style="text-indent:25px">目前，實(shí)驗(yàn)室購置的許多大型儀器設(shè)備必須依賴某種工作氣體才能正常工作，有些氣體用于儀器設(shè)備驅(qū)動(dòng)控制，如壓縮空氣，由于氣體供應(yīng)不符合要求，經(jīng)常會(huì)引起儀器工作狀態(tài)異常，甚至造成儀器設(shè)備的損壞。完善的氣體管道配送系統(tǒng)也是一個(gè)優(yōu)良實(shí)驗(yàn)室的重要指標(biāo)，那么實(shí)驗(yàn)室氣路安裝的標(biāo)準(zhǔn)和注意事項(xiàng)有哪些呢？實(shí)驗(yàn)室氣體管道安裝標(biāo)準(zhǔn)：氫氣、氧氣、煤氣管道以及引入實(shí)驗(yàn)室的各種氣體管道支管宜明敷。當(dāng)管道井、管道技術(shù)層內(nèi)敷有氫氣、氧氣和煤氣管道時(shí)，應(yīng)有換氣的次數(shù)為每小時(shí)1～3次的通風(fēng)措施。</p><p
