coal mine Axial Flow Fan

The FBC (D) Z series coal mine surface explosion-proof extraction (reverse) axial flow ventilation fan can be used as a substitute product for large, medium, and small coal mines, as well as a product for new coal mines. The ventilation fan is equipped with non-stop air injection and oil discharge devices, which can add lubricating oil during operation. When the machine is shut down, the oil drain cover can be opened to drain the waste oil. The ventilation fan can transport underground air containing explosive gases of methane in the medium, and is generally designed for horizontal installation with a designed service life of no less than 20 years. The operating time before the first major overhaul shall not be less than 9000 hours. The impeller of the ventilation fan is equipped with an H62 brass protective ring, which can be used in two processes: riveting and explosive welding.
