詳細(xì)介紹

一、進(jìn)口臥式多級管道泵產(chǎn)品概述

美國尼科NICO進(jìn)口臥式多級管道泵系列臥式、單吸多級、分段式結(jié)構(gòu),是新開發(fā)生產(chǎn)的節(jié)能系列產(chǎn)品。具有效率高,運行噪音低,抗汽蝕性能好,結(jié)構(gòu)合理,使用壽命長等顯著優(yōu)點。主要輸送清水或物理化學(xué)性質(zhì)類似于水的其他液體。該系列泵轉(zhuǎn)子部分主要由軸及安裝在軸上的葉輪、軸套、平衡盤等零件組成,其中葉輪的數(shù)量根據(jù)泵的級數(shù)而定。軸上零件用平鍵和軸螺母緊固使之與軸成為一體。整個轉(zhuǎn)子由兩端滾動軸承或滑動軸承支承。軸承按型號不同而定,均不承受軸向力,其軸向力由平衡盤平衡。泵在運行中允許轉(zhuǎn)子在泵殼中軸向游動,不能采用向心球軸承。滾動軸承用油脂潤滑,滑動軸承用稀油潤滑,并用油環(huán)進(jìn)行自潤滑,循環(huán)水冷卻。泵的吸入段、中段、吐出段之間的密封面均采用二硫化鉬潤滑脂密封,轉(zhuǎn)子部分與固定部分之間裝有密封環(huán)、導(dǎo)葉套等進(jìn)行密封,當(dāng)密封環(huán)和導(dǎo)葉套的磨損程度已影響泵的工作性能時應(yīng)予更換。軸的密封形式有機械密封和填料密封兩種。WSDJ大多采用填料密封,PXDJ一般采用機械密封。泵采用填料密封時,填料環(huán)的位置安放要正確,填料的松緊程度必須適當(dāng),以液體能一滴一滴滲出為宜。泵各種密封元件裝在密封箱內(nèi),箱內(nèi)要通入一定壓力的水,起水封、水冷或水潤滑作用。軸封處裝有可更換的軸套,保護(hù)泵軸。

三、進(jìn)口臥式多級管道泵工作原理

臥式多級泵為多級分段式,其吸入口位于進(jìn)水段上,成水平方向,吐出口在出水段上垂直向上,其揚程可根據(jù)使用需要而增減水泵級數(shù)。水泵裝配良好與否,對性能影響關(guān)系很大,尤其是各個葉輪的口出與導(dǎo)翼的進(jìn)出中心,其中稍有偏差即將使水泵的流量減少,揚程降低效率差,故在檢修后裝配時務(wù)必注意。 WSDJ水泵的主要零件有:進(jìn)水段、中段、出水段、葉輪、導(dǎo)翼擋板、出水段導(dǎo)翼、軸、密封環(huán)、平衝盤、軸套、尾蓋及軸承體。 進(jìn)水段、中段、導(dǎo)葉擋板、出水段導(dǎo)翼、出水段及尾蓋均為銹鐵制成,共同形成泵的工作室。 葉輪為優(yōu)質(zhì)銹鐵制成,內(nèi)有葉片,液體沿軸向單側(cè)進(jìn)入,由于葉輪前后受壓不等,必然存在軸向力,此軸向力由平衝盤來承擔(dān),葉輪制造時經(jīng)靜平衡試驗。 軸為優(yōu)質(zhì)炭素鋼制成,中間裝有葉輪,用鍵、軸套及軸套螺母固定在軸上。軸的一端裝聯(lián)軸器部件,與電 機直接連接。 密封環(huán)為銹鐵制成,防止水泵高壓水漏回進(jìn)水部分,分別固定在進(jìn)水段與中段之上,為易損件,磨損后可用備件更換。 平衡環(huán)為鑄鐵制成,固定在出水段上,它與平衡盤共同組成平衝裝置。 平衡盤為耐磨銹鐵制成,裝在軸上,位于出水段與尾蓋之間,平衡軸向力。 軸套為銹鐵制成,位于填料室處,作固定葉輪和保護(hù)泵軸入用,為易損件,磨損后可用備件更換。 軸承是單列向心球軸承,采用鈣基潤滑脂潤滑。填料起密封作用,防止空氣進(jìn)入和大量液體漏出,填料密封由進(jìn)水段和尾蓋上的填料室,填料壓蓋,填料環(huán)及填料等組成,少量高壓水流入填料室中起水封作用。填料的松緊程度必須適當(dāng),不可太緊亦不可太松,以液體能一滴一滴的滲出為準(zhǔn)。如果填料太緊,軸套容易發(fā)熱,同時耗費功率。填料太松,由于液體流失要降低水泵的效率。
