    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基本符合標準ISO2858及國家標準JB/T6878.2-93的規定。具有設計規范，通用化程度高，結構合理，性能穩定，運轉低噪音，無振動等顯著特點，是替代常規臥式離心泵，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。

     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，噪音低。

   4、取消傳統軸封方式，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電機滾動軸承，使泵具有運行特別平穩，振動噪音極低。

   6、安裝栓修方便，無需拆動管路系統，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、可根據使用要求即流量和揚程的需要進行泵的串、并聯運行方式。

    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。

六、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。

七、SPG型管道式屏蔽泵-維護與保養

  一、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。

  二 、運行中的維護保養

   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象。

   2、定時記錄電泵的負載電流和不平衡度。電泵發生故障時大多數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定的輸液溫度，避免電泵*處于超溫狀態下運行，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值，進口處壓力表的數值不得小于零，出口處的壓力表數與進口處壓力表數的差值，必須符合銘牌上的規定的壓力值。

   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。因此發現異常因立即停電檢查。

   7、定時檢查電泵循環液通路，過濾裝置是否有阻塞現象。

   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、定期檢查葉輪口環與泵體的配合間隙，因此間隙會直接影響電泵的性能，在一般情況下，間隙超過1.5mm，則應更換新的葉輪，在特殊情況下也可采用修補工藝來改善。

八、SPG型管道式屏蔽泵-起動、運轉和停車

  一、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，如發現有異常，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。

  二、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。

九、SPG型管道式屏蔽泵-故障原因及排除方法故障現象可能產生的原因排除方法

   1、水泵不出水1、進出口閥門未打開，進出管路阻塞葉輪流道阻塞。

   2、電機運行方向不對，電機缺相轉速很慢。

   3、吸入管漏氣。

   4、泵腔內存有空氣。

   5、進口供水不足。

   6、管路阻力過大，泵選型不當。

   1、檢查，去除阻塞物

   2、調整電機轉向，緊固電機接線

   3、擰緊各密封面，排除空氣
