　　1. The impact of vibration on ZZ bearings.

　　In normal use, vibration is very sensitive to bearing damage, peeling, indentation, rust, cracks, wear, etc. will be reflected in the bearing vibration measurement. Therefore, by using a special bearing vibration measuring device (frequency analyzer, etc.), the magnitude of the vibration can be measured, and the specific abnormal situation cannot be inferred through the frequency division. The measured value is different due to the use condition of the bearing or the installation position of the sensor, so it is necessary to analyze and compare the measured value of each machine in advance to determine the judgment standard.

　　2. The influence of temperature on the bearing.

　　High temperature often indicates that the ZZ bearing has been in an abnormal condition. High temperature is also harmful to the lubricant of the bearing. Sometimes bearing overheating can be attributed to the lubricant of the bearing. Long-term continuous rotation of the bearing at a temperature exceeding 125°C will reduce the life of the bearing. Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants. Containing impurities, excessive load, bearing ring damage, insufficient clearance, and high friction caused by oil seals, etc.

　　In the process of using ZZ bearings, the temperature rise is easy to occur. When the bearing temperature rises, first judge whether it is misoperation, if it does rise, the following treatments should be done:

　　1. Check whether the cooling water pressure, water flow and piping system are normal. If the water pressure is low, it may be that the filter is clogged. If it cannot be processed in time, it can be shut down for processing. When it is confirmed that it can work, it can be put into use.

　　2. The oil pressure of the governor should be checked. If the oil pressure is low, it may cause the cooling water hydraulic valve to close.

　　3. Check whether the ZZ bearing has abnormal noise, and check whether the bearing swing is abnormal.

　　4. Take an oil sample to observe whether the oil color has changed, and conduct a laboratory test to see if it has deteriorated. If the deterioration is confirmed, the machine should be shut down and replaced with new oil.

　　5. Check whether the oil level is normal. If it is abnormal, check whether the drain valve of the oil tank is closed tightly. If it is closed tightly, oil should be refilled. If the sealant is leaking oil, it should be shut down for processing.

　　Vibration can be said to be quite sensitive to the damage of ZZ bearings, peeling, indentation, rust, cracks, wear, etc. will be reflected in the bearing vibration measurement. Therefore, by using a special bearing vibration measuring device (frequency analyzer, etc.), the magnitude of the vibration can be measured, and the specific abnormal situation cannot be inferred through the frequency division. The measured value is different due to the use condition of the bearing or the installation position of the sensor, so it is necessary to analyze and compare the measured value of each machine in advance to determine the judgment standard.

　　Let's take a look at the effect of temperature on the bearing. High temperature often indicates that the ZZ bearing is in an abnormal condition. High temperature is also harmful to the lubricant of the bearing. Sometimes bearing overheating can be attributed to the lubricant of the bearing. Long-term continuous rotation at temperatures exceeding 125°C will reduce bearing life. Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants. Containing impurities, excessive load, bearing ring damage, insufficient clearance, and high friction caused by oil seals, etc.

　　Therefore, it is necessary to continuously monitor the temperature of the ZZ bearing, whether it is measuring the bearing itself or other important parts. If the operating conditions remain unchanged, any temperature change can indicate that a malfunction has occurred.

　　ZZ bearing temperature can be measured regularly with the help of a thermometer, such as a digital thermometer, which can accurately measure the bearing temperature and display it in units of ℃ or Fahrenheit. The important bearing means that when it is damaged, it will cause the shutdown of the equipment, so it is best to install a temperature detector for this type of bearing.
