Running start: axial fan is driven by a motor running, in fact, are the same for any equipment axial fans offer, you want to work together, there must be a similar "engine." In the choice of axial fan motors, hoping to be able to drive the impeller motor up to speed quickly and work properly. Motor starting, including start and accelerate the whole process of electricity. Starting its way into full voltage starting and decompression starter. Reasonable choice of motor starting method, must be based on the capacity of the supply network, the mechanical load on the starting torque requirements, the characteristics of the motor itself and other factors, specific analysis, in order to obtain the specified start time. For example, a large capacity of the grid, the motor starting current does not cause a significant voltage drop in the power line, in addition, the grid lines and equipment allow short-time control through a sufficiently large starting current, can use full pressure start; if the fan When the required starting torque is not corrosion axial fan, motor and power capacity is relatively speaking not very big, mainly considering how to reduce the starting current and the use of vacuum starter. Noise Analysis: When this distance is small, the bit stream and trail changes will have an impact, the blades may also be used as sound barriers, and strengthen the blade near the blade lift pulsation generated column on sound radiation. This effect depends on the lift pulsation-related acoustic wavelength as compared with the size of the blade barrier. In the frequency range of the ratio is greater than 2 axial fan, since the radiation intensity of the impact of this change is caused by the most significant. Therefore, when the upstream and downstream of the radiation noise of the blade has the same number of leaves, and the leaves of the two columns of each of the blades on both sides of the source and at the same time constituting a sound barrier with a rotor blade meet, this effect will be stronger.
