In modern industrial production, the operation of various equipment is inseparable from the effective gas or gas-solid two-phase flow control system. As an important part of fluid machinery, the external rotor fan has won wide recognition for its stable performance. This article will give you a detailed analysis of the working principle of the outer rotor fan and its advantages.
 

Working principle of 1. external rotor fan
 

The outer rotor fan, as the name suggests, is a core component of a rotating shaft installed outside the housing, and a plurality of blades are attached to the shaft to form a rotating airflow. When the motor drives the rotating shaft to rotate, the blades suck in air or other gas, and under the action of centrifugal force, the gas is thrown to the outside of the housing, thereby forming a gas flow. This process not only realizes the transmission of gas, but also completes the compression of gas.

Technical Advantages of 2. External Rotor Fan

High efficiency: The outer rotor fan adopts advanced design concepts and manufacturing processes to make it more efficient during operation. According to the relevant test data, the outer rotor fan is more efficient than the traditional inner rotor fan, which can reach more than 85%.

Low noise: The noise control is fully considered in the design process of the external rotor fan, and the noise is lower during operation by optimizing the blade shape and reducing the speed. After testing, the noise of the outer rotor fan can be reduced to less than 80 decibels.

Wear resistance: The outer rotor fan is made of high-strength and wear-resistant materials, which makes it have a long service life in harsh industrial environments. In addition, the sealing structure design of the fan effectively prevents lubricating oil leakage and further extends the service life of the fan.

Stability: During the operation of the external rotor fan, due to its reasonable structure design, the airflow distribution is more uniform, thereby ensuring the stability of the fan. In the case of large load changes, the external rotor fan can still maintain stable operation.

Easy to maintain: The external rotor fan adopts modular design, which makes repair and maintenance more convenient. In addition, the lubrication system of the fan adopts automatic lubrication, which reduces the maintenance workload.

Application field of 3. external rotor fan

External rotor fans have been widely used in many fields, such as electric power, chemical industry, petroleum, metallurgy, construction, environmental protection, etc., due to their advantages of low noise, wear resistance, stability and easy maintenance.

In short, the outer rotor fan plays an important role in modern industrial production. Understanding its working principle and advantages will help us to better select and use fan equipment, improve production efficiency and reduce operating costs.
