The basic design requirements of the exhaust fan fire exhaust fan fire which is one of the common fan, is now used in various occasions, high-temperature exhaust fan fire, it's ultra-high performance we have not unfamiliar, but fire exhaust fan applications require some basic design requirements, we know how much of this information, we take a closer look at: The first is on the chassis design requirements, general fire exhaust fan housing is cylindrical or cone barrel. Cabinet should have sufficient strength and rigidity, the machine should be able to withstand static and dynamic loads, so that deformation and vibration generated by the housing to a minimum. At specified operating conditions, according to last at least 15 years (except wearing parts), the first security operation time before overhaul designed to be less than 18,000 hours. In addition, the exhaust fan models, fire exhaust fan type size, parameters and characteristics should be consistent with the provisions of GB / T3235, the exhaust fan manufacturers, there is a fan in the same series of the same machine number, its components (including spare parts and spare components) should be interchangeable. The basic design requirements for fire exhaust fan is mainly these, we must properly follow the instructions, and thus its performance into full play, everyone in the application process for fire exhaust fan basic design requirements as well as what you do not understand, Please feel free to contact us. How fire exhaust fan bearing location should be repaired to maintain it exhaust fan fire has now become a leader in the wind turbine industry, everyone it has no stranger to ultra-high performance, but on fire exhaust fan bearing location, How should we carry out repair and maintenance of it, today as we detail below: a fire exhaust fan bearings check the oil supply situation, if there is leakage found the box, first tighten the bolts on the cover on it and see. how to effect, does not work, then replace with new packing. II. If you are replacing the fire exhaust fan bearings, we must ensure that the new bearings and bearing housing clean, but also to the new bearing into the oil placed 75 degrees around the set period of time and then come up with the shaft. In the process of loading the bearing, remember forced to install, do not damage the shaft, but also pay attention to maintenance and other supporting equipment. III. General fire exhaust fan bearing lubricant is better replaced once a quarter, at the beginning of running axial fan, when the first oil change, exhaust fan, let the fan is working 200 hours or so, at Change oil in the first one to carry out within two months after the work is checked once a week, to see whether the transformation, normal, you can change the oil two to four months, it would be best to use a unified manufacturers oil, replace the point to note is that you must remove the old oil and clean the fuel tank and then replaced with new oil.
