style="text-indent:25px">減溫減壓裝置管道故障的原因是：管道之間的溫差有著很大的差距。中間支架懸掛，冷卻減壓裝置溫度超過標(biāo)準(zhǔn)，打開注水閥后管路容易開裂;中間支撐架懸掛，頭部小頭的主應(yīng)力不大(主應(yīng)力合格)，支架懸掛。管道應(yīng)力不是此位置開裂的主要原因。管道段的溫度高于下限溫度，這將導(dǎo)致管道彎曲并軸向變形。這與實際管道變形的理論分析是一致的，表明向上和向下彎曲的主要原因是管道彎曲變形和支撐吊架間隙。如何解決這些減溫減壓裝置的管道故障問題：優(yōu)化噴水裝置。簡化疏水管的添加并改善疏水條件。重新設(shè)計和計算系統(tǒng)管道以及支架和吊架選項。</p><p style="text-indent:25px">減溫減壓裝置檢查、自控:按現(xiàn)場接線圖檢查各現(xiàn)場傳感器（壓力變送器、熱電阻、流量傳感器）、執(zhí)行機構(gòu)、水泵與控制柜間接線是否正確。檢查進出口熱電阻及壓力變送器前后是否裝反，壓力變送器量程高的為進口，量程低的為出口。水泵通電前必須注滿水將全部空氣排出，以免空運轉(zhuǎn)將水泵機械密封燒壞。在確認(rèn)水泵注滿水后，給水泵通電，檢查水泵是否正轉(zhuǎn)。如反轉(zhuǎn)，關(guān)閉水泵將任意兩相電源調(diào)換即可。檢查完畢關(guān)閉水泵。檢查儀表設(shè)定是否正確，接通儀表電源，檢查所有盤上儀表的上下限是否跟現(xiàn)場傳感器量程一致，PID儀表目標(biāo)值設(shè)定是否合理，PID儀表的正反作用（壓力調(diào)節(jié)閥正裝時調(diào)節(jié)儀表應(yīng)設(shè)反作用，反裝時應(yīng)設(shè)正作用。減溫減壓裝置在組裝后要進行測試。</p><div
