The operation of motor and impeller is closely related. The impeller of negative pressure fan can realize ventilation, and the motor can bring a force to the impeller. The anti-corrosion impeller of the fan is basically subject to anti-corrosion treatment, so some corrosive media will not corrode when passing through.
The electrical energy of gas is converted into atmospheric pressure energy. When the negative pressure fan impeller rotates, the gas enters the axial impeller from the inlet, pushes the natural aerodynamic force to increase the impeller blades, and then flows into the guide impeller. The guide vane deviates from the axis and the gas enters the expander.
Suction fan
Impeller is the fan blade we usually see in negative pressure fan, but many people one-sided think that the efficiency of fan is improved because it is faster. The improvement of fan working efficiency is directly related to the speed of fan during normal operation. However, the impeller may be a more energy-saving measure, which can ensure the use of the same electrical energy while improving efficiency. The impeller can improve the working efficiency of the anti-corrosion fan, which has two advantages: the diameter of the impeller and the inclination of the impeller.
Negative pressure fan belongs to axial flow fan, which can design ventilation speed and wind speed according to needs, so that any high heat, harmful gas and dust smoke can be quickly discharged from the workshop. Moreover, the flow of air can take away the heat of the human body and make the human body feel refreshed.
