How to adjust the air volume of centrifugal fan

How to adjust the flow rate of centrifugal fan? How to adjust the flow rate of centrifugal fan in factory? When the centrifugal fan air quantity is insufficient, it will endanger the application of enterprises and can not achieve the actual effect. Today, centrifugal fans can be used in many manufacturing industries. It gets a lot of help in manufacturing and in everyday life. Its main function is the circulation of air. When it comes to centrifugal fans, some customers don’t know how to use them. Although the manufacturer provided the operation manual, but some customers did not follow the above written process to actually operate, resulting in exceptions.
For centrifugal fan customers, the use of centrifugal fan is to achieve the desired air circulation and ventilation effect. As far as the centrifugal fan itself is concerned, whether the concrete performance of air circulation and ventilation can be normal is directly related to the wind speed of the centrifugal fan itself. The effective adjustment of the wind speed of the centrifugal fan can not only make the specific performance of the centrifugal fan achieve good results, but also can effectively reduce the energy of the centrifugal fan. So how to adjust the centrifugal fan, so that the specific performance of the centrifugal fan to achieve good results? Today, my family to introduce the factory centrifugal fan how to effectively adjust the size of the air volume.
The relevant factories adopt centrifugal fan, centrifugal pump AC motor speed regulation renovation has infinite development prospects. AC motor through centrifugal pump speed regulation can play an immediate role in conditioning. It is proved that the effect of energy saving and environmental protection is 30 ~ 60, that the high pressure boiler and centrifugal fan of the boiling heating furnace are maintained by AC motor speed regulating method, centrifugal pump DC frequency conversion renovation with up to 30 ~ 60 energy-saving environmental protection effect HG75. In the final analysis, the use of centrifugal fan and DC frequency conversion maintenance related.
The recovery of wind speed also depends on the transmission ratio changes. The power of the transmission is linearly modified for its flow rate as the cubic meter connection is modified. Therefore, if the air volume or flow is reduced by 20 when regulating the air volume or flow, the power will be reduced by 60. However, it must be noted that the transmission ratio is related to the square meter of the working pressure. When the transmission ratio is reduced by 20, the working pressure will be reduced by 32. Therefore, it must be noted that the operating scale of the technical standard operating pressure can not be the same as that of the Roots-type supercharger, and there is no need to consider the relationship between the transmission ratio and the air pressure. Maybe they have something to do with this centrifugal fan. After all, the centrifugal fan used by the customer must be considered, transmission ratio and air pressure, which must also be differentiated according to special needs.
Flow modification through the intake valve or shut-off valve operation and AC motor speed adjustment, in this adjustment method, DC frequency conversion adjustment method is more effective, more prominent, in the whole process of regulating air flow, in order to avoid too much wind may be too small, must adjust as many times as possible, as far as possible to adjust the air volume to the appropriate location, for the centrifugal fan application foundation.
