<p> <span style="font-size:18px;">2、加壓至1.8MPa,此值可由標準壓力表讀出；逆時針轉動設定值調節(jié)鏍桿，使設定值由小變大，直至微動開關在1.8MPa處切換。</span> </p> <p> <span style="font-size:18px;">3、旋動鎖緊器，調節(jié)校驗臺壓力，使其在1.8MPa處上下來回變化，校驗壓力下降時，切換值是否為1.8MPa，此值即為要求設定的下切換值，此值加上切換差（約0.85MPa)即為上切換值。</span> </p><h1> <span style="font-size:16px;">正確選用儀表類型的參考因素</span> </h1> <p> <span style="font-size:16px;color:#E53333;"><strong> 1、信號傳送距離</strong></span> </p> <p> <span style="font-size:16px;">就地顯示壓力可以選用數顯式壓力表、液柱式壓力表、浮標式壓力表等；需要遠傳壓力信號或對壓力信號進行控制時，可以選擇遠傳壓力表、控制式壓力表、報警式壓力表等。</span> </p> <p> <span style="font-size:16px;"> <strong><span style="color:#E53333;"> 2、測點個數</span></strong><span style="color:#E53333;"><strong></strong></span></span> </p> <p> <span style="font-size:16px;">需要同時測量多點壓力時可以選擇壓力巡檢儀表。</span> </p> <p> <span style="font-size:16px;"> <strong><span style="color:#E53333;"> 3、量程</span></strong><span style="color:#E53333;"><strong></strong></span></span> </p> <p> <span style="font-size:16px;"> 根據被測壓力大小選擇合適的壓力表量程。穩(wěn)定壓力，被測壓力應落在1/3~2/3量程之間；脈動壓力，**z大壓力應不超過滿量程的1/2；高壓，**z大壓力應不超過滿量程的3/5。</span> </p> <p> <span style="font-size:16px;"> <strong><span style="color:#E53333;">4、精度</span></strong></span> </p> <p> <span style="font-size:16px;"> 根據生產過程允許的**z大測量誤差選擇，兼顧經濟性、可靠性與耐用性。</span> </p> <p> <span style="font-size:16px;"> <strong><span style="color:#E53333;"> 5、外形尺寸</span></strong><span style="color:#E53333;"><strong></strong></span></span> </p> <p> <span style="font-size:16px;">數顯壓力表一般選擇表盤直徑為φ60mm、φ80mm、φ100mm；指針儀表表盤直徑一般選為φ150mm，較差照明條件下可增大到φ200~φ250mm。</span> </p> <p> <span style="font-size:16px;color:#E53333;"><strong>6、被測介質特性</strong></span> </p> <p> <span style="font-size:16px;"> 黏稠、易結晶、具有腐蝕性或含固體顆粒的被測介質應選用平膜壓力表或帶化學密封裝置的壓力表；蒸汽或高溫介質應選不銹鋼壓力表或安裝冷凝圈；測特殊化工介質要選用**壓力表，如含氨介質選氨用壓力表，含硫介質選抗硫壓力表等。</span> 壓力控制器的日常檢修。</p><div style="width:100%;text-align:

style="font-size:18px;">首先是<strong><span

style="font-size:16px;">判斷智能壓力變送器故障的方法</span> </h1> <p> <span style="font-size:16px;"> 使用在煉化裝置中的智能壓力變送器，其輸出信號的經電纜連接在DCS系統(tǒng)上，操作人員通過DCS系統(tǒng)操作站來監(jiān)控裝置現場壓力。在出現智能壓力變送器故障時，DCS操作站上會顯示測量值偏高、偏低，或出現測量回路IOP（- ）報警。在處理故障時，首先要判斷是現場儀表的故障，還是DCS系統(tǒng)的故障。如果是現場儀表故障，那么就需要針對儀表故障的實際情況進行多角度的分析，并且根據所使用儀表的特點，采取相應的處理措施進行處理；如果故障檢測結果顯示是DCS系統(tǒng)的故障，就需要系統(tǒng)維護人員配合處理。</span> 合肥氣壓壓力控制器多少錢</p></p><br /><p>文章來源地址:
