Frequently Asked Questions (FAQ)
Q
What explosion-proof certifications does this coal mine fan have?
This fan meets coal mine explosion-proof standards and holds the MA (Mining Products Safety Mark) certificate. It is certified for safe operation in environments containing gas and coal dust, eliminating hazards caused by electrical sparks and mechanical friction sparks.
Q
What is the advantage of the dual counter-rotating design?
The dual counter-rotating impeller design allows the two-stage impellers to rotate in opposite directions, which increases aerodynamic efficiency by 10–15% compared to single-direction fans, resulting in greater airflow output with lower energy consumption.
Q
What voltage options are available for these fans?
The fans support multiple voltage configurations including 380V, 660V, and 1140V, making them suitable for various underground mine electrical systems. Smaller models (№4) support 380/660V, while larger models support 380/660/1140V.
Q
Can the airflow and speed be adjusted according to mine ventilation needs?
Yes. The fan supports variable frequency speed regulation as well as hierarchical dual-motor control, allowing precise adjustment of airflow volume to meet the specific ventilation requirements of different mining sections and depths.
Q
What is the maximum airflow and pressure this fan series can achieve?
The fan series covers a wide performance range. The largest model (№8.0 with YBF2-250M-2 motor, 2×55kW) can achieve airflow up to 800–492 m³/min and total pressure up to 500–8200 Pa, making it suitable for long-distance, high-resistance ventilation in deep mines.
Q
What is the noise level of these coal mine fans?
All models in this series maintain an A-weighted sound pressure level of 25 dB(A), ensuring a relatively low noise environment during operation. The aerodynamic optimization of the streamlined impellers also contributes to reduced vibration and noise under high-load conditions.
