                化工泵介質粘度有什么要求
                來源:www.yvettesblogs.com 發布時間:2018-10-31 14:54

                  化工泵包括泵體、軸,進水接管與吸入蓋通過螺栓聯接并通過止口、螺釘固定在泵體的左側;軸套、軸套墊、葉輪通過葉輪螺母固定在軸上,機械密封安裝在軸套上,軸通過軸承安裝在軸承架內,軸承架的左側設有泵蓋。該化工泵的結構簡單、維修方便。

                  介質的粘度對泵的性能影響是很大的,當粘度增加時,泵的揚程曲線下降,最佳工況的揚程和流量均隨之下降,而功率則隨之上升,因而效率降低。一般樣本上的參數均為輸送清水時的性能,當輸送粘性介質時應進行換算。對于粘度較高的漿類、膏類及粘稠液的輸送,建議選用螺桿泵,G單螺桿泵適用介質粘度可達1000000cst。
