Viewing the condition of the machine at work and preparing a complete view is now more and more serious. In the meantime, the bearing is the focus; because it is the most important rotating part of all machines. Condition monitoring is an important part of avoiding protection. The operator or protection engineer of the machine is highly vigilant about the “bug signal†of the bearing; for example, noise, temperature and oscillation. “Listeningâ€, “contact†and “investigation†are three important elements. The following is provided by the bearing trading network. The point of view can be used as your reference. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. Investigate the bearing if it is outstandingly smooth and correct to isolate debris and moisture; it indicates that the oil seal should be free of wear; however; the best when opening the bearing housing; visually check the bearing and check the oil seal regularly; see the proximity bearing The oil seal is used to ensure that they are sufficient to prevent hot liquid or corrosive liquid or gas from entering the bearing along the axis. The retaining ring and labyrinth oil seal should be greased to ensure maximum protection. If the oil seal is worn, it should be replaced quickly. The function of the oil seal In addition to avoiding the magazine entering the bearing; another function is to stick the smoothing agent in the bearing housing. If there is oil leakage in the oil seal, you should immediately check whether the oil seal is worn or damaged or the oil plug is loose. The appearance of the oil leakage can also be caused by the bearing. The mixing surface of the box is loose or because of the excessive increase of the smoothing agent; the active smoothing system is checked to ensure the correct amount of increase; together, the smoothing agent can be discolored or blackened; if there is such an appearance; Smoothing agents are rich in magazines.
Second, listening to the use of hearing to identify irregular work is a very general approach. For example, using an electronic stethoscope to view the abnormal noise of a part is experienced by the operator. Bearings will be declared if they are in outstanding work conditions. Low humming sound. If a sharp voice is announced; voices and other irregular sounds; generally indicate that the bearing is in poor working condition. Sharp squeaking noise can be caused by improper smoothness. Inappropriate The bearing clearance can also form a metal sound. The dent on the outer ring of the bearing will cause oscillation; and a smooth and loud sound will be formed. If the knocking flaw is formed by the device, the noise will also occur; this noise will follow the bearing speed. The bump is different. If there is intermittent noise, it indicates that the roll can be damaged.
Third, the smoothness of the grease smooth bearing is the best in the program equipment stop time; and make up for the time. Clear the old grease together or the old grease through the drain plug. In the new oil should be given to the nozzle Scrub clean. If the bearing box does not have a device for the grease nipple; then open the bearing box cover or end cap to remove the old grease; then make up the same fresh grease.
4. The oil is smooth and a small amount of oil is taken as a sample and compared with fresh engine oil. If the sample looks like a cloud; then it can be mixed with water; it should be replaced. If the sample is darkened or thickened, then It can indicate that the oil is carbonized at the beginning. All the old oil should be replaced; if it is possible; use fresh oil to wash the bearings. The replacement of the oil should ensure that the oil type replaced is the same; and make up for the required oil level.
There is a more reliable way to resolve the oil condition; it is to analyze the sample; if the oil is contaminated, it should replace the oil seal or think about the filter.
5. Contact with high temperature often indicates that the bearing is in an abnormal condition. High temperature is also harmful to the smoothing agent in the bearing. Sometimes the bearing overheating can be attributed to the smoothing agent of the bearing; if the bearing works for a long time beyond the temperature of 125 degrees Celsius; The causes of high temperature bearings include: smooth lack or overheating; smoothing agent is rich in impurities; excessive load; bearing damage; lack of voids; and high temperature conflicts of oil seals, etc. It is necessary; whether it is measuring the bearing itself or other important parts. If it is not working conditions; any temperature changes can indicate that there is a problem.
The timing measurement of the bearing temperature can be based on the thermometer; it can accurately measure the bearing temperature and appear in degrees Celsius. The importance of the bearing; means that when it is damaged; it will form a stop of the equipment; therefore, the most suitable type of such a bearing should be equipped with a temperature detector. Under normal conditions; the bearing will have a natural temperature rise after smoothing or smoothing and continue for one or two days.
Proper device protection is an important factor in promoting the longest service life of bearings. It is necessary to pay attention to the cleanliness of bearings; the correctness of bearing selection and the selection of appropriate equipment and protection. Bearings need to avoid pollutants and moisture. Pollution; it is necessary to have the right device and smooth.
