Furthermore belt wear sometimes baseline vibration sub-synchronous vibration within Taiwan high range, a harmonic frequency of the frequency if the belt speed rotary frequency or relatively close to the driver when driving rotation frequency, sometimes causing unstable vibration. 2, there is damage to the belt speed of the belt will be larger vibration frequency appears in the belt tensioning direction. 3. Other issues belt the belt on the pulley groove, the next swing, belt tension caused by constantly changing the frequency of vibration of the belt speed increases. 4, the toothed belt loosening problem if the belt teeth × RPM ingredients large vibration occurs. 5, a plurality of V- belt drive, if uneven tension will appear each high axial vibration. 6, wear loose belt or mismatch will cause high radial vibration, particularly in the belt tensioning direction. 3, 1) Check the belt radial vibration frequency multiplier at 2,4,6. If a larger peak, then there is a fault. 2) Check the axial vibration suction fan purchase, if the radial vibration, like a belt is also at a greater frequency doubler peak, compared with a pulley misalignment. 3) 2, 4, 6 in the time domain waveform peak per revolution. Belt Frequency = л · (pulley speed * pulley diameter / length of the belt Nanchang Jinxiang Yun plant cooling ventilation equipment is a professional sales suction fan, cooling water curtain, air cooler Suppliers: suction fan Nanchang, Nanchang FRP suction fan Nanchang curtain, wet curtain Nanchang, Nanchang household air coolers, air cooler Nanchang, Jiangxi suction fan, Jiangxi household air coolers, air cooler, Jiangxi, etc. Jinxiang Yun Nanchang Nanchang plant cooling ventilation equipment industry enjoyed a high reputation, has suction fan for many years of industry experience, can provide customers with products and professional services. I believe Jinxiang Yun plant cooling ventilation plant must be your best choice for cooling ventilation. Precautions fan base requires installation of a, fan level, sturdy, and the basis for highly ≥200mm. b, fan and duct using a hose (flexible material without burning) connection, the length of not less than 200mm, import and export of the same diameter and fan size. In order to ensure the hose in the system during operation distortion does not appear, you should install the appropriate degree. For the fan mounted on the suction side of the canvas hose, install a little more tight, to prevent the fan operation is drawn to reduce the size of the canvas hose section. c, fans must steel bracket fixed in concrete, based on the need to increase its steel frame and between the fan base rubber damping pad. All fan and motor assembly are mounted on one piece steel frame, steel frame vibration to be mounted on top of the pad suction fan base Buying, damping pad is best to use porous rubber plate. d, the diameter of the fan outlet only larger, not smaller, and finally outlet to install insect nets, tend to be increased on the wind when the wind and rain hat. Nanchang Jinxiang Yun plant cooling ventilation equipment is a professional sales suction fan, cooling water curtain, air cooler Suppliers: Nanchang suction fan, FRP suction fan Nanchang, Nanchang curtain, wet curtain Nanchang, Nanchang household air cooler, air cooler Nanchang Jiangxi suction fan, Jiangxi household air coolers, air cooler, Jiangxi, etc. Jinxiang Yun Nanchang Nanchang plant cooling ventilation equipment industry enjoyed a high reputation in the small suction fan, has many years of industry experience, can provide customers with products and professional service. I believe Jinxiang Yun plant cooling ventilation equipment must be your plant cooling ventilation equipment the best choice. suction fan of comparing the suction fan, is the use of a large amount of exhaust axial fan to create a negative pressure ventilation for short. suction fan appearance is generally square, shell material, mostly galvanized sheet also have fiberglass flared suction fan. suction fan cooling effect due to the low investment costs, running low power consumption and many other advantages, thus becoming the majority of factories the best choice for cafes, farms, greenhouses and other places of ventilation and cooling. suction fan on the market today, many brands, many manufacturers to reduce costs, raw materials and other aspects of cutting corners, resulting in the appearance of seemingly identical fan, there is quality . a big difference and some cottage factory, only a few people were simple assembly patchwork, for the quality of products to ensure that consumers can not choose how to do one, look at the appearance of the fan:? Good fan products, shell generally use 1.0 mm high-quality galvanized sheet, look plump, heavy weight. Views are generally used 0.6mm sheet. Second, look at the motor: good products, motors commonly used aluminum. Or foot steel weight, appearance, good anti-rust treatment. Views are generally poor motor housing, even with aluminum instead of copper wire to make the motor coil. Third, look at the details: Good company's products, technical updates generally based on market demand. Dust suction fan FRP fan _ _ Nanchang Hengfeng County Jinxiang Yun suction fan cooling ventilation is provided by the Nanchang plant.
