Model selection, Installation and Commissioning of Electric Actuators
Model selection, installation and commissioning of electric actuators are crucial steps to ensure that device can operate normally and deliver its intended performance. Below are detailed recommendations covering these three aspects:
Select appropriate torque according to the characteristics of controlled objects. Different objects have different torque requirements, for example, valve control requires higher electric torque, while window and door control doesn’t need such a high torque. Therefore, T.crystal offers electric actuators with a wide range of torque options, including 10nm torque, 20nm torque, 30nm torque, 50nm torque, 80nm torque, 110nm torque, 200nm torque, 400nm torque, 1000nm torque and 2000nm torque, for your selection. Our diverse torque range is designed to meet various industrial control scenarios. Each torque grade is precisely calibrated to ensure stable driving force, reliable operation and long service life. Customers can flexibly match the corresponding torque actuator based on their actual working pressure, pipe diameter and application environment, effectively improving control accuracy and reducing energy consumption.
Ensure the voltage and frequency based on the actual working environment and application requirements. Electric actuator supports a wide range of voltage and frequency options, yet different specifications will directly affect key performance indicators such as torque output and rotational speed.
Electric actuators are classified into on off actuator and modulating actuator. On/off type only has two working states: open and closed. So this type cannot control the intermediate positions, while modulating type can adjust the valve to any positions. Therefore, during the model selection, users need to clarify the specific requirement of the controlled objects and choose the corresponding working modes.
Rotation speed is another important parameter for electric actuator operation, usually expressed in RPM (Rotation count per minute). Meanwhile, an appropriate accuracy level should be selected according to the features and control requirements of controlled objects.
In addition, the types of electric actuators also should be considered, such as rotary actuator, multi-turn actuator and linear actuators, which are adapt to different control commands.
Make sure that the model, specification and design are aligned with the corresponding electric actuators, meanwhile, users need to check whether the appearance is damaged or components are missing.
During the installation, guarantee that the electric actuator axis is aligned with the valve axis, the connection should be fastened without looseness.
At the same time, pay attention to the working environment of electric actuators and avoid using them in the high-temperature, humid and highly corrosive environments.
After installation, electric actuators need to operate without load, and then user should check whether the actuator operates normally.
Connect the electric actuator power wire and turn on the power switch. Select the function switch on the control panel and set the electric actuator to the relevant working mode.
Based on the actual requirements, adjust the actuator travel, speed and other parameters to achieve the expected working states. During the adjustment, user needs to observe the operating status of electric actuators and shut down for immediate inspection if anything abnormal happens.
After finishing parameter adjustment, user needs to test the accuracy and stability of electric actuators to ensure they can meet the control requirements.
Upon completion of the above steps, the model selection, installation and commissioning of electric actuators are basically finished. In the practical application, appropriate adjustments and optimizations should be made according to the specific service environment and control requirements. Meanwhile, regular maintenance and protection is necessary to ensure their long-term stable operation.
