Bush scrape preceded axis rotor axis and the housing correction, while adjusting the gap and the gap between the rear side of the shaft hole impeller shaft and housing between the air inlet to conform equipment technical documents regulations. Spindle and bearing assembly Linfen centrifugal fan, the device should be required technical documents to be checked. Should be maintained between 0.03 to 0.04 mm in the bearing cap and bearing interference (measure the outside diameter of the bearing and the bearing inner diameter). Centrifugal fan casing assembly, should be the basis of the rotor axis alignment cabinet position and within the scope of the impeller inlet and the housing inlet axial and radial clearance between the high-speed ports to the device specified in the technical documentation while checking the anchor bolts are tightened. The gap value technical documents such as equipment not specified when Fenyang centrifugal fans, axial clearance should generally 1/100 impeller diameter, radial clearance should be evenly distributed, its value should be the impeller diameter of 1.5 / 1000 2-3 / 1000 (small diameter by whichever is greater). Seeks to adjust the gap smaller value, in order to improve efficiency of the fan. Centrifugal fan design to achieve high efficiency and other requirements, we must first consider more important to choose the following programs. ① vane type reasonable choice a. Obtained before the pressure from the gas to see the maximum blade centrifugal fan, radial blade a little time after the minimum to the blades. b. From an efficiency standpoint, the highest after the blade, radial blade centrifugal fan Yangquan center forward blade minimum. C. From the structure size, the flow rate and speed constant, to reach the same pressure premise, prior to the smallest diameter of the impeller, and radial impellers Suppliers lesser diameter, the maximum diameter of the impeller after. d. From the process point of view, the simplest straight blade manufacturing.
