十、進口單級臥式離心泵起動與停車

進口單級臥式離心泵起動前準備

1、試驗電機轉向是否正確,從電機頂部往泵看為順時針旋轉,試驗時間要短,以免使機械密封干磨損。

2、打幵排氣口使液體充滿整個泵體,待滿后關閉排氣閥。

3、檢查各部位是否正常。

4、用手盤動泵以使?jié)櫥哼J入機械密封端面。

5、高溫型應先逬行預熱,升溫速度50℃/小時,以保證各部受熱均勻。

十一、進口單級臥式離心泵起動前檢查

1、全開進口處閥門。2、關閉吐出管路閥門。3、起動電機,觀察泵運行是否正桷。4、調節(jié)出口閥幵度以所需工況,如用戶在泵出口處裝有流靈表或壓力表,應通過調節(jié)出口閥門幵度使泵在性能參數(shù)表所列的頷定點上運轉,如用戶在泵出口處裝有流量表或壓力表,應通過調節(jié)出口闔門幵度,測量泵的電機電流,使電機在額定電流內運行,否則將造成泵超負荷運行(即大電流運行)至使電機燒壞。調正好的出口閥門幵啟大與小和管道工況有關。5、檢査軸封泄漏情況,正常時機械密封泄漏應小于3滴/分。6、檢查電機、軸承處溫升≦70℃。

停車

1、高溫型先降溫,降溫速度<10℃/分,把溫度降低到80℃以下,才能停車。2、關閉吐出管路閥門。3、停止電機。4、關閉進口處閥門。5、如長期停車,應將泵內液體放盡。

七、進口單級臥式離心泵泵的維護

1、運行中的維護

(2)進口處管道必須充滿液體,禁止泵在汽蝕狀態(tài)下長期運行。(2)定時檢查電機電流値,不得超過電機頷定電流。(3)泵進行長期運行后,由于機械磨損,使機組噪音及振動增大時,應停車檢查,必要時可更換易損零件及軸承,機組大修期一般為一年。

2、機械密封維護

(1)機械密封潤滑應清潔無固體顆粒。(2)嚴禁機械密封在干磨情況下工作。(3)起動前應先盤動泵(電機)幾圈,以免突然起動造成石墨環(huán)斷裂損壞。(4)密封泄漏量允差3滴/分。否則應檢查。

十二、進口單級臥式離心泵故障現(xiàn)象

故障現(xiàn)象故障原因排除方法
