Date of issue:2022/12/2 14:39:45 Number of Views:
Mine explosion-proof blower The main technical performance parameters of this series of fans are: air volume Q, full pressure P, full pressure efficiency η, noise (compared with A sound level) LSA, rotating speed n and so on. The maximum efficiency of the series of fans is 86%, and the highest noise does not exceed 85dB（A）. See Table 1 for details of other parameters.
This product can be placed flat on the floor of the roadway, also can be suspended on the wall of the roadway for use. When used on the floor, the air inlet (the collector end) of the fan should not be immersed in water or cement. The gas temperature of the using environment of the fan is -20～50℃, and the altitude should not exceed 1000m. The rated frequency of the power supply used is 50 Hz, and the rated voltage is any class of 380V/660V or 660V/1140V.
The dust content of the gas passing through this product does not exceed 200mg/m3. It should be installed in the air inlet with a gas concentration of less than 1% in the underground coal mine. When the gas concentration exceeds 1%, the power supply should be cut off immediately.
