Coal Mine Fan
Date of issue:2022/12/5 16:05:26 Number of Views:
Mine explosion-proof axial flow main fan is a kind of mechanical ventilation equipment with high utility, high energy saving and strong design specially designed for various coal mines, mines and tunnels. It often adopts an extraction ventilation structure. This series of fans can be designed and manufactured in combination with the ventilation network parameters of large and medium-sized coal mines or mines; the fan adopts an adjustable installation angle design. According to the changes in the working conditions of the mine ventilation network, the blade installation angle can be adjusted in time. The fan is always in high-efficiency and energy-saving operation, and adopts the overall structure of the motor and the impeller directly connected, eliminating the need for a transmission system, and has many advantages such as high efficiency, energy saving, low noise, and easy installation and disassembly. The fan is also suitable for metal mines, chemical mines and other factories and mines that require forced ventilation.
The main fan of this series is a two-stage counter-rotating structure, and the impeller and the motor shaft are directly connected. Tower and other parts. The fan adopts the direct-connected structure of the impeller and the motor shaft, without transmission system, the structure is compact and simple, the operation is stable, the accident points are few, and the energy saving effect is good. The explosion-proof type of the fan supporting motor is explosion-proof type, and the explosion-proof mark is "ExdI".
All blades of the coal mine fan can be adjusted, which can be divided into five working angles of 45 °, 40 °, 35 °, 30 ° and 25 °. The installation angles of the front and rear stages can be the same or different, and can be adjusted to any angle below 45 °. One of the fans can be operated independently, so the adjustable range is extremely wide. In the initial stage of mine operation, only the primary fan can be operated.
