During the operation of bearings, certain vibration is always inevitable. With the extension of service time, bearing vibration will be very sensitive to bearing damage, such as peeling, indentation, corrosion, cracks, wear, etc., which will be reflected in the bearing vibration measurement. Generally, we can use a special bearing vibration meter to measure the vibration.
We mainly use the measured frequency to infer the specific situation of the bearing. The measured value will vary according to the service 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, the temperature of the bearing is also an important parameter during its operation.
The temperature of the bearing usually rises slowly with its operation, and it will reach a stable state after 1~2 hours. The normal temperature of the bearing will vary with the thermal capacity, heat dissipation, speed and load of the machine. If the lubrication and installation parts are appropriate, the bearing temperature will rise sharply, and abnormal high temperature will occur. At this time, the operation must be stopped and necessary preventive measures must be taken.
In other words, during the working process of the bearing, we need to pay close attention to the change of its working temperature. Using the thermal sensor, the temperature of the bearing can be monitored at any time, and the automatic alarm or stop when the temperature exceeds the specified value can be realized to prevent the occurrence of combustion shaft accidents. Generally, high temperature often indicates that the bearing has been in an abnormal condition.
In fact, in order to ensure the efficient operation of the bearing, it is very necessary to detect its working temperature continuously. Whether it is measuring the bearing itself or other important parts. If the operating conditions remain unchanged, any temperature change can indicate that a fault has occurred.
