Run introduce large-scale use of centrifugal fan running and stopping the use of terms 1. Large centrifugal fan (1) fan commissioning qualified, should the fan casing on the surface of the insulating layer bandaging Nanchang fans ex-works, the use of insulating materials in order to reduce machine Shell external heat propagation, protection bearing safety. Moreover, the thickness of the insulating layer should control the wholesale Nanchang fans, but also be able to facilitate maintenance and removal. (2) The supply situation of the bearing, vibration and bearing temperature should be checked regularly to be able to allow the normal functioning of the fan. (3) The fan just started working offer, vibration bearing parts of Nanchang fans are very small, but with the increase in use of time, the vibration will be gradually increased. Once the maximum limit of the fan is reached, must be shut down for repairs, otherwise continue to use it, there will be problems, danger, damage to the fan. 2. Large-scale centrifugal fan parking (1) parking fan Normal Normal stop Nanchang fans, which operate as follows: first off its heat source, then the fan speed to a minimum, let slow turn, until the temperature was lowered to normal temperature cabinet, then stop the main motor. (2) there is a sudden unexpected stop is the case, had unexpected stop, when the unit is in hot shutdown, the disk drive should be artificial, until the cabinet temperature dropped to normal the following so far. Nanchang Jin Xiangyun plant cooling ventilation equipment is a professional sales suction fan, cooling water curtain, chiller suppliers. Jinxiang Yun cooling ventilation equipment | suction fan Nanchang | Nanchang FRP suction fan | curtain Nanchang | Nanchang Pad | Nanchang home chiller | Nanchang chiller | Jiangxi suction fan | Jiangxi home air cooler | cooling fan, Jiangxi, Nanchang gold clouds 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. Centrifugal fan of some of the basics (1) before installation of the various components of the fan to be checked, parts are intact, ministries coupling is close, the direction of rotation of the impeller is correct and transmission group is rotating flexible. (2) should be installed in accordance with the requirements for installation. You can not have a foreign object into the fan, and later installed, should make the necessary lubrication. The normal operation of Note (1) fan normal operation, driving and parking time, if abnormal, should immediately stop inspection, in order to solve the problem. If the problem is relatively large, it will have a downtime. (2) Every fan overhaul, to replace the lubricant. 5. Maintenance Notes (1) Every fan overhaul, to pay attention to all parts of its operation is normal. (2) The fan should be regularly ash, dirt and impurities, but also good corrosion preventive work. (3) when the fan during maintenance and overhaul should be carried out in the parking state. Nanchang Jin Xiangyun plant cooling ventilation equipment is a professional sales suction fan, cooling water curtain, chiller suppliers. Supply: 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, air cooler Jiangxi, Nanchang and other 金祥云 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 must be your best choice for cooling ventilation equipment suction fan suction fan Number of units Number of units needed to accurately calculate how how to accurately calculate the required 1, theoretical calculations: the conventional cooling load calculation formula evaluation the use of the indoor cold, wet load and air supply, selected indoor cooling capacity must be greater than the design requirements of cooling capacity, generally considered 10 percent margin. 2, empirical calculations: (1) defines the number of indoor ventilation: indoor ventilation rate (X) = suction fan total air volume (m3) / [indoor area (m2) x outlet below the height (m)] . (2) General Environmental Requirements ventilation 25-30 times / hour; (3) crowded public places are required ventilation 30-40 times / hour; (4) a production workshop ventilation equipment requirements fever 40- more than 50 times / hour; (5) appropriate increase in the more humid southern region the number of ventilators, while the more hot, dry northern region may be appropriate to reduce the number of ventilators. ACH number of units should be used in the suction fan cooling fan ≥ requirements designed interior volume × / single suction fan selected actual air volume.
