四、SPG屏蔽式管道離心泵詳細資料：

    SPG型管道式屏蔽泵-型號意義 SPG型管道式屏蔽泵-產品簡介 SPG管道式屏蔽泵，并吸收了上屏蔽泵設計及制造的*技術，漿電機的屏蔽技術應用于液體輸送領域，為適應國內市場需求而推出的系列化新產品。 SPG型管道式屏蔽泵系列性能參數(shù)基本符合標準ISO2858及國家標準JB/T6878.2-93的規(guī)定。具有設計規(guī)范，通用化程度高，結構合理，性能穩(wěn)定，運轉低噪音，無振動等顯著特點，是替代常規(guī)臥式離心泵，立式管道泵的理想產品。 全系列共67個品種，184個規(guī)格，其性能范圍：流量6.3~108m3/h，揚程12.5~125m,配用電機功率0.37~160KW,轉速1450r/min和2900r/min。

五、SPG型管道式屏蔽泵-產品特點

   1、泵結構緊湊，機泵一體化，體積小。其立式結構具有安裝占地面積小，運行平衡，安裝無需調整。

   2、泵進出口設計成規(guī)格相同法蘭，且位于同一中心線上，可象閥門一樣直接安裝在管路上，且中心低便于管道布置，安裝特別方便。

   3、泵與電機同軸，軸向尺寸短，使泵運行更加平穩(wěn)，噪音低。

   4、取消傳統(tǒng)軸封方式，避免了輸送介質的外泄，因此具有*無泄漏的顯著特點。

   5、用滑動軸承替代常規(guī)電機滾動軸承，使泵具有運行特別平穩(wěn)，振動噪音極低。

   6、安裝栓修方便，無需拆動管路系統(tǒng)，只要拆下連接體螺母即可抽出全部轉子部件進行檢查和維修。

   7、可根據(jù)使用要求即流量和揚程的需要進行泵的串、并聯(lián)運行方式。

六、SPG型管道式屏蔽泵-結構說明

   該泵為機泵一體結構，整機主要由泵體、葉輪、聯(lián)接體、滑動軸承、定子、轉子、屏蔽套、電機殼等零部件組成。泵為立式單級單吸離心式，進出口在同一水平軸線上，口徑規(guī)格相同可直接象閥門一樣安裝在管路的任何部位上，裝卸極為方便，占地面積省。泵通過聯(lián)接體與電機成一體，軸承采用進口石墨浸漬樹脂復合軸承，電機定轉子各有屏蔽套進行隔離。軸承采用液體本身介質作為潤滑劑及冷卻液，具有設計合理、運行可靠的特點。泵設有底座，可直接安裝在地基上，因該泵具有低噪音，無振動特點，安裝時無需加裝隔振器與隔振墊。1泵 體10定子屏蔽套2密 封 環(huán)11上軸承座3葉 輪12轉子端蓋4下軸承座13定子屏蔽套5電機接線盒14軸 承6電機殼體15泵 蓋7軸 承16冷卻水管部件8定子總成17軸9轉子總成 SPG型管道式屏蔽泵-材質序號零件名稱冷熱水腐蝕性流體1泵體HT200，ZG251Cr18Ni92上軸承座3Cr131Cr18Ni93葉輪HT200,ZG251Cr18Ni94下軸承座3Cr131Cr18Ni95電機殼體HT200,ZG251Cr18Ni9i6屏蔽套0Cr17Ni4Mo20Cr19Nil17軸承石墨浸漬樹脂石墨浸漬樹脂8軸套45，0Cr17Ni4Mo21Cr18Ni9Ti9其它接液部HT200,0Cr17Ni4Mo21Cr18Ni9Ti10非接液部HT200,20HT200,20

八、SPG型管道式屏蔽泵-安裝說明

   1、安裝前應檢查機組緊固件有無松動現(xiàn)象，泵體流產內有無異物堵塞，以免水泵運行時損壞葉輪和泵體。

   2 、安裝時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使用壽命。

   3 、為了不使雜質進入泵內而堵塞流道影響性能，應在泵進口前面安裝比吸入管截面積大3~4倍的過濾器。

   4 、如泵用于輸送熱水液體時，為了不使泵承受管路的熱變形，泵可以不固定底腳螺栓，當管路系統(tǒng)在熱脹冷縮時，使泵與管路同時移動。

   5 、為了維修方便和使用安全，在泵的進出口管路應各裝上一只調節(jié)閥門及在泵進出口附近各安裝一只壓力表，以保證在額定范圍內運行，確保泵的正常運行和使用壽命。

九、SPG型管道式屏蔽泵-維護與保養(yǎng)

