Maintenance overhaul axial fan axial fans, including minor repairs, repair and overhaul of these three parts. 1. Small repair (1) Check the belt tension degree, if not suited to be adjusted. (2) fastening bolt, checking whether the angle of the blade correctly. 2. The content of the repair, including minor repairs, as well as check the couplings, alarm, gear box gear in these areas, but also for filling oil lubrication. 3. The overhaul includes the repair content, but also to check for wet curtain fan blades, gear box, wearing parts, bearings, shaft, transmission, steering system, how much money, for replacement, should be replaced. Finally, we need the fan embalmed. Second, the axial fan 1. Prepare the test before the test (1) units have been completed maintenance and quality to meet the requirements. (2) the site has been cleaned, the machine has been added good lubricants, electrical instrumentation driving conditions have been met. 2. test (1) start the fan Livestock wet curtain fan, to see the fan rotation direction is correct, whether the fan is running smoothly, without exception, the motor current is within the specified range. (2) running one hour, check the gear oil temperature is not greater than 80 ℃, the temperature rise is not more than 40 ℃, the vibration of the bearing is not greater than 6.3mm / s, if not normal, should find reasons to resolve. (3) test, the position of each part should be correct, fasteners should be tightened, there should be no leakage seals, test can be considered qualified.

Centrifugal fan impeller size determines the efficiency of machinery is actually very simple, so-called centrifugal blower fan is only one form, has been able to raise so much power in large part because this depends on the fan impeller . The so-called impeller is what we usually see the fan blades, a lot of people think sided fan efficiency because of its speed is faster. Yes, the work is to improve the efficiency of the fan and the fan speed has a direct relationship. But the impeller is a more energy-saving measures, to ensure that it uses the same energy efficiency at the same time. Impeller centrifugal fan can improve work efficiency of both worlds, one is the impeller diameter, the other one is the degree of tilt of the impeller. If the relatively large diameter of the impeller fan wet curtain, that this centrifugal fan models large enough. So it will effectively enhance the power, which is a large reason why all power is relatively large in size than the fan. There is a degree of tilt centrifugal fan wet curtain wind turbine manufacturer, if the degree of inclination is small, then the power will be relatively small. Conversely, if a large degree of tilt, then centrifugal fan power will be larger. But it is also within a certain range, because after all, the degree of tilt of the impeller is no way to ninety degrees, at most, that is, an acute angle of the inner, should otherwise, this centrifugal blower impeller life will be in the relatively short. Wet curtain fan equipment, Jiangxi wet curtain fan, exhaust fan the fire Jinxiang Yun Jin Xiangyun by Nanchang plant cooling ventilation.
