　　FBDNO5.0/2*5.5Ventilation fan with low noise and high voltage of 5.5KW, explosion-proof type press in local ventilation fan for mining use

　　Physical fitness is beautiful due to health,FBD5.0/2 * 5.5 ventilation fanShining due to quality,Mining explosion-proof low-noise high-pressure axial flow fanThe quality of a product is advertising,FBD5.0/2 * 5.5 ventilation fanBrand driven by quality, product driven by character,FBD5.0/2 * 5.5 ventilation fanUsed as a pressure type local ventilation fan in coal mines, suitable for local ventilation in mining faces and various chambers.

　　1、 FBD5.0/2 * 5.5 ventilation fanform:

　　The fan is mainly composed of impeller, casing, inlet collector, guide vanes, electric motor and other components. The impeller is welded onto the hub using a twisted flat plate with meridian acceleration characteristics. After dynamic balance verification and overspeed test, it has good aerodynamic performance. The casing adopts a circular shape, and the fan is connected to the silencer function of the air collector as a whole. The outlet is equipped with flow deflectors, which have good airflow distribution and stable pressure.

　　2、 FBD5.0/2 * 5.5 ventilation fanWorking Principle:

　　The local ventilation fan for mining is composed of two sets of working motors, with two-stage impellers rotating relative to each other. The first stage impeller rotates clockwise, while the second stage impeller rotates counterclockwise. Air enters the first stage impeller through the collector to obtain energy and directly enters the second stage impeller. After being pressurized, it is sent out. The role of the secondary impeller is not only to increase the energy of the airflow, but also to have the function of static guide vanes in other types of axial flow ventilation. While obtaining the velocity component in the circumferential direction of the guide, it not only streamlines the energy of the airflow, but also reduces noise.

　　IIIFBD5.0/2 * 5.5 ventilation fanFeatures:

　　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 different ventilation requirements of the excavation face length and roadway, it 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.

　　Adopting an outsourced compound noise reduction device, it has ultra-low noise characteristics and good noise reduction effect.

　　4FBD5.0/2 * 5.5 ventilation fanTechnical performance parameters:

　　This product consists of two working motors, with two-stage impellers rotating in opposite directions. As an ideal equipment for local ventilation in coal mines, this ventilation fan has the characteristics of high air pressure, large air volume, high efficiency, low noise, and long air supply distance.

　　The performance curve of the ventilation fan is made according to the provisions of GB/T1236-2000 "Performance Testing of Standardized Ducts for Industrial Ventilators" to produce standard ducts, conduct performance tests, and convert them into standard state data with temperature t=20 ℃, density ρ=1.2 kg/m3, and atmospheric pressure p=101325pa.

　　VIFBD5.0/2 * 5.5 ventilation fanNotes:

　　The fan voltage is a dual voltage type, generally with two specifications of 380/660 660/1140V. When selecting, pay attention to matching with the mine voltage. When arriving at the mine, follow the wiring diagram to avoid the phenomenon of connecting the wrong wires and burning out the motor.

　　For the convenience of underground installation and transportation, all the ventilation fans currently produced are equipped with built-in noise reduction devices. Customers can confirm whether the noise reduction devices are built-in or external.
