Parallel session: 15D. Special session: Design of intake stations
Intake and pump design development is an ongoing process mainly conditioned by technical and economical requirements. Particularly the conflict between the demand of increasing flow rates of pumping stations and the need of price reduction makes intake design processes more and more complex. Especially for sewage water pumping stations this development is a worldwide challenge. As established standards and most planning data don`t follow this changes – often they can’t follow due to singular edge conditions –, basic research is necessary to develop new designs and optimized evaluation criteria. Physical model investigations are common practice and the best tool of prediction to evaluate, to optimize and to document flow conditions inside intake structures for pumping systems. In addition numerical analysis can be part of design and optimization processes. As optimization steps should be accomplished with respect to installation costs and complexity on site, manufactures and institutes should work together from the earliest possible point of a project. Later changes of already build structures or pumps are very expensive and time consuming. Not to mention downtime costs of plants or factories, caused by pumping station failure. This extended abstract shows some examples how pump and intake designs can be developed and optimized in cooperation work between pumping station and pump manufacturers. Although the pump design is normally not affected, pump manufactures can provide engineering services to the intake design process.
