Describes the use and operation of large-scale centrifugal fan 1. Large parking areas of operational use centrifugal fan (1) fan commissioning qualified, it should be wrapped on the surface of the fan housing insulation, the use of insulating materials in order to reduce the housing external heat spread and protect the safety of the bearing. Moreover, the thickness of the insulation should be controlled well, but also can easily access 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, vibration bearing parts is 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 normal parking parking (1) normal stop fan, its operation are: first off its heat source, then the fan speed to a minimum, allowed to slowly turn until the cabinet temperature dropped to normal after, 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.

Maintenance overhaul axial fan axial fan including small repair, repair and overhaul of these three parts. 1. Small repair (1) Check the belt tension level, if not suited to be adjusted. (2) fix the anchor bolts, check the angle of the blades is correct. 2. The content of repair include minor repairs, as well as check the coupling, alarm, gear box gear in these areas, but also for filling oil lubrication. 3. The overhaul includes the repair content, but also on the blade, gearbox, wearing parts, bearings, shaft, transmission, steering system, check for the replacement, should be replaced. Finally, we need to fan embalmed. Second, the axial flow fan 1. Prepare the test before the test (1) The unit has been completed maintenance, and quality to meet the requirements. (2) the site has been cleaned, the machine has plus a good oil, electrical instruments driving conditions have been met. 2. The test (1) start the fan, the fan rotation direction of view is correct quote Nanchang fans, the fan is operating smoothly Nanchang fans wholesale, without exception, the motor current is within a predetermined range. (2) running for an hour, checking gear oil temperature is not greater than 80 ℃, the temperature rise of no more than 40 ℃, bearing vibration is not greater than 6.3mm / s, if not normal, you should find out the reasons, to resolve. (3) test, the position of each part to be correct, fasteners should be tightened, there should be no leakage sealing, can be considered a test qualified.
