继续翻译剩下的部分。

出口流量是多少,看看是不是入口过滤器堵塞,进口量不足,还有气泵时是否排气了,泵有没有抽空振动的现象。介质是什么?

后来清理过滤器、排气后,泵的压力上来了,但电流还只有52A

排气、清过滤器后泵的压力上来了,但电流依然低,只有52A,试车阶段

本帖最后由 backcat666 于 2018-3-21 18:16 编辑 叶轮装反了吗,叶轮背帽松动了吗,电机接线接反了吗,电机故障了吗 ,泵进口堵塞了吗,正确灌泵了吗,进出口单向阀正常吗,叶轮口环间隙在标准范围内吗? 泵工作时未必达到其额定流量,因此电流未必达到其额定电流!机泵的特性曲线和管路的特性曲线共同决定了其工作点的流量,压头,效率等参数!

流量是否达到?如果流量没有达到,是否有可能入口、过滤器堵塞,好转有空气。

是不是泵的进口压力没有达到?出口压力也偏低,有些泵的出口压力和进口压力是相关的,再检查一下管路,看看有没有地方堵塞的,或者阀门没有全开的,流量上来了,电流自然会上来。
