And the driving device is arranged on the cabinet body and used for driving the air supply device to operate.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a high-efficiency cabinet-type centrifugal fan. Background technique [0002] According to the current development situation of domestic industrial and civil buildings, the pipelines of the ventilation system are becoming more and more complex, and the requirements for building ventilation are getting higher and higher. In the fire-fighting ventilation system of industrial and civil construction, due to the complex piping, limited space and large coverage area of ​​the system, the demand for fire-fighting fan equipment with high pressure, small space occupation and flexible outlet angle has increased sharply. As the main equipment of the fire protection system, there are currently two main product applications on the market: one is the traditional axial flow fan, the impeller is directly connected to the structure, and the airflow flows along the axial direction, with the characteri...

AI Technical Summary

Problems solved by technology

As the main equipment of the fire protection system, there are currently two main product applications on the market: one is the traditional axial flow fan, the impeller is directly connected to the structure, and the airflow flows along the axial direction, with the characteristics of fixed airflow direction and small size. However, the fan pressure is generally low; one is the traditional centrifugal fan, the transmission method generally adopts belt drive, and the box-type structure makes the angle of the fan outlet changeable, with the characteristics of flexible airflow direction and large pressure range, but the structure is relatively Complex, large volume, large resistance during the air supply process, and the air supply efficiency needs to be improved. Therefore, the required fire-fighting fan equipment should have: simple structure, high pressure, small volume, flexible air supply direction, convenient manufacture, and convenient Maintenance and other features

So as to get rid of the traditional axial fan's low pressure, fixed airflow direction and the traditional centrifugal fan's complex structure, large volume and low air supply efficiency
