Ceiling fresh air ventilation machine is a high-quality fan equipment, in our lives and production has been widely used, its performance advantage has also been recognized by many consumers, but in fact, we are in daily use ceiling type air exchange air-time, or there will be problems, today Xiaobian want to explain is on the ceiling and the new wind ventilators shock signal is issued, how to properly handle. After the vibration signal if the ceiling and the issue of new wind ventilators, we should first check the fan's place is stable, if the smooth, should be the appropriate method of reducing aliasing and spectral leakage, the selection and design of digital filters, basic time domain and frequency domain analysis. The parameters we want the ceiling and the new wind ventilators are transferred to the appropriate state, the only way to run smoothly, which gives us more benefits. Ceiling fresh air ventilation machine vibration signal is issued, our main response is mainly these, only the right to solve the problem, in order to make it run smoothly.
