                氟塑料自吸泵遇到高溫時如何處理
                來源:www.yvettesblogs.com 發布時間:2014-09-30 15:57
                  通常情況下,氟塑料自吸泵的溫度在104-120℃左右。然而,也有一些項目情況比較特殊,溫度會達到160以上。在這種情況時,給水泵往往會因為水泵溫度過高,導致軸承升溫超標,由于汽化產生氣蝕,葉輪、密封環、導葉套等部件過早磨損。各結合部零部件變形,平衡系統失效,導致整個設備癱瘓。遇到這種情況,建議采用以下措施:
                  1.改變材質。球墨鑄鐵材質,散熱快,不易變形,但鑄造、機加工難度大,工藝要求高;鑄鋼材質散熱慢,部件容易變形;兩種材質各有所長,用來制作泵殼效果好一些;轉子部件采用比較耐磨的2Cr13材質比較好。平衡盤經過特殊處理(高頻淬火),平衡環最好采用2Cr13材質配合;
                  2,選用進口軸承;
                  3.選用耐高溫機械密封;
                  4.改變冷卻配置,最直接有效的方法是加裝冷卻器。
