Choose a good centrifugal fans, the most important prerequisite to first understand you want to buy this centrifugal fan centrifugal fan Chongqing repair work environment, work in a different environment for dust, explosion, corrosion, etc. definitely need to choose a different the fan. In addition, a reasonable choice except to meet centrifugal fan flow and pressure requirements, but also consider the needs of the efficient operation of the fan, which is an important factor in choosing the fan. Fan Fan performance is based on a reasonable selection of representation Sichuan Axial centrifugal fan, fan performance is different, fan selection methods are also different. 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. Shanxi centrifugal fan structure, equipment and technology should be required to file check spindle and bearing assembly. 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 centrifugal fans, axial clearance should generally 1/100 impeller diameter, radial clearance should be evenly distributed, its value should be 1.5 / 1000 2-3 / 1000 impeller diameter ( small diameter by whichever is greater). Seeks to adjust the gap smaller value, in order to improve efficiency of the fan.
