轉(zhuǎn)速范圍:2900r/min
溫度范圍 :-15∽380℃
工作壓力:≤1.6Mpa
泵體材質(zhì):WCB、304、316
三、進(jìn)口管道屏蔽泵特點
進(jìn)口管道屏蔽泵電機(jī)選用H級絕緣繞組。轉(zhuǎn)子由不銹鋼軸和鑄鋁轉(zhuǎn)子組成。為了防止輸送液體進(jìn)入定子和腐蝕轉(zhuǎn)子,在定子內(nèi)徑及轉(zhuǎn)子表面分別用不銹鋼屏蔽套密封。
密封性:泵體法蘭與電機(jī)法蘭連接處,機(jī)座與軸承座及定子屏蔽連接處均有耐熱O型密封圈密封。
屏蔽泵葉輪懸臂安裝在電機(jī)轉(zhuǎn)軸上,由鍵和螺母予以固緊。
潤滑與冷卻:采用外循環(huán)。當(dāng)泵工作時,由電泵出口處引出少量液體經(jīng)過冷卻管、后軸承與軸頸間隙、定、轉(zhuǎn)子間隙、前軸承與軸頸間隙、葉輪后口環(huán)組成一循環(huán)回路(單級)、后一級葉輪進(jìn)口環(huán)組成一循環(huán)回路(多級)。
1、進(jìn)口管道屏蔽泵因能保證不泄漏,故可輸送對人體和環(huán)境,設(shè)備有害的及價格昂貴的易泄漏的液體。
2、不會吸入空氣,適于真空系統(tǒng)及輸送與空氣接觸發(fā)生變質(zhì)的液體。
3、無油封設(shè)計,能可靠地輸送一般泵難以輸送的高溫,高壓,低溫及溫度壓力變化的液體。
4、軸承利用輸送液體自行潤滑,不需潤滑油,故不污染輸送液體,并免去了定期注油的麻煩。
5、泵結(jié)構(gòu)合理,電機(jī)和泵同軸,體積小,重量輕,占地面積小,運行平穩(wěn),安裝方便,無須調(diào)整,維修方便,無須調(diào)整,維修方便。
6、葉輪采用水推力平衡式設(shè)計,使轉(zhuǎn)子在運行中可以處于懸浮設(shè)計,降低了石墨軸承的國軸向磨損,從而提高了使用壽命,降低了運行成本。
7、電機(jī)無冷去風(fēng)扇,故運行噪音和振動都非常小。
8、泵進(jìn)出口法蘭的規(guī)格設(shè)計與標(biāo)準(zhǔn)閥門相同,且位于同一中心線上,中心低,便于管道布置,泵房設(shè)計也便為合理,實用。
9、零部件的標(biāo)準(zhǔn)化,系列化程度高。
10、接線盒采用防水結(jié)構(gòu),可在戶外安全使用。
11、可根據(jù)使用要求,即流量和揚程的需要進(jìn)行泵的串,并聯(lián)運行方式。
12、新采用的石墨軸承,具有耐磨性能高、磨擦系數(shù)低,不老化,抗泥沙等優(yōu)點。
四、進(jìn)口管道屏蔽泵工作調(diào)節(jié)
1、介質(zhì)必須為軟水,稀薄,不凝固,非易燃,不含固體顆粒及纖維的流體。
2、進(jìn)口管道屏蔽泵介質(zhì)溫度不超過90度,進(jìn)口管道屏蔽泵泵介質(zhì)溫度不超過380度。
3、一般情況下系統(tǒng)工作壓力不超過1。2MPa,進(jìn)口壓力不小于0.05mpa,特殊場合應(yīng)事先與本公司聯(lián)系。
4、進(jìn)口管道屏蔽泵系統(tǒng)壓力1.6MPa,即水泵的吸入壓+泵揚程≦1.6MPa。

八、進(jìn)口管道屏蔽泵維護(hù)
進(jìn)口管道屏蔽泵一般輸送介質(zhì)溫度可達(dá)350℃,流量可達(dá)300m3/h,揚程可達(dá)115m,適用于熱介質(zhì)油和熱水等高溫液體。
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(jī)的過熱或其它不正常現(xiàn)象。
2、定時記錄電泵的負(fù)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(jī)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,避免電泵長期處于超溫狀態(tài)下運行,降低電機(jī)的使用壽命。
4、定時記錄電泵進(jìn)、出口端上的壓力表數(shù)值,進(jìn)口處力表的數(shù)值不得小于零,出口處壓力表數(shù)與進(jìn)口處壓力表數(shù)的差值,必須符合牌上的規(guī)定的壓力值。
5、電泵在每一次使用前要排氣一次,在長期運行時,必須每星期排一次氣,因為泵長時間運行,水分子在電泵內(nèi)高速攪拌和撞擊,同時被輸送的介質(zhì)帶有一定的溫度,造成液體漿產(chǎn)生。
6、注意電泵的氣味,振動和噪聲,電機(jī)的繞組因溫度過高就會發(fā)出絕緣的焦味。一般的機(jī)械故障會反映為振動和噪聲。因此發(fā)現(xiàn)異常應(yīng)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(zhuǎn)子屏蔽套之間間隙均勻,運轉(zhuǎn)可靠。
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。
