style="text-indent:25px">在實驗室氣路工程設(shè)計和安裝中，鋼木實驗臺建議采用集中送風(fēng)方式輸送高純氣體，具體如下：1.保持氣體純度，特殊氣瓶配備沖洗閥，以消除每次更換氣瓶時引入的雜質(zhì)，并確保管道末端的氣體純度。2.連續(xù)供氣，氣動控制系統(tǒng)可手動或自動切換氣缸，保證連續(xù)供氣。3.低電壓警告，當(dāng)氣壓低于報警限值時，報警裝置自動啟動報警。4.壓力穩(wěn)定性，系統(tǒng)采用兩級減壓（第1級由供氣控制系統(tǒng)調(diào)節(jié)，第二級由使用點的控制閥調(diào)節(jié)），以獲得非常穩(wěn)定的壓力。5.高效率，供氣控制系統(tǒng)可以充分利用氣缸內(nèi)的氣體，減少殘余氣體，降低燃?xì)獬杀尽?.操作方便，所有氣缸均集中在同一位置，減少了操作和安裝操作，節(jié)省了時間和成本。7.減少汽油瓶的租金，**供風(fēng)系統(tǒng)減少了所需氣缸的數(shù)量，從而節(jié)省了氣缸租賃和購買的成本。8.減少沸石的損失，有效控制氣體純度，減少了方形分子篩的使用（節(jié)約成本）。9.實驗室里沒有氣瓶。</p><p style="text-indent:25px">實驗室為什么要使用集中供氣系統(tǒng)？1.安全:即使仍然使用鋼瓶供氣，但鋼瓶被放置在工作區(qū)外的一個安全區(qū)域，使用者可以通過配備的遠(yuǎn)程切斷系統(tǒng)在緊急狀況下切斷氣體供應(yīng)；鋼瓶儲存區(qū)的合理布置可以保持可燃性容器和助燃性容器間的安全間距，工作場所附件不再有高壓設(shè)備，有毒或可燃?xì)怏w泄露的潛在危險也得以避免；鋼瓶的操作仍必須由培訓(xùn)合格的人員來操作以減少重大事故發(fā)生的機(jī)率。2.經(jīng)濟(jì)性：建一個集中的氣瓶間可以節(jié)省有限的實驗室空間，更換鋼瓶時不需要切斷氣體，節(jié)省了時間并保證了氣體的連續(xù)供應(yīng)。使用者只需管理較少的鋼瓶，支付較少的鋼瓶租金，因為使用同一氣體的所有使用點來自于同一個氣源。此種供應(yīng)方式較終會減少運(yùn)輸費用，減少退還給氣體公司的空瓶中的余氣量，使得鋼瓶管理更統(tǒng)一和規(guī)范。3.純度：可吹掃的減壓器面板可以保持氣體的指定純度，鋼瓶更換頻率的減少導(dǎo)致雜質(zhì)進(jìn)入系統(tǒng)的機(jī)率降低。4.工作流程：集中管道供應(yīng)系統(tǒng)可以將氣體出口放置在使用點處，這樣的話可以更合理的設(shè)計工作場所；通過監(jiān)控和報警系統(tǒng)也能夠更輕松地控制供氣過程。這樣，工作流程得到明顯的優(yōu)化。實驗室氣路集中供氣使更多的統(tǒng)一規(guī)范管理的圓柱體。</p><div

style="text-indent:25px">實驗室供氣需求:目前大多數(shù)實驗室中的各種分析儀器如氣相色譜儀、氣相色譜質(zhì)譜儀、液相色譜質(zhì)譜儀、原子吸收分光光度計、原子熒光光度計、等離子發(fā)射光譜儀、電感耦合等離子質(zhì)譜儀等都需要連續(xù)使用高純載氣和燃?xì)?，因此實驗室的安全、連續(xù)、穩(wěn)定運(yùn)行需要我們考慮如何將這些氣體供到各實驗室中放置的分析儀器。實驗室供氣現(xiàn)狀:目前我們可以用采用高壓鋼瓶、液體杜瓦瓶、集中供氣系統(tǒng)完成上述工作。同時，當(dāng)?shù)叵酪?guī)范建議甚至要求將主要的氣體源如鋼瓶、杜瓦瓶和液體儲槽放置在工作區(qū)外的指定區(qū)域，然后將氣體通過管道系統(tǒng)輸送至實驗室。但是考慮安全和效率因素，不考慮經(jīng)濟(jì)性因素，集中供氣系統(tǒng)是比較好的方式。實驗室氣路系統(tǒng)中，為了便于維修及更換閥件，管道與閥件的連接應(yīng)采用高壓雙卡套接頭連接。寧波實驗室氣路安裝</p><p
