The air suspension fan is used for conveying fresh air and can be applied to different industries. It has unique advantages and plays a particularly important role in the use of the industry. However, there are many problems in the use process, for example, the temperature of the air suspension fan is too high. So, what are the main reasons for the high temperature of the air suspension fan? Next, I will tell you in detail:
Poor lubrication quality. The purpose of lubrication is to make the dynamic and static parts not directly contact to generate friction, but to form friction between solid and liquid. If the lubrication quantity is insufficient or the quality is poor, the dynamic and static parts will be heated by direct friction, or the heat cannot be taken away by lubrication, which will increase the bearing temperature of the air suspension blower;
2. Poor assembly quality of rolling bearings. If the tightening force between the inner sleeve and the shaft is not enough, the clearance between the outer sleeve and the bearing seat is too large or too small.
3. The sealing felt is too tight and hot;
4. The bearing of air suspension fan vibrates excessively and bears impact load, which seriously affects the stability of lubricating film;
5. The bearing cooling water of air suspension fan is insufficient or interrupted, which affects the carrying out of heat and increases the bearing temperature;
6. The bearing quality of air suspension fan is poor. Poor scraping and grinding quality of sliding bearing, poor contact between black and gold, or out of tire; Cracks, cracks and spalling on the rolling surface of the rolling bearing will damage the stability and uniformity of the oil film and make the bearing hot.
