<strong>進(jìn)口立式雙吸離心泵</strong>

一、進(jìn)口立式雙吸離心泵產(chǎn)品概述

美國尼科NICO進(jìn)口立式雙吸離心泵(原來也稱中開型),使用雙吸式葉輪,并且泵可以中間剖開,故稱為雙吸中開式離心泵。美國尼科NICO結(jié)合用戶使用習(xí)慣和使用難點優(yōu)化之后研發(fā)的泵種。供抽送清水或物理化學(xué)性質(zhì)類似于清水的其它液體之用。要求被輸送液體溫度≤80℃。標(biāo)配填料密封,可選配機械密封。因其可以中間剖開的特性,檢修維修十分方便。深受廣大用戶的喜愛。第二代水力模型更優(yōu)按API610 BB1結(jié)構(gòu)化工系列單級雙吸、水平中開式離心泵,溫度范圍:<80℃,底腳支撐,油潤滑,效率更高,可供廣大用戶比較選擇。高溫系列、單級雙吸水平中開離心泵;溫度范圍: 80~150℃,溫度>120℃采用中心支撐。

二、進(jìn)口立式雙吸離心泵選型參數(shù)

公稱通徑:25~1000mm

流量范圍:9180m3/h

揚程范圍:5~55m

功率范圍:1.5~135KW

轉(zhuǎn)速范圍:740-2900r/min

溫度范圍 :-20℃~150℃

工作壓力:≤1.6Mpa

泵體材質(zhì):WCB、304、316、四氟

三、進(jìn)口立式雙吸離心泵特點

本型泵的吸入口與吐出口均在水泵軸心線下方,水平方向與軸線成垂直位置,泵殼中開,檢修時無需拆卸進(jìn)水、排出管路及電動機(或其他原動機)。從聯(lián)軸器向泵的方向看去,水泵為逆吋針方向旋轉(zhuǎn)。如根據(jù)用戶訂貨需要也可改為順吋針旋轉(zhuǎn)。

本型泵的主要零部件有:泵體、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套、軸承等。

泵體與泵蓋構(gòu)成葉輪的工作室,在進(jìn)出水法蘭上制有安裝真空表和壓力表的管螺孔,進(jìn)出水法蘭的下部制有放水的管螺孔。

葉輪經(jīng)過靜平衡校驗,用軸套和兩側(cè)的軸套螺母固定,其軸向位置可以通過軸套螺母進(jìn)行調(diào)整,葉輪的軸向力利用其葉片的對稱布置達(dá)到平衡,可能還有一些剩余軸向力則由軸端的軸承承受。

泵軸由兩個單列向心球軸承支承,軸承裝在泵體兩端的軸承體內(nèi),用黃油潤滑,雙吸密封環(huán)用以減少水泵壓水室的水漏回吸水室。

水泵通過聯(lián)軸器由電動機直接傳動。

軸封為軟填料密封,為了冷卻潤滑密封腔和防止空氣漏入泵內(nèi),在填料之間有水封環(huán),水泵工作時小量高壓水通過水封管流入填料腔起水封作用。

九、進(jìn)口立式雙吸離心泵說明

●為清水常規(guī)配置:為特殊介質(zhì)或特殊工況的選配,高效節(jié)能雙吸泵技術(shù)優(yōu)勢

●優(yōu)勢一高效率:引進(jìn)國內(nèi)外秀水力模型,采用CFD計算流體動力學(xué)分析方法,針對性地進(jìn)行優(yōu)化分析改進(jìn);性能指標(biāo)超越行業(yè)水平,達(dá)到*水平,率突破92%。

●優(yōu)勢二低脈動:采用兩半葉輪葉片交錯布置結(jié)構(gòu),從而改變?nèi)~頻(葉片通過泵體隔舌頻率),使得液流脈沖降低(約降低揚程的1%。~4%o),液流更加平穩(wěn),效率更高、振動更小、運行更加平穩(wěn)可靠。

●優(yōu)勢三低汽蝕余量:葉片進(jìn)口邊形狀采用凸弧形優(yōu)化設(shè)計,增加液流進(jìn)口過流面積,降低進(jìn)口流速,使得進(jìn)口邊壓力增加,從而提高汽蝕余量。葉片頭部采用翼型流線設(shè)計,使得液流沖擊損失減少,漩渦減少,不但提高了點效率值,同時使得高效區(qū)更加寬廣,壓力分布均勻,汽蝕性能更佳。

●優(yōu)勢四高可靠性:高揚程泵采用雙蝸殼設(shè)計,泵體、泵蓋均設(shè)置加強筋,并采用ANSYS力學(xué)分析軟件優(yōu)化結(jié)構(gòu),泵殼具有很高的強度,軸承跨距短,軸加粗設(shè)計,使得轉(zhuǎn)子運轉(zhuǎn)時擾度小,穩(wěn)定可靠。所有葉輪均做6.3級靜平衡試驗,整個轉(zhuǎn)子按API610標(biāo)準(zhǔn)做2.5級動平衡試驗。主軸采用不接觸液體的全密封式設(shè)計,軸承部件設(shè)置唇形油封+V型密封圈組合密封結(jié)構(gòu),具有優(yōu)秀的防漏油、防灰塵、防水、防濕氣功能。

●優(yōu)勢五強適應(yīng)性:

泵高效區(qū)寬,能更大范圍滿足用戶要求;另外,我們采取一泵兩輪的葉輪配置方式使得泵具有非常好的可選性,能絕大部分保證用戶的工況點都能選到高效范圍。

泵進(jìn)、出口法蘭可按照GB、ISO、DIN、BS、ANSI等標(biāo)準(zhǔn)加工。

泵殼流道:可進(jìn)行超滑節(jié)能涂層、耐磨耐腐涂層等選擇。輸送高溫介質(zhì)可采用CPS-R型結(jié)構(gòu),泵采用中心支撐、水冷軸承體。

軸封系統(tǒng):可實現(xiàn)填料密封、單端面密封互換,也可按用戶要求配置集裝式機封、雙端面機封以及配置AP1682標(biāo)準(zhǔn)的沖洗系統(tǒng)。

軸承潤滑系統(tǒng):可采用脂潤滑或稀油潤滑供靈活選擇。

軸承冷卻系統(tǒng):可根據(jù)介質(zhì)溫度高低選擇自然冷卻或水冷卻軸承體。

遠(yuǎn)程監(jiān)控:軸承體設(shè)置測溫、測振等監(jiān)測接口,可方便實現(xiàn)遠(yuǎn)程監(jiān)控。

●優(yōu)勢六高通用化:除泵體、泵蓋、葉輪等少數(shù)零件外,其余均采用模塊化設(shè)計,實現(xiàn)了零件的標(biāo)準(zhǔn)化,同軸系的軸承部件、密封部件、軸套、擋套等均可實現(xiàn)互換,方便實現(xiàn)泵的量產(chǎn)。
