https://doi.org/10.1007/978-3-642-97879-1 such as described in this chapter. The first design created that way is then subject to analysis and optimization by CFD. Even then the accuracy of performance prediction is not always satisfactory. This, because the 3D-flow through the pump depends on the complex shapes of the flow paths given by大门在汇总 发表于 2025-3-25 15:50:20

Grundlagen der Linearen Optimierung,e significant for appropriate sizing of shaft and bearings. While the radial force is determined by the pressure distribution ., the axial force is governed by the flow through the impeller sidewall gaps and the resulting pressure distributions on the shrouds.斜谷 发表于 2025-3-26 00:39:49

Der natürliche Mensch und sein Impulssystemich ensure that the pump operates in the range between the allowable minimum and maximum flow - in particular if pumps are operated in parallel. Proper procedures must be implemented for start and stop. Transient operation and unsteady phenomena which need attention include: dynamic instabilities ca碳水化合物 发表于 2025-3-26 12:01:26
Alles Bisherige zusammengepackt!pumping-brake mode”. There are a number of other abnormal modes of operation which are described by the “general characteristics”. These include a turbine mode where the liquid transfers power to the rotor, which can be used to drive an electrical generator or any other machine.Genteel 发表于 2025-3-26 15:23:55
