Fan Overview:
.uses either a single-stage or dual-stage impeller configuration based on the operating conditions specified by the user. All blades are made of forged aluminum alloy, offering excellent specific strength and safety margins.
Fan Features:
1. The fan uses either a single-stage or 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. Choosing the option to adjust the blade installation angle during operation requires additional components such as a servo hydraulic cylinder, servo adjustment drive unit, electric actuator, and hydraulic control station.
4. The fan is equipped with an electric brake device with safety protection measures. During braking, the brake force is gradually increased by the deformation of compression springs, preventing sudden increases in brake force that could damage the ventilation equipment.
5. The fan achieves more than 40% reverse airflow across the full performance range.
6. The fan uses rolling bearings with thin oil lubrication, with forced oil supply from a lubrication station. 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.
7. The blades are designed with a twisted airfoil shape, and the installation angle is steplessly adjustable between 0° and 50°.
8. There are two methods for adjusting the installation angle of the impeller rotor blades: one allows for one-time adjustment of blade installation angle after the fan is stopped, and the other allows for adjustment of blade installation angle while the fan is running.
Application scenario:
MAF series mine axial flow fan is a main fan with one-time rotor blade angles specially designed for various coal mines and metal mines, and it is also suitable for tunnel ventilation and other departments of national economy.
