SPG管道式屏蔽泵，并吸收了上屏蔽泵設(shè)計(jì)及制造的*技術(shù)，漿電機(jī)的屏蔽技術(shù)應(yīng)用于液體輸送領(lǐng)域，為適應(yīng)國內(nèi)市場需求而推出的系列化新產(chǎn)品。 SPG型管道式屏蔽泵系列性能參數(shù)基本符合標(biāo)準(zhǔn)ISO2858及國家標(biāo)準(zhǔn)JB/T6878.2-93的規(guī)定。具有設(shè)計(jì)規(guī)范，通用化程度高，結(jié)構(gòu)合理，性能穩(wěn)定，運(yùn)轉(zhuǎn)低噪音，無振動(dòng)等顯著特點(diǎn)，是替代常規(guī)臥式離心泵，立式管道泵的理想產(chǎn)品。 全系列共67個(gè)品種，184個(gè)規(guī)格，其性能范圍：流量6.3~108m3/h，揚(yáng)程12.5~125m,配用電機(jī)功率0.37~160KW,轉(zhuǎn)速1450r/min和2900r/min。 SPG型管道式屏蔽泵-產(chǎn)品特點(diǎn) 1、泵結(jié)構(gòu)緊湊，機(jī)泵一體化，體積小。其立式結(jié)構(gòu)具有安裝占地面積小，運(yùn)行平衡，安裝無需調(diào)整。 2、泵進(jìn)出口設(shè)計(jì)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(jī)同軸，軸向尺寸短，使泵運(yùn)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(zhì)的外泄，因此具有*無泄漏的顯著特點(diǎn)。 5、用滑動(dòng)軸承替代常規(guī)電機(jī)滾動(dòng)軸承，使泵具有運(yùn)行特別平穩(wěn)，振動(dòng)噪音極低。 6、安裝栓修方便，無需拆動(dòng)管路系統(tǒng)，只要拆下連接體螺母即可抽出全部轉(zhuǎn)子部件進(jìn)行檢查和維修。 7、可根據(jù)使用要求即流量和揚(yáng)程的需要進(jìn)行泵的串、并聯(lián)運(yùn)行方式。 SPG型管道式屏蔽泵-結(jié)構(gòu)說明 結(jié)構(gòu)見圖。該泵為機(jī)泵一體結(jié)構(gòu)，整機(jī)主要由泵體、葉輪、聯(lián)接體、滑動(dòng)軸承、定子、轉(zhuǎn)子、屏蔽套、電機(jī)殼等零部件組成。泵為立式單級(jí)單吸離心式，進(jìn)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(jī)成一體，軸承采用進(jìn)口石墨浸漬樹脂復(fù)合軸承，電機(jī)定轉(zhuǎn)子各有屏蔽套進(jìn)行隔離。軸承采用液體本身介質(zhì)作為潤滑劑及冷卻液，具有設(shè)計(jì)合理、運(yùn)行可靠的特點(diǎn)。泵設(shè)有底座，可直接安裝在地基上，因該泵具有低噪音，無振動(dòng)特點(diǎn)，安裝時(shí)無需加裝隔振器與隔振墊。1泵

SPG型管道式屏蔽泵-安裝說明 1、安裝前應(yīng)檢查機(jī)組緊固件有無松動(dòng)現(xiàn)象，泵體流產(chǎn)內(nèi)有無異物堵塞，以免水泵運(yùn)行時(shí)損壞葉輪和泵體。 2 、安裝時(shí)管路重量不應(yīng)加在水泵上，應(yīng)有各自的支承體，以免泵變形影響運(yùn)行性能和使用壽命。 3 、為了不使雜質(zhì)進(jìn)入泵內(nèi)而堵塞流道影響性能，應(yīng)在泵進(jìn)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(shí)，為了不使泵承受管路的熱變形，泵可以不固定底腳螺栓，當(dāng)管路系統(tǒng)在熱脹冷縮時(shí)，使泵與管路同時(shí)移動(dòng)。 5 、為了維修方便和使用安全，在泵的進(jìn)出口管路應(yīng)各裝上一只調(diào)節(jié)閥門及在泵進(jìn)出口附近各安裝一只壓力表，以保證在額定范圍內(nèi)運(yùn)行，確保泵的正常運(yùn)行和使用壽命。 SPG型管道式屏蔽泵-維護(hù)與保養(yǎng) 一、起動(dòng)前的準(zhǔn)備及檢查： 1、 檢查屏蔽電機(jī)和起動(dòng)設(shè)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(duì)新安裝和*停用的屏蔽電機(jī)，使用前應(yīng)檢查電機(jī)定子繞組對(duì)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(jī)的使用壽命。 