Rotary damper electric intelligent modulating high torque actuator SD A+RS160

Classification and use of SD products.SD non-intrusive intelligent electric actuator is the execution unit in industrial automation instrument, it receives from the regulator, PLC, DCS control signal from the computer, such as the completion of automatic adjustment, is indispensable to automatic control system for main equipment. It is widely used in power station, metallurgy, petroleum, chemical mine, light industry, pharmacy, gas power, building materials, transportation and city subway, water supply, sewage treatment and other industries.Electric actuators are classified according to output.Quarter turn actuator.Also known as part of the return receipt actuators, general rotation range of 0-90& 176, the output torque in Nm. Mainly used for: butterfly valve, ball valve, shutter type valve, damper, baffle and plug valve.Linear-turn actuator.The output is indicated by N, and the output is a linear displacement.Mainly used for single, double seat control valve, sleeve valve, gate valve, etc.Multi-turn actuator.Output torque in Nm, more than 360& 176rotation. It is mainly used for gate valve, globe valve, slide valve, high temperature and high pressure regulating valve, etc.Electric actuators are classified according to control feature.Integration modulating electric actuator.Analog control signals can be received 4-20ma, 0-10ma, 1-5v, etc. The output Angle is proportional to the input analog signal, and the actuator itself is closed loop and realizes automatic adjustment.Integral switch actuator.Receiving signal switch. Including remote control type and switch type.Linear actuators.It can be divided into modbus, profibus, etc.SD product featuresSD series electric actuator is used in the structural design of composite structures, the generalization, standardization, seriation products in parts into consideration is more considerate, makes the product by machinery, motor, control circuit, combined to form a variety of different series and specifications, users in the use and maintenance of the greatly reduced the number of varieties of spare parts needed.The basic base of the product reducer adopts the high strength aluminum alloy, the mechanical structure design is concise and compact, the reliability is high, the volume is small, the weight is lightMultiple connections can be installed in any position and direction.Configuration characteristics of electric actuators.Local native operation function. The product is equipped with a magnetic switch without an interconnecting shaft, which can be switched on and off by switch and turn on/off to the actuator.Overtorque protection function. Actuator is equipped with a torque protection measurement, the role of the torque can be accurately measured valve, when more than set range, located within a actuator torque switch sends out the signal to the control circuit, the circuit has a memory function, will lock actuator running in the direction of the output signal, motor stalling, so as to protect the valve and actuator drive and motor. When the mechanical torque failure is eliminated, the actuator is switched off or the signal is reversed in an instant to return to normal work.Special servo motor. The single-phase or bi-directional motor used by the actuator has a special motor with high starting torque, low rotary inertia, small starting current, and good servo characteristics. The motor is allowed to start frequently and is allowed to start 1200 times per hour.Thermal protection of motor. Actuator motor fittings are equipped with thermal protection switch, the switch is connected to the control circuit, abnormal when the motor overheating, internal temperature over 130& 176, thermal switch automatically disconnect, at the same time, it will control power circuit of the motor, so as to protect the motor and actuator, when the motor cooling switch back on, circuit return to work.
