The ventilator is a machine which increases the pressure of gas and discharges the gas by means of input mechanical energy, and is a driven fluid machine. The exhaust pressure is lower than 1.5 x 10^4 Pa. Modern ventilators are widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and draught of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household electrical equipment, drying and sorting of grains, wind tunnel wind sources and inflation and propulsion of air cushion boats and the like; the working principle of the ventilator is basically the same as that of a turbine compressor, but the gas flow rate is low, the pressure change is not large, the change of the specific volume of the gas is generally not required to be considered, and the gas is treated as incompressible fluid; the performance parameters of the ventilator are mainly flow, pressure, power, efficiency and rotational speed. In addition, the magnitude of noise and vibration is also a major technical indicator of ventilators. The flow rate, also known as the air volume, is expressed in volume of gas flowing through the ventilator per unit time. The pressure is also called wind pressure, and refers to the pressure rise value of the gas in the ventilator, and is divided into static pressure, dynamic pressure and full pressure. The total pressure is equal to the difference between the total pressure of the airflow on the section of the outlet and the section of the inlet of the ventilator; the static pressure is equal to the difference between the airflow static pressure on the section of the ventilator outlet and the airflow static pressure on the section of the ventilator inlet; the dynamic pressure is the dynamic pressure of the mean velocity of the air flow over the cross section of the ventilator outlet. On the same section, the total pressure of the air flow is equal to the sum of the static pressure and the dynamic pressure.
