　　I. Overview

　　FQNO2.5 mining pneumatic pressure type axial flow local ventilation fan (hereinafter referred to as the ventilation fan) is a type of ventilation fan driven by a gas motor. The ventilation fan has a compact structure, small volume, easy installation, safe use, low noise, and is suitable for blowing out gas and harmful gases accumulated in the ventilation dead corners of coal mines, especially in corner areas. The execution standards for FQ2.5 mining pneumatic pressure type axial flow local ventilation fan are: MT 500-2008 "Technical Conditions for Gas (Liquid) Dynamic Local Ventilation Fans for Coal Mines" and Q/ZFJ 008-2013 "FQ Series Mining Pneumatic Pressure Type Axial Flow Local Ventilation Fans".

　　The structural characteristics of ventilation fans are coal mine use, explosion-proof type, and axial flow type.

　　1、 Main specifications, technical parameters, and performance of FQNO2.5 mining pneumatic press in axial flow local ventilation fan

　　Example: FQ № 5.0, F represents ventilation fan, Q represents pneumatic, 5.0 represents impeller diameter of 5.0dm.

　　Normal operating conditions of FQ mining pneumatic press in axial flow local ventilation fan

　　1. Altitude not exceeding 2000m;

　　2. Working temperature:+4 ℃ to+40 ℃;

　　3. Relative humidity of ambient air: not exceeding 90% RH (at+25 ℃);

　　4. No strong vibrations or corrosive gases, etc;

　　5. Installed in the workplace required for coal mines with explosive gas hazards.

　　Performance range of FQ mining pneumatic pressure type axial flow local ventilation fan.

　　The performance of the FQ2.5 mining pneumatic pressure type axial flow local ventilation fan is obtained through actual simulation tests of the standard pipeline network, converted under standard conditions of gas temperature t=20 ℃, gas density ρ=1.2 kg/m3, and atmospheric pressure p=101325Pa.

　　3、 The overall structure, working principle, and working characteristics of FQNO2.5 mining pneumatic press in axial flow local ventilation fan.

　　The ventilation fan consists of components such as a guide vane, impeller, pneumatic motor, and casing. The pneumatic motor is installed in the explosion-proof chamber inside the casing, connected to the impeller through a transmission group and drives the impeller to rotate. The airflow enters the rotating impeller from the guide fluid, and the airflow accelerated by the impeller is deflected by the guide vanes, causing the airflow discharged by the fan to rotate and blow away harmful gases such as accumulated gas in the tunnel.

　　The main components and functions of FQ2.5 mining pneumatic pressure type axial flow local ventilation fan.

　　As shown in Figure 1, the ventilation fan is mainly composed of four main components: impeller, casing, pneumatic motor, and collector.

　　The casing, explosion-proof chamber, impeller, current collector and other structural components of the ventilation fan are all welded with low carbon steel. The pneumatic motor is connected to the explosion-proof chamber inside the casing with bolts. The impeller is welded from the hub and blades and connected to the output shaft of the pneumatic motor through a transmission group. The weight of the impeller is borne by the transmission group, greatly reducing the load capacity of the pneumatic motor and improving the service life of the fan.

　　Characteristics of FQ2.5 Mine Pneumatic Compression Axial Flow Local Ventilator

　　1. Powered by a pneumatic motor, it is safe and reliable to use in environments with explosive hazards.

　　2. The fan impeller is driven by gas and has superior overload protection function. There will be no dangerous phenomena such as strong friction and rigid damage that may occur with electric motor drive.

　　5、 Installation of FQNO2.5 Mine Pneumatic Axial Flow Local Ventilator.

　　1. The ventilation fan has been debugged and inspected before leaving the factory.

　　2. The ventilation fan must be installed in the main airflow of the corner area or on the fresh air side of the partially ventilated blind alley.

　　3. The distance between the outlet of the ventilation fan and the area or working point where harmful gases accumulate should be greater than 3m to 6m.

　　4. The intake pipe of the ventilation fan is a 13mm high-pressure rubber hose, and the exhaust pipe is a 13mm or 16mm high-pressure rubber hose. The joint type is a quick connector, and the length of the rubber hose is 3m to 5m. The hose must be blown clean before connection, and foreign objects should be avoided from entering or remaining in the hose.
