Centrifugal fan is simply a kinetic energy will be converted to potential energy machinery, it is also the use of such a working principle to achieve a certain area to change the pressure of the function. But because of such a function, it is very widely used in the field of application, this centrifugal fan widely used in factories, mines, tunnels, some buildings ventilation, cooling, dust and so on the field, can be said to be A versatile tool.
The most recent of our lives may be some of the factory workshop used to dust, ventilation, cooling centrifugal fan, then take this occasion used in the centrifugal fan, it can through the characteristics of the fan to ensure that the workshop a certain pressure , In order to ensure the ventilation within the workshop. But theoretically, such a work speed process should be a straight line, that is to say that such a centrifugal fan should be uniform rotation.
However, in the use of real life, such a centrifugal fan is a curve of the work process to carry out. Because the indoor air is with its density, such a density is in accordance with the temperature changes, which allows the centrifugal fan if it is always in a uniform rotation of the case, it can not guarantee the quality of ventilation within the workshop The
And then this new type of centrifugal fan has a characteristic produced, and that is the centrifugal fan power is with the workshop temperature, that is, adjust the temperature changes in a certain area, so that it can be a good way to ensure that the workshop ventilation Happening. Such a function can be said to give this centrifugal fan intelligent effect.
This can also fully reflect the scientific and technological content of this centrifugal fan, but also that such a machine can adapt to a variety of areas of use.
