Blower in the use of abnormal sound, to do a comprehensive inspection of the blower equipment, if it is found that the bearing abnormal sound caused by the problem, you have to analyze the cause of the abnormal, and then targeted treatment and maintenance, so why the blower bearing will emit abnormal sound?
The author makes a comprehensive analysis of the causes of abnormal sound and gives corresponding solutions.
Causes of abnormal sound of blower bearing
1, the bearing lubrication is insufficient, the blower bearing should be fully lubricated to operate normally, if the bearing is lack of lubrication, the direct performance is not smooth operation, abnormal friction leads to abnormal sound. Long time without lubrication will accelerate bearing wear, abnormal sound is more obvious.
2, bearing long-term use of serious wear. No matter how good the bearing has been used for a long time, there may be wear problems, which will increase the internal clearance and produce some abnormal sounds.
3. Foreign bodies are mixed. The working environment of the blower is not clean or is not cleaned in time, and foreign bodies such as dust and small stones may enter the equipment, which will increase the friction of the bearing and produce abnormal noise.
4, the bearing is not installed. When installing the blower bearing, if the installation is improper or the tightening torque is insufficient, it may cause abnormal noise when the bearing is working.
Blower bearing abnormal sound solution
1. Add lubrication
If the inspection is found to be caused by insufficient lubrication, an appropriate amount of lubricating oil can be applied to the blower bearing to help reduce bearing friction and wear and eliminate abnormal noise. When applying grease, it is necessary to apply evenly and add in strict accordance with technical standards. Excessive application of grease may cause overheating of bearings or oil leakage.
2, replace the bearing
Abnormal noise caused by serious bearing wear, or abnormal noise still not eliminated after applying grease, may need to be replaced with a new bearing. Here to check the bearing model, select the bearing that matches the original bearing model, install it in strict accordance with the operating procedures, if you are not clear, you can consult the bearing application engineer of VKUKEN, will recommend the appropriate bearing according to the type of blower.
3. Clean up foreign bodies
Blower bearings should also be cleaned regularly, otherwise foreign bodies are easy to cause noise. When cleaning foreign bodies, first turn off the blower power supply, remove the main shaft, bearings and other positions, carefully check the inside of the blower, bearing there is no foreign body residue, and then reassemble after cleaning.
If the above methods can not solve the problem of abnormal noise of the blower bearing, or are not sure how to deal with it, it is recommended to contact professional maintenance personnel to check and repair, they can diagnose the problem more accurately and provide effective solutions.
Conclusion
The general working environment of the blower is harsh and the operation time is long. In order to ensure the normal operation of the blower and extend the service life of the bearing, it is necessary to clean the blower regularly, remove foreign bodies, and check the lubrication of the bearing, and regularly apply grease to the bearing to prevent problems before they occur.
