　　1. Model composition and representative significance of FQC4.0 mining pneumatic extraction axial flow local ventilation fan

　　Example annotation: FQC4.0 mining pneumatic extraction axial flow local ventilation fan: F represents the ventilation fan; C represents the extraction formula; № 4 represents an impeller diameter of 4dm, which is 400mm.

　　2. FQC2.8/3.15/4.0 mining pneumatic extraction axial flow local ventilation fan (hereinafter referred to as ventilation fan), mainly used in coal mines with explosive methane gas hazards, for medium and long-distance ventilation of coal mining working faces. Compared with ordinary axial flow fans, using a counter rotating local fan can reduce the number of fans or increase the ventilation distance while generating the same air volume and pressure. It can also be used in stages according to different ventilation requirements to save energy.

　　2. FQC No. 2.8/3.15/4.0 Mining Explosion proof Pneumatic Extraction Local Ventilator Pneumatic Motor is a gear motor with a simple structure and long service life. The compressed air is supplied by the lower air pipeline and connected to the pneumatic motor inlet through a rubber hose. The compressed air drawn out from the compressed air pipeline is connected to the air inlet of the pneumatic motor on the casing of the pneumatic fan through a rubber hose. After opening the valve, the compressed air drives the motor to rotate, which in turn drives the fan impeller to rotate. The impeller works on the air, giving it energy and discharging it at a certain speed from the fan. It is then guided or directly discharged by the air duct.

　　4. Structural characteristics of FQCNO2.8/3.15/4.0 mining explosion-proof pneumatic extraction axial flow local ventilation fan

　　The pneumatic fan of this system consists of components such as a collector, impeller, casing, and pneumatic motor. The casing, collector and other structural components of the pneumatic fan are welded with low-carbon steel plates, while the pneumatic motor is connected to the casing with bolts. The impeller is welded together with the hub, blades, hollow shaft and amplitude plate, and is directly connected to the output shaft of the pneumatic motor.

　　5. Maintenance and upkeep of mining pneumatic extraction axial flow local ventilation fan:

　　To ensure the long-term safe operation of pneumatic fans, attention should be paid to correct use and regular maintenance.

　　1. The pneumatic motor of the pneumatic fan should be removed every three months, the bearings should be cleaned, and sufficient lubricating grease should be added.

　　2. Pneumatic fans should undergo a comprehensive inspection of all components every six months, and any damage should be promptly replaced. During disassembly and inspection, it is necessary to prevent dirt from entering the motor or remaining on the impeller of the pneumatic fan.

　　3. When the pneumatic fan is not in use, it should be placed in a well ventilated and dry place to prevent moisture, corrosion, and other damage. The air inlet and exhaust ports of the pneumatic motor should be covered.

　　The FQC series mining pneumatic extraction axial flow local ventilation fan is an indispensable part of coal mine ventilation fans. Coal mines have the FBD series coal mine explosion-proof press in counter rotating axial flow local ventilation fan, FQC2.8 pneumatic extraction ventilation fan, FQCNO3.15 pneumatic extraction ventilation fan, FQCNO4.0 extraction pneumatic ventilation fan, KCS-230D mining wet vibrating wire dust removal fan, KCS-410D mining wet vibrating wire dust removal fan, KCS120DMining wet dust removal fanIf the power supply in coal mines is not very abundant, compressed air can be fully utilized to drive the extraction type pneumatic fan used in coal mines, which also has excellent performance. Although the ventilation effect is not as large as that of explosion-proof counter rotating axial flow local ventilation fans, it can still solve a large part of the ventilation problems in coal mines.
