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, equipment and technology should be required 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). Corrosion centrifugal fan with low noise centrifugal fan casing assembly, should be the basis of the rotor axis alignment cabinet position and the air inlet of the impeller housing inlet axial and radial gap between the high-speed port to the device technology within the range of documents, as well as checking the anchor bolts are tightened. The gap value technical documents such as equipment not specified, generally axial clearance should be 1/100 impeller diameter, radial clearance should be evenly distributed, its value should be the impeller diameter of 1.5 / 1000 2-3 / 1000 (OD small ones whichever is greater). Seeks to adjust the gap value smaller FRP centrifugal fan manufacturers to improve efficiency of the fan. Tool steel pipe centrifugal fan is a fan with a long history, has been widely used in industry and in life, and is a kind of centrifugal fan in the traditional fan establish scientific and technological content based on a relatively high fan types. Since it is a high-tech products, in some respects than the old-fashioned fan has advantages. Centrifugal fans see this advantage mainly constructed from various parts of this fan, the first centrifugal fan casing, which is the main basis for judging the old fans and the new fans. This new fan casing is made of sheet steel, more rugged and reliable, can be divided into the overall style and semi-open. Now people are basically using a semi-open centrifugal fan.
