　　Common parameters and technical requirements for vacuum vortex air pump:

　　Pressure: The pressure of a vortex pump refers to the increase in pressure (relative to atmospheric pressure), which is the value of the increase in gas pressure inside the fan or the difference in gas pressure at the inlet and outlet of the fan. It can be divided into static pressure, dynamic pressure, and total pressure. Performance parameters refer to total pressure (equal to the difference between the total pressure at the outlet and inlet of the fan), commonly measured in units such as Pa, KPa, mH2O, mmH2O, etc.

　　Flow rate: The volume of gas flowing through a fan per unit time, also known as air volume. Commonly used Q to represent, the commonly used unit is; M3/s, m3/min, m3/h (seconds, minutes, hours). Sometimes "mass flow rate" is also used, which refers to the mass of gas flowing through the fan per unit time. At this time, it is necessary to consider the gas density at the inlet of the fan, which is closely related to the gas composition, local atmospheric pressure, gas temperature, and inlet pressure. Conversion is required to obtain the desired "gas flow rate".

　　Speed: The rotational speed of the fan rotor. Often expressed in n, its unit is r/min (r represents speed, min represents minutes).

　　Power: The power required to drive a fan. It is often represented by N and its unit is Kw.
