The bearing of the Reitz fan is the same as the impeller of the Reitz fan. Its role in use cannot be ignored. However, there are always many problems in the use of the bearing. Some bearing failures are actually formed by many small details. The bearing of the Reitz fan is the same as the impeller of the Reitz fan, and its role in use cannot be ignored. However, there are always many problems in the use of the bearing. The failure of some bearings is actually a lot of small details. Formed, such as the bearing wear problem of the Reitz fan, the temperature rise problem, etc., these problems will affect the use of the bearing, so solving these problems is the user's current important thing, especially the problem of rising bearing temperature is even more urgent solve. Ruitian Electromechanical "target=_blank> Electromechanical to see with you all the reasons for the excessive temperature of the bearing?
The relationship between the lubrication system and the bearings is very close. The purpose of lubrication with the Reitz fan is to create friction between the solid and the liquid without causing friction between the static and dynamic parts. If the amount of lubricating oil is insufficient or the quality is poor, the static and dynamic parts will directly rub the heat, or the heat can not be carried away by the lubricating oil, and the high-pressure fan bearing temperature will rise. Therefore, the user must pay attention to the lubrication system of the fan and protect it as much as possible.
In addition to the lubrication system, the bearing itself can cause a lot of problems. If the quality of the Reitz fan bearing is very poor, then the bearing in the use of the fan must not be able to achieve the maximum effect. Rolling bearing assembly quality is not good, such as the tightness of the inner sleeve and the shaft is not enough, the gap between the outer sleeve and the bearing housing is too large or too small will cause the temperature to rise. The sealing felt is too tight and hot; the high-pressure fan bearing vibration is too large to withstand the impact load, which seriously affects the stability of the lubricating oil film; the high-pressure fan bearing cooling water is insufficient or interrupted, affecting the heat out, and the bearing temperature is increased; the rolling bearing rolling Deformation, cracking, spalling, etc., will destroy the stability and uniformity of the oil film, and the surface will cause the bearing to heat up.
These are some of the small details of the use of the Reitz fan, but it is precisely because these small details are not handled properly that the problem of overheating will occur. If the user can notice these problems, the bearings of the Reitz fan The problem will definitely be solved very well.
Although many places and many equipments cannot leave the bearing, the bearing will generate a large amount of temperature due to friction during use. For a long time, the bearing problem is slowly exposed, or the bearing is broken, or the bearing is deformed. In fact, these problems are related to the excessive temperature of the bearing. We take the bearing of the wear-resistant fan as an example to find some ways to solve the problem that the temperature of the fan bearing is too high.
In fact, the wear-resistant fan needs to use the same bearing as other types of fans. Therefore, the bearing temperature is too high. The most likely cause of this phenomenon is that the inlet and outlet pipe gates are not closed when the fan is driving. In this way, the spindle speed easily exceeds the rated value, and the motor input voltage is low or the power supply is single-phase power-off, which is affected by the severe vibration of the bearing housing, the viscous material contained in the input gas, the ambient temperature is too low, the specific gravity is too large, etc. Is the cause.
In addition to these reasons, the vibration of the Reitz wind enclosure, poor quality of the lubricant, or deterioration, or the entry of dust, or too little lubricant, are also the cause of excessive fan bearing temperature, There are some reasons that are not very common, but it has also appeared in the fans used by some users. The tightening force of the bearing box cover and the seat bolt is too large or too small, the shaft and the rolling bearing are installed obliquely, and the front and rear bearings are not concentric. Fan rolling bearing damage or shaft bending, these reasons if the user does not pay attention to the use of the fan will cause the fan bearing temperature to rise.
The key to solving this problem lies in the user's professional maintenance and maintenance in the use of the wear-resistant fan. It should be kept by a special person and used by a person to regularly remove impurities such as dust and dirt inside the fan and prevent rust. After the maintenance, the lubricant should be replaced. Under normal circumstances, the lubricant should be replaced according to the actual situation. Through regular or irregular maintenance, the frequency of failures will be reduced, and the life of the Reitz fan will be extended, which will improve the overall performance of the fans such as axial fans. Although the problem of excessive temperature of the bearing cannot be completely solved fundamentally, as long as the user has made the position maintenance of the Reitz fan, the temperature of the fan bearing can be greatly reduced, and the service life of the bearing can be prolonged.