二 、運(yùn)行中的維護(hù)保養(yǎng) 1、 定時(shí)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(jī)的過熱或其它不正?，F(xiàn)象。 2、定時(shí)記錄電泵的負(fù)載電流和不平衡度。電泵發(fā)生故障時(shí)大多數(shù)會(huì)反映到定子繞組的電流的劇增，使電機(jī)過熱。 3、定時(shí)記錄管路中的輸液溫度，以確保實(shí)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(yùn)行，而降低電機(jī)的使用壽命。 4、 定時(shí)記錄電泵進(jìn)、出口端上的壓力表數(shù)值，進(jìn)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(jìn)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(yùn)行時(shí)，必須每星期排一次氣。因泵經(jīng)長時(shí)間運(yùn)行，水分子在電泵內(nèi)被高速攪拌和撞擊，同時(shí)被輸送的介質(zhì)帶有一定的溫度故液體漿產(chǎn)生 6、注意電泵的氣味，振動(dòng)和噪聲，電機(jī)的繞組因溫度過高就會(huì)發(fā)出絕緣的焦味。一般的機(jī)械故障會(huì)反映為振動(dòng)和噪聲。因此發(fā)現(xiàn)異常因立即停電檢查。 7、定時(shí)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(zhuǎn)子屏蔽套之間間隙均勻，運(yùn)轉(zhuǎn)可靠。一般情況以下表為限，如超過表中的規(guī)定就應(yīng)修復(fù)或更換。軸套外徑（mm）磨損極限間隙（mm）標(biāo)準(zhǔn)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(huì)直接影響電泵的性能，在一般情況下，間隙超過1.5mm，則應(yīng)更換新的葉輪，在特殊情況下也可采用修補(bǔ)工藝來改善。 SPG型管道式屏蔽泵-起動(dòng)、運(yùn)轉(zhuǎn)和停車 一、起動(dòng)、動(dòng)轉(zhuǎn)： 1、灌水排氣、打開進(jìn)口閥，使液體充分進(jìn)入泵腔內(nèi)，打開電機(jī)頂部排氣閥，待滿后關(guān)閉排氣閥。 2、關(guān)閉出口閥，以減小起動(dòng)電流。 3、檢查各部位是否正常。 4、接通電源，起點(diǎn)動(dòng)確定正確運(yùn)行方向。 5、逐步調(diào)節(jié)出口閥的開度，盡量使泵在額定性能范圍內(nèi)工作。 6、泵的運(yùn)轉(zhuǎn)過程中，如發(fā)現(xiàn)有異常，應(yīng)立即停車檢查排除。 7、檢查電機(jī)電流值及溫升是否符合要求。 二、停車 1、關(guān)閉吐出管路閥門。 2、切斷電源，停止電機(jī)運(yùn)行。 3、關(guān)閉進(jìn)口閥。 4、泵如*停用，應(yīng)放盡泵內(nèi)的液體。 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(chǎn)生的原因排除方法1、水泵不出水1、進(jìn)出口閥門未打開，進(jìn)出管路阻塞葉輪流道阻塞。2、電機(jī)運(yùn)行方向不對(duì)，電機(jī)缺相轉(zhuǎn)速很慢。3、吸入管漏氣。4、泵腔內(nèi)存有空氣。5、進(jìn)口供水不足。6、管路阻力過大，泵選型不當(dāng)。1、檢查，去除阻塞物2、調(diào)整電機(jī)轉(zhuǎn)向，緊固電機(jī)接線3、擰緊各密封面，排除空氣4、打開電機(jī)頂部排氣閥，排盡空氣。5、停機(jī)檢查、調(diào)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(zhuǎn)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(diào)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(yùn)轉(zhuǎn)部件有碰擦。3、滑動(dòng)軸承磨損或破裂。4、介質(zhì)比重過大。
