ZH30 type chemical oxygen self Products ZH30 chemical oxygen self mainly by the high-pressure system, respiratory system and CO2 filtration system consists of: high-pressure system: oxygen bottles, oxygen cylinder switches, pressure reducer and pressure gauges. Respiratory system: an oral appliance, nose clip, breathing hoses, air bags, exhaust valve and breathing valve. Filtration system: clean the tank and into the quantitative standard within the CO2 absorber components. Usually all system devices are housed in shelters and lower shell, through the observation window on the cover can be clearly seen pressure oxygen bottles, there are belt loops and straps on the lower shell, the user can carry on a belt or across the miners shoulder. Uses: 1, ZH30 chemical oxygen self is the body's respiratory system protection devices, mainly used in coal mining operations underground when the mine disaster in case of an accident, resulting in anoxic environments or with high concentrations of toxic gases endanger the lives and safety Miners can wear this timely rescuer achieve respiratory protection, and evacuated from the disaster area to escape the same time the self-control also apply to: (1) as an auxiliary respirator mine rescue teams; (2) as the petroleum, chemical industry and laboratory and other toxic spill escape; (3) escape various tunneling and underground engineering hypoxia and toxic environment; (4) other underground mine self protection. Environment: (1) environmental restrictions against the use of asphyxiating gases and oxygen concentrations; (2) the ambient temperature 0 ~ 40 ℃ characteristics and requirements: (1) early starter in oxygen using chlorate oxygen candle, Health oxygen fast, safe and reliable. (2) KO 2 flaky oxygen generating agent, oxygen generating sufficient uniformity, less dust, stable performance, low suction temperature, low breathing resistance. (3) the use of glass fiber composite mat dust resistance, dust resistance is good, comfortable to wear.
