how to check pressure for centrifugal fan
With the advancement of the industry, the role of centrifugal fans has become greater and greater, and the number of centrifugal fans used in supporting production equipment, building ventilators, agricultural services and other fields is increasing. So, how to check the pressure of the centrifugal fan? Let AFL introduce it to you now.
Under normal circumstances, the data obtained by direct performance testing of centrifugal fans is more accurate.
Drill a hole at the inlet and outlet pipes of the centrifugal fan to measure the static pressure at the inlet and outlet of the centrifugal fan. This can test the pressure of the centrifugal fan.
In addition, the adjusting damper cannot be fully opened, which will cause corresponding effects. This will cause uneven airflow at the inlet of the centrifugal fan, if it reduces the aerodynamic performance of the centrifugal fan. It will also cause pressure loss.
The operating efficiency of the fan is estimated based on the static pressure of the centrifugal fan. This method is simple to operate and does not affect production. For a centrifugal fan equipped with a regulating air door, if the opening of the regulating air door is less than 95% during operation, the centrifugal fan should be in an inefficient operation state. It is important that the centrifugal fan can be tested well when purchasing.
