Vibration measurement and data analysis:

1.1 Vibration measurement

Vibration measurement is used to monitor the amplitude and frequency of vibrations of machines or components, in order to determine whether their operating status is normal. Vibration measurement can be applied in various fields, such as aviation, energy, manufacturing, etc. In the aviation field, vibration measurement can be used to monitor the vibration of aircraft engines and wings to ensure the safe operation of the aircraft. In the field of energy, vibration measurement can be used to monitor the vibration of equipment such as steam turbines, generators, and electric motors to ensure their normal operation. In the manufacturing industry, vibration measurement can be used to monitor the operating status of various machines to ensure the smooth progress of the production process.

1.2 Data Analysis

By collecting, organizing, and analyzing vibration data, useful information such as amplitude, frequency, phase, etc. can be extracted. By analyzing this information, the type, location, and severity of faults in the machine or component can be determined. In addition, by analyzing vibration data, the lifespan and performance degradation of machines or components can be predicted, providing a basis for predictive maintenance.

Identification and judgment of bearing damage:

2.1 Identification of Bearing Damage Types

Bearings are one of the most common components in machinery, and their types of damage include wear on the inner and outer raceways, fatigue peeling, and damage to the cage. By identifying the type of damage to the bearings, it is possible to determine whether the machine is operating normally.

2.2 Diagnostic Methods

The diagnostic methods for bearing damage include auscultation, tactile method, and instrumental diagnosis. Auscultation method is to determine whether the bearing is operating normally by listening to the sound of its operation; The tactile method is to determine the temperature, vibration, and wear of a bearing by touching its outer surface; The instrument diagnostic method measures the vibration and displacement parameters of bearings using instruments to determine whether they are operating normally.

Fault cause analysis:

3.1 Analysis of Mechanical Failure Causes

There are many reasons for mechanical failures, such as unreasonable design, imprecise manufacturing, incorrect assembly, poor lubrication, etc. By analyzingAnalyzing the causes of mechanical failures can identify the root cause of the problem and provide a basis for preventive maintenance.

3.2 Analysis of Bearing Failure Causes

The main causes of bearing failure include excessive load, fast speed, poor lubrication, etc. By analyzing the causes of bearing failures, the root cause of the problem can be identified, providing a basis for preventive maintenance.

Bearing performance degradation detection:

4.1 Performance degradation performance

The performance degradation of bearings mainly manifests as an increase in vibration and noise, a rise in temperature, and intensified wear. These behaviors can affect the normal operation of machines or components, and even lead to malfunctions.

4.2 Testing Methods

The detection methods for bearing performance degradation include vibration detection, temperature detection, wear detection, etc. The vibration detection method determines whether the performance of a bearing has degraded by measuring its vibration amplitude and frequency; The temperature detection method determines whether the bearing is operating normally by measuring the outer surface temperature of the bearing; The wear detection method determines whether a bearing needs to be replaced by measuring its wear condition.

Predictive preventive maintenance:

5.1 Prediction Method

Predictive maintenance is the process of monitoring the operational status of a machine or component, predicting its future performance degradation and failure, and taking proactive measures for maintenance and replacement. Predictive maintenance can improve the operational efficiency and reliability of equipment, reduce unexpected downtime and maintenance time.

5.2 Preventive Maintenance

Preventive maintenance is a series of measures taken to prevent machine or component failures or performance degradation. These measuresThis includes regular replacement of lubricating oil, checking for loose fasteners, and conducting regular maintenance. Preventive maintenance can improve the performance of equipmentLifetime and reliability, reducing maintenance costs and downtime.
