十、進(jìn)口單級臥式離心泵起動與停車

進(jìn)口單級臥式離心泵起動前準(zhǔn)備

1、試驗(yàn)電機(jī)轉(zhuǎn)向是否正確,從電機(jī)頂部往泵看為順時(shí)針旋轉(zhuǎn),試驗(yàn)時(shí)間要短,以免使機(jī)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(guān)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(jī)械密封端面。

5、高溫型應(yīng)先逬行預(yù)熱,升溫速度50℃/小時(shí),以保證各部受熱均勻。

十一、進(jìn)口單級臥式離心泵起動前檢查

1、全開進(jìn)口處閥門。2、關(guān)閉吐出管路閥門。3、起動電機(jī),觀察泵運(yùn)行是否正桷。4、調(diào)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(yīng)通過調(diào)節(jié)出口閥門幵度使泵在性能參數(shù)表所列的頷定點(diǎn)上運(yùn)轉(zhuǎn),如用戶在泵出口處裝有流量表或壓力表,應(yīng)通過調(diào)節(jié)出口闔門幵度,測量泵的電機(jī)電流,使電機(jī)在額定電流內(nèi)運(yùn)行,否則將造成泵超負(fù)荷運(yùn)行(即大電流運(yùn)行)至使電機(jī)燒壞。調(diào)正好的出口閥門幵啟大與小和管道工況有關(guān)。5、檢査軸封泄漏情況,正常時(shí)機(jī)械密封泄漏應(yīng)小于3滴/分。6、檢查電機(jī)、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(guān)閉吐出管路閥門。3、停止電機(jī)。4、關(guān)閉進(jìn)口處閥門。5、如長期停車,應(yīng)將泵內(nèi)液體放盡。

七、進(jìn)口單級臥式離心泵泵的維護(hù)

1、運(yùn)行中的維護(hù)

(2)進(jìn)口處管道必須充滿液體,禁止泵在汽蝕狀態(tài)下長期運(yùn)行。(2)定時(shí)檢查電機(jī)電流値,不得超過電機(jī)頷定電流。(3)泵進(jìn)行長期運(yùn)行后,由于機(jī)械磨損,使機(jī)組噪音及振動增大時(shí),應(yīng)停車檢查,必要時(shí)可更換易損零件及軸承,機(jī)組大修期一般為一年。

2、機(jī)械密封維護(hù)

(1)機(jī)械密封潤滑應(yīng)清潔無固體顆粒。(2)嚴(yán)禁機(jī)械密封在干磨情況下工作。(3)起動前應(yīng)先盤動泵(電機(jī))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(yīng)檢查。
