How should the sealing performance of the sealing baffle doors in mechanical equipment be designed?

Thread Content

The design of the baffle door enables it to withstand the temperature and pressure of flue gases under various operating conditions, without any deformation or leakage. The design of the shutter doors and drive mechanisms is capable of withstanding the corrosion that may occur from the working medium under all operating conditions. The baffle adopts a plug-in plate design and features 100% airtightness. The baffle features a quick-opening function, with the time required to open it from fully closed to fully open being ≤45 seconds. The flue gas dampers can operate under maximum pressure differences, and they close tightly without deformation or sticking. Moreover, the dampers must fit properly with the locking mechanisms when in the fully open and fully closed positions. The structural design and arrangement of the flue damper doors should minimize dust accumulation within them. All dampers/actuators of electric dampers are equipped with reliable mechanical limit switches for full open and full closed positions (unaffected by power supply), with contact ratings of at least 220VAC, 3A. The speed of the electric baffle door actuator meets the operational requirements of power plant boilers and exhaust fans.
