Furthermore belt wear sometimes baseline vibration within the sub-synchronous vibration table high range, a harmonic frequency of the frequency if the belt speed closer to or driven rotary drive rotation frequency time-frequency, high-Rui high pressure air, sometimes causing unstable vibration. 2, there is damage to the belt vibrates larger belt speed frequency appears on the belt tensioning direction. 3. Other issues belt the belt on the pulley groove, the rocking belt tension caused by constantly changing the vibration frequency of the belt speed increases. 4, 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 or mismatched belts can cause high radial vibration, especially 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, radial vibration, as if Yichun fan belt 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 · (speed * pulley diameter pulley / belt length Nanchang Jin Xiangyun 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 coolers Nanchang, Jiangxi suction fan, Jiangxi household air coolers, Jiangxi chillers, etc. Jinxiang Yun Nanchang in Nanchang plant cooling ventilation equipment industry enjoyed a high reputation with years of industry experience, can provide customers with products and professional services. I believe Jinxiang Yun plant cooling ventilation plant cooling equipment must be your best choice for ventilation equipment. exhaust fan troubleshooting 1, because the oil in the water exhaust fan malfunction caused sake. oil with too much water, fumes contain water vapor, when water vapor condenses encounters cooler pipe into the water, condensed water in the exhaust fan outlet duct fume separator poor drainage situation Through its outlet pipe back into the fan casing, re-entering the motor from the fan casing, causing the coil insulation reduces .2 cause the motor burned out, because the transformation of fan selection is too large. In order to reduce negative bearing housing, the fan outlet 20% off a small throttle opening, ensure that the main fuel tank negative pressure -150 ~ -250Pa Thus, exhaust fans hold pressure, coupled with the outlet throttle opening is too small, resulting in water, oil drain away easily from the case Long-term retention in the fan casing, resulting in motor burned .3 after entering the motor, exhaust fan motor seal failure because the reason there is a problem caused by motor seal problems, resulting in water entering the motor from the fan casing, causing the motor to burn out . causes fan casing pressure - when the blower outlet throttle opening is adjusted to 20%, Nanchang fan factory, prompting the water more easily into the motor, the motor burned exacerbated frequency Nanchang Jin Xiangyun 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 coolers, air coolers Nanchang, Jiangxi suction fan, Jiangxi household air coolers, Jiangxi chillers, etc. Jinxiang Yun Nanchang in Nanchang plant cooling ventilation equipment industry enjoyed a high reputation, has many years of industry experience, can provide customers with products and professional services. I believe Jinxiang Yun plant cooling ventilation plant cooling equipment must be your best choice for ventilation equipment. plant thermal insulation can be separated cooling plant most of solar radiation and heat conduction, heat fan, reducing interior formation of the greenhouse effect. thereby greatly reducing the temperature of the plant, improve plant . The environment is now commonly used methods are the following two options: A, to the powerhouse roof capping insulation cotton cotton insulation is generally used on the roof is glass wool, used a thickness of 50mm, 75mm, 100mm, density of 10kg / m3,12kg / m3,14kg / m3,16kg / m3., installed generally reduce the indoor temperature 5-8 ℃, the construction process is more complex, if the transformation of the old plant to make insulation, need to remove the existing roof, up the steel mesh, in Online laying wire wool, covered with original roof, do water treatment. B, on the roof spraying efficient insulation reflective coating. Such products with excellent insulation properties, can be applied in a variety of surfaces of metal, concrete, plaster, wood structure surface, asbestos, plastic, glass, steel, rubber and so on. 0.25mm thick coating, the effect is equivalent to 10cm-15cm wool effect, it can reflect infrared 99.5%, 92.5% of visible light, the maximum sound effect of 68% to 50% more than average sound effects. Class A fire completely non-combustible. Non-toxic safe, long-lasting durability, service life more than 15 years (in detail with reference to engineering materials may file). Cold Blower, FRP fan wholesale Nanchang (certified), provided by the Nanchang Jin Xiangyun Yichun fan cooling ventilation plant. Nanchang Jin Xiangyun cooling ventilation plant (www.jxytfsb.com) is an industry leader in Nanchang, Jiangxi, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
