Small metal axial flow fan descriptionSource:Guangzhou Liying Fan Technology Co. Ltd.Author:angyLink:http://www.liyingfan88.comViews:98times
One, the basic principle and Application Small metal axial flow fan is also called the local fan, is a fan of metallurgy, chemical industry, light industry, food, pharmaceutical and civil construction, industrial and mining enterprises commonly used, but different from the wind machine, the motor and fan blades are in a cylinder, rely on the blade of axial flow fan drive air flow, flow into the impeller axial fan, approximately in the cylindrical surface along the axis direction of flow, for local ventilation; small metal axial flow fan has the advantages of compact structure, can save a lot of space, convenient installation, stable and reliable, low noise, ventilation ventilation effect, safety, function characteristics of the selected range such wide; can also be connected wind wind sent to the designated area, at the same time in a longer interval between the exhaust pipe installed in series, in order to improve the air pressure in the pipeline; if the shell is removed, and can also be used free fan, because of high volume and equal pressure, so the site wide application in optoelectronics industry, environmental protection and energy saving industry, the automotive electronics industry, commercial kitchen, large UPS power supply, inverter, satellite communication, CNC machinery, medical equipment, stage lighting and surrounding radiation fields. Strengthen the ventilation or cooling purposes. Two, technical standard Fan key to system transmission and distribution of energy saving, and ventilation is good or bad is the fundamental fan selection, small metal axial flow fan can do local ventilation cooling, the cooling effect is best, unit energy consumption is minimum, is particularly important in advocating energy conservation today, so the production and manufacture of fan in strict accordance with the requirements of product standards selection of fan products, optimal model. Small metal axial flow fan manufacturing and fan detection based on the standard GB/T 1236-2000 "industrial fan standard duct performance test," GB 10178-2006 "industrial fan performance testing in situ," JB/T 6411-1992 "HVAC, air conditioning with axial flow fan," JB/T 10562-2006 "general purpose axial flow fan technology" GB 19761-2009 "ventilation conditions, energy efficiency and limit the value of energy saving evaluation value"; fan noise detection and vibration detection is mainly based on GB/T 2888-2008 "fan noise measurement method," JB/T 8690-1998 "industrial fan noise limit," JB/T 8689-1998 "fan vibration detection and its limits," GB/T 3767-1996 "acoustics - Determination of sound power levels of noise sources over a reflecting plane engineering method in an essentially free field detection project" the main air flow, pressure, power, speed, current, noise, vibration, life etc. Three, product performance Guangzhou small metal Axial Flow Fan Ying fan technology limited production, is composed of the outer rotor blade + built-in fixed metal enclosed motor + aluminum alloy shell, technical principle and production technology in Germany on the basis of ebmpapst, improved the production process and product characteristics of innovation is our unique, compared with the same products, it has high speed, low power, high temperature resistant, small vibration, low noise, large air volume, long life and stable product quality characteristics, has become a small metal axial flow fan of leading domestic manufacturers Four, product features 1, the outer rotor metal blade: by a punching blade mold, welding machine + professional design tool for automatic laser welding, welding overall angle of 100% welding stability and leaf blade welding with the unity of the initial design quality requirements and quality; metal blade is directly welded on the outer rotor, the metal blades and external rotor as a whole, improve external rotor thermal efficiency, increase the fan itself radiating area and the outer rotor running its own weight, and the outer rotor metal blade all do electrophoresis surface treatment, resulting in power, temperature, noise level, anti-corrosion and life performance, superior in energy saving similar products consumption, and requirement of plastic blade product performance on the market are not comparable 2, a built-in enclosed motor: motor selection of key materials are imported or domestic famous enterprises of high grade production, with automatic winding machine and vacuum impregnation + professional design fixture assembly production, ensure the built-in enclosed motor torque, small power consumption, the advantages of waterproof and dustproof grade, and similar products by adjusting the gap to achieve the effect, not comparable, at the request of the same environmental performance so far, before the technology and materials are not updated, the product design is the most effective and stable structure principle 3, aluminum alloy shell: by surface electrophoresis processing professional mold + large alloy die-casting molding, aluminum alloy shell can ensure the fan safety, but also ensure the wind pressure, air flow into the impeller axial fan produced more centralized, achieve better radiating effect Five, other description 1, voltage classification: 115V, 230V, 380, and double voltage selection (110 and 220 dual voltage selection) of various small metal axial flow fan products, can also according to customer need special production of high voltage products 2, the environment temperature: ~75 ℃ fan ambient temperature using -10 ℃, also have high temperature fan -30 ℃ ~95 ℃ or -30 ℃ ~180 ℃ higher environment temperature use 3, dust and damp proof: a fan of normal IP54 level in use, can also be used to completely waterproof fan products customer demand special production
