This device is based on our current mine situation, refer to the characteristics of self-rescuer air pressure at home and abroad, through theoretical research, architectural innovation and research and development of a new type of isolated gas Hu suction guards, each of 4-8 people to use, when an accident or a self-help devices of harmful gases when the staff can not properly absorb Hu, appeared set for Escaping the mine, mine is an ideal air pressure self-help devices, which is characterized as follows: 1, made of stainless steel cabinet, trouble-free magnetic locks, beautiful and durable; 2, hydraulic hose φ25 quick plug, easy to install, use and reliable; 3, the internal use of stainless steel, brass connection, safe and reliable; 4, using a specially designed high efficiency water filter, a single pressure regulating device, wide voltage range, high flow range, the air filter water, impurities, but also reduce the noise, the air clean and hygienic through, so staff Hu suck comfort; 5, using a one-way section Hu suction valve with external harmful gases can not enter; Hu, a professor with the mouthpiece, Henan Polytechnic University according to the characteristics of the mine specially designed oral appliance is installed on a one-way valve, the gas can only be discharged out from the mouth with outside air can not and ensure the safety of miners, and does not affect the line of sight, personnel movable within a certain range. 6, according to user needs, design a variety of installation methods, and a number of Hu suction. Technical parameters: the name of the standard system air pressure adjustment 0.3-0.7MPa Hu suction pressure range of 0.05-0.1 MPa Hu inhaler gas volume range 30-55 L / noise <85dB (A) Operation Manual min output pressure gauge shows Self-priming protective mask method Dimensions (700 ~ 800) × 350 × 140 is mainly used for air pressure, self-help devices have coal and gas outburst in coal mine disaster protection. When the coal and gas outburst or a prominent warning, staff can enter the self-help within the device nearby hedge. The device is simple, fast, and reliable. Escaping personnel in the use of air pressure, self-help devices, comfortable, non-stinging and oppressive. Parameters: 1, stainless steel box, plug-in stainless steel locks; 2, hydraulic hose quick connect plug, easy to install, use and reliable; 3, the internal use of stainless steel, brass connection, safe and reliable; 4, using no more than 4 m toxic, flame retardant, high pressure masks even trachea; 5, breathing masks medical oxygen masks, light have health permits; 6, built six groups, for six people simultaneously.
