One, FAG Bearing Vibration
FAG Bearing vibration of the bearing damage is very sensitive, such as peeling, creasing, corrosion, cracks, wear, etc. will be reflected in the measurement of vibration, FAG bearings, so, by using a special bearing vibration measurements (frequency analyzer, etc.) measure the size of vibration frequency can not be inferred by abnormal circumstances. The measured values ??due to conditions or sensor mounting position FAG bearings, etc., and therefore requires prior measurements of each machine to be determined after the analysis and comparison criteria.
Two, FAG Bearing temperature
FAG Bearing temperatures are generally bearing chamber outside temperature can be inferred that if the use of the hole can be measured directly, FAG bearing outer ring temperature, more suitable position.
Typically, FAG bearings with the bearing operating temperature slowly began to rise 1-2 hours after reaching steady state. FAG Bearings normal temperatures due to the heat capacity, heat capacity, speed and load of the machine and different. If lubrication, install the appropriate department, the bearing temperature will be rapid rise, there will be abnormally high, then you must stop running, take the necessary precautions.
Thermal sensors can be monitored at any time using the FAG Bearing operating temperature, and automatic alarm or stop to prevent burning shaft accident temperature exceeds a predetermined value.
High temperature frequently expressed in unusual circumstances. High temperature also harmful FAG bearings lubricant. Sometimes FAG bearings overheating can be attributed to the bearing lubricant. If FAG Bearing temperature over 125 ℃ even move to reduce long-term FAG bearings life. FAG Bearing temperature causes include: lack of lubrication or excessive lubrication, lubricant. Contains impurities, the load is too large, FAG bearings damaged ring, the gap enough and high friction seals and so on.
Therefore, continuous monitoring of FAG Bearing temperature is necessary, whether it is a measure of FAG bearings themselves or other important parts. If you are under the same operating conditions, any change in temperature may indicate a fault has occurred.
FAG Bearing temperature measurement by means of a regular thermometer, digital thermometer for example, can be accurately measured temperature and FAG bearings ℃ or Fahrenheit according to fixed units.
The importance of FAG bearings, which means when it is damaged, can cause equipment downtime, and therefore the best kind of FAG Bearing temperature detectors should be installed.
Under normal circumstances, FAG bearings in lubrication or re-lubrication after just have a natural rise in temperature and sustained one to two days.
