深井泵安全操作规程
1.深井泵应使用于含砂量低于0.01%的清水源，泵房内设0.2m3左右的预润水箱，储存满足一次起动的预润水量。
2.水泵在运转前，应将清水灌入泵内，预润水泵轴和橡胶轴承，使摩擦阻力减少，更于起动。
3.泵不能在无液体的情况下空转；水泵一、二级叶轮应浸入水位以下。
4.运转中，如发现基础周围有较大振动时，应检查水泵的橡胶轴承或电机填料处磨损情况，如磨损过多、漏水，应更换新件。
5.停泵前，应先关闭出水阀，切断电源，锁好电闸箱。停车后出水管中的水尚未全部流回深井时，不得开动水泵，以免水泵轴功率突增引起故障，应间隔10—15min再开机。水泵停转后还应及时检查防倒装置是否灵活有效。
6.冬季水泵长期停用时，应放出其中的积水，以免冻坏泵体。
