It is increasingly important to look at the situation of the machine at work and prepare a complete inspection plan; in the meantime, the bearing is the main point; because it is the most important rotating part of all machines; situation monitoring is an important part of preventing protection; early The detection can prevent the equipment from stopping due to bearing damage caused by non-schema protection time.
Especially in important machines or in harsh environments, the bearings should be viewed frequently; the market has presented quite a number of monitoring systems and instruments; it is used to monitor the operation of bearings and equipment; most of these instruments are based on Oscillating measurement.
However, not all machines are equipped with leading instruments; in this case, it is necessary for the operator or protection engineer of the machine to be highly vigilant about the bearing [error signal]; for example, noise, temperature and oscillation.
listen:
Using auditory to identify irregular work is a very general approach; for example, using an electronic stethoscope to detect abnormal noise in a part is experienced by the operator. If the bearing is in an excellent working condition, it will be declared low. The humming sound; if a sharp voice, voice, and other irregular sounds are declared, it generally indicates that the bearing is in poor working condition.
Sharp 吱吱 noise can be caused by improper smoothness. Inappropriate bearing clearances can also form metal sounds. The dents on the outer ring of the bearing can cause oscillations; and form a smooth and loud sound; The resulting knocking flaw will also cause noise; this noise will be different with the unevenness of the bearing speed. If there is intermittent noise, it means that the rolling part can be damaged; this sound is attacked when the damaged appearance is smashed. The pressure expires; if there are pollutants in the bearing, it often causes a squeak; severe bearing damage will result in irregular and loud noise.
Bearing damage can of course be viewed by listening; but generally it is now necessary to replace the bearing immediately. Therefore, the better way is to use electronic condition monitoring equipment; pre-diagnose the working condition of the bearing.
Compared with the old method (use a wooden stick or screwdriver to the bearing housing; the other end is attached to the ear); using the leading instrument can more accurately predict the bearing situation.
