VICKERS威格士雙聯變量葉片泵3525VQH35A19-1AA-22RV系列泵芯



不定時的保護主要有制冷過冷，制熱過熱，工作壓力，工作電流，壓縮機處于低電壓運行，空調電源線接觸問題，室外熱交換不良，變頻模塊過熱過流等。排查電路板內外原因熟悉電路結構，先分清控制板的內外電路，外部檢測、外部控制等，分清故障產生是內因還是外因確定是電路控制故障還是制冷系統故障判斷室內還是室外故障。。分析出和電路板相連的每根線或插頭的作用，找出用于檢測空調性能的外接線路，檢查這些線路是否存在明顯的開、短路故障。
KCG-1/.6型高溫齒輪泵的保養(yǎng)應注意的問題1.管路及結合處有無松動現象。用手轉動KCG-1/.6型高溫齒輪泵試看KCG-1/.6型高溫齒輪泵是否靈活。向軸承體內加入軸承潤滑機油，觀察油位應在油標的中心線處，潤滑油應及時更換或補充。擰下KCG-1/.6型高溫齒輪泵泵體的引水螺塞，灌注引水。關好出水管路的閘閥和出口壓力表及進口真空表。點動電機，試看電機轉向是否正確。開動電機，當KCG-1/.6型高溫齒輪泵正常運轉后，打開出口壓力表和進口真空泵視其顯示出適當壓力后，逐漸打開閘閥，同時檢查電機負荷情況。
ISWD型臥式單級低轉速離心泵的工作條件:吸入壓力1.6MPa，或泵系統高工作壓力1.6MPa，即泵吸入口壓力+泵揚程1.6MP泵靜壓試驗壓力為2.5MPa，訂貨時請注明系統工作壓力。ISWD型臥式單級低轉速離心泵系統工作壓力大于1.6MPa時應在訂貨時另行提出，以便在制造時泵的過流部分和聯接部分采用鑄鋼材料。環(huán)境溫度4℃，相對濕度95％。所輸送介質中固體顆粒體積含量不超過單位體積的.1％，粒度.2mm。
介紹了圓塊式石墨換熱器的特性及石墨原材料對石墨制化工設備的影響。結合PVC生產工藝闡述了石墨制化工設備在PVC行業(yè)的使用情況。通過傳熱計算,對圓塊式與列管式石墨換熱器的換熱效果進行了對比。[中圖分類號]TQ325.3;TQ51.5[文獻標識碼]B[文章編號]19-7937(27)2-3-3石墨換熱器廣泛應用于電石乙炔法PVC生產中與HC1氣體或鹽酸相關的工藝過程。主要設備有:氯氫處理工段用氯化氫冷卻器,混合冷凍脫水用二級石墨冷卻器,預熱器及合成氣冷卻器,鹽酸冷卻器,乙烯氧氯化法工藝精餾工段中EDC冷卻器等。
