JiangsuBell Valve Control Co., Ltd. specializes in the production of Siemens electric actuators and Rotork electric actuators in GermanyPSElectric actuator, compact electric actuator,LQSeries electric actuators,DKZDirect stroke electric actuator,DKJAngular stroke electric actuator,DQWPartial rotary electric actuator,DZWMulti turn electric actuator,3810The series of electronic electric actuators, electric valve controllers, electric gate valves, electric globe valves, electric butterfly valves, electric ball valves, electric regulating valves, check valves, solenoid valves, and shut-off valves are widely used in automation industries such as power, steel mills, petroleum, metallurgy, chemical, building, and water supply and drainage engineering.
DKZProduct Introduction of Electronic Straight stroke Electric actuators
DKZThe linear electric actuator can not only work withⅢType control unit instruments can be used in conjunction with newly developed onesSThe matching of control unit instruments makes the entire control system more stable, reliable, and has better performance and more functions. Therefore, users can adjust the system accordinglyzKzThe requirement for a type of electric actuator is to automatically select control unit instruments and combine them into a control unit system.
DKZMethod for representing the model of electronic linear electric actuators
DKZWorking principle of electronic linear electric actuator
When the input signalIenter1=4mA. DCposition feedbackIagainst=4mA. DCThe time amplifier is equipped with an output, the servo motor stops rotating, and the output shaft is rapidly set at the zero position of the stroke. When there is an input signal at the input end（Ienter1>4mA-DCAnd the polarity is opposite to that of the position feedback current. This input signal is compared with the position feedback current of the system itself in the pre magnetic amplifier of the servo amplifier for a comprehensive comparison of magnetic potential. Due to the opposite polarity of these two signals. If they are not equal, there will be an error magnetic potential, which will enable the servo amplifier to have sufficient output power to drive the servo motor. Rotate the output shaft of the actuator in the direction of reducing this error magnetic potential until the position feedback signal is equal to the input signal, at which point the output shaft stabilizes at the stroke position corresponding to the input signal.
Due to the double bar braking structure adopted by the two-phase servo motor, and the fact that the input signal and position feedback signal reach normal levels, the servo amplifier can send a dynamic braking signal to immediately stop the rotation of the two-phase servo motor. This can prove that the servo motor can quickly stop after power failure, thereby improving the system stability of the electric actuator, limiting the inertia coasting of the output shaft of the electric actuator, and overcoming the influence of load reaction.
DKZInstallation and wiring of electronic linear electric actuator
The servo amplifier should be installed at an ambient temperature of0~50℃Relative temperature≤85%In an environment without corrosive gases, the wall mounted structure can be vertically installed on a metal frame or column.
The actuator should be installed at an ambient temperature of-25~+70℃Relative humidity≤95%In an environment without corrosive gases, in general, the actuator is installed on the valve body of the regulating valve and fastened with screws, but it can also be installed on other regulating mechanisms. During installation, consideration should be given to the convenience of manual operation, maintenance, and disassembly. During installation, it is necessary to avoid any loose gaps at all joints. The limit block is used for limiting and cannot be loosened or disassembled casually.
Bell solemnly promises that all products have undergone strict quality control operations and performance tests before leaving the factory, and are guaranteed for one year under normal use from today. However, disasters beyond human control, external damage, and unauthorized dismantling without the consent of our company are not covered by the warranty.
