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 preventing protection. Early detection of bearing damage to prevent equipment from stopping due to bearing damage caused by non-schema protection time.
But not everything and all of them are equipped with this leading instrument. In this case, it is necessary for the operator or protection engineer of the machine to be highly vigilant about the "bug signal" of the bearing; for example, noise; temperature and oscillation. "Listen" "Contact" and "Investigation" are three important elements. The following views can be used as your reference.
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, it will reduce the bearing life. The causes of high temperature bearings include: smooth lack or overheating; magazines in smoothing agents; excessive load; bearing damage; lack of voids; and high temperature conflicts in oil seals.
Therefore, it is necessary to continuously monitor the bearing temperature; whether it is measuring the bearing itself or other important parts. If the working conditions are not changed; any temperature changes can indicate that the problem has occurred.
The timing measurement of the bearing temperature can be measured by means of a thermometer; the bearing temperature can be accurately measured and displayed in degrees Celsius.
Importance of the bearing; meaning 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 naturally rise in temperature after smoothing or smoothing and continue for one or two days.
