In fact, the specific terms of the centrifugal fan performance measurement, which can be divided into the following main purpose, as follows: (1) be familiar with and know how to properly use the fan performance measuring device to measure the performance of the fan; (2) control experiment The specific methods and procedures; (3) Measurement of the performance of the fan, and then convert the results obtained into a characteristic curve, and converted into parameters. At present, China's stone processing enterprises, energy-saving method of adjusting the fan are relatively old mine in Xiaoyi centrifugal fans, generally use throttle. When throttle jiexiu mine centrifugal fan, fan flow, mainly by adjusting the throttle valve or damper to be adjusted, throttle large fan, even at low load throttle more than 50 percent However, due to the presence of throttling losses and run deviate efficient district energy waste is very serious. And if you adjust the fan speed centrifugal fan of mine, you can either cancel the losses caused by the throttle, and can ensure the fan is always running in the high zone, so you can achieve significant energy savings. It can be said to run the fan by adjusting the fan speed is an effective way of saving, which also reflects the building materials industry in a new production of the current trend.
