How it works: the energy when the impeller rotates, the gas enters the impeller axial fan model parameters from the axial inlet by pushing on the gas by the impeller blades increases, then flows into the vanes. Vanes will deflect airflow into the axial flow axial fans, while gas is introduced into the diffuser tube, and further the gas pressure is converted to kinetic energy, and finally the introduction of the work line. Work axial fan blades similar to airplane wings. However, the role of which is to lift up on the wing and supports the weight of the aircraft type axial fans, axial fans and the fixed position and air movement. Cross-sectional axial fan is generally airfoil. Blades may be fixed position, and to be rotating about its longitudinal axis. Blades and the blade pitch angle or the air flow may be adjustable or not adjustable. Changing the blade angle or pitch is one of the main advantages of axial fan. Small blade pitch angles produce lower flow rate, while increasing the spacing may produce a higher flow rate. Advanced axial fan capable of changing the blade pitch (which is quite similar to a helicopter rotor) when the fan is running, thereby correspondingly varying the flow rate. This is called variable pitch (VP) axial fans. Energy: the transformation editor axial fan at startup, the motor current will be 5-6 times higher than nominal, not only will affect the life of the motor and consume more electricity system was designed on the motor selection will leave. a certain margin, the speed of the motor is fixed, but in actual use axial fans brand, sometimes you want to run at a lower or higher speed, frequency transformation is therefore very necessary. Drive motor soft start can achieve by changing the frequency of the input voltage equipment to achieve the purpose of energy-saving speed, and give the device to provide overcurrent, overvoltage, overload protection.
