Industrial Axial Fans Low Noise High Efficiency Rolling Bearing Cooling Ventilation Exhaust Fan

The industrial axial fans is a single stage fan. The rotor is composed of an impeller and a blade, with an integral rolling bearing box and a hydraulic blade regulating device. The main bearing and rolling bearing are placed in a ball iron box, which is installed in the lower half of the fan housing and fixed with bolts. Each end of the spindle is equipped with a supporting bearing to bear the axial force. The oil level of the main bearing box is shown by an oil level indicator outside the fan housing. The lubrication and cooling of the bearing is assisted by an external oil supply device, and the surrounding air is naturally ventilated through the gap between the housing and the bearing box to increase its cooling.
The impeller is welded structure, because the impeller weight is light, the moment of inertia is small. The centrifugal force of the blade and petiole assembly is transferred to the smaller bearing ring by the thrust bearing, and the whole set of static and dynamic balance of the impeller assembly is checked before leaving the factory.
When the fan is running, the blade installation Angle can be adjusted and maintained through the blade hydraulic adjustment device. The blade is mounted on the outer end of the petiole, and the mounting Angle of the blade can be adjusted and kept in a certain position by the adjusting rod and slider mounted in the petiole. The regulating rod and slider are pushed by the regulating plate, which is composed of a pushing plate and an regulating ring, and is connected with the hydraulic cylinder of the blade hydraulic regulating device.
