Features: It can be observed at any time to the oxygen content, adjustable gas composition, perfect under water power automatic protection device. Additional secondary combustion equipment so that it can maintain in the case of oxygen reduction of CO at a low level, the use of to import oxygen probe permanent use, you do not need to change. Mine explosion-proof switch, automatic ignition device. Operation is safe and easy to use. Is the most practical coal mine fire extinguishing devices. This product is currently free expansion elongated, the new restructuring automatic leveling damping wheels. The machine made of stainless steel. (1) add a secondary combustion system, greatly improving the efficiency of the complete combustion of the fuel, so that the inert gas has greatly improved the quality, in the case of a low O2, CO greatly reduced, injection of inert gas component found. extinguishing requirements. 2 new features "intuitive oxygen monitoring system, the operator can always intuitive to in the boot DEVELOPMENT gas, changes in the oxygen content of the process gas, and can be readily adjusted to the needs (of O23 to 5% range) the stability of the gas composition and fire-fighting tracking provides a good self-control technology. Opened up a new path for the promotion and application of this technology in the field of mine rescue. 3 air supply device and water pump motor of 380V/660V swap device explosion-proof motor, use more secure. 4 fuel system speed motor to directly control the amount of oil hydraulic control more accurate and convenient. Console device signs the certificate with the State Administration of Coal Mine QBCS-32 type electromagnetic starter, more secure and reliable operation, greatly improve the durability. Remove the closed gate at the middle of the host, reducing the length of the host, and the closed door at the entrance of the fan, easy to operate, also avoid gas injection after the shutdown, accident forgot to shut the door closed.
