1, 我厂一台低温-33度输液泵,建筑物实际高度

1、泵的扬程一般是以水进行标定的,不知道你的这个低温液体的密度是多少,可以进行扬程换算。 2、离心泵的流量和电流不能成正比,离心泵有自己的流量特性曲线,这个你可以在网上查查。 3、温度高有可能是泵的循环冷却不良,注意把温度高的泵的认真检查循环冷却,不要把轴承烧了。

温度高应该是进的多出的少,介质被重复做功引起的!

重复做功的确会引起温度升高,但泵出口阀开度大小我是按额定电流调节的,即泵出口阀逐渐开大到额定电流为止。能否说明流量也达到额定了呢

并不是你按照正常操作就没有问题了!要是选型问题呢!既然扬程用不了这么多可以去切割叶轮(保留前后盖板只车割流道叶片!若车刀无法车的这么深可以去一部分后盖板)!也可以在叶轮入口口环内侧加个口环减少进液量!微信18615002545有问题随时交流!
