Equipment vibration fault diagnosis method?
Most equipment vibration faults should be diagnosed from unbalance or misalignment, but in fact, these problems have little influence on equipment vibration faults. In most cases, equipment vibration faults are caused by bearing and gearbox faults.

A, equipment vibration fault diagnosis method (Zunxiang-vibration analyzer)

1, AMS 2 140 vibration band spectrum analyzer; 2.CoCo 80 vibration band noise detector; 3. MAC 800 vibrating belt temperature detector ...

Second, the equipment vibration diagnosis method can be diagnosed from the following aspects:

1, the first thing to look at is the abnormal vibration of the equipment (for example, the vibration amplitude of the equipment is large, the vibration noise is large, and the vibration leads to the high temperature of the equipment).

If the vibration amplitude is large, it should be detected by vibration spectrum; If the vibration noise is large, auscultation noise should be used for vibration detection; If the vibration causes the equipment temperature to be high, the vibration should be detected by temperature measurement.

2. Secondly, eliminate the source of abnormal vibration of equipment (such as loose bearings, misaligned bearings, unbalanced bearings, etc.).

3. Early fault detection-phenomenon before abnormal vibration of equipment

1 & gt; Abnormal function: the equipment is difficult to start, slow to start or even unable to start? The equipment stops suddenly, and the symptoms of this failure are obvious and easy to detect.

2> Overheating and high temperature: If gears, bearings and other parts are overheated, it is mostly caused by insufficient lubricating oil.

3> Excessive oil and gas consumption: Excessive consumption of lubricating oil and cooling water indicates that the technical condition of some parts of the equipment is deteriorating and there is a possibility of failure.

4> Abnormal lubricating oil: The deterioration of lubricating oil is faster than normal time, which may be related to excessive temperature. There are many metal particles in lubricating oil, which are generally related to the friction of bearings, and it may be necessary to replace worn parts such as bearings.

5 > Electrical effect: changes in resistance, conductivity, insulation strength and potential.
