Solution of high temperature in SKF linear bearing
(1) , bearings to keep their working environment clean.
Even if the eyes can not see the fine dust, will bring adverse effects on the linear bearing. Therefore, keep the surroundings clean so that dust will not invade the SKF Bearing.
(2) , use with care.
Bearing in use gives a strong impact, there will be a scar and indentation, the cause of the accident. In serious cases, cracks and fractures must be paid attention to.Solution of high temperature in SKF linear bearing
(3) , use appropriate operating tools.
Avoid existing tools instead, you must use the right tools.Solution of high temperature in SKF linear bearing
(4) , pay attention to bearing corrosion.Solution of high temperature in SKF linear bearing
When the bearing runs, the hands will rust because of sweat. Pay attention to clean hands and wear gloves as much as possible.
There are many causes of SKF Bearing Failure. All the design and manufacturing process factors and the influence of linear bearing failure are not easy to determine. Under normal circumstances, in general, you can consider and analyze factors and internal factors.Solution of high temperature in SKF linear bearing
When the bearing temperature rises, first judge whether there is misoperation. If it does rise, the following treatment shall be carried out:
(1). Check whether the cooling water pressure, water flow and pipeline system are normal. If the water pressure is low, the filter may be blocked and cannot be handled in time, it can be shut down for treatment. When it is confirmed that it can work, it can be put into use.
(2). Check the oil pressure of the governor. If the oil pressure is low, the cooling water hydraulic valve may be closed.
(3). Check whether SKF Bearing has abnormal sound and whether bearing swing is abnormal.
(4). Take an oil sample to observe whether the oil color has changed, and test to see whether it has deteriorated. If the deterioration is confirmed, stop the machine and replace it with new oil.
(5). Check whether the oil level of the oil gauge is normal. If not, check whether the oil drain valve of the oil tank is tightly closed. If it has been closed tightly, oil shall be added. If it is oil leakage from the sealant pad, it shall be shut down for treatment.
When we use linear bearings, if we find that the temperature is very high, we should stop the operation of the equipment quickly, find out the cause, and deal with it according to the solutions provided above.
However, the solutions may be different due to the different causes of SKF Bearing heating, so we should treat it on a case by case basis and complete it with the help of technicians.
The normal sound of bearing operation should be uniform, stable and not harsh, while the abnormal sound of bearing operation has various intermittent, impact or harsh sounds. First, get used to the normal ina shaft rotation sound, and then you can grasp and judge the abnormal bearing operation sound.
Then, through the accumulation of practical experience, you can further analyze what kind of abnormal sound corresponds to what kind of bearing abnormal phenomenon. There are many kinds of abnormal sounds of inlaid solid lubricated bearings, which are difficult to speak and mainly rely on experience.
Bearing maintenance: bearing cleaning: when disassembling the lower bearing for maintenance, first record the appearance of the bearing, confirm the residual amount of smoothing agent, and wash the bearing after sampling the smoothing agent for inspection. As a cleaning agent, gasoline and kerosene are commonly used.
The cleaning of the removed bearing is divided into coarse cleaning and fine cleaning. They are placed in the container respectively. First, put the metal mesh bottom so that the INA Bearing does not directly contact the dirt of the container. During rough cleaning, if the bearing rotates with dirt, it will damage the rolling surface of the embedded solid lubrication bearing, which should be paid attention to. In the coarse cleaning oil, use the brush to remove the smooth grease and adhesion. After it is roughly clean, turn to fine cleaning.
