Hope, will make the eye often. At the time of inspection equipment, inspection personnel should all eye and make full use of my eyes, from the appearance of the equipment run, run, drip, leak, by the location of the equipment and spare parts, color change, find whether the equipment in normal state. The prevention of accidents must run in your noses. To smell, to do ear, nose often. Inspection personnel should, make full use of his nose and ears, found that the smell of the equipment, the sound is abnormal, so as to find out the abnormal state of equipment, targeted treatment.

Hardworking groped disorderly touch of avoid by all means, cause wrong operation. Bearing inspection mainly through the following three ways: 'listen', 'touch' and 'observation' 1, listen to use hearing to identify irregular operation is a very common method. For example, with the aid of electronic stethoscope, mechanical needles to detect a certain part of abnormal noise is often the way of experienced staff use. If the bearing is in good operation condition have a low whine, if a sharp hiss sound, make sound, as well as other irregular usually said bearing in the operation condition of bad. 2, touch the high temperature often said bearing is in abnormal state. High temperature but is also harmful to within the bearing lubricant. Sometimes bearing overheating referrible bearing lubricant, if the bearing under the condition of high temperature operation for a long time, can reduce the service life of bearing, the causes of bearing high temperature are: insufficient lubrication or excessive lubrication, lubricants contains impurities, heavy load, bearing damage, inadequate clearance and high friction produced by the oil seal and so on. 3, observation bearing if get good lubrication and can guarantee the correct cut off impurities and moisture, that is to say, oil seal intact without any abrasion.
