Axial fans and centrifugal fan of axial fan of the type of discrimination 1. flow, pressure head small Nanchang fans, and small centrifugal fan flow, pressure headaches. 2. In terms of air flow, axial fan airflow direction is perpendicular to the direction of rotation of the blade, and the centrifugal fan is cut in the direction of rotation of the blade. 3. If the amount of wind, air pressure under the same circumstances, the power consumption is higher than the centrifugal fan axial fans, but the noise centrifugal fan is running lower than axial fans. 4. axial fans used in the context of more fire ventilation fan wholesale Nanchang, and centrifugal fan is used for high-end buildings. 5. The axial fan blade diameter, it is subject to its limitations shell diameter, while the centrifugal fan is not the issue. 6. In terms of amount of wind pressure, centrifugal fan requires wider adaptability. 7. The centrifugal fan duct flow can be changed within the media, and axial fan can not. 8. The centrifugal fan installation is complex, and axial fans will have much simpler. 9. The centrifugal fan motor is connected via the shaft, so it is not within the fan. The axial fan motor is in the fan. Nanchang Jin Xiangyun plant cooling ventilation equipment is a professional sales suction fan, cooling water curtain, chiller suppliers.

The main cause of the fan rattling has these, as follows: (1) The fan shaft and motor shaft is not concentric; (2) based on the stiffness of the overall stent or inadequate; (3) bolts, rivets loose, or the impeller deformed; with the impeller shaft and the shaft hole between the plate (4) loosening; (5) there is dust or dirt on the blade or worn or deformed, so that the rotor becomes unbalanced; (6) Fan inlet and outlet piping is not installed, the resonance phenomenon occurs; (7) of the bearing temperature is too high, or the bearing box severe vibration occurs; (8) the quality of grease, but off, or interspersed with impurities, or degenerate; (9 ) Rolling friction occurs between the inner and outer rings, or curved, damage; (10) or the inlet housing and the impeller friction; (11) the motor current is too large, or the temperature is too high; (12) the fan starts , adjust the door or the outlet duct gate not closed tightly; (13) motor input voltage is too low, a power single-phase power outage; (14) transport medium temperature is too low, so that the motor is overloaded; (15) Systems system can not match the performance of the fan so that the fan is at a low pressure flow area, you can not run well.

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, 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 should be properly Nanchang suction fan, fasteners should be tightened, there should be no leakage sealing, can be considered a test qualified.
