The operation of the barrier door should be flexible, reliable, and convenient.Pneumatic damper doorUnless otherwise specified, electric air door dampers will be equipped with remote control and an operator for on-site manual operation, as well as a local damper position indicator for installation.
Each damper operation should be flexible, convenient, and reliable. The actuator of the electric damper door should be capable of both local and remote operation, with feedback of the damper door position and its open/close status entering the PLC control system.
Electric Sliding Gate、Pneumatic dampers doorThe actuator should be equipped with position locators at both ends, two-way rotation switches from Taizhou Blue Sky Machinery Co., Ltd., an emergency handwheel, and a mechanical interlock for maintenance. The protective grade of all local control devices and measuring equipment should be at least IP56, and capable of preventing dust entry.
Plate door actuator (electrical actuator)
The stainless steel baffle should be equipped with an electric actuator for remote control and on-site manual operation, with the smoke inlet and outlet baffle doors being of the switch type.
The electric actuator should adopt an integrated structure to meet the requirements of its working environment, such as temperature and humidity, with a minimum protection level of IEC standard IP55, including the motor and junction box. The operating frequency range of the electric actuator motor is within ±5% of the normal range, and the voltage range is +10% to -10% of the normal voltage. If the voltage drops to 85% of the normal value and both torque and axial pressure are normal, the motor of the actuator can still be started.
The actuator can be manually operated locally through a handwheel and an air-operated butterfly valve. A local position indicator is installed on the actuator, which can be clearly observed from the ground.
All actuators are equipped with a complete on-site assembly, featuring connection terminals or sockets connected to power and control cables. These connectors should be manufactured in accordance with IEC 309 or equivalent standards.
