Extraction-type local ventilator under the mine:

The FCD series includes 18 machine numbers. For detailed information, please refer to the structure diagram of the FCD series of coal mine extraction-type counter-rotating axial flow partial ventilator. The aerodynamic performance parameters under the standard conditions are shown in Table 1.

d, The composition of the model and its representative meaning

For example

When the ventilator is not in use, it should be placed in a place where the air is circulated and dry to prevent the motor from getting damp and corrosion and other damage of the whole machine. If the motor is damp, it must be dried.

Generally, the whole machine is transported. If it is needed to be disassembled for transportation, it should be ensured that the parts of the ventilator are not damaged.

Ventilator product implementation standards

For the problem of heat dissipation of the motor in the cyclone

The working environment of the fan (containing a large amount of gas and coal dust, gas humidification) determines that the motor cannot be cooled by the air flow of the fan, and the motor must also be isolated from the explosive gas in the extraction-type local ventilator under the mine.

Extraction-type localventilatorsr under the mine can be called the lungs of coal mines "The operation efficiency and reliability of mine fans are the focus of coal mines. Due to the aging of local old mine fans, low operating efficieny, is gradually replaced by high-efficiency and energy-saving fans, a variety of fans came into being, the cyclone is the introduction of foreign 80s new technology after digestion and absorption of mining fans to develop and produce the replacement of products. It is favored by coal mines for its characteristics of high pressure, large flow, high efficiency, compact structure and easy wind resistance.
