Influence of centrifugal fan on high and low temperature test chamber
The circulation system of the high and low temperature test chamber of the centrifugal fan is an important guarantee for the temperature uniformity index. The accuracy of the fan is directly related to the accuracy of the test results of the high and low temperature test chamber. How to judge the quality of the centrifugal fan, the experts gave a guiding opinion:
First, the fan efficiency is not high, the fan efficiency is high, the power is low, and the efficiency is low.
Second, whether the fan performance meets the nominal wind pressure air volume, and the nominal model will meet the pumping air volume required by the actual system.
Third, the vibration value of the bearing part is not high, the vibration value is high, the fan bearing is easy to damage, the vibration value is low, and the bearing life is long.
4. How about the running noise? Noise and environmental pollution, but also energy consumption.
5. The convenience of maintenance, the fan is a specific equipment, which requires regular maintenance and lubrication.
6. The high-low temperature test chamber of Yashilin Instrument adopts imported motor in the centrifugal fan, which has good mute effect, energy saving and long service life, ensuring product air circulation, accurate temperature uniformity and fluctuation index, 100% through third-party authoritative measurement. .
