So how to deal with ina bearing damage. If the bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidental and Ina High Temperature Bearing premature damage, which can not be resistant to use.
This early damage, as opposed to fatigue life, is the quality service limit called failure or accident. Most of them are caused by careless installation, use and lubrication, Ina High Temperature Bearing foreign matters invading from the outside, and insufficient research on the thermal effects of shafts and shells.
As for the damage state of high-temperature bearing, such as the clamping damage of roller bearing ring and retaining edge, these reasons can be considered as insufficient lubricant, unsuitable, defects of oil supply and drainage structure, invasion of foreign matters, bearing installation error and excessive deflection of shaft.
Therefore, only investigating the bearing damage, it is difficult to know the real cause of the damage. However, if we know the use machinery, service conditions, the structure around the bearing, Ina High Temperature Bearing understand the situation before and after the accident,
and investigate the damage state of the bearing and several causes, we can prevent the recurrence of similar accidents.
First of all, when we dismantle the INA Bearing for inspection, we should first make appearance Ina High Temperature Bearing records by photography and other methods.
In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the high-temperature bearing. The cleaning of bearings is divided into rough cleaning and fine cleaning, and a metal grid can be placed at the bottom of the container.
At this time, if the ina bearing is rotated in the oil, pay attention to the damage to the rolling surface due to foreign matters. During fine cleaning, rotate the bearing slowly in oil and carry out it carefully.
The commonly used cleaning agent is neutral water-free diesel oil or kerosene, and sometimes warm lye is used as needed. No matter what kind of cleaning agent is used, Ina High Temperature Bearing always filter it and keep it clean.
Proper material selection is still a factor that must be considered in bearing failure analysis. The main task of bearing failure analysis is to find out the main factors causing bearing failure according to a large number of background materials, analysis data and failure forms,
so as to put forward targeted improvement measures, prolong the service life of high-temperature Ina High Temperature Bearing bearing and avoid sudden early failure of INA Bearing.
According to the technical requirements of bearing installation, use, maintenance and repair, monitor and inspect the load, speed, working temperature, vibration, noise and lubrication conditions of INA Bearing in operation. If any abnormality is found, find out the cause immediately and adjust it to make it return to normal.
After the ina bearing is installed, in order to check whether the Ina High Temperature Bearing installation is correct, the operation inspection shall be carried out. Small machinery can be rotated by hand to confirm whether it rotates smoothly.
The inspection items include poor operation caused by foreign matters, scars and indentation, unstable torque caused by poor installation and poor processing of mounting base, excessive torque caused by too small clearance, installation error and sealing friction, etc. If there is no abnormality, the power operation can be started.
Power operation, starting from no-load and low speed, slowly increase to the rated operation under the specified conditions. During the test run, the inspection items are whether there is abnormal sound, temperature change of angular contact ball bearing,
lubricant leakage or discoloration, etc. If any abnormality is found, Ina High Temperature Bearing stop the operation immediately, check the machinery, and remove the bearing for inspection if necessary.
1. Keep the bearing lubrication clean
Before inspecting the INA Bearing, the surface of the bearing should be cleaned first, and then the oil seal of the bearing and its surrounding parts should be carefully inspected.
If there are bad symptoms, it must be replaced. The bad oil seal will cause damage, make the cloud shape of the angular contact ball bearing abnormal and cause the shutdown of the equipment.
2. Pay attention to covering exposed bearings
When inspecting ina bearings, do not expose the bearings to pollutants or moisture. If the work is interrupted, the machine shall be covered with oil paper, plastic sheet or similar materials. If it is possible to clean the naked bearing without disassembly, clean it with a brush coated with petroleum solvent,
and then wipe it dry with a piece of lint free cloth or blow it dry with compressed air (be careful not to start the rotation of the bearing assembly). Check the bearing track surface, retainer and beads with a small mirror and a probe similar to that used by dentists. Do not clean the sealed cover or dust-proof bearing;
Just wipe the outer surface. If the bearing is damaged, it needs to be replaced. The replacement of angular contact ball bearings during regular shutdown and maintenance is much more economical than the loss of sudden shutdown due to array bearing damage.
3. Check the lubricant of bearing
Lubricants are important not only for bearings, but also for all bearings. However, please note that the bearing should not add too much grease. Then replace the lubricant of INA Bearing. For angular contact ball bearings lubricated with engine oil, after draining the old engine oil,
if possible, refill fresh engine oil and let the machine rotate at low speed for a few minutes. Make the oil collect residual pollutants as much as possible, and then drain the oil. When replacing the grease of the bearing lubricated with grease,
the Joe remover used shall avoid the contact of cotton with any part of the bearing. Because these Ina High Temperature Bearing residual fibers may wedge between rolling parts and cause damage, especially in bearing applications.
The service life of ina bearing is closely related to manufacturing, assembly and use. It must be done well in each link in order to make the non-standard bearing in good operation state, so as to prolong the service life of angular contact ball bearing.
