十、进口单级卧式离心泵起动与停车

进口单级卧式离心泵起动前准备

1、试验电机转向是否正确,从电机顶部往泵看为顺时针旋转,试验时间要短,以免使机械密封干磨损。

2、打幵排气口使液体充满整个泵体,待满后关闭排气阀。

3、检查各部位是否正常。

4、用手盘动泵以使润滑液逬入机械密封端面。

5、高溫型应先逬行预热,升溫速度50℃/小时,以保证各部受热均匀。

十一、进口单级卧式离心泵起动前检查

1、全开进口处阀门。2、关闭吐出管路阀门。3、起动电机,观察泵运行是否正桷。4、调节出口阀幵度以所需工况,如用戶在泵出口处裝有流靈表或压力表,应通过调节出口阀门幵度使泵在性能参数表所列的颔定点上运转,如用戶在泵出口处装有流量表或压力表,应通过调节出口阖门幵度,测量泵的电机电流,使电机在额定电流內运行,否则将造成泵超负荷运行(即大电流运行)至使电机烧坏。调正好的出口阀门幵启大与小和管道工况有关。5、检査轴封泄漏情况,正常时机械密封泄漏应小于3滴/分。6、检查电机、轴承处溫升≦70℃。

停车

1、高溫型先降溫,降溫速度〈10℃/分,把溫度降低到80℃以下,才能停车。2、关闭吐出管路阀门。3、停止电机。4、关闭进口处阀门。5、如长期停车,应将泵內液体放尽。

七、进口单级卧式离心泵泵的维护

1、运行中的维护

(2)进口处管道必须充满液体,禁止泵在汽蚀状态下长期运行。(2)定时检查电机电流値,不得超过电机颔定电流。(3)泵进行长期运行后,由于机械磨损,使机组噪音及振动增大时,应停车检查,必要时可更換易损零件及轴承,机组大修期一般为一年。

2、机械密封维护

(1)机械密封润滑应清洁无固体颗粒。(2)严禁机械密封在干磨情况下工作。(3)起动前应先盘动泵(电机)几圈,以免突然起动造成石墨环断裂损坏。(4)密封泄漏量允差3滴/分。否则应检查。
