Wheeled long tube respirator chzk6 8 * 2 positive pressure long tube air respirato

  Wheeled long tube respirator chzk6 8 * 2 positive pressure long tube air respirator
CHZK6
8 * 2 long tube air respirator, positive pressure long tube air respirator, cart type long tube respirator, 2 gas cylinder long tube respirators
Scope of application:
CHZK6
8 * 2 positive pressure long tube air respirator is suitable for fire protection, petroleum, chemical industry, smelting, warehouse, aerospace industry, nuclear industry, waterworks, municipal engineering, underground engineering, hospital, epidemic prevention and other departments and relevant occasions
The operators can work freely within 60 ~ 90m away from the respirator through the medium pressure conduit
During use, the gas cylinders can be switched in turn, and the high-pressure gas cylinders can be replaced without interrupting the operation to realize continuous operation
The respirator can be used by two people at the same time

Working principle: ,
The high-pressure air in the gas cylinder is connected to the pressure reducer through the connector, and the reduced air enters the comprehensive hood through the medium pressure conduit and the quick connector to the supply valve to realize on-demand gas supply
The exhaled gas is discharged into the atmosphere by the exhaust valve on the full hood
When the pressure reducer fails and the output pressure increases, the safety valve will exhaust automatically
The respirators are equipped with residual pressure alarm function
When the pressure of the gas cylinder drops below 5
5mpa, an alarm will sound

usage method:
1
Before use, the gas cylinder shall be filled with air to the rated pressure
During inflation, a special connector shall be used to connect with the air compressor and operate according to relevant procedures

2
Before use, check the reliability, air tightness and output pressure of the pressure reducer of the gas supply system

(1) Check the output pressure of the pressure reducer: open the gas cylinder switch, the indication value of the high pressure gauge shall be close to the rated pressure value, and the indication value of the low pressure gauge shall be 0
75 & plusmn; 0
15MPa。
(2) Air tightness inspection: according to 4
2 1
After the operation, turn off the gas cylinder switch, and the indicated value of the high-pressure meter shall not drop more than 2MPa within 1min, and the indicated value of the low-pressure meter shall have no obvious change, indicating that the air tightness of the system is good

3
Wearing inspection: insert the quick connector of the supply valve into the quick socket, turn on the gas cylinder switch and press the manual button on the supply valve
At this time, the supply valve is closed
Put on the mask (the mask should be close to the face) and take a deep breath for 2-3 times
When inhaling, the indicated value of the low-pressure meter drops back
When exhaling, the supply valve stops supplying air and the breathing feels good
Then press the manual button on the supply valve, and then conduct the breathing test
Repeat it for 2-3 times
If the breathing is normal, you can enter the normal operation state

4
When the cylinder pressure drops to 2MPa, open the next cylinder switch in time to make the system work continuously
At this time, open the vent valve of the gas cylinder with insufficient pressure and replace it with a standby gas cylinder with sufficient pressure

5
After use, remove the lower cover at a safe place, close the cylinder valve, pull out the quick connector, and clean, disinfect and dry the cover and supply valve

6
Open the vent valve, remove the gas cylinder and fill it with air meeting the breathing standard to the rated pressure for standby

7
Clean and check whether all systems of the respirator are damaged, whether the air tightness is good, and whether the respiratory system is normal
In case of abnormality, repair it

At present, Taian Yucheng vehicle mounted long tube air respirator has four models: chzk6 8*4、CHZK6
8*2、CHZK9
0*4、CHZK9
0*2。 The product, also known as mobile air source, is a vehicle self-contained open positive pressure long tube air respirator
The respirator adopts a wide field of vision comprehensive mask, and the pressure in the mask is always greater than the atmospheric pressure of the surrounding environment
Therefore, it can obtain safe and reliable respiratory protection when equipped with the respirator for operation or rescue under severe environmental conditions such as hypoxia or toxic and harmful gas, thick smoke and dust
