The composition of the intelligent integrated electric actuator is as follows:
1. Housing: The housing is made of hard aluminum alloy, anodized and polyester powder coating, with strong corrosion resistance, protection grades IP67, NEMA4 and 6, and IP68 and explosion-proof options are available.
2. Motor: fully enclosed squirrel-cage motor, small size, large torque, small inertia force, insulation class F, built-in overheat protection switch, can prevent overheat damage to the motor.
3. Manual structure: The design of the handwheel guarantees safety, reliability, labor saving and small size. When the power is off, the clutch handle can be operated manually. When power is applied, the clutch is automatically reset. (Note: When the motor is not energized, the electric actuator will remain permanently manual)
4. Indicator: The indicator is installed on the central axis, and the valve position can be observed. The mirror surface is designed with a convex lens, which does not accumulate water and is more convenient to observe.
5. Dryer: It is used to control the temperature, prevent the moisture inside the actuator from condensing due to temperature and weather changes, and keep the internal electrical components dry.
6, limit switch: mechanical, electronic double limit. The mechanical limit screw is adjustable, safe and reliable; the electronic limit switch is controlled by the cam mechanism, and the simple adjustment mechanism can set the position accurately and conveniently without battery support. (Micro switch contacts are silver contacts)
7. Torque switch: It can provide overload protection. When the valve is stuck or there is a foreign object, it will automatically disconnect the power of the motor, which can more effectively protect the valve and electric actuator from damage. (Already set before leaving the factory, please do not change the setting at will)
8. Self-locking: The precision double worm gear and worm gear mechanism can efficiently transmit large torque, high efficiency, low noise (maximum 50 dB), long life with self-locking function, preventing reverse rotation, stable and reliable transmission parts, and the factory has been filled with efficient lubrication Fat, no need to refuel.
9. Anti-drop bolts: When the shell is removed, the bolts are attached to the shell and will not fall off. The outer bolts are made of stainless steel.
10. Digital display of valve position: During the opening or closing of the actuator, the valve position changes are displayed on the LCD screen in large digital real-time.
