Product Description

How is a Negative Pressure Fan composed? Summer is approaching, and the use of negative pressure fans is increasing. Generally, Industrial Fans are mainly composed of blades, motors, outer frames, protective nets, support frames, louvers, and other components.

The negative pressure fan motor drives the fan blades to generate airflow, and the roof automatic fan is an environmentally friendly natural ventilation device that utilizes the pressure of outdoor breeze or raindrops and the rising pressure of indoor hot air to form a rotating exhaust system for the main unit. Similar to HVLS Fans, they are suitable for ventilation equipment in industrial factories, flower greenhouses, livestock houses, and various buildings.

In the use of negative pressure fan, there is often some noise, and at this time, it is necessary to regularly check whether the connecting bolts and foundation bolts of each component of the negative pressure fan are loose, and whether the bearings are abnormally worn or poorly lubricated. Whether the transmission belt is tensioned, etc. If any abnormalities are found, the vehicle should be immediately stopped for troubleshooting.
Ventilation And Cooling Axial Flow Fan

Rotating components such as negative pressure fan impeller, negative pressure fan shaft, belt pulley, and coupling must undergo strict static and dynamic balance calibration before being assembled into a unit. It is allowed to leave the factory, and the gap between the motor cooling fan blades and the air guide ring should be reasonably selected to effectively reduce the rotating noise of the motor cooling fan blades.

Reasonably select parameters such as the shape and diameter of the motor cooling fan blades. Effectively reduce the eddy current noise of the motor cooling fan. During installation, soft materials such as rubber, soft boards, or felt boards should be placed between the negative pressure fan and the reinforced concrete foundation. Minimize or eliminate the vibration transmitted by the centrifugal negative pressure fan to the reinforced concrete foundation.

In addition, a rubber hose is installed at the inlet and outlet of the negative pressure fan to minimize or eliminate the vibration transmitted by the centrifugal negative pressure fan to the air duct at the rubber hose.
