Jin Xiangyun 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 Jin Xiangyun plant cooling plant ventilation equipment must be your best choice for cooling ventilation equipment! Higher temperatures where vehicle maintenance, petrochemical, paint plating, textiles, clothing, glass, rubber, printing, toys, electronics, food processing, laundry, etc.: Scope industry. Civilian areas: cafes, supermarkets, cafeterias, waiting rooms and places of entertainment. Agricultural areas: large farms, greenhouses, sheds and livestock farm. Suction fan choice in terms of technology as follows: First, homeostasis homeostasis is an important indicator of the quality of the fan. Good suction fan, an excellent dynamic balance in operation there is little vibration and the noise will be greatly reduced. Suction fan can be observed through the dynamic balance test machine when bad choices. Second, the size of the noise can be achieved by listening to the sound of the noise fan at runtime. Third, the size of the air volume air flow can be used to test the following two ways. 1, observed in the fan blades running ahead shutters. Cooler air volume multifunction how to sell, blinds certainly leaves are flat. If the blinds are down with the blade, not the level of air coolers, air volume fan then certainly did not meet the design requirements. 2, standing in front of the fan 3 m place feel pressure. Fourth, the current meter measured motor current is available.

Wind turbine Diagnosis: 1, cantilever fan imbalance and horizontal axial vibration value should almost 2 vibration, belt loosening / wear or vibration characteristics do not match the problem (a) 1, belt wear problems generally occur in the vibration spectrum will appears 3 to 4 times the frequency of the vibration frequency harmonic vibration belt, belt vibration frequency is typically 2 × dominant. Moreover belt wear is sometimes higher baseline vibration within the sub-synchronous vibration platform range, a harmonic frequency of the frequency if the belt speed rotation frequency closer to the driver or driven chiller models offer time-frequency rotary table, sometimes causing vibration instability . 2, may damage the belt speed of the belt of large vibration frequency in the belt tensioning direction. 3, other problems make the belt on the pulley belt slot, the next swing, belt tension caused by constantly changing the frequency of vibration of the belt speed increases. 4, if the toothed belt loosening problem belt teeth × RPM ingredient large vibration occurs. 5, a plurality of V-belt drive, if uneven tension will appear each high axial vibration. 6, loose or worn belt mismatch will cause high radial vibration, particularly in the belt tensioning direction.
