The working principle of Glass fiber reinforced plastic negative pressure fan (glass fiber reinforced plastic negative pressure fan) mainly involves two aspects: negative pressure ventilation and air flow. The following is a detailed explanation of its working principle:
1. Negative pressure ventilation
Definition and principle:
Negative pressure ventilation refers to the formation of a negative pressure environment in a specific area through the action of the fan, so that the external air is sucked into the area, thereby achieving the purpose of ventilation.
In the glass fiber reinforced plastic negative pressure fan, when the fan is started, the blades inside it begin to rotate, generating suction, sucking the surrounding air into the fan, and discharging it through the exhaust port.
Function:
Through negative pressure ventilation, dirty air, harmful gases, dust, etc. in confined spaces such as workshops and warehouses can be effectively discharged, and fresh air can be introduced at the same time to improve indoor air quality.
2. Air flow
Air flow path:
External air is sucked in through the air inlet of the fan, and the suction generated by the rotation of the blades inside the fan forms an airflow.
The airflow undergoes a series of treatments inside the fan (such as filtering, cooling, etc., but the glass fiber reinforced plastic negative pressure fan usually does not have these additional functions and mainly relies on its exhaust capacity), and then is discharged through the exhaust port.
Air flow characteristics:
The airflow generated by the glass fiber reinforced plastic negative pressure fan is directional, usually flowing in one direction from the air inlet to the exhaust port.
The speed and flow of the air flow depend on the power of the fan, the design of the blades, and the size of the air inlet and exhaust port.
III. Practical application
Applicable scenarios:
Glass fiber reinforced plastic negative pressure fans are suitable for various places that require ventilation, especially those workshops or warehouses with problems such as acid and alkali corrosion, high temperature, and odor.
Such as chemical, petroleum, metallurgy, mining, machinery manufacturing and other industries, as well as warehouses and farms that need cooling and deodorization.
Installation and maintenance:
Glass fiber reinforced plastic negative pressure fans are usually installed on walls that need ventilation, with the air inlet facing the outdoors and the exhaust port facing the indoors.
During use, it is necessary to regularly check the operating status of the fan, clean up the debris in the air inlet and exhaust port in time, and keep the fan unobstructed.
