The anti-corrosion centrifugal fan runs at a fast speed during the whole process of application. It is very easy to cause the rolling bearing temperature to be too high. If the rolling bearing temperature is too high, it is very easy to cause abnormalities in the application of the centrifugal fan. If it is more serious, the centrifugal fan will not work. Therefore, you must find the cause and deal with this situation immediately. Let's analyze the reasons that cause the rolling bearing temperature to be too high.
1. Poor gloss, oil growth or less oil.
2. The installation quality of the rolling bearing is not good, the torque is too large, and the working backlash is small.
3. The quality of the rolling bearing itself is not good, such as the initial backlash cannot be specified, or the roller bearing or the ring is defective.
4. The anti-corrosion centrifugal fan oscillates the large rolling bearing to accept the impact load and so on.
5. Inadequate water cooling of rolling bearings, natural ventilation or lack of water flow, etc.
For anticorrosive centrifugal fans with relatively high speed and high working temperature, because of the tightening of the anchor bolts connecting the bearing and the top cover under normal conditions, no torque is required to move the hand for tightening. The tightening force is often too large, and then The working backlash is reduced, and the rolling bearing becomes hot and the temperature is high; perhaps due to the small working backlash of the rolling bearing, the self-sufficient rolling bearing cannot move actively along with the thermal expansion of the shaft, so that the radial load received by the two rolling bearings is too large, causing The rolling bearing is hot and damaged.
Therefore, when applying anti-corrosion centrifugal fans, you should pay attention to selecting suitable rolling bearings for installation and application, so that they can assist in the operation of the equipment. Incorrect applications always bear the burden on the operation of the equipment and cause the temperature to rise. Pay attention to the proper installation method of rolling bearings.
