Centrifugal fan: Where is the difference between centrifugal fan and blower

          What is the difference between centrifugal fan and blower? 

       Motor, commonly known as "motor \motor", refers to an electromagnetic device that realizes the conversion or transmission of electrical energy according to the law of electromagnetic induction. It is a kind of power device that converts electrical energy into mechanical energy; the fan is a machine that relies on input mechanical energy to increase the gas pressure and discharge gas, which is a kind of driven fluid machinery. Some fans are driven by electric motors, and some can be driven by engines.

       Centrifugal fan, the wind pressure is not very large. The compression process of air is usually carried out by several working thrusts (or stages) under the influence of centrifugal forces. Centrifugal wind turbines are square torque characteristics, while root fans are essentially constant torque characteristics.

       If the load requires a constant current effect, a Roots blower is used. Since the Roots fan is a constant current fan, its main working parameter is the air volume, the output pressure changes with the change of the pipe and load, and the air volume change is very small. A roots blower is a high-pressure blower with a roots blower that transports air proportional to the number of revolutions and moves the gas from the suction side to the discharge side. Since the centrifugal fan is a constant pressure fan, the main parameter of the work is the wind pressure, the air volume changes with the change of the duct and the load, and the wind pressure does not change much. Roots blowers generally have large air volume and high pressure.

      Roots blowers were also noisy. If a small air volume is required, the noise requirements are high. The rotary blower is also a constant current fan. The main operating parameters are air volume, the output pressure changes with the change of pipe and load, and the change of air volume is very small. Rotary blower is variable capacity compression, the main characteristics are low speed, low noise, low vibration, high efficiency.
