Mine Tunnel Air Door
Automatic interlocking, preventing blockage and ensuring smooth operation
Equipped with a dual-door interlocking linkage system, it can achieve the opening and closing of two sets of air doors simultaneously, eliminating the ventilation short circuit caused by simultaneous opening.
At the same time, it supports automatic switching based on personnel and mine car sensing, with a response time of ≤ 1.5 seconds, solving the problems of the cumbersome manual operation of air door opening and closing and the potential traffic congestion caused by it.
Sealed sealing, energy conservation and consumption reduction
The Mine Tunnel Air Door is equipped with rubber sealing strips and a mechanical compression structure. Its sealing performance has been improved by over 65% compared to traditional air doors, effectively reducing the wind leakage rate in the tunnel, lowering the energy consumption of the ventilation fan, and meeting the core requirements for long-distance ventilation and energy-saving control in overseas mines.
Explosion-proof and impact-resistant, with long-lasting stable operation
Using high-strength steel plates and anti-corrosion coatings, it has passed the explosion-proof certification of overseas mines. It can withstand collisions from mine vehicles and corrosion caused by high humidity and high sulfur in the underground environment.
The reinforced door frame design has strong anti-deformation capability, and its service life is approximately three times longer than that of traditional wind doors, making it suitable for harsh underground working conditions.
Visual control, convenient operation and maintenance
The Mine Tunnel Air Door is equipped with a remote status monitoring module, which can provide real-time feedback on the opening and closing status of the air door and its sealing performance. It also supports remote fault alarms and debugging. The core components are designed in a modular manner, allowing ordinary maintenance personnel to complete daily maintenance after training, thereby reducing the operational barriers for overseas maintenance.
Core value is prominent
