Intelligent electric actuator with the application of pneumatic actuators

it can be finished through the display and field control panel button switch, all parameter and debugging. Non-contact sensor output shaft position - - Location or run. In addition to debug, do not need any other tools. The graphical user interface provides diagnosis and maintenance information. The user's special setup can be external storage or restored within the actuator.
a lot of pipe device has all kinds of pneumatic valve adjustment. Settlement of shanxi aluminum plant section front-rear pipe pneumatic pneumatic valve installed on several machines, in order to control the production process of alumina. Due to the air quality is poor and backward wait for a reason, there are different levels of regulation, some even non-existing, seriously affects the control of the material. In order to reverse this advantage, with the one on the alkali liquor supply pipe MOE type intelligent electric actuator. Running for two months, excellent performance, get the site operating personnel.
the usage of the original pneumatic regulating pneumatic valve
the defects of pneumatic pneumatic valve mainly include: temporary production running applications. It is very inconvenient to repair
, air quality is poor: oil, water and other impurities in the compressed air. And the pressure of the compressed air is not stable, adjust the no fault or failure to appear pneumatic pneumatic valve, adjust the quality drops greatly.
the moment balance is destroyed, the actuator is not action: this is due to the use of pneumatic actuator torque is too big, too hard. Thus often appear pneumatic pneumatic valve open closed off to open up.
no replacement parts.
when there is a failure, such as pneumatic pneumatic valve failure maintenance personnel and labor intensity of operators: most of pneumatic pneumatic valve installed in more than ten meters high. Maintenance personnel need to climb to the pipeline maintenance. If pneumatic pneumatic valve failure, when need to be closed or open the pneumatic pneumatic valve, operators also need more than a dozen meters platform, operated by the handwheel.
MOE application of intelligent electric actuator
device a OntracMOE type switch type intelligent electric actuator. Considering the lye pipe pneumatic valve adjustment only, the effect was cut off.
。 The structure and principle of the intelligent electric actuator
as shown. Intelligent electric actuator by microprocessor, the operation panel, communication interface, location, and generator and the corresponding mechanical parts, etc.
output multi-turn movement way. Reduction gear is a three-phase motor self-locking type worm gear and worm, intelligent electric actuator is designed to open and close operation mode. Due to the electrical parts instead of the application of local mechanical unit, so less transmission components, and more powerful, higher reliability.
the middle speed reducer MOE can output degree Angle trip ( Moment of Nm and straight trip ( ~ kN can drive the damper baffle, rotating pneumatic valve and straight travel pneumatic valves. Cut off the output torque and speed can be set in a program.

。 Intelligent electric actuator MOE properties
Germany Hartmann& Braum company a new generation of products, choose the intelligent electric actuator MOE ZhiNengDuo rotary electric actuator for switch mode. Its characteristic is:
intelligent electronic integration, far infrared receiving window provide cover setting and debugging.
to realize stepless speed regulation. Motor adopts frequency conversion technology.
three-phase motor has been monitored, powerful monitoring functions: operation. As long as there is a phase occurs when power supply drop a fault signal and close the motor. And the fault phenomenon, as long as a super torque motor is shut down.
reset the order to start the executor. The intelligent electric motor actuators to record a super temperature, motor start/stop cycles, recently h switch frequency, diagnosis function: according to the details of the rapid diagnosis of fault information. Also can alarm the operating environment, according to the last time the maintenance of pneumatic valve, record positioning and cut off many times, record the average torque when debugging, etc.
/ ~ mA analog output, feedback or fieldbus transmission.
debugging is simple, maintenance is convenient.
to position quickly, variable speed positioning: in order to prevent the impact. Actuator speed will slow down so that I can smooth operating pneumatic valve and actuator.
。 Intelligent electric actuator MOE communication
and configuring RS communication interface, can be realized through the display and keyboard MOE the man-machine dialogue. Can choose practice control, also can choose Fieldbu can provide / ~ mA position feedback signal. I currently use the dashboard display and control, but the table in the DCS system, giving full play to the advantages of its communications, to prevent duplication of investment.
