ZYJ type mine air pressure water supply self-rescue device

Overview of ZYJ type mine pressurized air supply self-help device

ZYJ self-help type mine air pressure water supply device is according to our country coal mine dust, gas, and the actual situation of co2 outburst mines, combined with the scene of the rescue breathing practical experience, the innovation and development of a new type of pressurized air supply self-help device, because the devices have a constant supplies, constant water supply, manual steady pressure regulating device, so it is very popular with the ore party a breathing protector.

The device is mainly used for underground rescue and protection of coal mine with coal and gas outburst. It is installed in the coal mine under the chamber or working face of the machine tunnel air tunnel head of the appropriate location or more mobile people, as well as the head of the chute, underground car yard, transport and return air tunnel, various stations and other places. In case of accidents or the occurrence of harmful gases in the underground coal mine that make the workers unable to breathe normally, the workers can enter the nearest self-help device to avoid disaster, put on breathing apparatus and wait for rescue.

The fresh air and water conveyed by the self-rescue device enable the disaster avoidance personnel to achieve the purpose of avoiding disaster safely and stabilizing working emotions. Under normal circumstances, the number of self-rescue devices installed underground shall not be less than one third of the total personnel underground.

ZYJ type mine air pressure water supply self-rescue device has the functions of decompression, noise elimination, flow adjustment and oil and water filtration on air pressure gas and water supply device. It is easy to install, beautiful and generous, long service life, low noise and so on. ZYJ type pressurized air water supply self-help device also has the advantages of not affecting the line of sight of the user, the user can work and move within a certain range, and can sit quietly or sleep while waiting.

Structure and working principle of ZYJ type mine pressurized air supply self-rescue device

ZYJ type mine pressurized air supply self-rescue device is a new product integrated with isolated gas breathing device and drainage device. This device has six groups in one box and can be used by six people at the same time to achieve the effect of taking care of each other.

ZYJ type mine pressure air supply self-rescue device is composed of box, mounting plate, intake pipe, intake pipe, water purification filter, door lock, breathing apparatus (multiple groups), drainage device, etc. The box, installation plate, intake pipe and intake pipe are made of stainless steel.

ZYJ self-help type mine air pressure water supply device in the gas supply system USES light breathing mask directly in mouth to breathe, and through the spring hose, and water supply unit directly through the spring tube flow into his mouth, will not affect the use of personnel, spring hose can freely adjustable, can use personnel within the scope of the spring hose scalable free activities.

ZYJ type mine pressure air self-rescue device is generally supplied by mine pressure air pipe, and water supply device is generally supplied by pump station.

Operation of ZYJ type mine pressure air water supply self-rescue device

(1) Air path operation

1. Press the door lock switch to open the box door.

2. Take the light breathing mask and put it on the mouth, open the corresponding control valve, and use the control valve to adjust the air supply quantity according to needs.

3. When the water in the filter cylinder exceeds the upper limit of water level, drainage shall be carried out. Drainage method: Push the drain column upward and the water will be discharged immediately. After drainage is completed, release the drain column and restore it to the end of drainage.

4. Adjust the air supply pressure through the pressure reducing filter. Adjustment method: pull up the pressure regulating knob, clockwise rotation, pressure rise, counterclockwise rotation, pressure drop, pressure value is displayed by the pressure gauge, 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.

(2) Operation of water supply installations

1. Open the box cover and take out the spring hose.

2. Put the spring hose into the mouth and then open the regulating valve.

3, slowly adjust the valve to adjust the size of the water pressure.

4. Close the regulating valve after use.

ZYJ type mine pressure air water supply self-rescue device -- Overhaul and maintenance

1. Regularly (every day) check whether the respirators and drainage devices of each group in the box are placed in order and shall not be in disorder.

2. Check whether there is air leakage or water leakage in each air channel, water channel and connecting pipe fittings. If there is any, seal treatment should be carried out.

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