The main difference lies in centrifugal fans and axial fans: Merge Atlas (2) a centrifugal blower to change the flow of the medium within the duct, but does not change the flow of axial fan duct within the medium; two, the former is more complicated to install 3, the former motor and fan are generally connected by a belt driven rotary wheel, which is generally in the fan motor; 4, the former often installed in the air conditioning unit inlet and outlet of the boiler drums, Fan oven with high temperature axial fan, and so on. The latter were often installed in the duct or duct outlet front end. There are also mixed flow (Francis) fans, axial fans high pressure coefficient ratio, flow coefficient than the centrifugal fan. To fill the gaps between axial fans and centrifugal fans of. Along with easy installation features. Francis (or axial-flow impulse) fan combines axial and centrifugal fans feature, although it looks more like a traditional axial fan. The curved plate-shaped blades welded to the conical steel hub. By changing the angle of the blade inlet in the housing upstream of the impeller to change the flow. The cabinet may have an open inlet, but more commonly, it has a shape bent at right angles, so that the motor can be placed outside the pipe. Excretion shell slow expansion to slow down the flow of air or gas, and the kinetic energy is converted to useful static pressure. Axial fan is driven by the motor running, in fact, any device is the same high temperature axial fan, 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 small axial flow fan, can use full voltage start; torque at startup if the fan is not required, and not in terms of grid capacity is relatively large electric motor, the main consideration how to reduce the starting current and the use of vacuum starter.
