Design and selection of relevant knowledge impeller centrifugal fan, under different circumstances according to the actual needs of different types of centrifugal fan centrifugal fan, the increase in the number of impeller blades of the impeller can improve the theoretical pressure, because it can reduce the relative influence of eddy currents ( i.e. increasing K value). However, an increase in the number of blades, will increase the friction losses Taiyuan channel impeller fan, this loss will reduce the actual pressure blower and increased energy consumption. Thus, for each wheel, there is an optimum number of blades. Specifically determined how much the number of leaves, and sometimes need to be based on the designer's experience. According to China's current application of axial fans, Taiyuan, in Table 2, the choice of the recommended number of leaves. Centrifugal fan design requirements: meet the conditions required flow and pressure points should be in the vicinity of the maximum efficiency point; maximum efficiency value to be as large as possible, flat efficiency curve; stable to a wide range of pressure curve; simple structure Taiyuan fan axial fan price, technology is good; materials and accessories selection easy; there is sufficient strength, stiffness, job security can; stable operation, low noise; regulation performance, strong adaptability of work; the fan size as small, light weight; Operation and Maintenance convenient, easy disassembly transport. In some factories plant, due to dust particularly likely to affect the health of employees, this situation will allow some companies in the development by a number of constraints. After all of the staff caused harm to human health, the state does not allow such a situation occur naturally develop will be limited. And since such a centrifugal fan is developed, the development of these areas will not longer be restricted. Because the centrifugal fan can be a good area to make certain cleanliness improved, using centrifugal force way to make some of the dust through the process gave exhaust discharged. Not only play the role of ventilation and cooling, and more play an important role in a row dust. Therefore, this centrifugal fan will be greatly welcomed in the industry, the demand on the main market of industrial centrifugal fans consume this field. Not only is this product manufacturers prefer, and even the workers are extremely fond of this centrifugal fan, after all, have such a mechanical will be able to make the safety of their workers are effectively protected.
