NSK self-aligning ball bearing temperature on the influence of the solution - bearing knowledge

by:Waxing     2020-05-26
In the process of using NSK self-aligning ball bearing is easy to appear the phenomenon of temperature rise. NSK self-aligning ball bearing temperature, when the first determines whether the wrong operation, such as really rise, should do the following processing: 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. To check whether there is sound, imported bearing NSK self-aligning ball bearing and detection 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. NSK self-aligning ball bearing vibration of damage can be said to be quite sensitive, peeling, indentation, rust, crack and wear will reflect in the NSK self-aligning ball bearing vibration measuring. So, through the use of special bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values for NSK self-aligning ball bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. We went on to look at the influence of temperature on imported bearing, NSK self-aligning ball bearing in high temperature often is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes overheated bearings can be classified to the bearing lubricant. If NSK self-aligning ball bearing in the more than 125 ℃ temperature for a long time even move lower NSK self-aligning ball bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, NSK self-aligning ball bearing ring, clearance, high friction and oil seal and so on. So the continuity of NSK self-aligning ball bearing temperature monitoring is necessary, whether measured bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. NSK self-aligning ball bearing temperature measurement on a regular basis by using a thermometer, digital thermometer, for example, NSK self-aligning ball bearing can be accurately measuring temperature and the constant unit in accordance with ℃ or Fahrenheit temperature display. The importance of bearing, means that when the damage cause of equipment downtime, so this type of NSK self-aligning ball bearing should be equipped with best temperature probe.
