回转式风机，也称回转鼓风机，是一种用于输送气体的机械设备。它通常由旋转的圆柱体和一个或多个进出气口组成，可以产生较高的压力和流量。回转式风机通常用于工业和建筑行业中的通风曝气、燃气加压和气体输送等领域。下面为大家介绍一下关于它的工作原理，希望对大家有帮助。

Rotary fan, also known as rotary blower, is a mechanical equipment used for conveying gases. It usually consists of a rotating cylinder and one or more inlet and outlet ports, which can generate high pressure and flow rate. Rotary fans are commonly used in industrial and construction industries for ventilation, gas pressurization, and gas transportation. Below is an introduction to its working principle, hoping to be helpful to everyone.

　　回转式风机的工作原理是利用旋转圆柱体的离心力将气体推动到进出口之间。当圆柱体旋转时，由于离心力的作用，空气从圆柱体的进口被吸入，并被带到离心力的作用下流向圆柱体的边缘。在圆柱体的边缘，空气被推出离心机的出口。

The working principle of a rotary fan is to use the centrifugal force of a rotating cylinder to push the gas between the inlet and outlet. When the cylinder rotates, due to the centrifugal force, air is sucked in from the inlet of the cylinder and carried to the edge of the cylinder under the centrifugal force. At the edge of the cylinder, air is pushed out of the outlet of the centrifuge.

　　具体来说，回转式风机通常由旋转的鼓风机体、驱动装置、进气和出气装置等组成。鼓风机体通常由一个或多个圆柱体组成，圆柱体上有许多向外突出的葉片。当驱动装置带动鼓风机体旋转时，葉片将空气带入圆柱体的进口，并将其推向圆柱体的边缘，最终排出出口。

Specifically, a rotary fan typically consists of a rotating blower body, driving device, inlet and outlet devices, etc. The blower body is usually composed of one or more cylinders, on which there are many outward protruding blades. When the driving device drives the blower body to rotate, the blades bring air into the inlet of the cylinder, push it towards the edge of the cylinder, and finally discharge it from the outlet.

　　回转式风机通常有多种不同的设计和类型，可以根据不同的用途和场合进行选择。例如，它们可以采用不同的进气和出气方式、不同的鼓风机体数量和形状，以及不同的驱动装置等。在实际使用中，还需要考虑回转式风机的功率、效率、噪音、可靠性和维护成本等因素。

Rotary fans usually come in various designs and types, and can be selected according to different applications and occasions. For example, they can adopt different intake and exhaust methods, different numbers and shapes of blower bodies, and different driving devices. In practical use, it is also necessary to consider factors such as power, efficiency, noise, reliability, and maintenance costs of rotary fans.
