1. Listening: A very common method of using auditory to identify irregular work. For example, using a screwdriver or an electronic stethoscope to detect a streamlined abnormal noise is a method often used by operators and repairers who must have experienced it. If the bearing is under excellent working conditions, it will announce a low humming sound; if SKF bearings announce sharp voices, hum and other irregular sounds; it may indicate that the imported bearings are now in poor condition. The work situation is over. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2, touch: high temperature often indicates that the imported bearing is now in an abnormal condition; high temperature is also harmful to the smoothing agent in the bearing; but the high temperature of the bearing is caused by the smoothing agent in the SKF bearing; if the bearing exceeds 120 °C The long-term work of the temperature will reduce the bearing life. The reason for the high temperature of the bearing is the lack of smoothing agent or smooth over-fire, the impurities in the smoothing agent are too rich, the load is too large, the bearing is damaged, the play is lacking, and the oil seal occurs. Under normal conditions; the bearing will have a natural temperature rise just after smoothing or smoothing and will continue for one to two days.
3. Investigation: If the bearing is outstandingly smooth and there is no debris and moisture entering; the bearing oil seal is not worn; if the original imported bearing housing is opened; the bearing should be visually inspected and the oil seal should be viewed regularly. The condition of the oil seal is to ensure that they are sufficient to prevent hot liquids, corrosive liquids and gases from entering the bearing along the axis; if the oil seal is damaged, it should be replaced quickly. Check the active smooth system to ensure oil or smooth grease enters the SKF bearing; and ensure correct Increase the amount together to see if the smoothing agent can change color or blacken; if this condition is generally indicated that the smoothing agent is rich in impurities; this condition is also harmful to the use of the bearing.
