By the end of the year, many users of high and low temperature test chambers will choose to maintain equipment for one year. The compressor is one of the essential maintenance items for high and low temperature test chambers, but do you know that there are still compressors? A component also needs our special attention, that is, the bearing, how to maintain the compressor motor bearing, directly affects the service life of the bearing, sometimes we can judge the use of the compressor by the sound. 1. When the motor is running, a screwdriver can be used, the tip is placed on the bearing cover, and the ear is close to the wooden handle of the screwdriver to monitor the sound of the bearing. For example, the rolling element has a vague rolling sound in the inner and outer rings, and the sound is monotonous and uniform, which makes people feel relaxed, indicating that the bearing is good and the motor is running normally. If you hear an abnormal sound, you should analyze the cause and deal with it. 2. The rolling body has an irregular impact sound, indicating that the bearing has individual rolling elements broken and needs to be replaced. 3, approximating the whistle of the whistle, mixed with the rolling sound of the rolling element, indicating that the bearing lacks grease or improper selection of lubricating oil, need to add clean lubricating oil or replace the appropriate lubricating oil. 4. I heard obvious rolling and rolling sounds of the rolling elements, indicating that the bearing clearance is too large or severely worn and needs to be replaced.
