層管道上的安裝。
測(cè)量高溫蒸汽時(shí)，保溫層zui多不能超過(guò)支架高度的三分之一。
10．測(cè)壓點(diǎn)和測(cè)溫點(diǎn)的選擇。
根據(jù)測(cè)量的需要，需在傳感器附近測(cè)量壓力和溫度時(shí)，測(cè)壓點(diǎn)應(yīng)在傳感器下游的3-5D處，測(cè)溫點(diǎn)應(yīng)在傳感器下游的6-8D
