style="text-indent:25px">實(shí)驗(yàn)室氣路工程流量的調(diào)節(jié)形式：1、流量調(diào)不上去：(1)直觀檢查：首先檢查儀器系統(tǒng)是否有明顯的漏氣聲。在儀器系統(tǒng)氣路有較大的泄漏發(fā)生時(shí)，很可能導(dǎo)致流量調(diào)不上去。如果聽不到漏氣聲則轉(zhuǎn)入進(jìn)行。(2)查漏：聽到有漏氣聲之后，可依照聲音發(fā)出的方向而逐步定位。此時(shí)可利用皂液的涂抹進(jìn)一步確定漏氣的發(fā)生處。找到原因后及時(shí)堵漏。(3)柱前壓觀察：觀察柱前壓指示表的數(shù)值大小，可迅速判斷是氣源引起的故障，還是儀器內(nèi)部氣路堵塞及損傷造成的。如果是柱前壓太低(精確地說是比正常流量操作時(shí)的預(yù)定壓力值低)，則說明氣源需要檢查;如果柱前壓正常則需要檢查儀器的內(nèi)部氣路。(4)鋼瓶高壓檢查：打開鋼瓶閥后，觀察高壓表指示，壓力應(yīng)在1~15MPa之間。如果壓力在1MPa以下，停用該鋼瓶，換氣;如壓力值在合適的范圍內(nèi)，說明鋼瓶壓力正常。(5)減壓閥上低壓輸出檢查：調(diào)節(jié)減壓閥看鋼瓶上低壓表指示能否調(diào)到0.25~0.6MPa之間。如果正常，可懷疑氣路過濾接頭有堵塞或者是儀器上的穩(wěn)定閥有問題，此時(shí)應(yīng)按照(6)來進(jìn)行;如低壓值不正常，則說明減壓閥有問題，需進(jìn)行修理。實(shí)驗(yàn)室氣路集中供氣系統(tǒng)特點(diǎn)：安全。寧波實(shí)驗(yàn)室氣路安裝制造商</p><p style="text-indent:25px">實(shí)驗(yàn)室供氣系統(tǒng)是一套長期使用的設(shè)備，必然存在維護(hù)問題。寧波實(shí)驗(yàn)室氣路安裝制造商</p><p style="text-indent:25px">針對(duì)過去使用中存在的問題，現(xiàn)代實(shí)驗(yàn)室對(duì)載氣的使用環(huán)境進(jìn)行了改變，即“集中供氣系統(tǒng)”，即將使用氣體（以下簡稱載氣）集中貯存，然后通過壓差的原理將氣體經(jīng)過金屬或其他材質(zhì)管路送至用氣點(diǎn)。其優(yōu)點(diǎn)主要有以下幾點(diǎn)：? 1、首先解決氣瓶的放置問題。氣瓶間的位置如果可能盡量位于與實(shí)驗(yàn)室相對(duì)**的房間，如果與實(shí)驗(yàn)室在同一大樓內(nèi)，則氣瓶間的位置要盡量位于人流較少并且**的房間，這種方式可使氣瓶與工作人員及儀器完全隔離，即使有害氣體有泄漏，也不會(huì)發(fā)生直接傷害。? 2、其次氣體混合的問題。將所有載氣氣瓶根據(jù)氣體性質(zhì)分別集中在一個(gè)氣瓶間中（其實(shí)主要是將易燃易爆氣體（如H2、天燃?xì)?、乙炔等）與助燃?xì)怏w分開存貯）。? 3、再次是解決氣瓶壓力的問題。每種氣體可以將多瓶氣體并聯(lián)然后通過一個(gè)出口統(tǒng)一減壓后運(yùn)送氣體至使用點(diǎn)。因?yàn)闅馄块g是相對(duì)**的，整個(gè)氣路系統(tǒng)壓力較大的地方也是氣瓶出口處，因此這種方式將氣瓶壓力可能發(fā)生的危險(xiǎn)縮小至氣瓶間內(nèi)，可對(duì)人體及儀器的傷害降低。寧波實(shí)驗(yàn)室氣路安裝制造商</p></p><br
