Centrifugal fans are the most common mechanical ventilation, it works almost the same compressor and turbine, but due to the low gas flow rate, pressure changes little Sichuan Axial centrifugal fans, the specific volume of gas under normal circumstances do not change need to be considered, that the gas as an incompressible fluid handling. In the course of its installation, there are several steps to note the following with the gas-turbine with a look: 1, centrifugal fan site assembly, the cutting surface on the base should be properly protected, there should be no corrosion or operation When the base is placed horizontally on the basis of Shanxi centrifugal fan structure, application paired oblique horn leveling. 2, the bearing should be in close contact with the base centrifugal fan, vertical not horizontal should not exceed 0.2 / 1000, measured with a spirit level on the spindle horizontal bottom level should not exceed 0.3 / 1000, with a spirit level on the horizontal bearing carved surface measurements. For the selection of the bearing using the unit will change in accordance with the general equipment manufacturers of the original model with a rather large selection of note is appropriate, bearing improper selection. With the bearing and the bearing bore is generally used JS7 / BU 6, so not too tight fit, the impact of limited bearing clearance sale Inner centrifugal fans, for high speed, I make a high temperature centrifugal fan, the bearing Unscrew the seat and lid of the coupling bolts tight general case do not use the torque wrench, in order to prevent loose, tighten the force is often too large, so that the one for the clearance smaller, thus causing the bearing heat caused by high temperatures;! or because the bearing small clearance, resulting in self-Hill End bearings can not automatically move with the axis thermal expansion, so that both the bearing axial load is too large, causing heat damage to the bearing. Therefore, the production of replacement bearings, especially high temperature high speed centrifugal fan bearings, pay attention to the selection of bearings: ① attention to the speed limit is appropriate, ③ to choose the original clearance larger group C3 bearings.
