　　Introduction to FQCNO3.15 Mine Pneumatic Extraction Axial Flow Local Ventilator

　　1.1 Product Features

　　FQCNO3.15 mining pneumatic extraction axial flow local ventilation fan (hereinafter referred to as pneumatic fan) is a new product sold and produced by Tai'an Yucheng Mining Equipment Co., Ltd. This product has the characteristics of compact structure, small volume, light weight, simple operation, convenient maintenance, and good safety performance. The blades and corresponding housing materials of this series of pneumatic fans have undergone friction spark safety testing, ensuring their use in areas with gas.

　　1.2 Main purpose and scope of application

　　The FQCN3.15 mining pneumatic extraction axial flow local ventilation fan adopts a structure driven by compressed air to drive the impeller to rotate. It is suitable for use as extraction type local ventilation in coal mines and can also be used as local ventilation equipment in metallurgical mines, tunnel engineering, etc. It has a wide range of applications.

　　2. Safety precautions

　　2.1 Operators must be trained, familiar with the operation, and qualified before taking up their posts with certificates;

　　2.2 Operators must carefully read this user manual before using the drilling rig;

　　3. Structural features and working principle

　　3.1 Structural Features

　　The FQCNO3.15 mining pneumatic extraction axial flow local ventilation fan consists of components such as collector 1, impeller 2, casing 3, and pneumatic motor 4. The structural components such as the casing and collector 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.

　　The pneumatic motor is a gear motor with a simple structure and long service life. The compressed air is supplied by the underground compressed air pipeline and connected to the pneumatic motor inlet through a rubber hose.

　　3.2 Working principle

　　The compressed air drawn out from the underground 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 and drive the fan impeller to rotate. The impeller does work on the air, making it have energy and discharged from the fan at a certain speed. It is guided by the air duct to the required place.

　　4 Main Technical Parameters

　　4.1 Composition and Representative Significance of Models

　　4.2 Model and Technical Parameters

　　The FQCNO3.15 mining pneumatic extraction axial flow local ventilation fan includes four models, and its main technical parameters are shown in Table 1.

　　5 Installation and Debugging

　　This series of pneumatic fans is equipped with a handle. It can be used for handheld movement or as a suspension hole during use. If placed in a tunnel for use, it must be fixed.

　　The FQCNO3.15 mining pneumatic extraction axial flow local ventilation fan must be installed by a dedicated person.

　　The installation and use of pneumatic fans must comply with the relevant provisions of the "Coal Mine Safety Regulations".

　　6. Use and Operation

　　6.1 Preparation and inspection before use

　　Before using the FQCNO3.15 mining pneumatic extraction axial flow local ventilation fan, it is necessary to check whether all components are complete and whether the connections are correct and firm.

　　Slowly open the air valve, observe whether the rotation direction of the impeller is consistent with the direction indicated on the casing, and check whether the rotating parts rotate flexibly, whether there is any noise, impact sound, or abnormal sound. When everything is normal, the fan can operate normally.

　　The FQCN3.15 mining pneumatic extraction axial flow local ventilation fan should be stopped immediately when the air volume is high or low during operation. Check whether there is any air leakage in the pipeline or if the motor is faulty when manually moving the impeller, and take appropriate measures.

　　If there is any deformation in the casing of the FQCNO3.15 mining pneumatic extraction axial flow local ventilation fan, it should be dealt with in a timely manner. After treatment, the gap between the blades and the casing protection ring should be ensured to be greater than 2.5mm.

　　6.2 Instructions for use

　　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.

　　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.

　　7 Transportation and Storage

　　Pneumatic fans must undergo factory inspection before leaving the factory. After passing the inspection, they are packaged and ready for shipment.

　　Generally for whole machine transportation, it can be transported by land or water.

　　By purchasing the FQCNO3.15 mining pneumatic extraction axial flow local ventilation fan, you will receive sincere service and perfect after-sales service.
