Through the combination of bearing failure and degradation of the performance status of parameters to determine and predict the reliability and performance of IKO bearings, the site of the abnormal situation, causes and the degree of risk identification and judgment, and decide to repair and improve the technical methods.
Therefore, the bearing fault diagnosis technology is not a simple fault detection (or monitoring) technology, nor is it a simple point inspection instrumentation. Correctly, quickly and effectively to signal acquisition, data processing, manual or automatic identification and judgment. In order to determine the repair cycle of science, but also various types of failure mechanism, fatigue, wear life, the necessary tests and estimates. Determine the extent of bearing damage in use can be one, two touch, three observation to determine.
1, observed: Bearing good lubrication and no debris and moisture into the oil seal that IKO bearings, no wear, if you open the box of the original IKO bearings should visually check the bearing and regular inspection seal. Check to ensure they are sufficient to prevent the hot liquid, corrosive liquids and gases penetrate along the axis of bearing close to the situation of the bearing at the oil seal, oil seal Ruoyi damage should be replaced as soon as possible. Check the automatic lubrication system to ensure that oil or grease into the combination of bearing and ensure the correct dosage at the same time check whether the lubricant color or black, if there is this case usually means that the lubricant containing the impurities, in which case the bearing use is harmful.
2, listen to: the use of hearing to identify the irregular operation, a very common method. With a screwdriver or electronic stethoscope to detect a streamlined non-normal noise is a frequently used way of operating and maintenance personnel with some experience. If the bearing is good running condition will be issued a low hum sound, such as bearings issued a sharp hissing sound, squeak, and other irregular sounds, it is possible that IKO bearings have been in a bad operation state.
3, touch: the high temperature is often said that IKO bearings have been in the unusual situation, the high temperature within the bearing lubricant is harmful, but bearing certain times of the high temperature caused by the combination of bearing lubricant, bearings in more than 120 ℃ The temperature of the long-term operation will reduce bearing life. Reasons bearing high temperature caused by a lack of lubricant or excessive lubrication, the impurities in the lubricant, the load is too large, bearing damage, lack of clearance and oil seals engage friction.
In normal circumstances, bearing in just lubrication or lubrication after the temperature rise will be natural and will last one to two days.
