DFP型不銹鋼自平衡離心泵產(chǎn)品概述:
DFP型不銹鋼自平衡離心泵為臥式、單吸、多級、節(jié)段式耐腐蝕化工離心泵,是化工泵廠家中聯(lián)泵業(yè)研發(fā)的一款高效節(jié)能高溫高壓多級離心泵產(chǎn)品,用于輸送不含固體顆粒、溫度低于80°C的腐蝕性液體,泵進(jìn)口允許壓力<0.6MPa。臥式多級化工泵采用不銹鋼材質(zhì)鑄造,耐腐蝕性能強,實用安全性、經(jīng)濟性、運行能力以及低的維修費用。用戶可根據(jù)輸送介質(zhì)的名稱。濃度、比重、使用溫度及泵進(jìn)口壓力等合理選用泵的材質(zhì)、密封形式、泵的結(jié)構(gòu)和確定電機的功率等。
DFP型不銹鋼自平衡離心泵型號意義
例:DFP85-80x10
DFP——表示自平衡耐腐臥式多級化工泵
85——表示泵的設(shè)計點流量
80——表示泵的單級設(shè)計點揚程
10——表示泵的級數(shù)
DFP型不銹鋼自平衡離心泵主要結(jié)構(gòu)
DFP型不銹鋼自平衡離心泵屬于自平衡多級泵,為單吸或雙吸進(jìn)口的臥式節(jié)段式多級離心泵,泵的吸入口可以垂直向上或水平、排出口垂直向上布置。主要有:進(jìn)水段、中段、出水段、次級進(jìn)水段、正導(dǎo)葉、反導(dǎo)葉、正葉輪、反葉輪、軸、節(jié)流、減壓裝置、擋套、軸承體、過渡管等零件組成;中段由高強度的穿杠螺栓和進(jìn)出水段聯(lián)接,泵的進(jìn)水段、中段、出水段之間的密封面均采用二硫化鉬潤滑脂金屬面硬密封;轉(zhuǎn)子由裝在軸上的正葉輪、節(jié)流減壓裝置、反葉輪、軸套、軸承擋套等零件組成;軸承采用“固-游式”干油潤滑結(jié)構(gòu),驅(qū)動端采用圓柱滾子軸承,末端采用角接觸球軸承;泵的工作室由進(jìn)水段、中段、出水段、次級進(jìn)水段、正導(dǎo)葉、反導(dǎo)葉、過渡管等組成。

DFP型自平衡臥式多級化工泵轉(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)及時予以更換;
軸的密封形式有機械密封和填料密封兩種。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腔內(nèi),腔內(nèi)要通入一定壓力的水,起水封、水冷及水潤滑作用。在軸封處裝有可更換的軸套,以保護泵軸;
泵可以在不拆卸進(jìn)、出口管路的情況下更換軸承、密封。
該系列泵通過彈性柱銷聯(lián)軸器或膜片聯(lián)軸器由原動機直接驅(qū)動。從原動機方向看,泵為順時針方向旋轉(zhuǎn)。

DFP型自平衡臥式多級化工離心泵VS平衡盤式臥式多級化工泵
DFP型自平衡臥式多級化工離心泵性能
1、*的組合模塊化的設(shè)計,大量使用經(jīng)過長期運行考驗的局部組件,零部件具有高度的可互換性。
2、高強度、高質(zhì)量材料以及多種選擇的進(jìn)、出口法蘭和接管設(shè)計,提高了泵很高的許用接管載荷,高強度、高質(zhì)量泵殼結(jié)構(gòu)材料結(jié)構(gòu)緊密使用壽命是普通鑄件的5倍,過流部位葉輪、導(dǎo)葉采用精密鑄造,光滑平整比普通鑄件效率提高2%以上??呻S時滿足用戶特殊情況下系統(tǒng)的特定要求。
3、快速的裝配和拆卸設(shè)計,允許水泵在不拆卸泵體和進(jìn)、出口管路的情況下更換密封、軸承部件,保證了少的大修和檢查時間。
4、高效率、高可靠性、低成本的組合。通過葉輪和導(dǎo)葉的搭配,以及合理的配合間隙和較寬的軸向節(jié)流設(shè)計,使ZPD型高壓多級離心泵在長期運行后仍然能保持其高度的穩(wěn)定性和的運行效率。
5、對稱布置葉輪的轉(zhuǎn)子部件,轉(zhuǎn)子部件上葉輪分高低壓區(qū)兩端,軸向力相互抵消而平衡,泵變工況運行的瞬時軸向力和因加工誤差及螺旋密封而產(chǎn)生的殘余軸向力,由軸承部件的推力承載機構(gòu)承擔(dān),該類泵取消了平衡盤或平衡鼓等軸向力平衡機構(gòu),避免免了因泵工況變化瞬時,平衡盤或平衡鼓失效造成轉(zhuǎn)子抱死、零件損壞、斷軸、甚至燒毀電機事故的發(fā)生。
安全的泵體密封設(shè)計。根據(jù)不同l 的壓力及結(jié)構(gòu),泵體采用金屬面對金屬面的硬密封或O型圈密封。根據(jù)用戶要求,可增加中間抽頭及最小流量系統(tǒng)。泵可以在不拆卸進(jìn)、出口管路的情況下更換軸承、密封。
6、良好的汽蝕性能。采用優(yōu)秀的葉輪水力模型或特殊的雙吸葉輪結(jié)構(gòu),用戶無需另外配置前置泵或提高進(jìn)水箱的高度。
DFP型自平衡臥式多級化工離心泵主要優(yōu)勢
DFP型不銹鋼化工離心泵采用對稱布置,取消平衡裝置可基本消除軸向力,殘余軸向力由一對背靠背的角接觸球軸承承受。由于無平衡裝置,即無平衡盤的園盤摩擦損失又無平衡回流損失,所以泵效率比同類別多級泵提高3%—14%,由于無平衡裝置,解決因平衡裝置失效而導(dǎo)致泵平衡盤和平衡盤座的磨損或轉(zhuǎn)子咬死等各種故障,大大延長泵的使用壽命。的結(jié)構(gòu)強度設(shè)計。允許泵的單級揚程達(dá)1.5Mpa (150m),出口壓力可達(dá)15Mpa(總揚程1500m),并且使軸承和轉(zhuǎn)子組成的芯包部件不受溫度變化的影響,具有優(yōu)秀的抗熱沖擊性能。
