　　Made through the sincere efforts of all employeesBGP -200 High expansion foam fire extinguishing device for coal mineWe doBGP -200 High expansion foam fire extinguishing device for coal mineCollaborative progress, pioneering spirit, and making good decisions according to your requirementsHigh expansion foaming machine.

　　BGP -200High expansion foam fire extinguishing device for coal mineIntroduction:

　　High expansion foaming machineUsed to extinguish large-scale fires in coal mine tunnels and limited ground and underground spaces, including coal mine, wood, oil, rubber and other material fires. Because the driving air pressure is high, it can be operated in the roadway far away from the fire disaster area. The foam can be pushed about 300 meters in the roadway, which is easy to recover after the fire and can shorten the fire extinguishing time.

　　BGP-200 high expansion foam fire extinguishing device is newly equipped with "foam driving pressure gauge" to observe whether foam emission is normal at any time. The 380V/660V fan motor and water pump motor can be used with different voltages underground, which is another breakthrough in the field of high foam technology equipment.

　　BGP -200High expansion foam fire extinguishing device for coal mineWorking Principle:

　　High expansion foaming machineThe fire extinguishing mechanism of is mainly cooling and suffocation, that is, to form a continuous foam layer on the surface of the burning combustor, to cool the surface of the combustor through the foam itself and the separated mixture, and to isolate the combustor from oxygen through the covering effect of the foam layer to extinguish the fire. The specific content is as follows

　　1. The foam layer seals the surface of the combustion material, which can block the thermal radiation of the flame on the combustion material, prevent the evaporation or thermal decomposition of the combustion material, and make it difficult for combustible gases to enter the combustion zone.

　　2. The foam covering layer formed by the extinguishing foam on the surface of the combustor can isolate the surface of the combustor from the air.

　　3. The liquid released from foam can cool the surface.

　　4. The water vapor generated by the evaporation of foam heated has the effect of diluting the oxygen concentration in the combustion zone.

　　BGP -200High expansion foam fire extinguishing device for coal mineTechnical features:

　　1. Fast and powerful fire extinguishing speed;

　　2. The device is flexible in movement and easy to operate;

　　3. It can safely carry out rescue and extinguish foam in a place far away from the fire site. The distance of advance in the roadway can reach about 300 meters;

　　4. Low cost, non corrosive, and easy to restore work after extinguishing a fire.

　　BGP -200High expansion foam fire extinguishing device for coal mineOperating procedure:

　　1. Choose a suitable foaming location: a safe location that is convenient to use water and power sources, and close to the fire area.

　　2. Quickly connect the foam mesh covers of the two fans and fasten the screws to form the entire machine.

　　3. Put the submersible pump in the pool or other containers containing water, straighten the hose of the submersible pump, do not fold or twist it, connect it to the hose connector of the mesh cover, prepare the foam liquid suction pipe, and insert it into the foam bucket.

　　4BGP -200 High expansion foam fire extinguishing device for coal mineConnect the power supply lines of the submersible pump and two fans. One person operates the power switch of the submersible pump, and one person operates the power switches of the first and second fans.

　　5High expansion foaming machineConnect the main power supply (operated by 2 people), operated by 1 person, and supervised by 1 person. After the monitoring personnel see that the installation and connection operation is completed, they wait for the commander to issue the power transmission command before sending the power.

　　6. All positions have been connected and are on standby in place. After the commander orders the power supply, immediately debug the submersible pump and the first and second fans to ensure normal operation.

　　7. WhenBGP -200 High expansion foam fire extinguishing device for coal mineScheduling is normal. According to the commander's orders, first supply water and medicine, then turn on the first fan, confirm foaming, and then turn on the second fan to increase the air supply for foaming.

　　8. The operation of high expansion foam fire extinguisher is required to be completed within 15 minutes.

　　9. When stopping foaming, the air should be stopped first and then the water should be stopped.
