How to Energy-saving Transformation of Axial Flow Fan Fan Key Problems

Release Time：2021-07-20

Axial flow fan is mainly that we now use mechanical equipment more common, now the level of science and technology, we are more familiar with the use of axial flow fan, now the company specializes in the industry, by the consumer recognition and attention.
When the axial fan starts, the current of the motor will be 5-6 times higher than the rated value. The price of the fan will not only affect the service life of the motor but also consume more electricity. During the design of the system, there will be a certain margin in the selection of the motor. The speed of the motor is fixed. However, in the actual process of using the axial flow fan, it is sometimes necessary to run at a lower or higher speed. Therefore, it is very necessary to carry out frequency conversion transformation. The frequency converter can realize soft start of the motor, achieve the purpose of energy saving and speed regulation by changing the input voltage frequency of the equipment, and can provide overcurrent and overvoltage to the equipment, overload and other protection functions.
In a centrifugal induced draft fan, if its fixed parts cause machine vibration, then the price of the fan mainly includes:.
The cement foundation in the fan is too light, or its plane size is too small, etc., the axial flow fan should strengthen the foundation at this time, or re-grouting, the anchor bolts in the fan are loose, or the frame connection is not firm, the specific treatment is to fasten the anchor bolts, or to fasten the connection, the rigidity of the base and volute of the centrifugal induced draft fan is too low, and the price of the fan should strengthen its rigidity at this time.
The main purpose of axial fans is very common. They are cyclone separators in the same direction as the fan blade axis, electric fans, outdoor electric fans for air conditioners are axial fans, and axial fans are due to the fluidity of steam parallel to the fan axis. Usually called "axial flow". Axial fans are usually used in situations where the total flow rate is high and the working pressure is low.
The axial fan fixes the fixed parts and moves the air. The key to the axial fan is the centrifugal impeller and the shell of the electric fan. The structure is simple, but the statistics are very high. The low-noise wall-mounted axial fan and the low-noise wall-mounted axial fan start from the sound source. Starting from the design method of low speed and high pressure coefficient, wide blades, large chord length, twisted blade type and built-in sound-absorbing materials for fan motors are developed.
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.
