Structure and working principle of centrifugal fans

The basic structure of centrifugal fans includes several main components such as impellers, air inlets, air outlets, and fan casings. The impeller is the core component of the fan, and its shape is usually a curved blade. The number, angle and material of the blades will directly affect the performance of the fan. Under the action of the impeller, the air flow is accelerated and discharged outward, creating a pressure difference and pushing the air through the entire wind system.

The air inlet and outlet are used to guide the air flow into and out of the fan respectively. The design of the centrifugal fan casing is crucial to the guidance and speed control of the air flow. Reasonable casing design can effectively reduce air disturbance, improve the efficiency of the fan, and extend the service life of the fan.

In the working process of the centrifugal fan, the speed of the impeller is the key factor in determining the air flow speed. The higher the speed of the impeller, the more significant the effect of air flow acceleration, thereby providing higher wind pressure. This is also one of the reasons why centrifugal fans can still work stably when high wind pressure and low flow are required.

Selection and design of centrifugal fans

The selection of centrifugal fans needs to be based on specific usage requirements, usually involving the fan's air volume, air pressure, noise, energy efficiency and other aspects. The air volume of the fan refers to the amount of air passing through the fan per unit time, and the air pressure refers to the pressure required for the fan to overcome the system resistance. Choosing a suitable centrifugal fan requires comprehensive consideration of factors such as the total resistance of the system, the temperature and humidity of the working environment, and the noise requirements.

In practical applications, different types of centrifugal fans can be optimized according to their working characteristics and design purposes. For example, for ventilation systems that require higher static pressure and lower flow, a centrifugal fan with a larger impeller diameter and higher speed can be selected. For systems that require higher air volume, a fan with low air pressure but larger air volume may need to be selected.

Special attention should also be paid to the durability and stability of the fan during the design process. High-quality materials and precise manufacturing processes can significantly improve the service life and operational reliability of the fan, and reduce system failures and maintenance costs.
