A master data and comprehensive information database of the device, the meta-analysis
Optional four horizontal pump bearing vibration monitoring, adjustment, radial radial shaft pick up the value of information from the vertical and horizontal, miniature bearing point of the eight-point detection. Practice has proved that the eight identified peak / carpet to pick up a comprehensive collection and vibration velocity and acceleration values??, you can easily find the fault, while the horizontal radial pick Peak / carpet value, lower bearing area bearing the same value pick at. Due to the bearing shell motor fan cover to ensure that monitoring and calculation accuracy, you need to open a small hole on the cover, so that the sensor probe in direct contact with the bush. Joint monitoring process requires monitoring personnel to determine the direct observation, such as the accuracy of the suspect data, we need to do additional tests were compared. The data thus obtained will be more reliable.
Monitoring, such as rotating equipment specially shaped, large bearing support, monitoring points away from the axis perpendicular to the path is too long, then the value obtained may decay, should be aware of.
Second, high vibration, to assess the operating state of the bearing, and then identify the source of vibration shaker
When the vibration monitor to a higher value, should first determine the operating conditions, the bearing failure can lead to many disadvantages, while the bearing Supplier Of SKF Bearing http://www.skf-bearing-lk.com/engineering/. After a preliminary analysis of comparable bearings, confirm bearing no fault, again based on ST's assessment guide signs - 101 analyzer to observe the results (mainly fundamental frequency of vibration, the vibration frequency doubling of the three bar graphs and vibration values in), high-frequency vibrations of different heart, unbalanced, swing devices, coupled with the acquisition of vibration velocity and acceleration values ??and units trends degradation, a troubleshooting a point, and finally determine the fault point horizontal centrifugal pump system failure often meet a real talent loose screws, concentricity two differential shaft connecting pin or damaged gaskets, single pump or motor rotor imbalance caused by the same source of two resonance
Periodic vibration measurement is valid on the basis of the mechanical state management. Analysis of the main sources of regular monitoring of vibration data is applied to one of the best methods. In the implementation of the bearing vibration monitoring, but also need to collect the appropriate equipment operating parameters, one of which is the basis for diagnostic analysis.
