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。減溫減壓裝置控制精度高，運(yùn)行平穩(wěn)，調(diào)節(jié)靈敏，可有效去除靜差影響。虹口區(qū)減溫減壓裝置品牌哪家好</p><p
