In the last episode, it is said that we can accurately analyze the faults of gear breaking and gear wear of the reducer through the "micro special fault diagnosis multi-dimensional analysis system".

Today's Xiaobian brings you:

Multidimensional analysis system for micro and special fault diagnosis

Diagnostic process and verification Part III



The following is a video illustration:


Test for bearing fault diagnosis-1

This time, two bearing faults on the bearing test bench were tested blindly. In the case that it is unknown which bearing has any fault, the bearing is analyzed through the diagnosis system, and the bearing is disassembled to verify the correctness of the conclusion.

First, install the vibration sensors on the supports of the two bearings, and start the test bench equipment.

Through the wt-msam integrated data acquisition control module, the vibration data of the two bearings are collected in real time. After the diagnosis system runs, the vibration frequency of the two bearings can be seen and the obvious difference can be seen. Generally speaking, the analysis can be started about 10 minutes after data collection.

Click "start analysis" to enter the diagnostic analysis interface, and the system starts big data calculation. Microtech has developed a series of algorithm toolsets for complex fault comprehensive spectrum, and automatically generates a diagnosis report when the operation is completed.

We can see in the diagnosis report that the bearing is normal, the failure probability is 0%, and the failure level is a. The outer ring of bearing II is faulty, with a failure probability of 85% and a failure level of B3.

In the "detection conclusion" column, the fault description of bearings at different measurement points is given and the implementation suggestions are given. In the conclusion of this analysis, it is clearly suggested to arrange maintenance for bearing II as soon as possible.

Here the process of bearing fault diagnosis and analysis is over!

Retain the diagnosis results and start disassembling the faulty bearing II. Open the protective cover, disassemble the bearing bracket and take out the bearing for inspection.

After careful troubleshooting, the fault of bearing outer ring was found, and the diagnosis report was verified to be consistent with the conclusion. The system accurately analyzes the bearing fault.

We have tested and verified the effectiveness and accuracy of the "micro special fault diagnosis multi-dimensional analysis system" with practice!



Test for bearing fault diagnosis-2


In the first section, we accurately diagnosed the fault of the bearing outer ring. Next, we will diagnose the fault of the bearing in the second section.

This time, two bearing faults on the bearing test bench were still tested blindly. In the case that the reducer has no fault and the fault type is unknown, the bearing is analyzed through the diagnosis system, and the conclusion is drawn, and then the reducer is disassembled to verify the correctness of the conclusion.

After the test bench is started, the vibration data of the two bearings are collected in real time through the wt-msam integrated data acquisition control module.

Start data collection, and start analysis after about 10 minutes.

We can see in the diagnosis report that the bearing is normal, the failure probability is 0%, and the failure level is a. The inner ring of bearing II has a fault, with a fault probability of 75% and a fault grade of B3. In the "detection conclusion" column, the fault description of bearings at different measurement points is given and the implementation suggestions are given. In the conclusion of this analysis, it is clearly suggested to arrange maintenance for bearing II as soon as possible.

Here, the process of bearing fault diagnosis and analysis in Section 2 is over!

Next, we will retain the diagnosis results and disassemble the faulty bearing II for verification. Open the protective cover, disassemble the bearing bracket and take out the bearing for inspection.

After careful troubleshooting, the fault of bearing outer ring was found, which was consistent with the conclusion of the diagnosis report. The system accurately analyzes the bearing fault.

We once again tested and verified the effectiveness and accuracy of the "micro special fault diagnosis multi-dimensional analysis system" for bearing fault diagnosis with practice!
