SKF full temperature in the working process of the cylindrical roller bearing lubrication maintenance way - bearing knowledge

When SKF bearing temperature, first of all determine whether false action, such as full cylindrical roller bearing temperature rise, really should do the following treatment: ( 1) 。 Check the cooling water pressure, water flow and pipeline system is normal. If water is likely to be lower filter blockage, cannot be handled in a timely manner, to stop treatment, when confirm can work, then put into use. ( 2) 。 Should be to check if the governor oil pressure, oil pressure is low can lead to cooling water hydraulic valve closed. ( 3) 。 Check for different sound, bearing and detect full cylindrical roller bearing degrees whether there are abnormal. ( 4) 。 Take oil whether there is a change of color, sample observation and test to see whether metamorphism. If confirm the degradation new oil should be replaced downtime. ( 5) 。 Check the oil standard oil level is normal, if abnormal, check that the sump oil discharge valve is shut. If the matter, should fill oil, if is the sealant mat permeability oil, should stop processing. When we use full cylindrical roller bearing, if it is found that the temperature is very high, is to stop the equipment running, and find out its reason, and provide solution for processing according to the above, but may be due to the reason of SKF bearing heating is different, so the solution is also different, so still have to treat, particular case is particular completed with the help of the technical staff. ( 1) Full cylindrical roller bearing is lubricated by grease, run after 1500 hours, should be replaced, grease filling the oil amount is too little or too much, because too much or too little will cause bearing grease fever, amount to general in the bearing should be 1/2 to 2/3 of the chamber volume. ( 2) For SKF bearing is lubricated by lubricating oil, oil should be added to the specified location. ( 3) Containers of lubricating oil or grease to clean, should be sealed at ordinary times, should not have dust, iron and other sundry, in order to avoid damage to the bearings. ( 4) Full of cylindrical roller bearings generally USES sodium base grease, this kind of ability is the feature of high temperature grease ( 125℃) , but easy to dissolve in the water, so can't use it for SKF bearing lubrication.
