About This Product
■ Overview
・ This is a program that adds vibration measurement function to the multifunctional measurement system SA-A1.
・ It has a basic function of vibration measurement, and can be diagnosed and tendency management of industrial machinery.
・ Precision diagnosis can be performed using FFT analysis functions and envelope processing functions.
・ Evaluation using the ISO absolute value judgment function is possible.
-Since up to 4 acceleration pickups can be connected, it is possible to measure the same clock of horizontal two directions and vertical one or more.
■ Vibration gauge mode
・ Measure acceleration, speed, and displacement at the same time
・ Continuously saves vibration values and rotations for each 100 msec by the auto store function
・ The average amount of vibration is calculated by the specified measurement time
・ Filters can be set individually for each of the acceleration, speed, and displacement
■ Simple diagnosis
Regularly measure the magnitude of the vibration and determine whether it is normal or abnormal based on the judgment standard.
■ Standard mode (judgment function)
Each channel can be determined by setting two thresholds for either acceleration, speed, or displacement.
■ Precision diagnosis (FFT analysis function / envelope processing function)
Use the FFT analysis function and envelope processing (acceleration wrapping line processing) function to identify the cause of the abnormal cause, and identify the occurrence position.
Here are examples of analysis of vibration causes from three patterns.
・ Axis receiving abnormality (bearing)
・ Miss alignment
·Unbalance
■ Trend management (relative value judgment)
The measurement data of acceleration, speed, and displacements that are regularly measured and accumulated in the SX-A1VA can be output in a lump, and the tendency can be managed using a metal calculation software such as Excel. To understand the cause of the vibration that changes vibration, such as a rotating device, it is necessary to accumulate and manage measurement data. The standard value is determined from the accumulated measurement data, and the precautions and dangerous values are determined.
If you exceed the precautions, you will be more monitored, and a precision diagnosis will be performed if the risk is exceeded. Generally, in the vibration speed area, the precautionary value is 2 to 3 times that of the normal value, and the value is 2 to 3 times that of the precautionary value. We determine the vibration measurement site of the machine, the measurement direction, and the measurement cycle, and manage and manage graphs that write in chronological terms.
