　　1、 FBDNO6.3/2 * 22 mining press in ventilation fanPurpose:

　　This product is mainly used as a pressure type local ventilation fan in underground mines, suitable for local ventilation in mining faces and various chambers. At the same time, it is also applicable to local ventilation situations in other mines and various tunnel ventilation. Mainly used as a pressure type local ventilation fan in coal mines, it is also suitable for local ventilation plants and various tunnel ventilation in other mines.

　　2、 FBDNO6.3/2 * 22 mining press in ventilation fanProduct Features:

　　It is a widely used mining ventilation design. Compared with general axial flow local ventilation fans, this ventilation fan has the advantages of compact structure, high air pressure, large air volume, low noise, high efficiency and energy saving, stable performance, and long ventilation distance. The ventilation fan can supply air normally without moving within a tunnel length of 2000m, reducing the labor intensity of workers and saving ventilation time. It is an ideal ventilation equipment for coal mine excavation working faces.

　　The motors are installed in a sealed cover inside the main air duct of the fan. The sealed cover has a certain degree of pressure resistance, which can isolate the motor from the gas containing gas in the fan flow channel, and also play a certain role in heat dissipation. The sealed cover is equipped with two rows of streamlined air ducts, which are connected to the ground atmosphere through the main air duct, allowing fresh air to flow into the sealed cover while maintaining a positive pressure state of the air inside the cover during the operation of the fan.

　　3、 FBDNO6.3/2 * 22 mining press in ventilation fanDesign standards:

　　Execution standards for ventilation fans: Enterprise standard Q/SDTS002-2007 "FBD series explosion-proof pressure type counter rotating axial flow local ventilation fan for mining" and industry standard MT222-2007 "Technical conditions for local ventilation fans for coal mines". The ventilation fan is designed to be installed horizontally, with a service life of not less than 5 years, and a safe operating time of not less than 13000 hours before the next major overhaul.

　　5、 FBDNO6.3/2 * 22 mining press in ventilation fanStructural features and working principle:

　　Overall structure, working principle, and characteristics: This product has two impellers installed close to each other, which are driven by two motors to rotate in opposite directions. The airflow enters the first stage main engine along the axial direction from the collector end, and after being accelerated by the first stage impeller, the airflow direction is deflected and flows into the second stage main engine. After being accelerated again by the second stage impeller, the airflow direction is reversed and discharged from the end along the axial direction, thereby making the airflow flow. It has the characteristics of compact structure, low noise, high efficiency, good anti wind performance, high wind pressure, stable operation in low flow areas, and wide range of efficient applications. According to the length of the excavation face and the length of the tunnel

　　The same ventilation requirements can be used as a whole machine or in stages, thereby reducing energy consumption. Energy saving is an ideal equipment for long-distance local ventilation in mine excavation.
