前壓力值，并把該值作為智能電子壓力開關(guān)設(shè)定值，從而實現(xiàn)壓力開關(guān)的智能校驗。流程選擇開關(guān)，旁接罐流程、密閉流程可設(shè)置不同的門檻值，旁接罐流程設(shè)置的門檻值可適當(dāng)降低，從而克服了旁接罐流程壓力開關(guān)不能投用的難題。目前，國內(nèi)針對原油的運送方式主要采用管道加熱輸送工藝。原油在管道輸送中每間隔40～90 km就設(shè)一個分站來進(jìn)行加熱、加壓。為降低能源消耗我國輸油管道都進(jìn) 行了現(xiàn)代化技術(shù)改造實現(xiàn)了計算機監(jiān)控。在輸油管道監(jiān)控系統(tǒng)中為保護(hù)管線防止出站壓力超高造成爆管，在出站及泵出口匯管處安裝了壓力開關(guān)。為防止輸油泵抽空在進(jìn)站管線及泵入口管線上也安裝了壓力開關(guān)。電子壓力開關(guān)可以進(jìn)行更精細(xì)的切換。</p><div

通過適當(dāng)?shù)膬x表，在普通大氣壓和標(biāo)準(zhǔn)溫度條件下，核實壓力傳感器的頻率反應(yīng)值。(2) 核實壓力傳感器的編碼與相應(yīng)的頻率反應(yīng)信號的正確性。2. 確定具體安裝位置，為了確定壓力傳感器的編號和具體安裝位置，需按充氣網(wǎng)的各個充氣段來考慮：(1) 壓力傳感器必須沿著線纜進(jìn)行安裝，較好安裝在線纜接頭處。(2) 每條線纜裝設(shè)壓力傳感器不少于4個，靠近電話局的兩個壓力傳感器，相距不應(yīng)大干200m。(3) 每條線纜的始端和末端分別安裝1個。(4) 每條線纜的分支點應(yīng)裝1個，如果兩個分支點相距較近(小于100 m)，可只裝1個。(5) 線纜敷設(shè)方式(架空、地下)改變處應(yīng)裝1個。(6) 對無分支的線纜，因壘線的線纜程式一致，壓力傳感器的安裝隔距不大干500m，并使其總數(shù)不少于4個。(7) 為了便于確定壓力傳感器故障點，除在起點安裝壓力傳感器外，距起點150~200m處，還要另外安裝1個當(dāng)然在設(shè)計中，一定要考慮經(jīng)濟(jì)與技術(shù)的因素，在不需要安裝壓力傳感器的地方，則應(yīng)不必安裝。如果安裝孔的尺寸不合適，電子壓力傳感器在安裝過程中，其螺紋部分就很容易受到磨損。小型電子流量開關(guān)維修</p><p
