Mine Press-in Axial Fan:

Mine press-in axial fan is to install the main fan at the entrance of the special air inlet or in the well to send the fresh air flow to the underground, so that the air flow of the entire mine ventilation system is in a positive pressure state higher than the local atmospheric pressure. Way.

Extraction ventilation is a ventilation method in which the main fan is installed at the entrance of the return air well or in the well, to extract the dirty air flow from the underground to the ground, so that the air flow of the entire ventilation system is in a negative pressure state lower than the local atmospheric pressure. The main fans are installed at the entrance of the inlet and return air wells or in the wells to send the fresh air to the well and discharge the dirty air to the ground, so that the air flow of the entire ventilation system is in a state of partial positive pressure and partial negative pressure. ventilation.

The pressure-extraction hybrid ventilation has the advantages of both the pressure-in ventilation and the extraction ventilation. The air flow is concentrated in the inlet and return air sections, the smoke and dust are discharged quickly, and the wind flow is not easily disturbed by the natural wind flow. A better ventilation method to improve the ventilation effect of the mine. The pressure-extraction mixed ventilation method can be used in mines with subsidence areas on the surface or in mines containing radioactive elements.

Mine Press-in axial fan advantages: compact structure, low noise, high wind pressure, good anti-wind energy, stable operation in small flow areas.

Product Features Mine press-in counter-rotating axial flow local ventilator has the characteristics of reasonable structure, specifications, obvious energy-saving effect, low noise and long air supply distance. According to different ventilation resistance requirements, it can be used both as a whole machine and as a graded use to reduce ventilation power consumption and save energy. The length of the roadway is within 2000M without moving the fan to supply air normally, which reduces the labor intensity of workers and saves ventilation time, which is an ideal equipment for local ventilation in mines.
