Mining electric air door/self recovery shaft explosion-proof door

Mining electric dampers mainly include remote intelligent pure electric control automatic dampers for coal mines, hydraulic self resetting explosion-proof doors (explosion-proof covers) for vertical shafts, mining waterproof gates, and fully automatic control dampers for pedestrian traffic, which require power supply to operate automatically. The intelligence level of coal mine electric control automatic air door is higher than that of pure pneumatic balance air door.

One of the series of mine electric air doors, the self resetting explosion-proof door of the coal mine vertical air shaft, has gradually replaced the old explosion-proof cover of the vertical shaft. In order to save production costs, some mines have not replaced the overall fully automatic control explosion-proof cover of the vertical shaft, but have still made efforts to transform the original round cover type vertical shaft door into a remote intelligent automatic reset and one key reverse air system.

The remote fully automatic reset type vertical shaft explosion-proof door lifts the explosion-proof cover under the weight of the counterweight block during power outage and air stoppage at the wellhead, achieving natural ventilation underground; After the air pressure returns to normal, the door leaf will automatically reset under the action of the power actuator, and the opening and closing information of the self resetting explosion-proof door of the coal mine shaft will be transmitted to the management platform at any time.

The fully automatic self resetting explosion-proof door for mining is the highlight of the mining electric air door series. In addition, the coal mine electric air door produced by Jinan Dongshan manufacturer also includes hydraulic automatic waterproof gates, mining remote intelligent electric adjustment windows and other equipment.
