AI Technical Summary

Technical Problem

Existing lifting water tank devices have slow response speed, small pressure range, and low accuracy when simulating unsteady seepage processes, making it difficult to reproduce complex flow conditions in actual engineering projects. In particular, they pose difficulties in studying the undercutting process under high water head and large fluctuation conditions.

Method used

The device employing PID control includes a power supply module, a PID control module, a pressure output module, and supporting control software. By monitoring and dynamically adjusting the operating power of the water-oil mixing pump in real time, it achieves precise control of seepage pressure and can simulate seepage pressure changes under stable or unstable operating conditions.

Benefits of technology

It enables precise adjustment of seepage pressure, accurately simulates unsteady flow conditions in actual engineering under complex flow conditions, and improves the accuracy and reliability of the research.
