Compressed oxygen Self-rescuer product introduction
The isolated compressed oxygen self-rescuer is a recyclable rescue product carried by miners and rescue team members that meets national standards. It has a reasonable structure, reliable performance, and is easy to use. It is used when people are escaping or waiting for rescue in various toxic, harmful gases and hypoxic environments. It is an isolated self-rescuer that can be recycled.
Maintenance and maintenance
,
Self-rescuers should be checked frequently. Generally, oxygen cylinder pressure, positive and negative pressure air tightness, exhaust pressure, quantitative oxygen supply and other indicators should be checked every six months. If any gas leakage is found, If the pressure of the bottle drops, fill it with oxygen immediately (the oxygen used to fill the self-rescuer should comply with the standard requirements. If it is found that it does not meet the specified indicators, it must be adjusted and repaired. If you encounter severe impact while carrying it, and if you have doubts about the performance of the instrument, Also check the above indicators and make repairs. Replace the carbon dioxide absorbent every six months.
,
Replace the carbon dioxide absorbent that meets the standard after each use (the absorption rate should not be lower than the other performance The indicators should comply with relevant regulations. When filling, vibrate while filling. The charge amount is about grams
. After filling, close the bottom cover

How to inflate the gas cylinder Unscrew the pressure cap, pull out the cylinder, and remove the pressure reducing valve to fill the oxygen cylinder with oxygen. The pressure should be above. After filling with oxygen and charging, assemble. During assembly, great attention must be paid to installing the When exhaling, be careful not to twist the hose, otherwise it will increase the exhalation resistance. Severe twisting will block the exhalation air path. Tighten the pressure reducing valve on the handwheel switch, and completely hang the rubber ring on the air bag on the pressure reducer. In the annular groove.
,
Before installing the cover, hold the mouthpiece and make the air bag go around the pressure gauge counterclockwise. The opening of the mouthpiece must face upward. Please note that the air supply pressure plate must be placed upright and not to be pressed. Press the cap on. This is the best assembly position. Gently buckle the upper cover to restore the instrument to its intact condition. (Be careful not to clip the airbag when buckling the lid.)
,
Once the self-rescuer Before use, the airbag mouth piece should be cleaned, disinfected and dried after each use.
, < br/>After assembly, the respiratory system must be airtightly calibrated. The change in the internal water column does not exceed the standard under positive or negative pressure. Close the exhaust valve when calibrating the airtightness.
,
Storage When operating, the self-rescuer should be protected from direct sunlight and should not be mixed with grease. The storage environment should be dry, free of corrosive gases, and the temperature should be above ℃. The custodians and operators of oxygen cylinders must strictly abide by relevant rules and regulations.
