What is the working principle of glass fiber reinforced plastic negative pressure fan?

Glass fiber reinforced plastic (GFRP) negative pressure fan, that is, glass fiber reinforced plastic negative pressure fan, its working principle combines the excellent material properties of glass fiber reinforced plastic (GFRP) with the functional requirements of negative pressure fan, and realizes efficient and stable air flow and negative pressure environment creation.
GFRP is a composite material with glass fiber as reinforcing material and plastic (such as epoxy resin, phenolic resin, etc.) as matrix material. This material has the advantages of light weight, high strength, corrosion resistance, and good insulation, which makes GFRP negative pressure fan have unique advantages in design and manufacturing.
The main function of negative pressure fan is to generate negative pressure through rotating impeller, and then inhale and discharge external air to form air flow. The working principle of GFRP negative pressure fan is mainly reflected in the following aspects:
Impeller design: The impeller of GFRP negative pressure fan adopts special design, and realizes efficient air intake and discharge through precise blade angle and shape. At the same time, the use of GFRP material makes the impeller light and high-strength, and can maintain stable performance at high speed rotation.
Negative pressure generation: When the motor of the GFRP negative pressure fan starts, the impeller starts to rotate. Under the action of centrifugal force, air is sucked into the center of the impeller and thrown to the outside as the impeller rotates. At this time, a low-pressure area, namely the negative pressure area, is formed inside the fan. Under the action of negative pressure, the external air is sucked into the fan to form air flow.
Corrosion resistance and insulation performance: GFRP material has excellent corrosion resistance and insulation performance, which enables the GFRP negative pressure fan to work stably in a humid and corrosive environment. At the same time, this material can also effectively isolate current and electric heat to ensure the reliability of the fan in electrical safety.
High efficiency and energy saving: Due to the light weight and high strength characteristics of GFRP material, the negative pressure fan has lower energy consumption and noise during operation. In addition, by optimizing the design and manufacturing process, the GFRP negative pressure fan can also achieve higher air flow and lower energy consumption ratio.
