K Series High Negative Pressure Mine Axial Flow Fan

Fan Overview:

Adopts a dual-stage impeller design. Depending on the fan model and speed, it utilizes either cast or forged aluminum alloy blades, ensuring sufficient safety margins.

Fan Features:

1. The fan adopts a dual-stage impeller design.

2. The mid and rear guide vanes of the fan use a plate-type twisted fixed structure, which alters the airflow pre-rotation at the impeller's outlet and inlet flow field while also supporting the rotor.

3. The fan is equipped with a manual brake device.

4. The fan uses rolling bearings with grease lubrication. A platinum resistance primary instrument is installed on the bearing housing, with a temperature inspection instrument provided. Additionally, a vibration monitoring instrument can be optionally configured to ensure the fan's smooth and stable operation.

5. The product can achieve a reverse airflow of more than 40% across the full performance range.

6. The blades are designed with a twisted airfoil shape, and the installation angle is steplessly adjustable between 15° and 45°.

Application scenario:

The K series high-negative-pressure mine axial flow fan is a main fan with high ventilation resistance specially designed for various coal mines and metal mines. It is also suitable for tunnel ventilation and other sectors of the national economy.
