electric actuator
The non-permeable push button switch operation panel is adopted to achieve a complete waterproof and dustproof structure.
· When the torque switch is sensed, the status quo maintenance function is added.
· LCD liquid crystal display screen, data monitoring function.
Fieldbus (Profibus-DP) communication function.
Product advantages
Double-layer sealing structure, all-weather waterproof (IP68), explosion-proof structure
All parts adopt double-layer sealing structure with O-ring and V-ring, which meets IP68 (72 hours waterproof under 8 meters diving) standard, ensures moisture-proof, dust-proof, and has enough flame-proof channel to prevent the spread of flame. These structures will meet your requirements of high quality, safety and durability.
Multi-unit structure
The functional units that make up the electric actuator are independent of each other, easy to remove and combine at will, and can be conveniently expanded.
Independent handwheel shaft, side-mounted structure
Electric actuator, manual control is achieved by hand swinging, the handwheel is directly meshed with the worm through the spur gear, effectively preventing damage to the manual actuator during manual operation. All series of handwheels are side-mounted, which is very convenient for manual operation.
Product composition
Control unit
Handwheel
Motor
Cable entry
High starting torque/low inertia motor is used.
After starting, the torque can quickly reach the peak value. Built-in thermal protection and accurate temperature detection device prevent the motor from burning and ensure that the motor can maximize its efficiency.
Integrated unit
Standard settings include open/close/stop buttons and open/error/close indicator lights, monitoring execution device, local/remote control selection button, reverse phase power supply monitor, photoelectric coupler, etc. This unit is mainly used in occasions where local control is achieved using remote control circuits.
Operation unit
LCD display screen can be selected.
Terminal unit
It is an independent terminal block structure and adopts O-type gasket and V-type gasket double sealing structure, wide wiring space, and all terminals can be easily wired on site.
Switch unit
Including limit switch, torque switch, position indicator Limit switch Driven by a counting gear, it can ensure high reliability at any predetermined position. This type of limit switch is easy to set and can be tightened with a screwdriver after setting.
Torque switch
When the output torque on the output shaft of the electric actuator is greater than the set value, the torque switch automatically turns off the motor. The preset value of torque can be set at the time of shipment or by resetting the scale value on site.
Position indicator
The indication angle is wide, the linearity is good, and the dynamic information and variables of valves and electric actuators are accurately indicated in percentage.
Thrust unit
The thrust unit consists of a thrust bearing and two bushings. The threaded bushing is used for multi-turn valves, and the keyed bushing on the inner wall is used for part turn valves. The bushing is a detachable structure for easy installation.
Handwheel
The handwheel of all series of electric actuators is side-mounted for manual operation.
Handwheel shaft
The handwheel shaft is meshed with the worm through a spur gear to prevent damage to the manual parts during manual operation. There are two gears to choose from to facilitate customers' needs for different torques and speeds.
Switching lever
The switching lever can easily switch the operation from electric to manual while the motor is running. The standard supply is automatic switching. (Manual switching can be specially supplied)
