Install the axial flow fan, pay attention to the impeller stage of the front deflector

Release Time：2021-07-20

The axial flow fan that has emerged in recent years is a new type of ventilation and cooling equipment that is environmentally friendly and energy-saving. Because of its large exhaust volume, good ventilation and cooling effect, low noise, small destructive installation and use to the site, low price, and wide application., Long service life and other remarkable characteristics, more and more are loved by users. Axial flow fan is the ventilation equipment that many enterprise workshops will choose.
1. It is also a very important point. The axial flow fan is better installed in the dominant wind direction of the cooling environment.
2. Axial flow fan Regarding the specific installation location of the axial flow fan, this choice is relatively broad. It can be on the wall, on the roof, or on the outdoor floor, which can ensure smooth and fresh air. If there are not enough doors Or windows, when you need to install a special exhaust machine, you must ensure its exhaust volume.
3. When choosing the installation location, be sure to ensure the load-bearing capacity of the frame so that it can support the weight of the entire axial flow fan main body, the air supply duct at the machine port and the maintenance personnel.
4. When installing the axial flow fan, it is necessary to do a good job of sealing and waterproofing between the indoor and outdoor to avoid damage to the machine caused by rainwater leakage.
The axial flow fan should not cause more damage to the original structure of the workshop as much as possible, that is, to avoid the high installation cost caused by complicated construction as much as possible, even the trouble of moving the machine or disassembling and assembling in the future, choose to install on the window of the workshop as much as possible, and choose to install on the lower window as much as possible. Generally, the upper window of the window is fixed for lighting, and the lower window is pushed and used for ventilation, this axial fan-like ventilation and cooling effect is the best.
Front inducer impeller stage.
The ventilator has a fixed front guide with adjustable blade installation angle at the front end of the impeller to generate negative swirling speed before the impeller inlet, while the swirling speed of the airflow at the impeller outlet is zero. As the front guide deteriorates the velocity field and pressure field of the airflow at the impeller inlet, and increases the value of the average relative velocity of the impeller, the loss of the ventilator is increased and the efficiency is reduced. In addition, the noise of the axial flow fan of this type is also increased.
Shandong Xingheng Environmental Technology Group Co., Ltd. is located in Luquantun Development Zone, Dezhou, Shandong, the hometown of FRP in China. The company has Grade II qualification for fire protection facilities engineering, Grade II qualification for construction mechanical and electrical installation engineering, Grade II qualification for environmental protection engineering, and safety production license. It is the first in the industry to pass ISO9001 quality management system certification, ISO14001 environmental management system certification, OHSAS18001 occupational health management system certification, and an axial fan invention patent, A fan utility model patent, environmental assessment, safety assessment, three simultaneous and other procedures are complete.
