CUSTOMER REVIEWS
Fan Overview:The variable stator blade axial flow fan is a high-efficiency, energy-saving fan developed by our company based on existing domestic and international technologies.
Application Scenarios: It is suitable for waste heat steam power generation in sintering annular cooler projects, flue gas desulfurization projects in the metallurgical industry, and power station projects.
Axial Fan With Adjustable Stator Blades
Feature:
1. High operational efficiency: The fan operates at an efficiency of 83~87%, with a broad high-efficiency range and a wide flow regulation range.
2. Low noise: The fan produces low noise, significantly improving the working environment.
3. Enhanced wear resistance: The fan casing adopts advanced wear-resistant materials and measures in the easily worn areas, extending the overall service life of the fan.
4. Durable impeller: The impeller is welded from high-strength wear-resistant materials, and an anti-wear coating technology is applied to the surface of the blades, providing the impeller with superior wear resistance.
5. Compact and reasonable structure: The fan is designed with a compact and rational structure, making installation and maintenance convenient. The rotor can be disassembled and assembled without removing the inlet and outlet ducts.
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.
Application scenario: The 2K56 series mine axial flow fan is a main ventilation fan specially designed for various coal mines and metal mines. It is also suitable for tunnel ventilation and other sectors of the national economy.
2K56 Series Mine Axial Flow Fan
Fan Features:
1. The fan adopts a dual-stage impeller design.
2. The fan is equipped with a manual brake device.
3. 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.
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 fan can achieve a reverse airflow of more than 60% across the full performance range.
6. The blades are designed with a twisted airfoil shape, and the installation angle is steplessly adjustable between 20°and 50°.
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.
Application Scenarios: 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.
K Series High-Negative-Pressure Mine Axial Flow Fan
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°.
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.
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.
MAF Fan Device Performance Curve
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.
