Embodiment Construction

[0037] The system flow accuracy index is RSD=0.06%, the pulsation rate index is 0.3MPa, and the maximum operating pressure of the system is 120MPa. For example, the change of the mixing ratio of different liquids during the operation of the liquid phase pump will lead to changes in the system pressure. In order to ensure the smoothness of the gradient curve and the accuracy of the concentration ratio, it is necessary to change the motion parameters of the multi-axis motor in each cycle. The accuracy and low pulsation of the process flow, the multi-axis motion need to maintain a certain coupling coordination and the compression coefficient needs to be adjusted dynamically. Therefore, the entire control system must realize the rapidity and accuracy of information flow transmission to ensure that the concentration ratio of the gradient process is accurate and stable according to the set method.
