Design and Application of a New Type of Remote Control Balancing Damper
Aiming at the existing problems of difficuly in operating dampers,mine pressure deformation,safety risks and so on in Tunlan Mine,a new type of remote control balancing damper is designed.The balance damper adopts anti deformation,three-dimensional adjustable,on-site intelligent control,and remote unlocking short-circuit smoke exhaust technology measures.Finite element analysis method is used to simulate the compression of the balance damper.High strength SPCC cold pressed steel plate is selected,and a multi-layer composite structure is designed to improve the strength and lightweight of the damper;By using a three-dimensional adjustable rotating hinge and adjustable rod mechanism,the ability of the air door to adapt to tunnel deformation is improved,equipped with an intelligent control system to achieve real-time monitoring and automatic adjustment.The new balanced air door performs well under mining pressure and wind pressure conditions,and the door leaf and hinge have not failed or undergone large displacement deformation during long-term use.The door frame has anti mining pressure performance.The air damper opens and closes normally under a wind pressure of 1676 Pa,meeting the demand for air regulation.The new balanced air door can improve the stability and safety of the ventilation system,and is suitable for environments with large cross-sections and large pressure differentials in tunnels.
