ZYJ(A) type mine pressure air self-rescue device

Overview of ZYJ(A) type mine pressure air self-rescue device

ZYJ mine air pressure type (A) save your device is mainly used in the coal mine disaster protection, when the coal mine accident or harmful gases staff cannot breathe normally, staff can enter to the nearest place to avoid disaster self-help device, through the self-help device conveying fresh air, make the personnel to avoid disaster can breathe easy for A long time to reach the purpose of safety, stability, avoid disaster work mood, usually underground installation of self-help device number shall not be less than A third of the total.

ZYJ(A) type mine pressure air self-rescue device has the functions of decompression, noise elimination, flow adjustment, oil and water filtration, etc. It is easy to install, beautiful and elegant, long service life, low noise, fresh and hygienic air, etc. ZYJ type pressure wind self-help device also has the view will not affect the use of personnel, use of personnel can work within a certain range, the advantages of can sit or sleep in waiting, solved the old wind pressure self-rescuer in use process, the workers into ram bag keep out line of sight, can't understand the change of the surrounding environment, causing anxiety, affect the self-help and so on.

Structure and working principle of ZYJ(A) type mine pressure air self-rescue device

ZYJ(A) type mine pressure air self-rescue device is A new type of isolated gas respiration protection device. This device has six groups in A box and can be used by six people at the same time to achieve the effect of taking care of each other.

ZYJ(A) type mine pressure air self-rescue device is composed of box, mounting plate, intake pipe, door lock, breathing apparatus (multiple groups), etc. The box, mounting plate and intake pipe are made of stainless steel. The respirator is installed in the box. The respirator is composed of a regulating valve, a decompression filter valve, a spring hose, a light breathing mask, etc. Decompression filter valve filter impurities, water and oil in the air, reduce pressure wind noise, can accurately adjust and control the air supply pressure, so that workers breathing without obstruction, smooth and comfortable.

ZYJ(A) type mine pressure air self-help device USES A light breathing mask to breathe directly on the mouth, and is connected through A spring hose, which does not affect the sight line of the user. The spring hose is freely telescopic, and the user can move freely within the telescopic range of the spring hose.

ZYJ(A) type mine pressure air self-help device is generally supplied by mine pressure air duct.

Operation of ZYJ(A) type mine pressure air rescue device

1, press the door lock switch, open the box is closed.

2. Pick up the light breathing mask () and put it on the mouth, open the corresponding control valve (), and adjust the air supply according to the needs of the control valve.

3. When the water in the filter cylinder -2 exceeds the upper limit of water level, drainage shall be carried out. Drainage method: push up the drainage column -1, and the water will be discharged immediately. After drainage is completed, release the drainage column and reset it, and the drainage is finished.

4, air supply pressure adjustment, through the pressure reducing filter adjustment air supply pressure. Adjust method: pull up the pressure regulating knob -4, rotate clockwise, the pressure rises, rotate counterclockwise, the pressure drops, the pressure value is shown in the pressure gauge -3, adjust to the required pressure, press down the pressure regulating knob to the locked state.

5. After use, close the regulating valve, put the respirators of each group into the box in an orderly manner, and close the box door.

Repair and maintenance of ZYJ(A) type mine pressure air self-rescue device

1. Regularly (every day) check whether the respirators of each group in the cabinet are placed in an orderly manner, without any disorder.

2. Check whether there is air leakage in each air line and connecting pipe fittings. If there is, seal it.

3. Check whether the connection fasteners of the installation are fastened. If they are loose, they must be firmly fastened.
