Abstract：
Presents some types of flow rate regulation in variable flow rate hydraulic systems and the operating principle and function of constant pressure difference techniques. Analyses the reason that the constant pressure difference technology at key points can be used in variable flow rate systems to realize the all hydraulic balance. With some actual projects, presents the application of the constant pressure difference technique at key points.
