- Abstract:
- In the design phase of new construction and renovation of rainwater pumping stations, it is essential to assess the water flow stress on the shaft base equipped with submersible axial flow pumps to calculate the design load for structural profession. Typically, the relevant engineers design the civil structure based on the data provided in the manufacturer’s pump sample; however, it is important to note that this data is derived from specific experimental conditions and lacks generalizability. Consequently, the stress was analyzed through engineering case studied and in accordance with the installation configuration and operational conditions of the DN1 100 steel shaft supporting the 700QZ-70G submersibleaxial flow pump, and the water flow stress exerted on the shaft base of the submersible axial flow pump was accurately calculated utilizing both Bernoulli’s equation and the momentum equation under constant total flow conditions, thereby providing valuable insights for the economical and rational design of pumping station structures.
