What is an electric damper for a ventilator?
Release time:
Nov 19,2020
The electric damper for ventilators is an automatic control device designed specifically to meet the increasingly high demands for mechanical automation in the coal industry. This device features both electric and local operation modes, enabling remote control of the damper. It also includes overtravel protection and a function for switching between electric and manual operation, significantly enhancing the equipment’s safety and reliability. Easy to install, commission, operate, and maintain, this device represents an ideal replacement for slide dampers used in ventilators.
For ventilators Electric damper It is an automatic control device for ventilation damper doors, specifically designed to meet the increasingly high demands for mechanical automation in the coal industry. The device features both electric and local operation modes, enabling remote control of the damper. It also features overtravel protection and electric-to-manual switching functionality, significantly enhancing the equipment’s performance. its safety and reliability. The device is easy to install, debug, operate, and maintain, making it an ideal replacement for plug dampers used in ventilators.
1. For ventilators Electric damper Conditions of use:
1. Power requirements: Single-phase AC power.
Voltage: 220V; Frequency: 50Hz
2. Environmental conditions
Temperature: -10 to 50℃; relative humidity: no more than 95%; atmospheric pressure: 86–106 kPa; the surrounding air contains no corrosive media.
II. For ventilators Electric damper Installation:
1. Connect the fan using the matching bolts. Electric damper Install the flanges and collector flanges, which are marked with the airflow direction, and tighten them securely. Note: All bolts must be fitted with flat washers and spring washers of the same specification. Seal the space between the two flanges using asbestos rope.
2. Set the transfer switch to the stop position.
3. The user shall complete the electrical connections of the electric damper device according to the accompanying drawings.
4. Set the transfer switch to the “open” position and observe whether the damper operates normally. After the damper rotates 90 degrees, check whether the electric actuator can automatically disconnect the power supply and whether the motor stops working.
6. After completing the previous step, set the transfer switch to the “close” position and observe whether the damper operates normally. Once the damper has rotated 90 degrees, check whether the actuator can automatically disconnect the power supply and whether the motor stops working.
7. After completing the above two steps, set the transfer switch to the stop position, disconnect the power supply, and the trial run is now complete.
Each time used Electric damper Afterward, the user needs to set the transfer switch to the stop position and disconnect the power supply to prevent the electric actuator from being damaged due to equipment failure or other reasons.
