Trouble shooting of centrifugal fan and system

If the centrifugal fan problems, users should contact professional maintenance, repair personnel, a comprehensive in-depth understanding of the system status and obstacles, find out the cause of the problem, find out the relevant solutions. Centrifugal fan. Remember, if time permits, try to let these repairmen work on the site. In addition, before solving the problem of centrifugal fan, it is necessary to establish a priority system with strong timeliness and seriousness. It’s necessary. The establishment of the system can effectively protect the interests of both sides.
Classification of abnormal problems of centrifugal fans:
According to the above description, centrifugal fan and its failure reasons have a lot of, so before troubleshooting must find the right direction. The following three types of faults are usually the focus of attention: first, the aerodynamic performance of the centrifugal fan is analyzed. In fact, this performance analysis applies to any calculation of flow, pressure, speed, power, and density. They can compare the number of designs and the relevant five-level parameters. Second, running noise problems. If the noise and vibration amplitude and frequency of the same, centrifugal fan noise will be lower. Its energy content and unit of measurement is DB reference tile. In general, the noise frequency range is much wider than the upper limit of vibration (63 HZ-10 khz) .
The third problem is vibration. This occurs if the amplitude of the centrifugal fan is large, and the larger content is contained in the frequency range, usually 3 Hz or 500 Hz.
