Freya Electric Actuator is a brand-new self-developed product. By referring to the previous mature products the technical research staff digest and absorb the, design and manufacturing technologies of the foreign advanced electric actuators. They succeed in integrating such latest automation technologies as fieldbus technology absolute coding technology, remote control and magnetic switch control technologies into this new product. The product is composed of CLZ model multi-turn electric actuator and CLQ model part-turn electric actuator.
Classified according to actuator control performance: ordinary type and intelligent type:
Classified according to operation modes,the intelligent type includes: intelligent on-off type and intelligent control type. The intelligent on-off type is used for full-opening or full-closing operation of the driven device. The intelligent control type is used for the operation in which the driven device needs to stop and start at any middle position and carry out precise control. The output travel of the multi- turn actuator series is more than one turn. The theoretical maximum number of turns is 3600 turns, and it is provided with self-locking function.
Classified according to actuator control modes: outdoor type and explosion-proof type.
Product Structural Features
Power transmission
The power transmission of the actuator adopts the precise speed reducing mechanism composed of bronze alloy worm gear and alloy steel worm. The worm gear and worm run in the lubricating grease separately to be adapted to the maximum environmental temperature difference and prolong the service life to the utmost extent.
Driving motor
The motor is a low-inertia and high-torque motor, so that the peak torque can be rapidly reached when the motor is started. There is almost no over-limit movement when there is no excitation. The motor is provided with accurate temperature sensors. Overtemperature limit values can be set through the control system to avoid burning caused by motor overheating.
Housing anti-corrosion
The exterior surface of the actuator adopts special metal painting for aluminum alloy with tough painting film and strong adhesion. With very strong resistance to ultraviolet and corrosion and high fullness, it can completely enhance the service life and selfcleaning performance of the coating, and is suitable for various severe production environments.
Terminal box
The independent sealed terminal cavity can ensure closure integrity of the electrical part in the electric actuator during field wiring and also guarantee that the explosion-proof requirements are met.
Output connection
The actuator flange meets the ISO5210/5211 (GB12222/12223) standard, and flange
connections that meet the JB2920 standard can also be supplied. We can also provide customized products according to customer requirements
Sealing structure
The actuator adopts a double sealing design structure to ensure that the actuator is totally resistant to water and dust. The standard product protection grade is IP67, with the maximum reaching IP68.
