Description
SDF tunnel construction axial flow fanSDF 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, 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.

4) All equipment is waterproof and rainproof. Zibo Hengding Fan Co., Ltd. Is located in Industrial Park, Beijiao Town, Zhoucun District, Zibo City, Shandong Province, China. The company covers an area of 12,000 square meters and a construction area of 8,000 square meters. The company has total assets of 27 million RMB and 186 employees, 46 engineers, and technicians. It has passed ISO9001 quality management system certification and maintained long-term technical cooperation relationships with many colleges and universities, such as Xi'an Jiaotong University, Tianjin Nankai University, etc. Now, it has developed into a modern ventilation equipment manufacturing enterprise with first-class testing and producing equipment, high-quality and excellent production molds, strong scientific research and development strength, a strict quality management system, and gradually perfected development. The company has 15 years of production experience, with an annual output of 5,000 sets of ventilators
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.
