Mining Rig Exhaust Fan:

Mining rig exhaust fan, it is ok to run only one class of the FBCDZ (formerly BDK) series of fans, and the other class can be used as the backup.

Before the fan is installed, the blade should be adjusted first according to the required angle, and all the screws should be tightened. The motor can be refueled at any time during operation. When in operation, the current, the voltage, the motor bearing and the temperature indicating instrument of the motor stator should be frequently observed and recorded well. If it exceeds the required index of the technical requirements, coal mine explosion-proof double impeller should be immediately stopped for checking.

During the overhaul of the machine, the sealing gasket of the airtight cover should be carefully kept and must not be damaged. Once damaged, it should be purchased from the manufacturer.The highest unit of this series of fans can achieve the static pressure efficiency of 86%, the high-efficiency area is wide, and the static pressure efficiency is more than 70% of 70% or more working area. It can ensure that the efficiency of the main fan of the mine in the three mining stages is all above 75%, which has reversed the low operation efficiency of the main fan of large mines inChina, and saves a large amount of the electric energy.

The working principle of the mining rig exhaust fan:

When the impeller rotates, the gas enters the impeller axially from the air inlet, and is pushed by the blades on the impeller to increase the hungry energy of the gas, and then flows into the guide field. Guide vanes change the deflected gas flow into a mine axial flow fan, and at the same time introduce the gas into the diffuser pipe, further converting the kinetic energy of the gas into pressure energy, and then introducing it into the working pipeline.

The blades of mining axial fans are generally able to rotate at an angle, and most mining axial fans are equipped with a set of blade hydraulic adjustment devices. When the fan is running, through the blade hydraulic adjustment device, the hungry installation angle of the blade can be adjusted, and it is maintained at the *** angle, so that it still has high efficiency when changing working conditions.
