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 centrifugal fan, so not too tight with limited impact on the bearing clearance for higher speeds, I make a high temperature centrifugal fan, due to bearing and By tightening the general superstructure coupling bolts are not using the torque wrench Leshan impeller centrifugal fan, in order to prevent loose, tighten the force is often too large, so that! one for clearance smaller Zigong centrifugal fan models, thus causing the bearing fever caused by temperature high; or because the bearing clearance small tour, mountain-side bearing can lead to self 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. Centrifugal fan in the use of the process, pressure and flow generated is an important factor affecting its stability, so we use centrifugal fan when we must, look at the pressure and flow changes it produces, usually lying Meishan centrifugal fans, centrifugal fans with flow will vary the rotational speed of change, the more broad range of choice if the pressure, then the choice will flow to meet the needs of users through speed, due to the impeller centrifugal fan does not produce friction in the body running, then it does not require lubrication, it will not drain out of gas oil. Thus, smooth and almost every component of centrifugal fan has a direct relationship, which requires the user to use a centrifugal blower process to guarantee the effectiveness of each component for the stability of the basic protection provided fans .
