JK67 fan

1, JK67 improved centrifugal blower adjust ventilator damper door structure, the original adjustment shaft bearing support at both ends of the blades are used, the structure of complex, long manufacturing cycle, high production costs, the specific structure shown in Figure 1. JK67 fan technician visits to customers, field research, the original structure has been simplified design, shown in Figure 2, where Fig. 2 instead of 1 1 1 to 3, 1 4 Figure 2 Figure 2 instead of ~ 6. After nearly six years in a variety of workplace applications tested and found to adjust the door of the new structure in the process of using the fan JK67 good results, can achieve the desired work purposes. Since 2008, the structure has been widely used on our products. The improved; 2, JK67 contrast fan structure (1) in the improved structure, the use of a sleeve bearing housing 2 instead of 1, 1 and 3 bearing cap bearing the original chart, and eliminating the Rolling 2 The bearing of the machining accuracy is relatively low, its structure is more easy to assemble. (2) the improved structure of the mandrel with a blade instead of the two original structures (blade) connecting shaft, blade and shaft with a number of plug weld in place a number of the original structure of the bolt connection, Under the premise of ensuring the connection strength as much as possible to simplify the assembly process. Through the above comparison JK67 fan structure, to ensure the original structure and function of the premise, because the shape of the new structural components to simplify, reduce the number, ease of processing and assembly, therefore, adopt a new structure significantly reduces the cost of production. 3 Conclusion For the next JK67 fan damper, improved structure fully meet the work requirements of the fan case, reduce product costs, reduce the quality of products is proven a viable structure improvement program for the F to promote the application of centrifugal fan.
