Technical standards for high-pressure blowers?

Air volume: use 100 to indicate the size of air flow. Air volume = cross-sectional area * wind speed Common units: cubic meters / hour, ie CMH, m3 / hn total pressure: degrees are used to determine the magnitude of air resistance. Units: Pa, Pa
Total pressure = static pressure + dynamic pressure
Static pressure: used to determine the resistance of the airflow, that is, the resistance along the way (system resistance)

Dynamic pressure: the resistance generated by the air when it flows. Dynamic pressure = 1 / 2ρv2
Speed: used to indicate the speed when the fan is running. Waybone interior: RPM (r / min), RPM
Shaft power: the actual energy consumption of the fan. Unit: kilowatt KwChina Blower Fans manufacturers
Motor power: It is the power of the motor equipped with the fan, which must be greater than the shaft power. Unit: Kw
Noise: It is used to indicate the amount of noise generated when the fan is running. Unit: Decibel, dB (A)
Static pressure efficiency: The formula is expressed in SE% (STATIC EFFICIENCY): SE% = A / B A = air volume (m3 / h) * static pressure (Pa) B = shaft power (Kw) * 1000 * 3600.
