", "La pompe centrifugeue à haute vitesse rencontre un problème : pendant le fonctionnement avec un flux deu constant质量流量运行),发现电流慢慢上涨,泵出口出口压力慢慢降低,电流高到跳车,求急援,大神们分析下啊

"高速泵,假如机械上出现问题,振动和声音会反映出异常 " "如果 若仅仅是电流上升,介质物性变化的可能性比较大,特别是密度和粘度增加较多时也会有影响 " "L'expression "在恒定的质量流量运行" 比较合理的是"恒定的体积流量运行),当恒定体积流量运行密度上升后,质量流量增加,电流增加敏感 " " "是质量流量不变,密度降低,体积流量增大,扬程减小,不知道这么理解对不对 " " "是质量流量不变。如果密度降低 体积流量增大 � � �扬程减小 不不知道对不对 " " "从泵的曲线角度分析 � � �流量增大 扬程下降 也有道理。 �密度变化很大以至于影响到流量明显增大 压力下降? " " "所谓的恒"的质量流量,都是先设定好介质密度根据体积流量算出来的 �很大可能是密度变化引起的 " " "超流量了 � 压力一般要低一点。 " " "要看介质 �看温度 "看压力差 "看扬程 ""]

看介质,看温度,看压力差,看扬程
