If a centrifugal fan has a certain power, is there a relationship between wind pressure and wind speed? How to judge that the centrifugal fan needs to be shut down for maintenance? In addition, about the centrifugal fan, what other knowledge content is we must What do you know and master? The above questions are all related to the product of the centrifugal fan website, so the correct answer will be given immediately below, so that everyone can understand in time.

1. In a centrifugal fan, if its power is constant, is there a relationship between wind pressure and wind speed?

In a centrifugal fan, if its power is constant, then the two parameters of wind pressure and wind speed are closely related. Therefore, the answer to this question is yes. Moreover, there is a proportional relationship between them, that is, the higher the wind pressure, the greater the wind speed. Therefore, at this point, there can be no misunderstandings.

2. What can be used to determine whether the centrifugal fan needs to be shut down for maintenance?

To determine whether the centrifugal fan needs to be shut down for maintenance, there are some specific aspects or measures, for example, to measure the fan current, or the temperature of the bearing and the casing. In addition, measure the vibration and noise of the fan, or check the ventilation effect of the ventilation system, so that a correct judgment can be made and at the same time, accurate results can be obtained.

3. Why is the adjustment of centrifugal fans important? In addition, why is the air inlet large and the outlet small?

The adjustment of the centrifugal fan is very important, because through adjustment, the fan can play its due role, and in turn, bring good economic benefits to users, so this work will be carried out.

The centrifugal fan has a large air inlet and a small air outlet in order to allow the fan to have the smallest possible air inlet resistance, and to increase the energy conversion as much as possible to avoid losses. Therefore, there will be this specific requirement. Moreover, if the size of the air inlet and the air outlet are the same or smaller than the air outlet, then it will affect the conversion of effective work, and also make the static pressure of the fan smaller.
