Centrifugal blower fan is now gradually become a major industry in the broader application of a high-quality fan 4-72 high quality centrifugal fan, loved by the majority of users, then the main structure on the performance of the fans, we know about it, today we Details below: 1. inlet: made whole, mounted on the fan side, parallel to the axial cross-section shape of the curve, the gas can smoothly enter the impeller, and the loss is small. 2. Transmission Group: from the spindle, bearing housing, bearings, pulleys or coupling components. 3. Impeller: backward by 12 wing-shaped blade, curved front plate and the plate after plate components. With a cover or cast aluminum alloy, and the static and dynamic balance, good air 4-72 centrifugal fan performance, high efficiency and smooth operation. 4. Housing: made of two different types. No2.8 ~ 12 chassis made whole, can not be disassembled. Chassis No16 ~ 20 made three open separate into two and a half outside the plane except along the upper half was divided into two halves along the vertical centerline, with the bolt connection. The main structure is that these performance centrifugal fan, I believe we have some understanding, we must rational use of it, so that it is fully demonstrated performance, improve our work efficiency. The use of high-speed rotating centrifugal fan impeller gas accelerate and then decelerate, change the flow of a centrifugal fan 4-72 processors, so that kinetic energy into potential energy (pressure). In the single-stage centrifugal fan, the gas from entering the axial impeller centrifugal fan 4-72 authentic wholesale change to the gas flowing through the radial impeller, diffuser and then enter. In the diffuser, the gas flow direction changes caused by deceleration, the deceleration effect converting kinetic energy into pressure energy. Pressure increased mainly in impeller, diffuser second place in the process. In a multi-stage centrifugal fan, and reflux into the next impeller allows airflow, resulting in higher pressure. By centrifugal fan casing, spindle, impellers, bearings and electrical transmission and other components. Chassis: made of steel rugged and reliable, can be divided as a whole and semi-open, semi-open for easy maintenance. Impeller: the blade, curved front plate and the plate after plate components. Rotor: static balance and dynamic balance should be done to ensure smooth rotation, good performance. Transmission parts: a main shaft, bearing housing, bearing and pulley (or couplings) components. 4-72 centrifugal fan authentic wholesale, mass flat glass, steel, 4-72 centrifugal fan is provided by Wu Teng County Department 庄传平 fiberglass processing.
