During the operation of the bearing, a certain vibration is always inevitable. With the extension of use time, bearing vibration will be very sensitive to bearing damage, such as flaking, indentation, corrosion, cracks, wear, etc., which will be reflected in bearing vibration measurement. In general, we can use a special bearing vibration measuring instrument to measure the vibration
We mainly use the measured frequency to infer the specific condition of the bearing. The measured value will be different depending on the use conditions of the bearing or the installation position of the sensor. Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard. At the same time, during the operation of the bearing, its temperature is also a more important parameter.
The temperature of the bearing usually starts to rise slowly with its operation, and will reach a stable state after 1 to 2 hours. The normal temperature of the bearing will vary with the heat capacity, heat dissipation, speed and load of the machine. If the lubrication and installation parts are suitable, the bearing temperature will rise sharply and abnormally high temperature will appear. At this time, the operation must be stopped and necessary precautions must be taken.
That is to say, in the process of bearing work, we need to pay close attention to the change of its working temperature. The thermal sensor can be used to monitor the temperature of the bearing at any time, and to automatically alarm or stop when the temperature exceeds the specified value to prevent burning shaft accidents. The general use of high temperature often indicates that the bearing is already in an abnormal condition.
In fact, in order to ensure the efficient operation of the bearing, it is very necessary to continuously check the working temperature. Whether it is measuring the bearing itself or other important parts. If the operating conditions remain unchanged, any temperature change may indicate that a failure has occurred.
