The way to judge the efficiency of centrifugal fan
We use centrifugal fans in order to achieve a certain ventilation effect in the place of use, which will improve the air quality of our production and life, and the use efficiency of the fan is related to the effect of ventilation and ventilation. Centrifugal fan manufacturers produce different types of fans, the results achieved and the use of efficiency is also very different.
You can drill one hole at the inlet and outlet of the centrifugal fan to measure the static pressure of the inlet and outlet of the centrifugal fan. According to the static pressure of centrifugal fan, the operating efficiency of the fan is estimated. This method is relatively simple, does not require users to know a lot of expertise, and this method will not affect the normal use of centrifugal fans.
The inlet of some centrifugal fan is equipped with adjustable air valve. If the opening degree of regulating air door is less than 95%, the centrifugal fan must be in low efficiency operation state. For centrifugal fan with hydraulic coupling adjusting speed, the mechanical loss of coupling is 5% at rated speed and 28% at 75% rated speed, so it can be seen that the mechanical loss of coupling is 5% at rated speed and 28% at 75% rated speed. The operation efficiency of centrifugal fan with hydraulic coupling speed regulation will be much lower.
These methods can help users to measure the performance of centrifugal fans. These methods are also the methods we often use to determine the efficiency of centrifugal fans. All the methods we provide are those that require a certain amount of technology before they can be operated. Therefore, our users are required to master a certain knowledge of the fan.www.jnblower.com
