First, the shock of impact on KOYO bearings.
In normal use, the vibration of the bearing damage is very sensitive, peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the bearing vibration measurement. So, by using a special bearing vibration measurements (frequency analyzer, etc.) to measure the size of the vibration frequency can not be inferred by abnormal circumstances. The measured values ??due to sensor mounting position of use of the bearing or the like, and therefore measured values ??required for each machine for analysis and comparison of the determined criteria.
Second, the temperature on the bearing.
Often expressed by high temperature KOYO bearings in unusual circumstances. High temperature is also harmful to the bearing lubricant. Sometimes overheated bearing can be attributed to the bearing lubricant. If the bearing temperature over 125 ℃ even move to reduce long bearing life. Causes high temperature bearings include: lack of lubrication or excessive lubrication, lubricant. Contains impurities, the load is too large, the bearing ring damage, lack of space, and high-friction seals and so on.
KOYO bearings in the use of the process temperature is prone to the phenomenon. When the bearing temperature, first determine whether misuse, as indeed increased, should be handled as follows:
1 Check the cooling water pressure, flow and piping systems are normal. If water filter may be clogged down and can not handle, you can stop treatment, when it is confirmed to work, and then put into use.
2. Should check governor oil pressure, oil pressure may result if the cooling water hydraulic valves closed.
3 Check KOYO bearings Are there differences in tone and bearing swing detect whether there is an exception.
4 Take oil samples to observe whether there are changes in oil color, and conduct tests to see whether the deterioration. If confirmed deterioration should be replaced with new oil down.
5 Check the oil standard oil level is normal, if abnormal, check the tank drain valve is closed. If closed, should fill the oil, if it is sealed cushion oil leakage should stop processing.
Vibration damage to KOYO bearings can be quite sensitive, peeling, dents, rust, cracks, wear, etc. will be reflected in the bearing vibration measurement. So, by using a special bearing vibration measurements (frequency analyzer, etc.) to measure the size of the vibration frequency can not be inferred by abnormal circumstances. The measured values ??due to sensor mounting position of use of the bearing or the like, and therefore measured values ??required for each machine for analysis and comparison of the determined criteria.
We then look at the effect of temperature on the bearing, with high temperatures often expressed KOYO bearings in unusual circumstances. High temperature is also harmful to the bearing lubricant. Sometimes overheated bearing can be attributed to the bearing lubricant. If the temperature over 125 ℃ even move to reduce long bearing life. Causes high temperature bearings include: lack of lubrication or excessive lubrication, lubricant. Contains impurities, the load is too large, the bearing ring damage, lack of space, and high-friction seals and so on.
Thus, continuous monitoring of KOYO bearings temperature is necessary, the bearing itself is a measure of whether or other important parts. If you are under the same operating conditions, any change in temperature may indicate a fault has occurred.
KOYO bearings temperature measurement by means of a regular thermometer, such as digital thermometers, bearing temperature can be accurately measured and determined in accordance ℃ or Fahrenheit units. The importance of bearing, which means when it is damaged, can cause equipment downtime, and therefore the best type of bearing temperature detectors should be installed.
