大型离心泵在欧洲钢厂的应用p.ppt

1、FD INDUSTRY DEPARTMENT,European Industrial Workshop Big And Blue Pumps In Steel Industry 大型离心泵在欧洲钢厂的应用 Lyon - October 18 - 20 1999,Thorsten Khler,FD工业部,FD INDUSTRY DEPARTMENT,Centrifugal Pump Or Submersible Pump 离心泵或潜水泵,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,工业领域需要用泵来传输液体，过去在德国已经生产了1400万台泵，单其中大多数是干式安装的离心泵,例如：KSB的Etanorn100200（90KW）离心泵,FD INDUSTRY DEPARTMENT,Big centrifugal pumps with motors acc. IP 54

3、 are high maintenance products 外置电机的大型离心泵，IP54又是高维修产品,Often extra listing gear is requested when serve the pumps 需要许多额外的传动装置,Alignment of pump and motor takes a lot of time 泵与电机的对准需要很长时间,Couplings have to be changed frequently 联轴器需要经常维修,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泵虽然易于装配和维修，但是容量有限,因此，更多用的还是离心泵带IP54的电机,Trends in the german industry (I) 德国工业的新趋势（I）,FD INDUSTRY DEPARTMENT,Cost pressure in industrial companies causes further reductions in manpower. 为了降低

5、成本要求进一步减少人力维护,The further reduction of own service facilities and of spare parts stocks desires products with long lifetimes and low maintenance costs. 进一步减少自维护设施和备件的储存，这就要求产品有长生命周期和低维修成本,FD INDUSTRY DEPARTMENT,Trends in the german industry (II)德国工业的新趋势（II）,Engineering and design work for industrial

6、 projects are being passed on more and more to the supplier. 工业项目的工程和设计工作越来越多的转移给供货商,Advantages of submersible pump horizontal dry installation with mobile stand in contrast to conventional pump technique (I) 潜水泵干式卧式安装与传统的干式安装泵相比的技术优势(I),FD INDUSTRY DEPARTMENT,CZ-Installation with mobile stand Z式卧式安

7、装,(back-pull out design),No coupling between hydraulics and motor 水力部件与电机之间无联轴器,No problems of vibrations 无振动问题,No need of alignment and minutes of vibration 无需对准和偏差纠正,Maintenance is possible without lifting appliances and without disconnecting the suction pipe and pressure line 维修时无需提升设备，无需将吸入管与压力部

8、件分开,FD INDUSTRY DEPARTMENT,Advantages of submersible pump horizontal dry installation with mobile stand in contrast to conventional pump technique (II) 潜水泵干式卧式安装与传统的干式安装泵相比的技术优势(II),(back-pull out design),Noiseless working 无噪音,Less need of room 所需泵房结构简单,Secure of flooding 抗水淹,Less mechanical / dynam

9、ical internal wear and tear 动力和机械磨损小,CZ-Installation with mobile stand Z式卧式安装,Investment and life cycle costs of centrifugal pump in contrast to submersible pump in dry installation 潜水泵干式安装和传统离心泵的投资与生命周期成本比较,FD INDUSTRY DEPARTMENT,Investment- and life cycle costs DM投资和生命周期成本,year年,1,2,3,4,5,Submersi
