When the double acting pneumatic actuator air source pressure enters the cavity between the two pistons of the cylinder from the air port (2), the two pistons are separated and moved toward the ends of the cylinder, and the air in the air chambers at both ends is discharged through the air port (4), and the two piston racks are synchronized at the same time Drive the output shaft (gear) to rotate counterclockwise.
The pneumatic actuator adopts compact double-piston gears, rack-and-pinion structure, precise meshing, high efficiency, and constant output torque.
The electric actuator refers to an electrical signal such as an electrical signal such as an energy source in the control system. The amount of manipulation is changed according to the size of the signal, so that the amount of material or energy of the input or output control object changes, reachabable Adjustable.
Electric actuator mechanisms should not immerse water, and wiring must meet on-site construction specifications. 10. Before energization, pay attention to check the power supply voltage required by the electric actuator to avoid damage to the motor. When repairing, you must turn off the power.
. Structural features of explosion-proof full intelligent electric valve actuators: The explosion-proof structure of electric valve actuators and its parts manufacturing are much more complicated than general electrical equipment, mainly in the following aspects: The net volume of the explosion chamber is large, generally exceeded .
Electric actuators apply automatic control systems such as metallurgy, chemical, stone oil, electric power, natural gas and water conservancy; use a large-scale integrated circuit to replace and implement the traditional execution mechanism to achieve only mechanical components.
