上量不稳定:叶轮口环间隙过大、(更换口环)叶轮流道堵塞、(清理流道杂质)泵抽空、(检查液位、重新灌泵排气)吸入管线堵塞或漏气、(检查吸入管线)介质温度过高气化(降温冷却后重新排气灌泵)。

泵体振动过大:泵发生气蚀抽空(排除)轴承老化(更换)联轴器对中不良(重新校正)地脚螺栓或各连接螺栓有松动(检查拧紧)

Pump body vibration too large: pump cavitation and evacuation (removal) bearing aging (replacement) shaft coupling for bad (rectified) anchor bolts or joint bolts loosening (check tightening)
