Centrifugal blower and fan features and advantages Jan 18, 2018

Centrifugal blower and fan in the process of using its compact and beautiful appearance, good stability and easy installation and maintenance, centrifugal blower operation is very smooth, the entire device of the design of the impeller so that the axial force is reduced to a minimum and Efficient impeller, and the static and dynamic balance correction, the machine running smoothly, without any damping device, the bearing amplitude ≤ 0.04mm.

Centrifugal blower noise is low, the device is in the process of running without any of its mechanical friction, when used in the use of its reasonable blade-shaped line to the sound to a minimum. Centrifugal blower noise is high-frequency noise, as long as there are obstacles, can be noise, so the fan room almost no noise.

Centrifugal blower and fan bearings are lubricated with grease, the bearing life of more than three years. Fan does not generate oil and gas during operation. Special requirements fans, with molybdenum disulfide lithium grease lubrication bearings. Impeller with a special compound linear, reducing internal leakage, improve the volumetric efficiency.

Centrifugal blower and fan inlet valve to regulate flow, the outlet valve to regulate the pressure. Usually using a two-pole asynchronous motor, you can also use a four-pole motor drive. Depending on the user grid, different voltage motors can be used.

Centrifugal blower in addition to each level of import impeller impeller, the interstage and the housing at both ends with a labyrinth seal to prevent gas leaks. Exhaust bearing air-cooled and water-cooled two structures, as the impeller on the level of gas compression, resulting in the exhaust casing temperature is much higher than the intake casing. In the exhaust bearing air-cooled or water-cooled device to extend the bearing life.
