Product Description

SDF tunnel construction axial flow fan

SDF tunnel construction axial flow fan is a special supply fan and an exhaust fan for vertical (inclined) shaft supply and exhaust ventilation in the extra-long tunnel. It is widely used in the centralized supply type, centralized exhaust type, and combined supply and exhaust type of tunnel longitudinal ventilation, and is also suitable for semi-horizontal, full-horizontal, and tunnel auxiliary ventilation. It can be used according to the specific performance parameters of the design, The installation angle of the blade can be adjusted by using different impeller diameters or the same impeller diameter to meet the requirements of air supply and exhaust with different air volume and pressure.


product mix
The fan is composed of five parts: collector, inlet silencer, primary group, secondary group, and outlet silencer
B Each stage is driven by a motor with the same rated power. The impeller is directly connected to the motor shaft. The rotation direction of the impeller between the two adjacent stages is opposite. After entering the first stage impeller to obtain energy, the gas is accelerated and discharged through the second stage impeller. The rear stage impeller has both the static blade function of the axial flow fan and increases the gas flow, thus achieving higher air pressure and efficiency.

C The fan can be disassembled from the middle flange and used in a single section, but pay attention to safety to prevent the impeller from being damaged due to the suction of foreign matters.



Performance characteristics

1. According to the characteristics of tunnel construction ventilation and airflow characteristics, new energy-saving products are developed.

2. Long air supply distance, high efficiency, low noise, and large air volume.

3. The impeller is light in weight, strong in strength, and of ultra-high balance grade, extending the service life of the fan motor;

4. Blade angle can be adjusted according to different ventilation requirements.

5. The muffler is optimized to achieve a good noise reduction effect.

6. The fan adopts a special frequency conversion control cabinet, which can adjust the air volume continuously, conveniently, and reliably. Users can select the best air volume and air pressure according to the real-time situation of tunnel excavation, so as to achieve the best energy saving in system control.

7. Carry out simulation analysis on the simulation site, optimize the blade shape, and make the relationship between the fan air volume, air pressure, and efficiency match best, and its efficiency can reach more than 80%, so as to achieve the best energy saving on the fan structural performance.

8. According to different tunnel construction conditions, the fan shall be customized and designed to achieve the best match between the fan and the construction conditions, so as to achieve the best energy saving in the construction conditions.

Our Advantages

 

 

Strict quality standards, precision machining, and other spare parts and design maintain product stability, strictly select product parts suppliers, and perfect after-sales service system to allow customers to enjoy a new experience

Our company has introduced the latest research results of the Chinese Academy of Sciences, C4-II ternary flow wing twisted blades, which have high aerodynamic efficiency.
The surface of the ventilator impeller blade is sprayed with advanced super-resistant (CN) metal material to form a wear-resistant, anti-corrosion protection layer on the surface of the blade. The wear resistance of the blade surface is 10 to 50 times higher than that of the ordinary carbon steel material, thereby greatly prolonging the service life of the blade.

 

Quality assurance measures:

In long-term production management, our company has formed a set of standardized process control measures and control points, which can provide users with high-quality products in all directions. Our company has a good reputation and is an enterprise that users can trust.

Our company has obtained the IS09001 certification from the International Organization for Standardization (see Enterprise Qualification Materials for details). We strictly standardize the operation process and control points of product manufacturing

 

After Sales Service

 

When the equipment of the buyer is installed, our company is responsible for on-site installation guidance, personnel training and commissioning of test-drive, The separately purchased fan accessories can be used for telephone connection guidance and debugging

Our company guarantees that the structural safety, aerodynamic performance, running noise, and appearance, quality of the supplied ventilators can be checked and accepted by relevant departments.
