原裝德國E+H渦街流量計安裝*要點(diǎn)
德國恩德斯豪斯E+H旗下產(chǎn)品，使用比較廣，全國各地都有用到，所以我們要了解下E+H產(chǎn)品的一些知識，今天，我們給大家介紹的是E+H渦街流量計安裝應(yīng)注意的10個要點(diǎn)，希望能對客戶朋友們有所幫助。
E+H渦街流量計安裝注意的要點(diǎn)：
1、合理選擇安裝場所和環(huán)境。
避開強(qiáng)電力設(shè)備，高頻設(shè)備，強(qiáng)電源開關(guān)設(shè)備；避開高溫?zé)嵩春洼椛湓吹挠绊?，避開強(qiáng)烈震動場所和強(qiáng)腐蝕環(huán)境等，同時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、管道采取減振動措施。
傳感器盡量避免安裝在振動較強(qiáng)的管道上，特別是橫向振動。若不得已要安裝時，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。
測量氣體流量時，若被測氣體中含有少量的液體，傳感器應(yīng)安裝在管線的較高處。
測量液體流量時，若被測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。
測量氣體流量時，傳感器可以安裝在垂直管道上，流向不限。若被測氣體中含有少量的液體，氣體流向應(yīng)由下向上。
測量液體流量時，液體流向應(yīng)由下向上：這樣不會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。
無論測量何種流體，傳感器可以在水平管道上側(cè)裝，特別是測量過熱蒸汽，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量一般氣體、過熱蒸汽。可用于測量飽和蒸汽，適用于測量高溫液體或需經(jīng)常清洗管道的情況。
9．傳感器在有保溫層管道上的安裝。
測量高溫蒸汽時，保溫層zui多不能超過支架高度的三分之一。
10．測壓點(diǎn)和測溫點(diǎn)的選擇。
根據(jù)測量的需要，需在傳感器附近測量壓力和溫度時，測壓點(diǎn)應(yīng)在傳感器下游的3-5D處，測溫點(diǎn)應(yīng)在傳感器下游的6-8D
