Based on experimentresearch and model conversion of model device on its 30 incline axial flow pump,it foundthat the comprehensive characteristic curves of model device and reality device,it will beimportant to the design of Xing-Xiagang and other same type pump stations.

Based on similitude theory and hydrodynamics,the device model of tubular pumping station in Huangmayong is set up.

In order to make the Jiangdu fourth pumping station run stably and safely,three high frequency vibration accelerometers were adapted to measure the vibration characteristics of the device model,and the measurement results were analyzed using RMS of vibration acceleration.

The establishment of this model test equipment for sewage dilution and diffusion of ocean disposal includes the model experiment theory foundation,the design and manufacture of the test equipment,the tide control system,data collection system,calibration of the test equipment,and so on.

The ROI (Return of Investment) was adopted as the optimum target of the materiel front deploying model, and a related factor analysis method was put forward to analyze the model into some related factor sub-model.
