Abstract
The invention relates to an integrated petroleum drilling throttle valve electric actuating device, which is characterized in that an electric cylinder is connected with an explosion-proof motor, and an integrated servo driver is connected with the explosion-proof motor through an explosion-proof joint and is used for transmitting power and control signals to the explosion-proof motor after the power and control signals are processed by the integrated servo driver; and the explosion-proof motor directly drives the electric cylinder to realize linear motion according to the instruction signal. According to the invention, the servo motor, the planetary roller screw and the programmable servo driver are integrated into a whole. The design simplifies the system structure, improves the compactness and reliability of the system, and has the advantages of higher control precision, lower maintenance cost, longer service life and the like. Meanwhile, a programmable servo driver is also integrated on the electric actuating device, the bottom hole pressure and the working state in the drilling process are monitored in real time through motor feedback, the operating parameters of the actuating device are automatically adjusted, and safe and efficient drilling operation is guaranteed.
