 Roof fan article from: Reason efficient low noise? High efficiency, low noise: the use of advanced CAD software steel roof fan, designed by the multi-objective optimization. DWT-Ⅰ series machines No. 12 # -24 # A total of eight gauge steel roof fan Monopoly fan manufacturers, by changing the speed, angle and leaf-type methods, the expansion of the range of performance parameters to meet the needs of different conditions of use, reach area with fan and system to facilitate energy saving and noise reduction. How should appear abnormal sound roof fans deal with it when the roof fan in the fan industry has now become one of the products used widely, it's ultra-high performance we see in the eyes, but also appears sound roof fan in the application process anomalies steel roof fan manufacturer, then how should we deal with it today, as we detail below: 1, the line is bad or the same phase caused by phase; poor control box attachment performance, or to the fan at the contact line caused by bad phase; two, two-speed fan control box is inconsistent with the actual high and low numbers; 3, the wiring is not reliable and efficient steel roof fan, after running for some time due to take everywhere fever break; impeller modal vibration form the main roof fan by four blades circumferentially different combinations of vibration, caused mainly for this reason is forward-swept blade stiffness is much smaller than the hub stiffness, i.e. blades "soft" and hub "hard"; blade low frequency vibration mode mainly blade overall wiggler for Lord, mainly in the high-frequency wave-based blade bending. From the perspective of the impact of noise considered the first six vibration modes greater impact because of its place as a result of the flow field has a greater impact, resulting in a change in the angle of attack of the blades into the air, creating fluctuations in leaf surface lift, the most serious The situation will produce galloping, have a greater aerodynamic noise and great efficiency. The main treatment method roof fans sound anomalies appear at runtime is that these, we must operate in accordance with the above instructions correctly, the only way to fully demonstrate its performance.
