AI Technical Summary
Technical Problem
When existing rotary drilling rigs perform compound operations, multiple hydraulic pumps in the hydraulic system drive each execution unit separately, resulting in uncoordinated actions among the execution units and making it difficult to achieve precise control.
Method used
A composite motion control system is adopted. The action pressure of the actuator is obtained through the pressure unit. The controller determines the target current based on the pressure and controls the flow of the solenoid valve to achieve precise distribution of fluid medium.
Benefits of technology
It improves the working efficiency and availability of rotary drilling rigs and enables precise control of complex actions.
