Hydraulic automatic air door

miningHydraulic automatic air doorIt is a general term for ventilation equipment in coal mines, including infrared induction electro-hydraulic automatic waterproof and airtight doors, hydraulic self compound vertical shaft explosion-proof doors, electrically controlled hydraulic automatic pedestrian dampers, monorail hanging doors, etc. These series rely on hydraulic systems to provide power and achieve remote intelligent operation.

Like a coal mineHydraulic automatic air doorThe remote intelligent fully automatic self resetting explosion-proof door for the return air shaft, which is one of the series, can be controlled by pure electric motor or hydraulic station to provide power for the angle cylinder or hydraulic motor, achieving the functional requirements of one key reverse air and fully automatic reset of the explosion-proof cover. Compared to pure electric control, hydraulic control is more suitable for harsh environments such as wind and rain in wellheads.

Non coal mines such as iron ore and phosphate ore are used for mining purposes in mountainous areasHydraulic automatic air doorThe ratio is higher than that of coal mines, which is determined by their objective conditions. There is generally a stable gas source in the underground pipelines of coal mines, and using electrical dual control automatic dampers is more cost-effective. However, for non coal mines such as iron mines where the gas source is unstable, using electro-hydraulic automatic dampers is more practical.

Hydraulic automatic air doorOften equipped with mining infrared sensors or GUH3 mining intrinsic safety infrared induction switches, GFK25 mining intrinsic safety air door opening and closing status sensors and other electrical components, accurate collection of mining car, pedestrian traffic signals and underground air door operation status.
