Air pressure, wind pressure self-help device self-rescuer

working principle

Air pressure self-help devices (also called self-rescuer air pressure), mainly for having a coal and gas outburst coal mine disaster protection. When the coal and gas outburst or highlight omen, staff can enter the self-help device Escaping the nearest General The number of self-help devices installed downhole case not less than one-third full of downhole.

Air pressure self-help device uses light absorption mask Hu conducted directly in the mouth with Hu suction, also with a stable pressure regulator, manual flow regulation, three silencers, filters, drainage, dust of six functions, but also within the scope of the spring tube freedom of movement conveying fresh air through the device, so that disaster prevention staff can be a long suction Hu easy reach safety disaster prevention, emotional stability purpose. It's commonly used mine air pressure gas pipeline, to reduce wind pressure gas pressure, muffler, flow control, water filtering and other functions, to provide fresh air for the staff. This means there is easy to install, nice, long life, low noise, clean air and health, does not affect the line of sight, people in certain Advantages activities within the scope of work, one ideal ZYJ mine air pressure self-help device.

The basic parameters of air pressure self-help device :
