Therefore the design and manufacture of fan not only have a farreaching influence in the development of fan and the improvement of technology , but also the scheme that energy saving and carbon emission reduction , shock absorption in the design of fan can be extended to all areas of production. According to the different direction of the gas flow in the ventilator , it can be divided into the type of centrifugal, axial flow, oblique flow and cross flow . And according to the wide range of applications, as the centrifugal fan in mine, boiler, textile, building ventilation and other occasions are involved, the centrifugal fan have a far more application than document sums up the design of SFF type centrifugal ventilator transmitted by triangle tape in textile machinery. This design mainly covers the principle of operation , applicable occasions , development situation , the position of mechanical parts and so on . As well as analyses the design of the circular arc curved blade and the method of spiral case of the drawing in a small square . Taking into account the speed of fan is not high and acpanied by shock , the bearing seats are lubricated by grease lubrication structure . What’s more , it takes the action that installing the shock absorber bracket in the whole design .
