壓力變送器工作中的注意事項

首先我們來(lai)了解下常規壓(ya)(ya)(ya)(ya)力(li)(li)變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi) 的(de)結(jie)構以(yi)及作(zuo)用。壓(ya)(ya)(ya)(ya)力(li)(li)變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)主要(yao)是由壓(ya)(ya)(ya)(ya)力(li)(li)傳感(gan)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)、測(ce)(ce)量轉換電(dian)路和過(guo)(guo)(guo)(guo)程(cheng)(cheng)(cheng)連接(jie)(jie)部(bu)件三(san)個部(bu)分(fen)組成(cheng)的(de)。它的(de)作(zuo)用是能(neng)(neng)(neng)將(jiang)(jiang)壓(ya)(ya)(ya)(ya)力(li)(li)傳感(gan)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)感(gan)受(shou)的(de)氣體(ti)、液(ye)(ye)體(ti)等(deng)(deng)(deng)物(wu)理壓(ya)(ya)(ya)(ya)力(li)(li)參(can)數轉變(bian)成(cheng)標準的(de)電(dian)信號(hao)，以(yi)供給顯示(shi)報警儀(yi)、DCS系統、記錄儀(yi)、PLC系統等(deng)(deng)(deng)進行(xing)顯示(shi)、測(ce)(ce)量、控制調(diao)節等(deng)(deng)(deng)目(mu)的(de)。在這(zhe)些(xie)工(gong)作(zuo)中(zhong)，可能(neng)(neng)(neng)會(hui)發生很多不同的(de)問(wen)題，這(zhe)個時(shi)候就(jiu)需要(yao)注(zhu)意(yi)壓(ya)(ya)(ya)(ya)力(li)(li)變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)在工(gong)作(zuo)中(zhong)的(de)保(bao)養和防護。 下面我們來(lai)分(fen)析具體(ti)的(de)壓(ya)(ya)(ya)(ya)力(li)(li)變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)在使用中(zhong)的(de)注(zhu)意(yi)事(shi)項(xiang)。 1、首先檢查壓(ya)(ya)(ya)(ya)力(li)(li)變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)周圍有無信號(hao)干(gan)(gan)擾，如果有，盡量排(pai)除(chu)，或盡可能(neng)(neng)(neng)讓傳感(gan)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)屏蔽線與金屬外殼(ke)相連，增強抗(kang)干(gan)(gan)擾能(neng)(neng)(neng)力(li)(li)。 2、要(yao)定期(qi)清(qing)洗安(an)(an)裝(zhuang)(zhuang)(zhuang)孔，保(bao)證(zheng)安(an)(an)裝(zhuang)(zhuang)(zhuang)孔的(de)清(qing)潔(jie)．防止變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)與腐(fu)蝕性(xing)或過(guo)(guo)(guo)(guo)熱(re)的(de)介(jie)質(zhi)接(jie)(jie)觸； 3、接(jie)(jie)線時(shi)，將(jiang)(jiang)電(dian)纜(lan)穿過(guo)(guo)(guo)(guo)防水接(jie)(jie)頭(tou)(附(fu)件)或繞性(xing)管(guan)(guan)并(bing)擰緊密封螺帽，以(yi)防雨水等(deng)(deng)(deng)通過(guo)(guo)(guo)(guo)電(dian)纜(lan)滲漏進變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)殼(ke)體(ti)內。 4、測(ce)(ce)量氣體(ti)壓(ya)(ya)(ya)(ya)力(li)(li)時(shi)，取(qu)壓(ya)(ya)(ya)(ya)口(kou)(kou)應(ying)(ying)開在流(liu)程(cheng)(cheng)(cheng)管(guan)(guan)道頂端，并(bing)且變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)也(ye)應(ying)(ying)安(an)(an)裝(zhuang)(zhuang)(zhuang)在流(liu)程(cheng)(cheng)(cheng)管(guan)(guan)道上部(bu)，以(yi)便(bian)積(ji)累的(de)液(ye)(ye)體(ti)容(rong)(rong)易注(zhu)入流(liu)程(cheng)(cheng)(cheng)管(guan)(guan)道中(zhong)。 5、測(ce)(ce)量液(ye)(ye)體(ti)壓(ya)(ya)(ya)(ya)力(li)(li)時(shi)，取(qu)壓(ya)(ya)(ya)(ya)口(kou)(kou)應(ying)(ying)開在流(liu)程(cheng)(cheng)(cheng)管(guan)(guan)道側面，以(yi)避(bi)免沉淀(dian)積(ji)渣。 6、壓(ya)(ya)(ya)(ya)力(li)(li)變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)上不能(neng)(neng)(neng)使用高(gao)于36V的(de)電(dian)壓(ya)(ya)(ya)(ya)，容(rong)(rong)易導(dao)(dao)致損(sun)壞。 7、冬季(ji)發生冰凍時(shi)，安(an)(an)裝(zhuang)(zhuang)(zhuang)在室(shi)外的(de)變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)必(bi)需采取(qu)防凍措施，避(bi)免引壓(ya)(ya)(ya)(ya)口(kou)(kou)內的(de)液(ye)(ye)體(ti)因結(jie)冰體(ti)積(ji)膨脹，導(dao)(dao)至傳感(gan)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)損(sun)壞。 8、測(ce)(ce)量蒸汽或其它高(gao)溫(wen)介(jie)質(zhi)時(shi)，需接(jie)(jie)加緩沖管(guan)(guan)(盤管(guan)(guan))等(deng)(deng)(deng)冷凝器(qi)(qi)(qi)(qi)(qi)(qi)(qi)，不應(ying)(ying)使變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)工(gong)作(zuo)溫(wen)度超過(guo)(guo)(guo)(guo)極限。而且緩沖管(guan)(guan)需要(yao)注(zhu)入適量水，防止過(guo)(guo)(guo)(guo)熱(re)蒸汽與變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)接(jie)(jie)觸。而且緩沖散熱(re)管(guan)(guan)不能(neng)(neng)(neng)漏氣。 測(ce)(ce)量蒸汽管(guan)(guan)道的(de)壓(ya)(ya)(ya)(ya)力(li)(li)變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)安(an)(an)裝(zhuang)(zhuang)(zhuang)示(shi)例 9.測(ce)(ce)量液(ye)(ye)體(ti)壓(ya)(ya)(ya)(ya)力(li)(li)時(shi)，變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)安(an)(an)裝(zhuang)(zhuang)(zhuang)位置(zhi)應(ying)(ying)避(bi)免液(ye)(ye)體(ti)的(de)沖擊(水錘現象)，以(yi)免傳感(gan)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)過(guo)(guo)(guo)(guo)壓(ya)(ya)(ya)(ya)損(sun)壞。 10、導(dao)(dao)壓(ya)(ya)(ya)(ya)管(guan)(guan)應(ying)(ying)安(an)(an)裝(zhuang)(zhuang)(zhuang)在溫(wen)度波動(dong)小的(de)地方； 11、防止渣滓在導(dao)(dao)管(guan)(guan)內沉積(ji)； 12、壓(ya)(ya)(ya)(ya)力(li)(li)變(bian)送(song)(song)(song)(song)(song)(song)(song)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)測(ce)(ce)量的(de)介(jie)質(zhi)不能(neng)(neng)(neng)冷凍結(jie)冰，一(yi)旦(dan)結(jie)冰，會(hui)容(rong)(rong)易損(sun)壞膜(mo)片，因為膜(mo)片一(yi)般都很薄。