      起動前的準備及檢查：

   1、 檢查屏蔽電機和起動設備的接地裝置是否良好和完整，接線是否正確，接觸是否可靠。

   2、 對新安裝和*停用的屏蔽電機，使用前應檢查電機定子繞組對地的絕緣電阻。

   3、管路中必須充滿輸送液體，否則將影響電機的使用壽命。

      運行中的維護保養(yǎng)

   1、 定時記錄電源電壓的變化和電壓的不平衡度。電源電壓過高或過低，三相電壓的不平衡造成電流的不平衡，都可能引起電機的過熱或其它不正常現(xiàn)象。

   2、定時記錄電泵的負載電流和不平衡度。電泵發(fā)生故障時大多數(shù)會反映到定子繞組的電流的劇增，使電機過熱。

   3、定時記錄管路中的輸液溫度，以確保實際的輸液溫度低于或等于銘牌上所規(guī)定的輸液溫度，避免電泵*處于超溫狀態(tài)下運行，而降低電機的使用壽命。

   4、 定時記錄電泵進、出口端上的壓力表數(shù)值，進口處壓力表的數(shù)值不得小于零，出口處的壓力表數(shù)與進口處壓力表數(shù)的差值，必須符合銘牌上的規(guī)定的壓力值。

   5、電泵在每一次使用前要排氣一次，在*運行時，必須每星期排一次氣。因泵經長時間運行，水分子在電泵內被高速攪拌和撞擊，同時被輸送的介質帶有一定的溫度故液體漿產生

   6、注意電泵的氣味，振動和噪聲，電機的繞組因溫度過高就會發(fā)出絕緣的焦味。一般的機械故障會反映為振動和噪聲。因此發(fā)現(xiàn)異常因立即停電檢查。

   7、定時檢查電泵循環(huán)液通路，過濾裝置是否有阻塞現(xiàn)象。

   8、定期維修測量石墨軸承和軸套之間的間隙，以確保定子屏蔽套與轉子屏蔽套之間間隙均勻，運轉可靠。一般情況以下表為限，如超過表中的規(guī)定就應修復或更換。軸套外徑（mm）磨損極限間隙（mm）標準zui大間隙（mm）>18~300.400.131>30~500.450.158>50~800.500.192 9、定期檢查葉輪口環(huán)與泵體的配合間隙，因此間隙會直接影響電泵的

十、SPG型管道式屏蔽泵-起動、運轉和停車

     起動、動轉：

   1、灌水排氣、打開進口閥，使液體充分進入泵腔內，打開電機頂部排氣閥，待滿后關閉排氣閥。

   2、關閉出口閥，以減小起動電流。

   3、檢查各部位是否正常。

   4、接通電源，起點動確定正確運行方向。

   5、逐步調節(jié)出口閥的開度，盡量使泵在額定性能范圍內工作。

   6、泵的運轉過程中，如發(fā)現(xiàn)有異常，應立即停車檢查排除。

   7、檢查電機電流值及溫升是否符合要求。

      停車

   1、關閉吐出管路閥門。

   2、切斷電源，停止電機運行。

   3、關閉進口閥。

   4、泵如*停用，應放盡泵內的液體。

十一、SPG型管道式屏蔽泵-故障原因及排除方法故障現(xiàn)象可能產生的原因排除方法

   1、水泵不出2、進出口閥門未打開，進出管路阻塞葉輪流道阻塞。3.、電機運行方向不對，電機缺相轉速很慢。4、吸入管漏氣5、泵腔內存有空氣6、進口供水不足7、管路阻力過大，泵選型不當1、檢查，去除阻塞2、調整電機轉向，緊固電機接3、擰緊各密封面，排除空氣4、打開電機頂部排氣閥，排盡空氣。5、停機檢查、調整。6、減少管路彎道，重新選泵。2、水泵流量不足1、先按上述原因檢查。2、管道、泵流道葉輪部分阻塞，水垢沉積、閥門開度不足3、電壓偏低，轉速過低。4、葉輪口環(huán)磨損，泄漏過大。1、先按上述排除2、去除阻塞物，重新調整閥門開度。3、穩(wěn)壓4、更換葉輪3、功率過大1、超過額定流量使用。2、葉輪或運轉部件有碰擦。3、滑動軸承磨損或破裂。4、介質比重過大。 1、調節(jié)出口閥門，降低流量2、檢查排除或更換部件3、更換滑動軸承4、改型4、雜音振動1、管路支撐不穩(wěn)2、介質混有氣體3、產生汽蝕現(xiàn)象4、轉動部件碰擦 1、穩(wěn)固管路2、提高吸口壓力，排氣。3、降低真空度4、檢查調整或更換5、電機發(fā)熱1、流量過大，超載運行2、定子，轉子有碰擦。3、電壓不足4、冷卻系統(tǒng)管路堵塞1、調節(jié)出口閥，減小流量2、檢查排除3、穩(wěn)壓4、清除堵塞
