描述

壓力表的安裝（1）壓力表應(yīng)安裝在易觀察和檢修的地方。（2）安裝地點(diǎn)應(yīng)力求避免振動(dòng)和高溫影響。（3）測量蒸汽壓力時(shí)應(yīng)加裝凝液管，以防止高溫蒸汽直接和測壓元件接觸；對(duì)于有腐蝕介質(zhì)時(shí)，應(yīng)加裝充有中性介質(zhì)的隔離罐等。總之，針對(duì)具體情況（如高溫、低溫、腐蝕、結(jié)晶、沉淀、粘稠介質(zhì)等），采取相應(yīng)的防護(hù)措施。壓力表的連接處應(yīng)加裝密封墊片，一般低于80℃及2MPa壓力用石棉紙板或鋁片，溫度及壓力更高時(shí)（50MPa）用退火紫銅或鉛墊。另外還要考慮介質(zhì)的影響，例如測氧氣的壓力表不能用帶油或有機(jī)化合物的墊片，否則會(huì)引起爆炸。測量乙炔壓力時(shí)禁止用銅墊。
