注意事項:

ISWRG型臥式管道熱水高溫循環(huán)離心泵安裝說(shuō)明

1、安裝前應檢查水泵和電機有無(wú)損傷,泵流道內有無(wú)影響水泵運行的硬質(zhì)物體(如石塊、鐵粒等),以免水泵運行時(shí)損壞葉輪和泵體。    

2、安裝時(shí)管路重量不應加在水泵上,應有各自的支承體,以免泵變形影響運行性能和壽命。

3、泵與電機是整體結構,安裝時(shí)無(wú)需找正,十分方便。

4、當輸送熱水液體時(shí),為了不使泵承受管路的熱變形,泵座的底腳螺栓可以不固定,當管路系統在熱脹冷縮時(shí),使泵能與管路一起移動(dòng)。

5、泵體兩端法蘭規格均按1.6 M Pa標準確定,所以配備管路時(shí)應規格相同。

6、為了不使雜質(zhì)進(jìn)入泵內而堵塞流道影響性能,應在泵進(jìn)口前面安裝比吸入管截面積大3-4倍的過(guò)濾器。

7、排出管路如裝逆止閥應裝在閘閥的外面。

8、泵用于有吸程場(chǎng)合,應裝有底閥,并且進(jìn)出口管路不應有過(guò)多彎道,同時(shí)不得有漏水、漏氣現象。

9、為了維修方便和使用安全,在泵的進(jìn)、出口管路上各安裝一只調節閥及在泵出口附近安裝一只壓力表,以保證泵在額定范圍內運行,確保泵的正常運行和使用壽命。

10、安裝完畢后盤(pán)動(dòng)泵軸,葉輪應無(wú)摩擦和卡死現象。


ISWRG型臥式管道熱水高溫循環(huán)離心泵使用說(shuō)明

啟動(dòng)、運行、停機

(一)起動(dòng)、運轉:

1、用手撥轉電機風(fēng)葉,葉輪應無(wú)卡磨現象,轉動(dòng)靈活。

2、用手盤(pán)動(dòng)泵以使潤滑液進(jìn)入機械密封端面。

3、灌水排氣,打開(kāi)進(jìn)口閥,使液體充分進(jìn)入泵腔內,直至整個(gè)管路充滿(mǎn)液體,并保證進(jìn)口管路的密封性。

4、關(guān)閉出口閥,以減少起動(dòng)電流。 .

5、接通電源,點(diǎn)起動(dòng)確定正確運行方向,從電機風(fēng)葉端看為順時(shí)針旋轉。

6、逐步調節出口閥的開(kāi)度,盡量使泵在額定狀態(tài)下工作。

7、泵在運轉過(guò)程中,如發(fā)現噪音或不尋常的聲音時(shí),應立即停機檢查。

8、正常機械密封泄漏應小于3滴/分,檢查電機,軸承處溫升<70 ℃,超過(guò)此值應檢查原因。

(二)停機:

1、關(guān)閉吐出管路閥門(mén)。

2、切斷電源,停止電機運行。

3、關(guān)閉進(jìn)口閥。

4、泵長(cháng)期停用,應放盡泵內液體。


ISWRG型臥式管道熱水高溫循環(huán)離心泵維護與保養

(一)運行中的維護和保養:

1、進(jìn)水管路必須高度密封。

2、禁止泵在汽蝕狀態(tài)下長(cháng)期運行。.

3、禁止泵在大流量運行時(shí),電機超電流長(cháng)期運行。

4、定時(shí)檢查泵運行中電機電流值,盡量使泵能在標準下工作。

5、泵在運行過(guò)程中應有專(zhuān)人看管,以免發(fā)生意外。

6、泵每運行500小時(shí)應對軸承進(jìn)行加油。電機功率大于11kW配有加油裝置,可用高壓油槍直接注入,以保證軸承潤滑優(yōu)良。

7、泵進(jìn)行長(cháng)期運行后,由于機械磨損,使機組噪聲及振動(dòng)增大時(shí),應停機檢查,必要時(shí)可更換易損零件及軸承,機組大修期一般為一年。


(二)機械密封維護與保養:

1、機械密封潤滑應清潔無(wú)固體顆粒。

2、嚴禁機械密封在干磨情況下工作。

3、起動(dòng)前應盤(pán)動(dòng)泵(電機)幾圈,以免突然起動(dòng)造成密封環(huán)斷裂損壞。
