Mine explosion-proof local exhaust fan

Date of issue:2022/12/5 16:36:15 Number of Views:

The mine explosion-proof local exhaust fan has the characteristics of compact structure, low noise, high wind pressure, large flow and high efficiency. According to different ventilation requirements, it can be used in opposite directions or as a stand-alone machine. When using counter-rotating ventilation, the ventilation distance can be increased, and when the distance is shorter, a single machine can be used, and the air volume remains unchanged, thereby reducing energy consumption and saving energy. Its compact structure is convenient for transportation and installation in engineering construction. Its structural type is mine explosion-proof type, counter-rotating type, with muffler device, and extraction type local fan.


The motor installation structure is IMB5, which is installed by flange, the flange is connected with the core cylinder by bolts, and the motor is cooled by the gas delivered by the impeller. The fan with motor power above 30KW is equipped with a non-stop oil filling device, which can add lubricating oil to the motor bearing during operation. The rated voltage of the matching motor can be made 380/660V or 660/1140V according to user needs. The fan can reverse the reverse wind, and the reverse wind rate can reach more than 60%.


The fan is designed to be installed horizontally, its service life is not less than 5 years, and the safe operation time before the first overhaul is designed to be not less than 2500h.
