壓力儀表常犯的兩個(gè)毛病

(1)使用過(guò)程中壓力波動(dòng)大:這種情況先要與工藝人員結(jié)合,一般是由操作不當(dāng)造成的。其中加入調(diào)節(jié)的參數(shù)主要需要檢查調(diào)節(jié)系統(tǒng)。

( 2 )使用過(guò)成中壓力突然變小、變大或指示曲線(xiàn)無(wú)變化:這個(gè)時(shí)候應(yīng)該檢查變送器的引壓系統(tǒng),檢查根部閥是否堵塞、引壓管是否暢通、引壓管內(nèi)部是否有異常介質(zhì)、排污絲堵及排污閥是否泄漏等。冬季介質(zhì)凍也是常見(jiàn)現(xiàn)象。變送器本身故障可能性很小。
