1、FD INDUSTRY DEPARTMENT,European Industrial Workshop Big And Blue Pumps In Steel Industry 大型離心泵在歐洲鋼廠的應(yīng)用 Lyon - October 18 - 20 1999,Thorsten Khler,FD工業(yè)部,FD INDUSTRY DEPARTMENT,Centrifugal Pump Or Submersible Pump 離心泵或潛水泵,All parts of industry need pumps for hydraulic haulage sectors. 14 Mio. pumps ar

2、e produced only in Germany p.a. Most of these pumps are centrifugal pumps for dry installation.,e.g. KSB centrifugal pump type: Etanorm 100-250 with 90 KW,工業(yè)領(lǐng)域需要用泵來傳輸液體，過去在德國已經(jīng)生產(chǎn)了1400萬臺泵，單其中大多數(shù)是干式安裝的離心泵,例如：KSB的Etanorn100200（90KW）離心泵,FD INDUSTRY DEPARTMENT,Big centrifugal pumps with motors acc.

3、 are high maintenance products 外置電機(jī)的大型離心泵，IP54又是高維修產(chǎn)品,Often extra listing gear is requested when serve the pumps 需要許多額外的傳動裝置,Alignment of pump and motor takes a lot of time 泵與電機(jī)的對準(zhǔn)需要很長時(shí)間,Couplings have to be changed frequently 聯(lián)軸器需要經(jīng)常維修,FD INDUSTRY DEPARTMENT,Block pumps are servicefriendly but limi

4、ted in their capacity. Therefore often centrifugal pumps with IP 54 motors are chosen for bigger volumes.,Block泵雖然易于裝配和維修，但是容量有限,因此，更多用的還是離心泵帶IP54的電機(jī),Trends in the german industry (I) 德國工業(yè)的新趨勢（I）,FD INDUSTRY DEPARTMENT,Cost pressure in industrial companies causes further reductions in manpower. 為了降低

5、成本要求進(jìn)一步減少人力維護(hù),The further reduction of own service facilities and of spare parts stocks desires products with long lifetimes and low maintenance costs. 進(jìn)一步減少自維護(hù)設(shè)施和備件的儲存，這就要求產(chǎn)品有長生命周期和低維修成本,FD INDUSTRY DEPARTMENT,Trends in the german industry (II)德國工業(yè)的新趨勢（II）,Engineering and design work for industrial
