About bearing temperature control and vibration technology how much do you know?

Bearing in the process of running, always inevitably produce certain vibration. Longer duration of use, bearing vibration is sensitive to bearing damage, such as peeling, indentation, rust, cracks, wear, etc. , these will be reflected in the bearing vibration measuring. Normally we can use special bearing vibration meter can measure the size of the vibration. We mainly use the measured frequency to deduce the bearing to the size of the specific situation. Measured value will be for the use of the bearing conditions or sensor installation location, etc. Therefore, we need to analyze the measurement value of each machine in advance after comparing criterion is determined. In the process of bearing running at the same time, the temperature is also one of the more important is the parameter. The temperature of the bearing as its operation began to slowly rise, usually 1 ~ 2 hours will reach a steady state. And the normal temperature of bearing will be as the machine heat capacity, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, then must stop running, and take the necessary precautions. That is to say, in the process of bearing work, we need to close attention to the change of its working temperature. Using thermal device can monitor the temperature of the bearing work at any time, and realize e. automatic alarm when the temperature exceeds or stop to prevent the shaft accidents. Commonly used high temperature often said bearing is in abnormal situation. In fact, in order to ensure the bearing work effectively, its working temperature is continuity test is necessary. Whether measured bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred.
