Common method of controlling temperature fan noise is to install resistive muffler inlet and outlet of the hot air blower. For higher noise requirements of the occasion, you can use acoustic silencer box, and placed between the crew and ground shock absorbers. Taking the above methods, the general availability of significant noise reduction. China is now a lot of noise control equipment factory where the fan manufacturers low price, can provide all kinds of high-temperature fan noise muffler, muffler noise box and shock absorbers. High temperature fan noise issues, technically speaking, in our country has basically can be effectively controlled, high-temperature and low-noise fan has also begun to appear. Common method of controlling temperature fan noise than to introduce you, and hope that we can help you, the factory is mainly engaged in "research and development, production, distribution, sale," as one of the professional manufacturer, Our solemn promise, all products factory are unified developed by our factory, producing Texas fan phone manufacturers and sales. The market price must be the same material the lowest! As the saying goes, look at the price of second-rate products, first-class products by word of mouth in the service-oriented, to the excellent quality principles. Aluminum and steel impeller using the impeller effect is the same, the case generally depends on the use to decide with which the impeller. 1. The proportion of steel is 7.85, while the proportion of aluminum is about 2.7 (usually with aluminum, aluminum can not be used for low intensity), nearly three times the weight difference. Because of its light weight aluminum, power consumption can be reduced accordingly, to play to save energy. 2. The melting point of steel is about 1500 degrees wucheng best fan manufacturers, aluminum is 660 degrees. At high temperatures, aluminum impeller must not be used. 3. steel in the air easily oxidized (Before treated with preservatives, such as galvanized, etc.) fan, but after the aluminum oxide surface to form a dense oxide film, so that it can not continue to oxidation. In the case of a slight corrosive atmosphere aluminum impeller than steel impeller. 4. strength greater than steel aluminum, due to the intensity of the subject, a large fan impellers are generally used steel impeller.
