16問：供水溫度與回水溫度的溫差超過額定值，怎么回事?供水溫度與回水溫度的溫差越小，說明系統(tǒng)的流量越大，系統(tǒng)越暢通。反之，如果供水溫度與回水溫度的溫差越大(超過額定值)，說明系統(tǒng)的流量小，系統(tǒng)循環(huán)不夠暢通。此時檢查過濾器和換熱器以及管道相應的閥門是否堵塞。供熱機組**名詞解釋1.一次側：指熱源，例如鍋爐房的熱水或者蒸汽。2.二次側：指熱用戶，例如地暖，散熱器，中央空調等等熱用戶。3.供水：無論是一次側或二次側，熱水為供水，即溫度高的管路為供水。4.回水：無論是一次側或二次側，冷水為回水，即溫度低的管路為回水。5.高溫水：溫度高于等于100度的水，國家規(guī)范為130/80度，即供水溫度為130度，回水溫度為80度。6.低溫水：溫度低于100度的水，國家規(guī)范為95/70度，吉林節(jié)能機組的用途和特點，即供水溫度為95度，回水溫度為70度。說明：高溫水、低溫水都是針對于一次側系統(tǒng)定義的。機組正常運行參數(shù)顯示規(guī)律1.供水溫度高于回水溫度，供水壓力高于回水壓力。2.一次側供水壓力與回水壓力的差值應大于等于。3.板式換熱器二次側進口與出口壓力的差值應小于等于。4，吉林節(jié)能機組的用途和特點.一次側如果為高溫水，供水溫度與回水溫度的溫差不能高于40度，吉林節(jié)能機組的用途和特點。5.一次側如果為低溫水。</p><div

板式換熱器的主要技術改進特點：（一）換熱器的傳熱板片：采用不銹鋼板材或鈦板，在2萬噸板式換熱器**油壓機上一次壓制成形，避免了重復沖壓,板片沖壓時采用雙面涂油覆膜技術，保證板片成型精度高，板片減薄量控制在,模具為組合式合模即整個模具由若干塊小模具拼裝而成即保證板片沖壓成型應力均勻同時當其中某塊模具出現(xiàn)磨損時可迅速更換,保證模具的精度,板片設計采用超細網(wǎng)格的數(shù)值模擬技術結合精密的實驗測量方法，設計出流動和傳熱性能優(yōu)越的換熱板片；板片在低流速下能夠產(chǎn)生高湍流及高換熱系數(shù)；板片在一定的換熱系數(shù)下具有更小的阻力系數(shù)；“人”字形波紋板片在板片之間形成多達數(shù)千個接觸點，壓制的板片具有極高的精度，它使得板片之間的接觸點承壓均勻，從而能承受高達25bar以上的壓力。

板片進口分流區(qū)采用網(wǎng)格狀設計板片的進口分流區(qū)設計有流線引導槽，它具有拉近不同流道上的流動阻力之差別的作用，使得流體在板片換熱區(qū)域均勻分布，從而避免了不均勻流量分配和流動死角所帶來的換熱效率下降，點蝕和結垢等弊端。對于寬度較大的板片，還增加了順等勢線均壓槽，從而形成了流線引導槽和順等勢線均壓槽交叉形成的阻力很小，具有近乎完美的均流作用的網(wǎng)格狀進口分流區(qū)。同時分流區(qū)還起到快速形成紊流強烈換熱的作用，使分流區(qū)提前參與換熱，有效的提高了換熱長度，減少換熱面積。（普通板片分流設計的弊?。涸谕橇鲿r冷介質若從左側進出板片，在短路效果作用下冷介質在板片左側易形成紊流換熱區(qū)，右側則易形成流動死區(qū)；而熱介質從右側進出板片，在短路效果作用下熱介質在板片右側易形成紊流***換熱區(qū)，左側則易形成流動死區(qū)；使換熱效果惡化）。
