產品詳情
為什么要除霜?結霜主要會導致以下問題:總結一點就是:結霜會導致蒸發(fā)器換熱不好,直接降低了冷機的冷量。結霜前:結霜后:多久需要做一次除霜,每次除霜多長時間?1)、這要考慮所儲藏產品的種類和濕度、人員在冷藏室內走動的頻度、每天開門的次數、透風情況、空氣濕度等因素。、必須盡可能頻繁地除霜,而且要盡早,以免為時太遲。、如除霜時間太短,未能將冰全部融化,則會產生更多的冰。除霜的幾種方式:目前主流除霜的幾種方式:自然除霜熱空氣、水沖霜;電加熱除霜熱氣旁通除霜自然除霜機理與過程:包括空氣除霜與水沖霜空氣除霜:利用蒸發(fā)器的熱空氣(高于4℃),開啟蒸發(fā)器風機使熱空氣循環(huán),將蒸發(fā)器的霜除掉;除霜過程:開始除霜壓縮機停機蒸發(fā)側風機繼續(xù)運轉熱空氣流過蒸發(fā)器化霜除霜完畢壓縮機啟動水沖霜:蒸發(fā)器頂部位置增加集水槽,槽底開圓孔;自來水進入集水槽之后銅管圓孔,均勻由上至下流通蒸發(fā)器翅片,一方面通過水的重力將霜沖洗干凈,一方面水的溫度比較高,將霜化成水一起流走。

PS版即預涂感光版(PresensitizedOffsetPlates)的簡稱,是為適應平版印刷的迅速發(fā)展而研制開發(fā)出來的。由于PS版本身具有分辨力高,網點再現飽滿,層次豐富,水墨平衡易掌握,耐印力高等特點,在印刷行業(yè)得到了迅速普及。從目前掌握的統計資料來看,PS版依然是當前消耗量大,也是重要的平印版材,PS版制造業(yè)已經成為當前印刷器材制造業(yè)極其重要的支柱產業(yè)之一。PS版生產過程中要使用鹽酸、硫酸、氫氧化鈉、氟化鈉、碳酸二氫鈉等化工原料,并且需要冷卻與加熱,而這些原料大部分是強腐蝕性介質,設備必然腐蝕嚴重,必須要求諸多生產設備的材料既要能防腐蝕,又要有良好的傳熱性能。
