Developed jointly by Shanghai Jiaotong University & Zhejiang Shuangyang Fans Holding Co., Ltd., the SWF series mixed flow fan's air pressure is higher than that of axial-flow fan and air flow rate is larger than that of centrifugal fan under the same machine No., and it can be mounted from axial direction, selected by Beijing Bayi Mansion, China Architectural Culture Centre, Shanghai Orient Bright-pearl and many other high-grade civil buildings, factories, mining industry in Shanghai, Guangzhou, Wuhan, etc.. Our products always win customers’ high praise for their low noise, power saving, wide hi-efficiency range, easy mounting, reliable operating, etc.
1. Technical features
This fan adopts the oblique flow meridian acceleration method, designed through CAD system software, multi-objective optimization, and performance prediction. It has the advantages of higher air pressure than axial flow fans of the same model and larger air volume than centrifugal fans. It has the characteristics of high efficiency and wide high-efficiency zone. The sound level of the fan is 2-3dB(A) lower than that of a general axial fan, which can replace medium and low-pressure centrifugal fans and high-pressure axial fans without the need for noise reduction measures, saving investment. Each unit of this product undergoes high-speed dynamic balancing verification before leaving the factory, with a vibration speed of less than 3.2mm/s.
2. Structural characteristics
This product has a smaller volume and a more compact structure than axial or centrifugal fans under the same air volume and pressure. The inlet collector is fixed to the flange with countersunk screws, which does not affect installation, and the impeller and motor are easy to maintain.
3. Quality level
The quality of this product is at the forefront of the industry.
4. Manufacturing process
a. Impeller: The blades are cut and molded by cold stamping, and the hub is stretched and formed from Q235 steel plate. The impeller is welded by a special welding die and verified by a double-sided hard support dynamic balancing machine at high speed, with a balancing accuracy of G3.2 or above.
b. Wind duct: Round by a three core bending machine, flanged by a spinning machine in one molding process, with sufficient rigidity and beautiful appearance.
c. Guide vanes: all cut by plasma cutting and molded by compression molding.
d. Waterproof: When the fan is placed outdoors, a motor junction box rain cover should be installed. The rain cover should be welded to the outer cylinder to completely prevent rainwater from seeping in.
5. Parameter Range
The air volume range is 1500~120000m³/h, and the total pressure range is 120~1300Pa.
