style="text-indent:25px">檢查氣體管道，A級試漏：對氣路嚴(yán)重泄漏的較粗略觀察。通常在氣源打開并穩(wěn)定之后，不應(yīng)聽到氣路流經(jīng)的各管路及閥件接頭處有絲絲的跑氣聲，如聽到明顯的漏氣聲，說明系統(tǒng)有大漏!必須依據(jù)漏氣聲，追查出泄漏處，并加以排除。引起系統(tǒng)大漏的常見原因是：氣路接頭沒上緊，氣路中管路開裂及沒加合適的墊片等。查找氣路的嚴(yán)重泄漏，也可在流路的流量開到較大時，用肥皂水在各接頭逐步測試有無氣泡出現(xiàn)而加以證實。 B級試漏：對氣路中輕微漏氣的檢查。方法是堵住氣路出口，觀察氣路中流量計內(nèi)的轉(zhuǎn)子。如果能緩緩下降為零，即可認(rèn)為此氣路B級試漏合格。如轉(zhuǎn)子不能降到零，可用肥皂水在各接頭處仔細觀察。直到找到泄漏處為止。</p><p
